Water Compact

In contrast to heat-transfer oil, water used as a circulating medium provides numerous physical and economic benefits – particularly for high operating temperatures. The heat transfer characteristics of water are far superior to those of oil: its high specific heat transfer capacity is second to no other liquid media. Water also provides many ecological benefits.

The K and KN sizes of the Water Compact product family are equipped for operation far above the atmospheric boiling point with temperatures of up to 180 °C. They meet the most stringent safety requirements. The systems are extremely compact and are built exclusively with high-quality components.
