Helpman THOR-F Alfa Laval

The Helpman THOR-F air cooler series has been specifically designed for the refrigerated storage of agricultural produce. These coolers are characterised by an optimized capacity/air volume ratio and a relatively low profile. All models have been optimized for air temperatures around 0°C and a small temperature difference to avoid produce dehydration.
