RMF Systems Maxi Water VAC

RMF Systems Maxi Water VAC vacuum dehydration units are designated oil purification units which can be applied directly to various types of machine reservoirs. The units dehydrate and clean most types of oil such as lubricating, hydraulic, transformer and switch oils by removing particles, gasses, and water. The purified oil satisfies the most stringent quality requirements, such as stated in the ISO 4406.

The Vacuum Dehydration Units neither remove nor alter oil additives. The water removal process is based on pure vacuum evaporation inside a vacuum chamber at a maximum temperature of 60 °C. Solid particle removal is achieved through a well proven RMF Systems micro filter.

The dehydration units do not require continuous attention whilst operating. Once the dehydration units are connected properly and commissioned, oil purification is a semi-automatic process. The desired oil temperature can be selected on a thermostat which is included in the integrated heater element of the dehydration units. Oil supply and removal from the vacuum chamber is a full automatic process which is controlled by a PLC. Overflow of the waste container or tank is protected through a float switch which will shut down the dehydration unit once the maximum level is reached. The only manual action is the emptying of the pre-condenser and waste water container (depending on model).

The Vacuum Dehydration Units remove liquid, gas and solid contamination, which are corrosive and contribute to the reduction of machine life. Water, gas and solid particle contamination greatly increase maintenance costs and contribute to unwanted break downs or total machine failures. The Mini Water Vac and Maxi Water Vac offer protection against malfunctions, break downs and total failures. The dehydration units also protect the environment by reducing oil consumption and oil disposal along with its inherent costs and problems.
