The B8DW unit is the most compact double-wall unit optimized for small to medium capacity applications. Double wall technology ensures that fluids do not mix by protecting one circuit from contamination in the event of internal leakage if a channel plate for any reason breaks.
The protective double wall prevents any hazardous fluid from entering the water side and instead it will be drained outside the heat exchanger.
The technology provides safety assurance in a range of applications, including tap water stations, where the potable water side must be protected from poisonous glycol, or dirty water from the district heating grid. Other applications where fluids must not mix include heat pumps, boilers, transformer cooling, desuperheaters and heat recovery from air compressors.
Double wall technology is mandatory in such applications in some countries, including BeNeLux, France, Canada and Australia.
Hampus Castengren, SWEP Segment Manager, District Energy said
“SWEP is the market leader in the thermal efficiency of double wall exchangers. With the launch of the compact B8DW to join alongside the existing B16DW medium -size range and the B35TDW large range, we can offer a double wall technology with high thermal length for all sizes and types of heat recovery applications that calls for tight temperature approach and required leak protection.”
