ATDC

overview

Overview
ATDC is a combined fan unit heater/cooler and is designed for heating and cooling industrial, manufacturing, retail, and warehouse premises, as well as garages, supermarkets, and the like.

Hydrophilic Fins
ATDC features a corrosion-proof cooling/heating coil of hydrophilic fins and copper tubes. The hydrophilic fins feature a hygroscopic design to enable a significantly higher airflow speed over the coil’s surface compared to aluminum. The hydrophilic fins also boast better corrosion resistance compared with aluminum fins.

Openable Casing
The ATDC unit cooler/heater features a white lacquered sheet metal or EN 1.4301 stainless steel casing. The casing can be opened for interior cleaning. The roof and base are easily removed with just two screws. The water and steam pipe connections are located on the unit’s side. The motor, impeller, and protective grille are designed as a compact and composite unit.
