Technical Advantage
High performance semi-hermetic dual-compressor screw unitIntroducing the modern fourth generation of highly efficient rotor profile and special advanced KAPP rotor milling lathe, ensuring higher processing precision and working efficiency, improving the reliability of compressor operation.
Falling Film Evaporator with highly effective heat transfer performanceThe heat transfer performance of falling film evaporator is about 30% higher than flooded evaporator. Introducing special designed distributor and processing technology, the liquid refrigerant on the surface of heat exchange tube in the falling film area can be evenly formed into the film, which has a great advantage over boiling evaporation.
Widely applicationThe chiller can realize excellent performance not only in normal chilled water application, but also in -20°C outlet chilled water and over 80°C outlet hot water.
Environmental friendly and energy saving

Adopt R134a which has no damage to the ozone layer. Refrigerant charging quantity: 0.20~0.25kg/kW, 30-40% less than flooded compressor unit, which can fully reduce the greenhouse effect.
Among the alternative refrigerant which can replace R22, working pressure of R134a is about 50% lower than R404A and R507. The rotor leakage is reduced because of low pressure difference of R134a compressor, and the adiabatic efficiency and volumetric efficiency are improved compared with R404A and R507. The theoretical cycle efficiency of R134a is 12% higher than R404A and 6% higher than R507 on average, which is an obvious advantage of energy-saving over R404A and R507. Therefore, although the cost of R134a unit is higher than that of R404A and R507 due to the low refrigerating capacity per unit of swept volume, the BingShan falling film refrigerating units still have a full range of products with R134a refrigerant.
The energy efficiency ratio of LS series falling film semi-hermetic screw water chiller is above grade I or Hof national regulation GB19577. Due to the small temperature difference between glycol/brine outlet temperature and evaporating temperature, the energy efficiency ratio of YC/YS series falling film glycol/brine unit is 12-15% higher than dry glycol/brine unit and 5-10% higher than flooded glycol/brine unit.

Stable runnin
Adopt calculating opening control algorithm to calculate the best opening of electronic expansion valve according to the evaporating pressure, condensing pressure, compressor energy class, etc., which keeps the liquid level stable under various condition and ensures unit stable running.
Separating efficiency of oil separator is above 99.99%, which reduces the reliance on oil return and the liquid refrigerant quantity that come into compressor through ejector loop, avoids lowering the viscosity of the lubricating oil because of excessive liquid refrigerant which affects the service life of the :ompressor bearings, and keep the compressor long-term stable running.

Convenient operation and high intelligence
Convenient installation, just connect water pipe and power.
Large colored touch screen, free switch between manual control and automatic control. Adopt special microcomputer controller and high intellectualization.
