Catalog
(*1)There may be a case where the temperature performance cannot be maintained due to environmental temperature, heat load, circulation pipe distance, etc. (*2)Capacity when the cooling water temperature below +25℃.
(*3)Capacity when using tap water. Flow rate when the discharge pressure of CHW-900 is at 0.12 MPa and of CHW-1500/2200 at 0.3 MPa.
(*4)Capacity varies with the water temperature. Please note it may cause a defect if the flow rate does not increase at high temperature, so please confirm if the required flow rate is secured in advance.
•Power cable is not included.
•Standard products cannot use pure water as circulating fluid.
•Please ask us when mixing chemicals for water treatment to circulating fluid.
•The fee for Delivery and Installing are quoted separately.
★Can upgrade the abilities and add some functions by selecting the following options.
1) To improve accuracy of temperature adjustment (Heater added)
2) To improve capacity of pump unit (changes to Large flow rate / High head; Several types)
3) To add safety devices (No-fuse breaker and Earth leakage breaker)
4) To change materials such as the stainless steel wetted parts, the circulating fluid piping for the antifreeze, and the ball tap.
5) Additional functions (Special order/Option: Remote control box, To reduce noise by fan speed controller)
6) Other (Device fixing brackets).
