SANHER have a vast experience with low-temp chillers for every process need. Whether you need -50ºC or -5ºC, we are here to help you complete that task. We will take the time to understand your process and operating condition before making an equipment selection.SHDL series screw type low temperature chiller is developed, designed and manufactured by SANHER. According to the temperature of chilled water(Ethylene glycol) , it is divided into seven types: high temperature type, medium temperature type, quarter low temperature type, sub-low temperature type, low temperature type, deep low temperature type and ultra low temperature type. Each type has 32 standard specifications . The cooling range is from 99KW to 462KW, and the temperature range of the chilled aqueous solution is -50°C to 0°C. The unit is suitable for refrigeration, food processing, quick freezing, industrial cooling ,etc.

1.High efficiency and energy saving:
- The unit adopts high efficiency twin-screw compressor ,runs efficiently under full load and partial load.
- Patented screw rotor design to increase compressor speed.
- The heat exchanger adopts a new high-efficiency heat transfer tube and counter flow design to enhance the heat transfer efficiency on the water side and the refrigerant side ,improve efficiency.
The unit can intelligent control according to load demand: 100%, 75%, 50%, 25% (or start), 0, saving energy.
The total number of the screw compressor parts is only 1/10 of the conventional compressor. Simple structure, few wearing parts , there are no inlet and exhaust valves, the humidity is not sensitive, the failure rate is extremely low, the screw compressor can run for 40,000 hours without trouble. .
3. Reliable operation
- The unit has 7 kinds of safety protection measures to ensure the normal operation.
- The unit is designed for dual-circuit and dual-compressor. When one compressor fails, the other compressor can still operate normally without affecting the customer's use.
- All units are tested by the safety inspection system before leaving the factory to ensure the performance.
- The unit is filled with refrigerant and lubricating oil before leaving the factory. The customer only needs to connect the inlet and outlet pipes and the power supply to run.
- The unit adopts the microcomputer control system, the interface can displays the fault content directly, which is convenient to know the fault in time and elimination.
We can manufacture non-standard units according to different power supply systems in different countries, also we can customize screw-type integrated units, anti-corrosion units, explosion-proof units and other special units according to user requirements.
A variety of refrigerant options:22, R407C, R134a ,etc.
