EC Centrifugal Fans in Air Handling Units (AHUs): Applications and Retrofit Practices

The fan is a key element in stable AHU operation

In a central HVAC system, the air handling unit may not always be the most visible piece of equipment, but it performs several essential functions, including air supply, filtration, heat exchange, humidification and dehumidification.

After outdoor air enters the unit, it passes through filters, coils, the fan section and the discharge section before being delivered into the ductwork. Throughout this process, the fan keeps the air moving. It also has a direct impact on airflow, static pressure, noise and operating energy consumption.

For an AHU, the fan is not just an accessory. If it is oversized, it may lead to unnecessary energy use and noise. If it is undersized, airflow may be insufficient, terminal air supply may become unstable, and indoor comfort can be affected. This is why fan selection should be considered at system level, both in new AHU design and in retrofit projects.

From conventional drive systems to EC direct drive

Many existing AHUs still use traditional AC fans or belt-driven fan systems. These solutions have been widely used for many years and are technically mature. However, as equipment ages, maintenance requirements tend to increase.

Belts, bearings and transmission components need regular inspection. Belt tension and wear can also affect operating stability. At the same time, building cooling and ventilation loads are rarely constant. Weekdays and weekends, daytime and nighttime, occupied and low-occupancy periods all require different airflow levels.

If a fan runs at a fixed speed for long periods and airflow is adjusted mainly through dampers, this can lead to unnecessary energy consumption. EC centrifugal fans offer a practical path toward direct drive, variable-speed operation and integrated control in AHU applications.

EC centrifugal fans help air supply match actual demand

An EC centrifugal fan combines an electronically commutated motor, electronic control and a centrifugal impeller. It is typically designed as a direct-drive solution, reducing the need for intermediate transmission components.

Compared with systems that rely mainly on simple start-stop control, EC fans can adjust speed according to operating conditions. In an AHU system, they can also work with a building management system and respond to pressure differential, temperature, humidity, CO₂ concentration or time-based control strategies.

This allows the AHU to organize air supply according to actual demand rather than operating under a single fixed condition. For hotels, office buildings, commercial facilities, hospitals, laboratories and clean production environments, this type of control supports more refined system management.

New AHU design: Start with Operating Conditions, Not Just Fan Data

In new AHU design, fan selection should not be based on airflow alone. A more reliable approach is to first define the design airflow, external static pressure, filter pressure drop, coil resistance, cabinet dimensions, service access, noise requirements and control strategy. Only then should the fan type and quantity be determined.

Backward-curved centrifugal fans are suitable for AHU structures that require a certain level of static pressure, especially systems with multiple filtration and coil sections. EC plug fans are well suited for cabinet integration, with a relatively direct airflow path and flexible modular arrangement according to the unit size.

During selection, the actual operating point should be positioned within a suitable performance range of the fan, while allowing reasonable margin for future changes in system resistance.

AHU retrofit: not a simple replacement, but a system rematch

A common misunderstanding in AHU retrofit projects is to replace the old fan directly with a new one based only on the original model or size. In reality, after years of operation, filter resistance, coil cleanliness, duct conditions, terminal dampers and control logic may all have changed.

Without recalculating the actual operating conditions, a new fan may not deliver the expected result. Before retrofit work begins, the existing system should be reviewed carefully. Key factors include AHU dimensions, fan section space, service door size, foundation and vibration isolation, power supply, control interface, actual airflow, system resistance and noise conditions.

For AHUs with long operating hours, frequent maintenance requirements or increasing pressure to optimize energy management, fan section retrofit can become an important part of broader system improvement.

Multi-fan arrangements create more options for large AHUs

In large air handling units, a single large fan is not the only possible solution. Multiple EC plug fans can be arranged as a fan wall or a FanGrid-style configuration. This approach offers greater layout flexibility and can help improve airflow distribution across filters and coils.

In applications such as shopping malls, hospitals, data centers and cleanrooms, where continuous operation is important, a multi-fan arrangement can also support more flexible maintenance planning. If one fan requires service, the system can be adjusted according to the project design and control strategy to reduce the impact on overall operation.

The final solution should always be calculated based on airflow, static pressure, cabinet size and control logic.

Control and maintenance determine whether the retrofit works in practice

The value of EC centrifugal fans is not limited to the fan itself. It also depends on how the fan is integrated into the control and maintenance strategy of the AHU.

Through 0–10 V, PWM, Modbus or other control interfaces, EC fans can be connected to a control system for speed adjustment, operating status monitoring and fault feedback.

In real projects, designers should confirm the control interface, signal type, sensor position, operating logic and alarm strategy in advance. If the system uses constant airflow, constant pressure or demand-controlled ventilation, on-site commissioning is also required to verify performance under different operating conditions.

Only when the fan, sensors, control cabinet and building management system work together can the retrofit result remain stable in daily operation.

