How to choose a water Chiller for injection molding machine



The vertical and horizontal injection molding machine working under normal ambient temperature, the condensing temperature is below 35℃ for water cooled Chiller, the condensing temperature is below 45℃ for air cooled Chiller.


A: First way of choosing Water Chiller

1HP water cooled Chiller is suitable to 80 tons injection molding machine, chilled water temperature range 5-10℃.
1HP water cooled chiller is suitable to 100 tons injection molding machine, chilled water temperature range 10-15℃.
1HP water cooled chiller is suitable to 120 tons injection molding machine, chilled water temperature range 15-20℃.
Normally, when choose Water Chiller Machine, we suggest selectivity coefficient 0.8,
i.e. 1HP water cooled chiller is suitable to 80x0.8=64 tons injection molding machine, chilled water temperature range 5-10℃.


B: Second way of choosing water chiller

1HP water cooled chiller is suitable to injection molding machine with shot weight 10QZ, chilled water temperature range 5-10℃.
Shot weight 1QZ=28.5g


C:1HP water cooled chiller need a 1.2 tons cooling tower to remove the condenser heat.
