Profile: Plate Concepts, Inc. specializes in designing and producing plate and frame heat exchangers. Our plate & frame heat exchanger is widely considered the suitable type of heat transfer equipment. We serve the industries such as air conditioning, amine exchangers, extrusion line cooling, polyol coolers, diesel oil cooling, oil heating/cooling, steam heating and wash oil coolers. Our double wall plate heat exchanger provides extra protection against cross contamination of the process fluids. Each double wall plate actually consists of two identical plates, seal welded together at the 4 port openings. A small air gap between each plate pair vents to atmosphere, so that if a leakage does occur, it will be vented between the double walls for immediate visual detection.