Blauberg solutions: placing fan selection in a system context

In new AHU projects and retrofit applications, a fan supplier needs to provide more than product parameters. It must also understand the AHU structure, system resistance and control requirements.

With EC centrifugal fans, EC plug fans and related motor solutions, Blauberg can support fan selection discussions based on project airflow, static pressure, installation space and control method, offering practical matching ideas for OEM equipment manufacturers and engineering projects.

For OEMs, the fan solution affects cabinet design, noise control, wiring and maintenance. For retrofit projects, the fan must be compatible with the existing cabinet, ductwork and control system. Looking at the fan as part of the complete system is often more meaningful than comparing product data in isolation.

Optimizing the air handling system starts with the fan

The purpose of an AHU upgrade is not simply to replace an old fan. It is to make the air handling system better aligned with the current operating needs of the building.

EC centrifugal fans provide several technical paths for AHU applications, including direct drive, variable-speed operation, integrated control and multi-fan arrangements. These options give both new-build and retrofit projects greater design flexibility.

Whether the project is a commercial building, public facility, industrial plant or clean production environment, the AHU is expected to operate reliably over the long term. The earlier fan selection is considered in the system design process, the clearer the boundaries become for commissioning, operation and maintenance.

For equipment manufacturers and engineering teams, choosing a suitable EC centrifugal fan solution is, in essence, a way to build a more stable foundation for the entire air handling system.

Axial Fans for Air-to-Water Heat Pumps: Efficiency, Noise and Reliability

In Heat Pump Operation, the Fan Is a Key Gateway to Heat Exchange Efficiency

Driven by the demand for clean heating, building energy efficiency and low-carbon renovation, air-source heat pumps are widely used in residences, apartments, hotels, schools, office buildings, hospitals and commercial buildings. They provide heating, domestic hot water and, in some systems, cooling support. For end users, the performance of a heat pump is not judged only by heating capacity. Energy consumption, nighttime noise and stable operation in low-temperature conditions are equally important.

In the outdoor unit of an air-to-water heat pump, the axial fan organizes outdoor airflow through the evaporator, allowing the air to fully interact with the heat exchanger. Whether the airflow is sufficient and evenly distributed can affect evaporator heat exchange efficiency, defrosting cycles and the overall operating condition of the unit. If the fan is undersized, the heat exchanger may not fully utilize the available heat in the outdoor air, which can increase the compressor load. If the fan is selected too large without proper system matching, it may lead to higher power consumption, increased noise and structural vibration.

Therefore, the heat pump fan is not just a supporting component. It is a key part of the heat exchange system that requires careful matching. It connects overall system efficiency, operating sound level and long-term user experience.

Why Axial Fans Are Suitable for Heat Pump Outdoor Units

Air-source heat pumps need to continuously extract heat from outdoor air. This means the outdoor unit usually requires a relatively high air volume. At the same time, the system resistance of the evaporator is typically within a low to medium range, making axial fans a suitable choice for airflow management.

An axial fan moves air along the axis of the motor. The airflow path is direct, and the overall structure is relatively compact. This makes it easier to integrate the fan with finned heat exchangers, inlet rings, protective grilles and the outdoor unit housing. For heat pump units installed in gardens, on rooftops, on equipment platforms or beside building façades, this structure helps create a stable air inlet and outlet path within a limited installation space.

However, the role of an axial fan in a heat pump is not limited to “providing airflow”. Once installed in the unit, the fan must also support stable air volume, acceptable noise levels, speed control and outdoor operating conditions. In residential and commercial applications, fan performance often influences how users perceive the quality of the entire heat pump system.

Efficiency: From Fixed Speed to Demand-Based Operation

When the fan becomes part of the heat exchange system, efficiency cannot be evaluated only at a single rated operating point. Air-to-water heat pumps operate under changing conditions throughout the year. The required airflow may vary between day and night, early winter and severe cold, heating operation and defrosting conditions.

If a fan runs continuously at a fixed speed, it may cause unnecessary energy consumption and make it harder for the system to maintain appropriate performance under partial-load conditions.

The value of EC axial fans lies in their ability to adjust speed according to heat pump load. Through 0–10V, PWM or communication-based control, fan speed can be adapted to the operating status of the unit. At low load or during night-time operation, the fan can run at a lower speed to help manage energy use and noise. When the load increases or frosting causes higher resistance, the fan can maintain the required airflow to support evaporator performance.

Of course, fan efficiency is not determined by the motor alone. Impeller diameter, blade angle, tip clearance, inlet ring geometry and the available inlet and outlet space all affect the real performance of the fan once it is installed in the heat pump unit. A good laboratory curve does not necessarily mean the same result after integration into the final housing. A mature fan solution should consider the motor, impeller, airflow guidance and the system boundary of the outdoor unit together.

Noise: Details Matter More at Night

Efficiency affects operating cost, while noise directly affects user experience. Air-to-water heat pumps are often installed close to bedrooms, neighbouring windows or shared outdoor areas. During the day, fan noise may be less noticeable due to background sound. At night, however, airflow noise, low-frequency vibration or speed fluctuations can become much easier to perceive.

