There are three types of cooling water systems: once-through, open recirculating, and closed recirculating or closed loops. Closed recirculating systems use heat exchangers and circulate water in a closed loop with negligible evaporation to the atmosphere. Heat is transferred to the closed cooling water loop by heat exchange equipment and removed from the closed system loop by a second exchange of heat.

Biochemica offers a complement of products for treating the water within closed loop cooling applications as well as pre commission cleaning services. More details on Biochemica’s pre commission cleaning works are coming soon, please Contact us for further information.
