The Powerbox PB63 SNG Combined Heat & Power unit generates 63 kW(e) for use on site with 111kW(th) thermal energy being available for space heating and domestic hot water production. The PB63SNG is a thermally modulating CHP unit that will adjust its power output automatically dependent on the buildings thermal load demand (<32kW(e) +/- 3%)

The PB63SNG is designed and manufactured by Helec with build partners in UK and Denmark factories enabling this unit to be customised specifically to the clients’ needs and expectations when plant room floor space may be at a premium, extra low NOx emissions are required and low sound power levels require additional sound absorption to run as quiet as possible.

Fuel type is Natural Gas with LPG available if required. (Always ask for confirmation of specification required at time of enquiry)

Typical applications where Powerbox CHP units are well suited and in place are in hotel plant rooms, residential district housing schemes, leisure centres and residential care home. (see case studies)
