Closed Circuit Cooling Towers
Efficient Closed Circiut Cooling Towers
Erivac is proud to represent the Cofinair Group (Decsa, Gohl-KTK, and Jacir), a leading supplier of cooling towers, adiabatic coolers, refrigerant coolers, refrigerant condensers and adiabatic condensers providing cooling solutions and technology to businesses in various industries. With decades of experience and a commitment to innovation and quality, they have established themselves as a reliable partner for companies seeking efficient and dependable cooling solutions.
How does Closed Circuit Cooling Towers work?
Closed circuit cooling towers are cooling units used primarily for industrial or HVAC applications that, by taking advantage of a mass of cold air, allow process water to be cooled and excess heat to be dissipated. As closed systems, the process water to be cooled remains within the circuit and thus is not polluted by contamination or external agents. Unlike open cooling towers, therefore, in closed-circuit cooling towers the water, remaining inside the heat exchanger, remains isolated from the external environment, clean and free from any contamination that would otherwise damage or contaminate the process components.
Decsa has a wide range of models of closed circuit cooling towers: the REF-A series, equipped with axial fans, and the REF-C series, equipped with centrifugal fans. For both types, Decsa enhances the evaporation of water within the plants by using high efficiency “full surface” HDGS heat exchange coils and optimizing the L/G ratio at best.
Reliability and quality are also guaranteed by the UNI EN ISO 9001 certification, and by the use of coils heat exchangers designed with top-quality EN ISO 12305-3 grade E235 electro-welded tubes and subject to stringent quality control. The coils are also built to the Decsa standard that guarantees pressure tightness up to 25 bar and use at operating pressures up to 7 bar.
Decsa closed circuit cooling towers ensure excellent performance with low operating and transportation costs. These cooling systems, available in a wide choice of sizes and models according to the specific needs of each customer, are designed to ensure quietness and reliability and are used for all types of applications in industrial process cooling and HVAC systems.
Main areas of application are: – Food; – Automotive; – Chemical and Pharmaceutical; – Civil; – Commercial; – Metallurgical; – Hospitals, – Energy production.
Closed circuit cooling towers REF-C
Cooling tower with centrifugal fans
The REF-C series cooling tower at closed-circuit features a high-strength structure and paneling and is equipped with double-intake centrifugal fans, designed to ensure minimal noise. Designed to ensure low operating costs and low accessory costs, the cooling tower REF-C is particularly suitable for installations in the industrial or HVAC fields where quietness, efficiency and reliability are a key consideration in equipment selection.
Closed circuit cooling towers REF-A
Cooling tower with axial fans
The REF-A industrial cooling tower is made of Z-725 hot-dip galvanized steel sheet and is equipped with the latest generation of axial fans with balanced impeller, equipped with adjustable blades with high-efficiency profile. It is extremely flexible and particularly suitable for applications in cooling systems in the food, automotive, power generation, air conditioning, chemical, metallurgical and industrial fields. This cooling tower guarantees high-efficiency thermodynamic performance, cost savings and environmental sustainability.
