Ceiling Air Coolers
Ceiling-mounted air coolers for cold storage — electric defrost options, fin spacings for medium and low temperature duty.
About this equipment
Ceiling air coolers (unit coolers) hang in the cold room and circulate air across the product. ACC supplies ranges covering medium-high, medium and low storage temperatures, typically with electric defrost, internally enhanced copper tubes and corrosion-resistant housings.
Model families span roughly 1.4–35 kW class capacities depending on fin pitch and fan count (examples: 4.5 mm / 6 mm / 9 mm fin spacing). Motors are low-temperature external-rotor types (IP55, class F) with stainless defrost heaters in the coil and drain pan where specified.
Design highlights
Temperature bands