Noise reduction for heat pump fans should not be judged by a single decibel value alone. Tonality, sharpness, periodic fluctuations and overall sound quality also matter. Blade profile, leading-edge design, impeller balancing, inlet ring matching and motor control strategy can all influence the final acoustic impression.

A well-designed aerodynamic structure helps reduce flow separation and vortex-related noise, resulting in a smoother sound profile. Smooth EC motor speed control can also support reduced fan speed in night mode, helping to limit disturbance to the surrounding environment. For heat pumps used in residential, hotel and commercial projects, low-noise operation has become an important part of product experience rather than a secondary feature.

Reliability: Winter Operation Shapes Long-Term Reputation

While efficiency and noise affect daily experience, reliability determines whether the equipment can operate stably over time. Heat pump outdoor units are exposed to rain, moisture, dust, temperature fluctuations and frequent start-stop cycles. In winter, frost may form on the evaporator surface, narrowing the air passage and changing system resistance.

Under such conditions, the fan needs a certain pressure reserve to handle resistance changes caused by frost, dust build-up or changes in inlet and outlet conditions. After defrosting, condensate drainage, base pan icing or ice accumulation on the grille may also affect the next start-up.

For this reason, fan reliability should not be assessed only by rated data. Bearing life, insulation class, protection performance, material weather resistance, low-temperature start capability and long-term dynamic balance all deserve attention. As R290 and other low-GWP refrigerants are adopted in some heat pump products, the motor structure, control electronics and installation position of the fan also need to be considered as part of the overall safety design.

Selection: From Component Purchasing to System Matching

When selecting axial fans for heat pump applications, manufacturers should focus on several practical questions: Is the static pressure sufficient at the target air volume? Can noise be controlled after installation? Is there enough margin under frosting conditions? Can the speed control method be integrated with the main control board? Are motor temperature rise and bearing life suitable for long-term operation? Are the housing, grille and airflow guidance structure convenient for unit assembly?

These questions are closer to real applications than simply comparing air volume, power and price. The heat pump industry is moving from parameter-based competition toward system-level performance. Whether a fan supplier understands the actual operating conditions of the unit can influence the final product performance.

Blauberg Motoren has long focused on motors and fans, with product directions covering EC, AC and DC motors, as well as axial and centrifugal fan solutions. For heating, refrigeration, air conditioning and ventilation applications, Blauberg can provide fan-matching references from the perspectives of motor efficiency, impeller design, control method and application boundary.

For air-to-water heat pump manufacturers, selecting the right axial fan can help improve overall efficiency performance, manage operating noise and support stable operation in low-temperature environments. A heat pump with a good user experience is rarely the result of one core component alone. It comes from the careful matching of multiple key components. The axial fan is one of the parts that deserves close evaluation.

The Importance of EV Battery Cooling Systems

The battery cooling system is a critical component of an electric vehicle’s (EV) thermal management system, directly influencing battery performance, lifespan, and overall driving safety. As the primary power source for modern EVs, lithium-ion batteries are highly sensitive to temperature fluctuations. Excessive heat accelerates battery degradation and increases the risk of thermal runaway, while low temperatures reduce battery activity, resulting in lower power output and shorter driving range. Therefore, maintaining the battery within its optimal operating temperature range of 25°C to 40°C is essential for achieving reliable performance and long-term durability.

Modern EV battery cooling systems generally fall into three categories: air cooling, liquid cooling, and direct cooling. Air cooling uses fans to circulate air around the battery pack, offering a simple, lightweight, and cost-effective solution that is commonly adopted in entry-level electric vehicles. Liquid cooling, currently the industry’s most widely used technology, circulates coolant through channels or cold plates integrated into the battery pack to efficiently remove heat generated during charging and discharging. Compared with air cooling, liquid cooling provides more uniform temperature distribution, higher cooling efficiency, and greater temperature control accuracy, making it the preferred choice for high-performance and long-range EVs.

An efficient battery cooling system delivers several key benefits. By minimizing temperature differences between individual battery cells, it reduces uneven aging and extends the service life of the entire battery pack. Effective thermal management also enables fast charging by dissipating the significant heat generated during high-power charging, improving both charging efficiency and operational safety. Furthermore, under demanding conditions such as high ambient temperatures, aggressive driving, or prolonged operation, a reliable cooling system helps prevent overheating and ensures stable battery performance.

As the electric vehicle industry continues to advance, battery energy density, charging power, and vehicle performance are steadily increasing, placing even greater demands on thermal management technologies. Intelligent battery cooling systems featuring precise temperature control, adaptive thermal management, and improved energy efficiency are becoming a major focus of future development. Without question, advanced battery cooling systems will remain a fundamental technology for ensuring the safety, reliability, and long-term performance of next-generation electric vehicles.
