Closed Circuit Coolers

New standards enhance efficiency


Closed Circuit Coolers are designed according to customers' requirements and assure exact compliance with their performance specifications. Our finned systems enhance heat exchange to the tube system and allow low material usage without performance loss. Tooling flexibility allows each system to be adjusted with its tube banks side by side or on top of each other, offers options of meeting extreme customer demands. Our many offical approvals and certifications allow us to design and manufacture closed circuit coolers for many and various applications.
