Self-supporting galvanized steel frame protected with polyester powder painting. Panels are easily removable for maintenance and service activities.
Hermetic “scroll” type with overload protection by a klixon and complete with oil sight glass and crankcase heater. They are installed on vibrations absorbing rubber and placed within a close compartment to reduce sound level and to allow service and maintenance activities while unit is in operation.
Braze welded plate type with two independent refrigerant circuits and one water circuit. The circuit is made to guarantee an homogeneous cooling of all the water flow even during partial load. The insulation is made of flexible closed-cells lining. As protection, a flow switch is recommended to mount to stop the unit in case of no water circulation.
