The P&H Mine Air Systems 24VDC high-capacity remote compressor/condenser (HCRC) is a mounted system designed to be a replacement for conventional engine-mounted, belt-driven compressor/condenser systems. The unit can be mounted a wide variety of mobile diesel-powered mining equipment, including:

  • Haul trucks
  • Graders
  • Dozers
  • Front-end loaders

The HCRC is designed to integrate with the existing OEM air conditioning system and uses the existing dash-mounted EOM evaporator coil, blower, ducting and vents. The system can be mounted close the operator cab and be easily integrated after the original AC unit and the longer refrigerant lines are removed.

The HCRC features:

  • Two quick-disconnect ports for the shorter, relocated refrigerant lines
  • Two plugs for the control power

A variety of kits are available to make installation quick and easy for many popular mining machines, including those with pre-engineered roof racks that are ROPS/FOPS friendly. If the unit ever needs to be replaced, the change-out process can be completed in approximately 30 minutes with the proper tools and equipment.
