This heat exchanger, with a unique design, will make a great addition to your pool system. Made of high-quality stainless steel, this heat exchanger is corrosion-resistant and very durable. It is constructed with corrugated tubes for optimal efficiency. This heat exchanger is used to keep the pool and boiler water separate while providing an efficient means to transfer heat between the two systems. The smooth tube and shell design allow the water to travel through the heat exchanger at a high velocity, which maximises the heat transfer.
