Hydraulic drives and lubricating systems are indispensable in machine construction, raw material production, navigation, and many other areas. Both as a power transfer medium and lubricant oil is heated by friction losses during operation. Since the viscosity of the oil changes along with the temperature, precise temperature stabilization using coolers is a vital requirement for systems and drives for consistent power. In addition to the unlimited supply of ambient air, water is also used as a coolant. The advantage of water is the low susceptibility to seasonal temperature fluctuations and large companies often use it as a central circulation coolant. BWT plate heat exchangers are a particularly efficient solution in these cases. They’re extremely compact, practically maintenance-free, and easy to install.
