The C90 range covers outputs from 22 to 90 kW and the C110 range covers 28 to 110 kW. For large commercial applications, these boilers can be supplied in a bespoke prefabricated plant rig.
High-efficiency stainless-steel heat exchangers are combined with low-emission burners in a compact cabinet. The heat exchangers are highly resistant to corrosion and their corrugated pipes provide a massive surface area in a compact space.
Integral pumps are automatically controlled to match water flow to heat output. There is also an integral pump-exercise function. Integral flue check valves prevent reverse circulation of combustion products, and there is also a frost-protection thermostat.
Optional accessories include an external control interface that can directly drive the boilers from a 0 to 10 V signal and an outside sensor connection for an outdoor sensor.
The 100 mm plastic flue system can be up to 30 m long, both horizontally or vertically.
