Brazed plate heat exchanger Plate material: stainless steel AISI 316L Brazing material: Copper 5x12 plate specs Max pressure 652 lbs. per sq. in Test pressure 971 lbs. per sq. in Volume per channel (L) 0.05 Exchange area sq ft. .417 per plate Max Temperature 437F These are used for transferring heat from one hot water source to another without mixing the two different water sources. For example when hooking up a non pressurized furnace to an indoor boilerorfor heating cold water before it goes into the hot water heater to eliminate the need for fuel to power your water heater. They are good for preheating water to waterheaters and for transferring heat from an outdoor furnace or solar system to an indoor boiler. Other uses for them include transferring heat from hot oil or cooling milk off a milk pipeline. Sizingyour plate depends on several factors. Plates have BTU ratings of approximately 4 000 BTU per plate ie a 10 plate is40 000 BTU and a 40 plate is 160 000 BTU. These ratings work very well for infloor heating but if you are hooking to an indoor boiler you will want to use a larger plate to do the same thing.A good rule of thumb is to look at the rating plate on your indoor boiler and find the BTU rating for it. Then add 50% tothat and use that for the BTU rating to select your plate.Another way to figure plate size is 10 plates for every 500 square feet. Platesshould be mountedvertically but can be placed horizontally if space does not allow Allplates come packed in foam to prevent damage during shipping.
