Cooling Solutions

Excessive heat causes oil viscosity to drop, leading to internal leakage, seal degradation, and component failure. Implementing an effective cooling strategy—whether through air blast coolers or plate heat exchangers—is vital for system longevity.

1. Air Blast Coolers

Utilizing ambient air to remove heat from the oil, air blast coolers are ideal for mobile applications or facilities where water is scarce. They consist of a radiator core and an electric or hydraulic fan.

• Plug & Play: Easy installation with minimal infrastructure.
• Reliability: Robust design suitable for harsh environments.
• Noise: Fan noise must be considered in indoor settings.

2. Water-Cooled Heat Exchangers

For high-power industrial units, water cooling offers superior density. Plate heat exchangers (PHE) provide high thermal efficiency in a compact footprint, while Shell & Tube designs offer lower pressure drops for viscous fluids.

3. Thermal Bypass Valves

Starting a cold system with full cooling flow can damage the cooler core due to pressure spikes (viscous oil) and delay the system reaching operating temp. Use a thermal bypass valve to circulate oil back to the tank until it reaches ~40°C.

"Cooling isn't an accessory; it's a life support system. A 10°C rise above 60°C cuts oil life in half."
