EVOLVING AHU RETROFIT SOLUTIONS

How modern retrofit controls compare to traditional AHU upgrades...

Traditional AHU upgrade approaches often focused only on replacing failed components or maintaining ageing controls infrastructure. While these systems provided basic functionality, they frequently lacked modern connectivity, intelligent optimisation, remote visibility, and scalable integration capabilities required by today’s buildings.

Traditional AHU Retrofits

Challenges commonly found in legacy retrofit projects:

Limited remote visibility and monitoring capabilities.

Older systems often require on-site interaction with little or no access to live operational data remotely.

Complex integration with modern BMS infrastructure.

Additional hardware, gateways, or engineering time may be required to connect legacy controls into modern building systems.

Higher installation time and increased wiring complexity.

Traditional retrofit methods can involve extensive panel modifications, rewiring, and increased labour costs. 

Minimal optimisation and limited energy intelligence.

Legacy systems typically lack advanced monitoring, energy analytics, and intelligent control strategies.

Difficult future scalability and upgrade limitations.

Older platforms can become increasingly difficult to support, expand, or integrate with evolving building technologies.

Most existing Air Handling Units can benefit from a retrofit solution, particularly systems with ageing controls, limited monitoring capability, inefficient operation, or unreliable components. Our engineers carry out a detailed site assessment to evaluate the current infrastructure, identify improvement opportunities, and recommend the most effective upgrade strategy for your application.

Yes. Modern intelligent controls can significantly improve AHU efficiency by optimising fan speeds, valve control, scheduling, temperature management, and airflow strategies. By reducing unnecessary energy consumption and improving system responsiveness, retrofit upgrades can help lower operational costs while improving overall building performance.

The iACS retrofit solution is designed with flexible integration in mind and can support communication with a wide range of Building Management Systems. Our solutions can provide improved visibility, alarms, trend logging, remote monitoring, and enhanced control functionality while working alongside existing site infrastructure. 

Retrofit projects are designed to minimise disruption wherever possible. Because the existing AHU infrastructure is retained, upgrades can often be completed faster and with less downtime compared to full unit replacement. Our team works closely with site operators to plan installation and commissioning around operational requirements.

Yes. One of the key advantages of a retrofit approach is the ability to modernise the controls system while retaining the existing AHU mechanical structure where suitable. This allows buildings to benefit from modern intelligent automation, improved efficiency, and enhanced monitoring without the capital cost of complete AHU replacement.

Following installation and commissioning, iACS provides ongoing technical support, optimisation reviews, maintenance assistance, and performance monitoring services. Our aim is to ensure each retrofit solution continues to operate efficiently while delivering long-term reliability, operational stability, and energy savings.
