The MHX Hydrapak Series from Gardner Denver is the industry’s most compact, pre-engineered hydraulic oil conditioning system for transport applications. Originally developed from Gardner Denver’s pioneering hydraulic cooling technology introduced in 1983, the MHX Hydrapak continues that legacy with a patented, space-saving design that requires no additional frame rail clearance for airflow.
- Patented ultra-narrow design (less than 8.9 in. wide)
- No additional frame rail space required for cooling airflow
- Hydraulic flow rates up to 30 GPM
- System pressure capability up to 5,000 PSI
- Integrated 3.4-gallon hydraulic reservoir
- Lightweight, stainless steel construction
- Direct frame-rail mounting (driver or passenger side)
Designed for crowded modern tractors, the MHX Hydrapak delivers efficient cooling, reduced weight, and simplified installation in a single integrated package. With a width of less than 8.9 inches, the MHX Hydrapak is a compact, lightweight hydraulic oil cooling system that overcomes one of the most common installation challenges; limited space, without sacrificing cooling performance or serviceability.

Most Compact in Its Class
Patented narrow design allows installation where traditional hydraulic coolers simply won’t fit.
No Airflow Clearance Required
Eliminates the need for additional space around the unit, simplifying installations on crowded chassis.
Lightweight, Integrated Design
Substantially lighter than standard reservoir-based systems, helping increase payload capacity and revenue.
Durable Stainless Steel Construction
Robust stainless steel housing with a 7-gauge mounting plate and frame-side gussets for strength and longevity.
Maintenance-Friendly Access
Removable lid and side panels provide easy access to filters, oil fill, and internal components.
Environmentally Responsible
Smaller oil volume reduces environmental risk and the potential impact of large oil spills.
