Features and Benefits

Wide range of outputs

Available in 160, 200, 250 and 300 kW models

Modular design for any space

All connections and pipework enter the top so Gas 220 Ace models can be positioned side to side or back to back

A more stable and reliable design

The monobloc heat exchanger is built from a single piece of aluminium which makes it inherently more stable and reliable

Lightweight and manoeuvrable

Supplied with integral wheels so it can be delivered through a standard door and lifts, plus easy to manoeuvre within plant rooms

Total control as standard

A specially designed microprocessor is at the heart of the control system with time and temperature controls supplied as standard, set and controlled by the end user

High efficiency

High efficiency up to 97.7%
