Copper brazed plate heat exchangers provide efficient heat transfer with a small footprint. They are also maintenance free, provide a long service lifetime and can withstand high temperatures and extremely high design pressures. They are used in a range of duties including cooling, heating, evaporation, condensing, in numerous applications like HVAC, refrigeration, heat pumps, air conditioning, process heating/cooling, oil cooling and solar heating. In addition, tantalum treated BHEs can be used in process industries that handle highly corrosive media.
