Oil Cooling & Filtration

Extend service life, prevent failures: The quality of the hydraulic oil is the decisive factor for the cost-effectiveness of your machine. In this category, you will find everything for thermal management and cleanliness of your system – from high-performance coolers to effective filtration.

Two Pillars for System Protection

Heat and dirt are the most common causes of hydraulic component failure. We offer solutions to combat both:

1. Thermal Management (Oil-Air Coolers)

Oil that is too hot (above 80°C) destroys seals and causes the lubricating film to break. We rely on the market leader asa hydraulik:

  • Standard Coolers (TT Series): Proven plate heat exchangers for return lines or bypass circuits (up to 26 bar).
  • The Innovation (H-Cube): A smart combination of tank, cooler, and filter in one component – saves space and piping.

2. Filtration Technology (Contamination Control)

Over 80% of all hydraulic failures are due to solid particles in the oil. Our filters for the low-pressure range (up to 20 bar) protect the system at critical points:

  • Return Line Filters: Clean the oil before it flows back into the tank.
  • Suction Filters: Protect the pump from coarse debris from the tank.
  • Spin-On Filters: Maintenance-friendly screw-on filters for quick changes in the field.

Retrofitting Cooler or Filter?

Are you planning a new power unit or want to retrofit overheating mobile hydraulics? Use our inquiry function! We will help you calculate the required cooling capacity and select the appropriate filter size.
