How Hydraulic Oil Coolers Work

Hydraulic oil coolers function like radiators, transferring heat from hydraulic oil to ambient air. Oil flows through internal tube networks, releasing heat across finned surfaces. This maintains optimal viscosity, prevents component wear, and ensures system reliability. Without proper cooling, hydraulic systems risk overheating, reduced efficiency, and costly downtime.

Industries Served

  • Chemical & Crude Oil Transport
  • CO₂ & Food Delivery Trucks
  • LP Gas Services
  • Industrial Fleet Applications

Paragon coolers are engineered to meet the rigorous demands of modern transport and industrial environments.
