General information & application
The Helpman LFX air cooler series has been specifically
designed for the refrigerated storage of agricultural produce.
These coolers are characterised by an optimised capacity/
air volume ratio and a relatively low profile. All models have
been optimised for air temperatures around 0 °C and a small
temperature difference to avoid product dehydration.
Evaporating temp. +5 to -10 °C
Refrigerants all H(C)FC, brine, CO2
Capacities (SC2) 7 up to 29 kW
Air volume 5,100 up to 22,400 m3/h
Standard configuration
