Selection Criteria
When specifying an industrial oil cooler, define:
- Required heat load (kW)
- Oil flow rate (L/min)
- Oil type and viscosity
- Maximum operating pressure
- Oil inlet and desired outlet temperatures
- Cooling medium (air or water)
- Ambient or cooling water temperature
- Installation space and mounting orientation
- Electrical supply (for air-cooled units)
For a specific recommendation, provide:
- Heat load (kW) or equipment power
- Oil flow rate (L/min)
- Oil type (e.g., ISO VG 46 hydraulic oil)
- Inlet oil temperature
- Target outlet temperature
- Cooling medium (air or water)
- Operating pressure and ambient conditions.
