Altret Industries Pvt. Ltd.
Cooling Water Treatment Chemicals
The programs of ALTRET Cooling Water Treatments are intended to meet all the needs of cooling water systems. They are designed to face all kinds of challenges, which may occur.

Generally, these main problems have to be solved:
These problems cannot be considered separately, since they are inter-dependent. Therefore, a complete treatment is needed, based on the combination of different treatments.
