To give you our best offer one time,please indicate:
1.What is the cooling capacity you need?
2.Air cooled or water cooled?As you see,water cooled need a separated cooling tower .
3.What is the outlet water/glycol/seawater temp you need?
4.What is the power supply?
5.Do you need water pump,water tank together?
6.Is there any special requirement for the refrigerant?R22,R134A,R407C,R404A or other?
