technical information

The INTERNORMEN-Purifier-Systems (IFPM / IFPS) remove water, particle contamination and gases from hydraulic and lubricating fluids.There are mobile and stationary systems offered, represented by IFPM 21, IFPM 31, IFPM 71, IFPS 71 and IFPS 101.

Due to the reduction of fluid ageing, the maintenance of lubricity and the decrease of the air- and water content, the equipment reliability of the whole system and the durability of the used fluids is improved. Furthermore due to the dehydration the acidification is reduced, and this prevents the corrosion in the fluid system. Acids arise from hydrolysis of the fluid. Metal particles within the system accelerate this process due to their catalytic properties

The IFPS/IFPM remove the highest possible rates of free water, free gases, dissolved water and dissolved gases. The particle contamination is removed in the fluid outlet filter. The fineness of filter - ranging from very fine to coarse - is selected according to the respective kind of contamination. Thus the cleanliness of the fluid required for the respective application is reached.

operation principle of the IFPM / IFPS :

The fluid to be purified is sucked into the purifying system by a vacuum generated by a vacuum pump.
It passes through a small heatable tank with a 3000 Watt heater. Thus the fluid is preheated to the operation temperature which is adjustable by the electronic control device. At the set temperature the heating automatically turns off. A defined quantity of fluid is lead through a solenoid valve into the vacuum chamber. The incoming fluid diffuses over dispersal material therein which enlarges the surface area of the fluid. Free and dissolved water vaporises due to the decrease of the boiling temperature of the water in the vacuum.
Ambient air is let into the vacuum chamber through an air filter and a throttle valve. This air moves upward against the flow of the fluid. Water and gas join in the upward air flow and - after leaving the vacuum chamber - enter the vacuum pump. From there the water-gas mix is conveyed into a receptacle of condensate, respectively vented to the atmosphere.
