Water Cooled Centrifugal Chiller
Model: KWL | Refrigeration Capacity: 1760~10548kW | Refrigerant: R134a
01
Two-Stage Compression / Broader Range & Higher Efficiency
Dual-stage compression improves compression ratio and broadens operating range, providing larger pressure ratio and higher efficiency. Reduces surge risk under low load, enabling safe and stable operation across all conditions.
02
Efficient & Energy-Saving / Over 6% Efficiency Gain
Combining two-stage compression with jet enthalpy enhancement technology, system efficiency is improved by over 6%. Features efficient economizer, high-efficiency falling film evaporator and two-stage throttling, fully meeting national energy efficiency standards and significantly reducing operating costs.
03
Built-in Oil Pump Design / Zero Energy Loss Oil Return
Unique injection and oil return technology promptly injects lubricating oil back into the oil tank, completing low-pressure side oil return without energy loss. Prevents decreased heat exchange efficiency caused by oil entering the refrigerant system.
04
Flash Economizer / Enhanced System Efficiency
Built-in flash economizer device separates medium-pressure saturated refrigerant for gas-liquid separation, improving overall system operation energy efficiency and optimizing thermal performance.
05
Quiet Operation / Ideal for Noise-Sensitive Environments
Optimal speed and impeller diameter configuration reduces operating noise. Two-stage compression lowers speed, especially achieving low noise in high-frequency regions. Reasonable vibration reduction makes the unit ideal for schools, hospitals and office buildings.
06
Low Carbon & Eco-Friendly / R134a Ozone-Safe Refrigerant
Uses R134a environmentally friendly refrigerant containing no chlorine with zero destructive effect on the atmospheric ozone layer. Currently the best choice for large chiller refrigerants, aligning with global sustainability goals.
