High efficiency gas fired unit heaters
Dravo, a division of Johnson & Starley, has introduced a new range of high efficiency gas fired unit heaters.

All 20 models incorporate pre-mix burner technology resulting in exceptional low exhaust emissions i.e.no emissions of CO (Carbon monoxide) and NOx (Nitrogen oxide) lower than 30ppm class 5, in complance with EN 1020 2009 standards
The Condensing range is also registered on the Governments Energy Technology list, qualifying for the Enhanced Capital Allowance for companies investing in high efficient technology. Operating costs are further reduced as these units are said to also have an exceptional low temperature rise compared with other units minimising heat stratification
- Longevity is guaranteed as both the combustion heat exchanger and seconday tube bank assembly are made entirely of INOX AISI 441 stainless steel.
- Robust frame with double layer top, side & bottom casing panels with air insulation gap, large burner housing for easier service & maintenance access with hinged door that easily be removed.
- Rigid fan assembly with special high efficiency Hydria-Rotomatika fan with aerodynamic blades complying with current ErP requirements
The range consists of three high efficient models:
The Regulair LR On-Off & Hi-Lo Series
7 Models with a heat output from 15-92 kW operating up to 94% nett thermal efficiency
The Modulaire LP Modulating Series
7 Models fully modulating with a heat output range 12-92 kW operating up to 94% nett thermal efficiency
The Condensaire LK Condensing/Modulating Series
6 Models fully modulating with a heat output range from 5-97kW operating up to 108% nett thermal efficiency
