HRS Heat Exchangers

Applications

• Cooling of oils, hydraulic fluids and emulsions using ambient air - especially in the field of mechanical engineering, plant engineering, building machinery and the special vehicle industry
• Used as additional cooler at peak load range (summer) Where water is not available or piping is too expensive

Basic element is an aluminium cooler core (bar & plate construction ) details shown on page 4. Oil tubes are fitted with a turbulence element to ensure an optimum heat transfer. The fan mounted behind the core is usually a suction fan.

To achieve high heat dissipation, the fin arrangement, fan blades and power of engine are harmonised aerodynamically and thermally.
