On Site Refurbishment

Not every failing or underperforming Air Handling Unit (AHU) needs to be replaced. At Klensys , we provide cost effective on site refurbishment services for a wide range of AHU types and brands, helping you get the most from your existing equipment.

Our refurbishment service can include:

Refurbishing an existing AHU can bring significant savings compared to a full replacement.

Work can often be carried out in situ, avoiding the need for cranes, heavy lifting equipment, or structural changes.
Refurbished or replacement components can be flat packed and delivered on pallets, allowing easy transport through goods or passenger lifts—even to upper floors—minimizing disruption in occupied buildings.

✅ Cost effective and sustainable

A well maintained AHU typically has a service life of around 20 years. With a proper refurbishment—retaining the existing casing and frame—you can add up to 10–15 more years of reliable operation, provided regular maintenance continues.

✅ Improve performance and efficiency

Our engineers can refurbish or replace key components that directly impact performance and energy efficiency, including:

Coils
Controls
Dampers
Fans
Filters
Heaters
Thermal Wheels

✅ Enhance compliance

Many older AHUs may not meet current standards or regulations. Through refurbishment, Klensys can help upgrade your unit to meet modern safety, construction, and operational standards, giving you peace of mind and improved performance.

Klensys On Site Refurbishment services offer a smart, cost effective alternative to full replacement—helping you save money, reduce downtime, and support your sustainability goals.
