Chilled Water Solution
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.
ARTECH offers a full line of products for closed loop cooling applications designed to maintain clean heat transfer surfaces. There are three main facets concerning the treatment of closed recirculating system.
(Hot water heating, chilled water systems)
- Corrosion
- Biological Control
- Energy Efficiency
