General information & application
Helpman TYR-A industrial air coolers have been designed
for airsock application. All models are fitted with an airsock
ring and fan motors capable of supplying the additional
external pressure that is required for the proper functioning of
an airsock system. Suitable for applications like processing
rooms, working production area’s and greenhouse cooling.

Refrigerants ammonia (R-717), all H(C)FC, brine, CO2
Capacities (SC2) 4 up to 41 kW*
Airsock diameter 450 up to 730 mm
* Higher capacities on request
