Plate heat exchangers are designed for optimal performance. Stainless steel plates with densely packed surface areas provide excellent thermal efficiency. Heat exchangers use up to 80% less floor space and often weigh 10 times less than shell-and-tube exchangers. Additionally, they use less surface area to transfer the same heat, which makes them easier, safer, faster, more efficient and more economical to ship, handle, install and use.
