Note:

1, the table refrigeration conditions: chilled glycol water inlet temperature -25 ℃, water outlet temperature -30 ℃, the cooling water temperature 30 ℃, water temperature 35 ℃;

2, this series of units used in low temperature conditions, to use 55% of the glycol for antifreeze coolants;

3, the series unit uses imported from Europe hermetic compressors, superior performance, strong anti-strike capability liquid;

4, standard power supply: 380V / 3N-50HZ, voltage fluctuation allowed ± 5%, frequency fluctuation ± 2%;

5, host the actual head of the pump head minus head losses within the host. (1mH2O = 9.8KPa)

6, In addition to the specifications and requirements, we can provide non-standard products according to customer requirements.

Application:
Our water cooled screw chillers, water cooled screw type low temperature unit, flooded type water hillers, air-cooled screw chiller, air-cooled, water-cooled box type chillers products have been widely used in chemical industry, chemical fiber, plastics, oil, food, as long as the industry, printing, electroplating, electronics and other industries

Recommend products:
Usually cooling tower offers chilled water to water cooled chiller, here we recommend our dry cooler to instead of cooling tower.
