20. Options
20.1 ELECTRICAL REHEAT (only for CVC14/20/28/41) - RSC
is supplied when a warming of room air is required.
The heating control can be incorporated in the unit by a thermostatic device, possibly with
a contactor; or directly from the outside of the cooling unit by the customer's system.
The heating element is positioned protruding from the cooling unit in front of the air outlet.
20.2 EMERGENCY VENTILATION EVAPORATOR FAN - EVDC24/EVDC48
With this option, evaporator fan is supplied with 24 or 48 VDC. DC evaporator fan must be
directly fed by the back-up battery, which is part of power supply system provided by the
client. DC emergency fans are not provided with a free-cooling system. Therefore, in case
of power supply shortage, they are useful only to recirculate air inside the cabinet.
20.3 PROTECTIVE TREATMENT ON CONDENSER COIL - PCC
Epoxy treatment on condenser coil surfaces to protect it against corrosion. This treatment
reduces condenser coil efficiency. Therefore, also cooling capacity of the unit is reduced.
