Electronic controls are susceptible to troubles when the temperature is too high. They are cooled frequently by the blow in method with air from the atmosphere and/or by some indirect air/ air heat exchangers without filters. The functioning of those units depends, however always on the ambient temperature. The cooling effects are, therefore often unsatisfactory in the warm season. The cooler of the switch cabinet has been developed in line with more than 20 years of experience in refrigeration engineering and thousands of industrial cooling plants built for any application . The cooling unit SK built is ready for connection. You just have to prepare two opening in the switch cabinet. Capacities available up to 600 to 4500 Kcal/h.
