Gardner Denver Transport Solutions’ Hydrapak Hydraulic Oil Coolers are engineered for the demands of truck‑mounted hydraulic systems, where stable oil temperature and reliable cooling are essential for continuous operation.
Instead of relying on large 200–300 litre hydraulic oil tanks, Hydrapak uses a compact, high‑efficiency heat exchanger to manage heat with a much smaller oil volume.
We integrate the Hydrapak across our packaged solutions, including compressors, blowers, vacuum exhausters and pumps. The system can be configured for LPG, cryogenic, aviation fuel and petroleum pumps, and is also used in walking floor applications where compact, dependable cooling is required.
Hydrapak technology delivers a balanced combination of efficiency, performance and space savings:
For modern truck hydraulic systems, Hydrapak offers a smarter, more efficient alternative to oversized hydraulic oil tanks.
Traditional hydraulic installations depend on oil mass to absorb heat. While simple, this approach consumes chassis space, adds weight and increases service costs.
Hydrapak replaces the tank with a compact cooling unit that delivers consistent temperature control without the drawbacks of oversized reservoirs.
Hydrapak units take up far less space than conventional tanks, giving OEMs and bodybuilders more flexibility when positioning truck‑mounted equipment.
The compact layout simplifies installation and frees up room for other components.
A 200–300 litre tank requires the vehicle to carry the full oil volume at all times.
Hydrapak systems operate with dramatically less fluid — as little as 11 litres on the HK3 — reducing overall system weight and enabling higher payload capacity.
Optimised air‑cooling and efficient flow paths maintain stable hydraulic oil temperature, even under demanding duty cycles.
The reduced oil volume allows faster heat transfer and helps the system operate efficiently with lower energy demand from the hydraulic pump.
With significantly less hydraulic oil in the system, annual service becomes faster and more economical:
This makes Hydrapak a cost‑effective solution for fleets and industrial operators.
