Temperature is one of the key parameters in oil-hydraulic systems. Oils change their viscosity with the temperature, resulting in different lubricating and adhesion properties. A carefully selected temperature level can also significantly extend the life of the oils.
In return condensers the temporary oil flow causes the cooling capacity to fluctuate. To prevent this effect, a bypass cooler consisting of oil/air cooler with built-in circulating pump is advisable. These combinations ensure a stable oil flow and constant cooling.
The ENK series is characterised by efficient cooling matrices made from high-strength aluminium as well as a compact, simple and affordable design. These are equipped with energy-efficient drive motors combined with sturdy gerotor pumps.
