Key Features
Model Range
NEXT-G
A range of modulating heat output condensing gas unit heaters with fixed air flow AC fans.
NEXT-G EC
An extended series of condensing gas unit heaters modulating both the heat output and ventilation, equipped with electronically controlled fans. This model gives you:
- Lower noise levels
- Lower energy consumption
- Constant outlet air Delta T
- Fixed or modulating air flow
Next-G C
A range of modulating heat output condensing gas unit heaters with centrifugal fixed air flow fans.
- LPG gas conversion kit
- Condensate drain siphon
- Room temperature sensor
- Duct connection flange for C models (with centrifugal fan)
Ideal for efficiently heating workshops, industrial, and commercial buildings. The system’s modularity makes it perfect for places where no flammable materials are present.
