FES – AIR COOLERS
Features and applications
FES model ceiling type coolers are specially designed for small, medium and large industrial cold room, frozen storage blast freezing and rapid cooling room application.
Fritem FES series are ceiling mounted, single side discharge evaporators draws air across the coil
Unit coolers with three phase motors are available for an operation with two rotation speed and high speed provides a rapid pre-cooling and then slower air circulation which avoids humidity loss.
