This is a Screw Heating Cooling Chiller designed for chemical reactions and pharmaceutical production. SHANGHAI SOOUNEY REFRIGERATION EQUIPMENT CO., LTD manufactures this product. The available models are SA-50SX and SA-65SX.
The SA-50SX has a nominal cooling capacity of 48.9 kW, with a total unit power input of 28.3 kW. The SA-65SX provides 66.9 kW of cooling capacity and a power input of 37.3 kW. Both units use a 380V/3N/50Hz power supply and start using Y-Δ (star-delta) starting mode.
As a result, this Screw Heating Cooling Chiller delivers stable high and low temperature control for demanding industrial applications.
The compressor is a 5:6 asymmetric semi-hermetic twin-screw type. The evaporator is a high-efficiency shell-and-dry (dry-type) design. The condenser uses copper tubes and aluminum fins.
The SA-50SX is equipped with 6 condenser fans, each rated at 0.6 kW. The SA-65SX has 8 condenser fans with the same 0.6 kW rating per fan.
The refrigerant charge is R134A, with 10.9 kg for the SA-50SX and 14.8 kg for the SA-65SX. The evaporator water flow rates are 9.1 m³/h and 12.4 m³/h, respectively. The pressure drops are 45.3 kPa and 41.5 kPa. The pipe connection size is DN65 for both models.
This system operates reliably over long periods, offering energy efficiency and stable performance.
The unit is equipped with a fully automatic PLC control system. The capacity can be adjusted in four steps: 0%, 33%, 66%, and 100%.
The dimensions of the SA-50SX are 2500 × 1925 mm, while the SA-65SX measures 2950 × 2050 mm. The dry weight is 1900 kg and 2000 kg, respectively. The operating weight is 2200 kg and 2300 kg.
Therefore, this Screw Heating Cooling Chiller is easy to install in industrial facilities. It is also a strong choice for wholesale buyers, and OEM/ODM services are available.
