Forced Draft (SVC Series) – Evaporative Condensers

Forced draft evaporative condensers (SVC series) is the design of the blast, centrifugal fan mounted on the bottom of the device integrated with the water tray, the use of the belt drive system case of this series of evaporative cold noise is less, suitable for indoor installation of the occasion. This series of evaporative cooling can also be container transport. SVC Series evaporative cooling is also very easy to maintain, both sides of the fan shell plate can be removed, it is easy to access the entire belt drive system.

Forced draft evaporative condensers (VC/SVC series) are executed on principle of forced air flow. With 10 different models according to capacity covering an extremely wide range of application according to required capacities in different ambient conditions. Condensers are generally used for R717(ammonia) but also suitable for refrigerants like R404, R134a, R507a etc.
