    J2SK JSK J2BE closed cycle units

    Range of use


     J2SK/JSK/J2BE closed cycle units include: vacuum pump, gas-liquid separators, heat exchangers, circulating pumps, accessories such as control systems, etc. Since other working liquid additional to water can be used (i.e. the liquid whose saturation pressure is less than water such as ethylene glycol, transformer oil), the application scope of vacuum pumps is effectively increased and at the same time, the common liquid-ring vacuum pumps such as 2SK, SK, 2BE are prevented form abundant discharge of working liquid in vacuum pump because of the actual application of pumping some gases which would pollute the working liquid, and the use cost of the customers are reduced.
    J2SK, JSK, J2BE closed cycle unit can completely separate the exchange between the technological gases and the air environment and discharge the technological gases into designated locations to avoid damage to the environment. It is especially suitable for the extraction of flammable, explosive and poisonous gases.
