Products Features
1) Durable
Patented design - fully closed oil tank and breathing bag, to reduce the changeable frequency of hydraulic oil, enhance the lifetime of hydraulic elements. Electric control and hydraulic system standard components are from international brand products of reputation, lower fault rate, easy to maintain.
2) Environment protection
Employing patented overflow and off-load combination control and accumulators, to ensure lowest hydraulic oil temperature, the energy consumption of entire device will reduce at 80%.
3) Flexible
Adopting modular skid-mounted design, reserve rig integrated control interface, to meet the modification demands of re-building and customization. Providing various type of products under different conditions, also customized design is optional.
4) All models equipped with temperature control system, greasy dirt testing system and alarming system, remote control / local control can be switched. Remote pressure monitoring function is optional.
5)Patented breathing bag
JJC patented breathing bag is made of special material and manufactured thru excellent technology, the shape is cuboid or pillow type structure, it is installed in auxiliary oil tank, and form one closed oil tank system.
6)High cleanliness
During the working process of HPU, oil tank breathing bag shrinks and expands, interior and exterior pressure of oil tank in balance, and the hydraulic oil in oil tank is isolated from exterior air, therefore, it effectively ensures the purity of hydraulic oil, and extend the lifetime of hydraulic oil.
