  4. Retrofit project with ECFanGrid involving two AHUs at a dairy factory

Retrofit project with ECFanGrid involving two AHUs at a dairy factory

Tuesday 07 April 2026

UTAS refurbishment and energy-saving projects

Today we’re sharing details of the refurbishment of two air handling units for a dairy and fresh produce manufacturing plant in the agri-food sector, carried out by our partners at Rosenberg France.

The company had two objectives with this refurbishment of the units:

  1. Energy savings. This is the key feature of the compact EC PlugFan fan modules, thanks to their electronically commutated motors.
  2. Process reliability thanks to system redundancy; this provides a non-stop system that ensures nominal flow and pressure performance, without compromising the operating point, even in the unlikely event that one of the fans fails.

The agri-food industry cannot afford failures in ventilation systems that could disrupt production. Redundancy in the AHUs guarantees a level of peace of mind that traditional mechanically driven fans do not provide.

BEFORE

AFTER

 

 

In this project, the belt-driven fan was replaced by a configuration of six aluminium motorised turbines (AIMg3) with a diameter of 500 mm, providing airflows of over 50,000 m³/h.

Airtècnics supplies the complete retrofit kit, so that the end customer does not have to worry about anything during the process, and delivers a ‘turnkey’ installation, which includes:

  • Fans
  • Adaptation profiles
  • Installation accessories
  • Electrical junction box
  • Constant flow and pressure control

BENEFITS OF ECFANGRID

The project has resulted in an actual reduction of over 30% in electricity consumption, with an equivalent operating point in each AHU.

  • Reduced Maintenance: By eliminating drive belts, pulleys and lubricants, common mechanical failures are eliminated and the need for maintenance is reduced.
  • Easy Installation and Compact Design: The lightweight components facilitate handling and transport, allowing for quick (“plug & play”) installation in confined spaces.
  • Noise Reduction: EC fans operate more quietly, improving the acoustic environment.
  • Adaptability: Allows the number of fans to be adjusted to the specific air flow demand by reconfiguring the array.

As a result, a retrofit project causes minimal disruption to the customer. Your unit is taken offline for just a few hours, with all work carried out by our engineers and installers from start to finish.

If you need to upgrade your AHUs, please do not hesitate to contact our specialist sales team, who will assist you with your enquiry without obligation.
