Typically, water cooling applications calls for non-corrosive materials. Our HT-Series or 550's are as versatile as it comes. Straight-tube. U-tube. Fixed or removable tube bundles. All nonferrous shell side. For larger heat loads, or "close-approach" applications, our line of plate and frame exchangers will provide a more compact, probably more cost-effective selection. For clean water applications, we recommend our compact brazed plate heat exchangers. Stainless steel plates. Copper or nickel brazing. Extremely rugged. Very compact.
