Flat Plate Heat Exchangers


Brazed Flat Plate Heat Exchangers were developed years ago and they are now the most widely used device for isolating hydronic heating circuits. The Brazed Flat Plate Heat Exchangers transfer heat from one liquid medium to another with no intermixing of the two fluids. It requires the fluid to be pumped into both sides of it at once. The flat plage heat exchangers we sell can transfer up to 240,000 BTU’s per hour. The amount of heat transferred is dependent on the delta T (difference of temperature between the two fluids). It also depends on the amount of fluid moving through both sides of the heat exchanger. Flat Plate Heat Exchangers are required for all radiant heating systems where you mix heating water with domestic water. Well - not required everywhere. But, in most places it is and for places where you can mix heating and domestic water - you should never ever mix the two. Thus, use a flat plate heat exchanger for all open loop heating systems!
