CS, LS, ECS
High-performance industrial air coolers designed for cold rooms.
HFC – NH3 – Brine – CO2
CS models feature internally grooved tubes and staggered rows, making them suitable for both positive and negative temperature applications.
LS models, equipped with internally grooved tubes and in-line rows, have a high ratio of secondary fin surface to primary tube surface. They are ideal for high humidity cold room and freezing application.
ECS models are optimized for medium and low temperature CO2 application.

HFC – NH3 – Brine – CO2
-
Capacity range:
6.7 up to 261.7 kW
-
Air quantity:
3,900 up to 94,000 m3/h
