Evans Cooling Systems, Inc. products

Evans HDTC is the waterless cooling solution for heavy duty diesel applications. It features a huge separation between the operating temperature of the coolant and its boiling point. HDTC can control metal temperatures at coolant temperatures that are well above the boiling point of water. With engine metals protected at higher coolant temperatures, fan turn-on temperatures can be safely increased. Released from the burden of avoiding the boiling point of water, HDTC waterless coolant enables the safe use of higher coolant temperatures and sharply reduced fan usage. Thousands of dollars in fuel savings annually result from that technique.
