EC Fan Upgrades

Retrofitting EC plug fans to replace traditional belt-driven fans and motors offers several advantages for HVAC systems. Enhance HVAC efficiency with HALO HVAC by upgrading to EC Fan technology.

Enhanced Energy Efficiency

EC plug fans, driven directly by an electric motor, ensure heightened efficiency by eliminating energy losses from belt friction and slippage. EC fans feature variable speed control through EC motors, allowing precise airflow adjustments and reducing energy consumption at optimal speeds. These fans also provide redundancy in multi-fan setup.


In contrast to belt-driven fans, EC plug fans have fewer moving parts, necessitating minimal maintenance and resulting in lower operational costs.  Furthermore, these fans operate with reduced noise levels, especially at lower speeds, making them ideal for environments where noise minimization is essential.

Cost-Effective Maintenance

There are multiple points of failure with belt driven fans. Such as, belts, pulleys, bearings, anti-vibration mounts and motor problems.


Upgrading to EC fans eliminate these points of failure, and the need for regular maintenance associated with belt-driven fans, such as belt adjustments and replacements. 


This leads to significant savings in maintenance costs over time. With fewer moving parts, Upgrading to EC fans also reduces the probability of breakdowns, minimizing ongoing maintenance efforts.

 Simplified Installation and Control

HALO HVAC make the upgrade to EC fans a straightforward process. We deliver a seamless replacement for existing belt-driven fans, minimizing disruption during installation. Once installed, EC fans can be configured to run at a fixed speed or modulated based on specific requirements. Customized control strategies offer further opportunities for reducing energy consumption.


EC fans compact design facilitates space savings and easier installation, particularly advantageous in limited-space applications. EC (Electronically Commutated) fans are designed with built-in electronics that allow them to operate using DC (direct current) power. As a result, they don't require an additional inverter, which is typically used to convert DC to AC (alternating current) or vice versa.

For individuals managing multiple air handling units (AHUs) or HVAC systems, adopting EC fans presents a compelling opportunity to achieve a tangible return on investment. Emphasizing energy efficiency and reducing maintenance costs not only leads to substantial long-term savings but also elevates the reliability and performance of the entire system.


Moreover, this transition aligns with a commitment to carbon reduction, contributing to a more sustainable and environmentally friendly operation.

AHU Refurbishment Services Overview;

Mechanical & Electrical  

HALO HVAC provides a comprehensive suite of services as part of an AHU upgrade, specializing in mechanical and electrical  installations for both commercial and industrial settings. 

Controls & BMS Mods


HALO HVAC ensure energy efficiency and future adaptability. With seamless integration into Building Management Systems (BMS) our HVAC services provide centralized control guaranteeing a smart, sustainable solution for evolving control needs. 

EC Fan Upgrade


Switching to EC fan arrays enhances efficiency, resulting in significant energy and CO2 savings. These fans also provide redundancy in multi-fan setups and require easy maintenance without traditional components like belts and pulleys.


Replacing or repairing dampers and actuators in damaged areas ensures the restoration of airflow set-points while minimizing pressure drop.



Replacing worn or damaged coils is essential for restoring optimal performance. Over time, changes in set point parameters may necessitate the installation of new coils that are heat pump ready.

Filters & Air Treatment


Upgrading your filters and housings in line with ISO 16890 can significantly improve IAQ, system pressure drop, and energy consumption, reflecting a commitment to advanced technologies and overall system efficiency.

Clean Room & Labs, Chandlers Ford 

13 Air Handling Units serving a critical manufacturing process and science laboratories, all requiring refurbishments, controls and BMS modifications, delivered in a specific time frame, whilst achieving 26t a year CO2e reduction.

5 Star Hotel, Knightsbridge, London

The belt driven fans within the air handling units at this hotel had failed, resulting in no ventilation to several areas of the building including the toilets and the kitchen. It was imperative that the ventilation was reinstated as a matter of urgency to ensure the Hotel was fully operational & compliant.

Offices. Gracechurch Street, London 

With the building owners advertising for new leases a key objective was to ensure the indoor environment is comfortable and healthy. Over time, the existing AHUs became less efficient, leading to higher energy bills and reduced indoor air quality.
