Nanaimo, British Columbia – VMAC is releasing a new state-of-the-art PTO driven technology that it says will set a new standard for air compressor and hydraulic multi-power systems.
VMAC has released its Mounted Multi-Power System, the DTM70-H. This system is designed as a configurable, all-in-one solution for service trucks fitted with hydraulic cranes or other hydraulic components. It also provides powerful air-on-demand capability.
The DMTM-70 features a priority valve and an intelligent throttle control system to allow for air-on-demand with increased CFM output. This throttle control technology is currently used in UNDERHOOD™ air compressors. It was challenging for VMAC to implement variable air flow on an air compressor that is integrated with a hydraulic system, because of the need for steady flow rate in many hydraulic systems. VMAC’s hydraulic bypass circuit contains a priority flow control valve, which diverts excess hydraulic flow back into the reservoir tank before it reaches the crane. “Cranes require steady hydraulic flow, while air systems can benefit from adaptive air-on-demand control, providing maximum air flow only when it is needed. Combining both these functions into one sophisticated system gives operators the best of both worlds,” said Chris Moyse, Engineering Lead for the DTM70-H.
This system allows operators to switch between fixed and variable operating modes. Fixed mode maintains a pre-set low engine RPM for running hydraulic equipment and providing a steady rate of compressed air. Variable mode enables engine RPM to increase and decrease automatically based on air demand, while still maintaining steady hydraulic flow.
