STANDARD FEATURES

The CDH air conditioners are designed for the thermoregulation of automation panels and electrical shelters in general. Are suitable for installation in the most harsh environment of the industry as moving cranes, bulky material handling lines and in all application where present
high dusty or corrosive atmosphere, high vibration or extreme temperature.

Thanks to Refrind’s experience, CDH air conditioners result in reliable, sturdy, easy and reduced in maintenance products, therefore suitable for operation in particularly harsh conditions.
