Retrofit | Conversion
Up to 70% energy savings
Efficiently modernise your ventilation installations, on any air handling unit, whatever its brand or age.
Any brand, any age. And if we already know your installation, commissioning, a service call, remote monitoring, the diagnosis starts from what is on record, not from a discovery visit.
Our high-efficiency solutions replace your old systems with modern equipment, delivering up to 70% energy savings and a marked improvement in performance. With a complete range of motors, fans and control systems, Depair offers bespoke solutions to suit every configuration.
Our work is fast, flexible and carried out without interrupting your operations. Integration is simple and universal. Our team masters every stage, from diagnosis to commissioning.
Your unit doesn’t have to be a Depair
Retrofit is not limited to our own air handling units. We work on units of any brand, whatever their age.
A unit we don’t know yet? Same method, with one extra step: a survey visit to measure actual performance and record the casing dimensions and the available electrical supply. The costed report follows.
What decides whether a retrofit is possible is not the brand on the door: it is access to the fan, the room available inside the casing and the existing power supply.
This is the simplest case. Commissioning, a service call, remote monitoring: once we have worked on a unit, its configuration, its fans and its measuring points are known to us. The diagnosis starts from there rather than from a discovery visit, the quotation comes faster, and it is more accurate.
The patented EC-SWAP system makes it easy to modernise your ventilation by replacing the old motor with a more efficient EC motor, without touching the existing wiring or control system, saving energy and reducing noise.
On multi-fan installations, the EC-MULTI gateway takes over: one common setpoint, diagnostics for each fan.
From diagnosis to validation
What’s new
EC-SWAP • EC motor replacement with no rewiring.
EC-MULTI • multi-fan solution for reliability.
The benefits of Retrofit
Bespoke modernisation
Upgrade or replace your fans for a high-performance, quiet system that meets the latest energy standards.
Energy savings
Lower ventilation energy consumption, plus lower operating and maintenance costs.
Safety and reliability
Replacing old fans with modern EC models improves reliability and removes the risks associated with obsolete equipment.
Environmental sustainability
Improved energy efficiency reduces CO₂ emissions and helps protect the environment.
Air quality and health
Our belt-free fans prevent rubber residue in the air: better air quality and lower maintenance costs.
