THOR-A - Industrial airsock air cooler0 pages

General information & application
Helpman THOR-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.
All THOR models have been highly standardised in
construction and dimensions, while maintaining flexibility in
fin spacings, coil construction and circuiting design.
Evaporating temp. +5 to -15 °C
Refrigerants all H(C)FC, brine, CO2
Capacities (SC2) 4 up to 41 kW*
Airsock diameter 450 up to 730 mm
* Higher capacities on request
Standard configuration
• Finned coil

Aluminium/Sendzimir, white epoxy coated (RAL 9003).
• Hinged, enclosed end covers.
• Hinged driptray, drain(s) 32 mm
PVC connection, freely adjustable into either horizontal or
vertical position.
• Refrigerant distribution optimised to refrigerant applied.
• Refrigerant connections on right hand side
(fan side view).
• Fitted with schräder valve on the suction connection for
testing purposes.
• Sufficient room for fitting the expansion valve inside.
• Suitable for dry expansion or pumped system.
• Stickers indicate fan direction and refrigerant in/out.
• Delivery in mounting position. Coolers are mounted on
wooden beams. Installation can take place with use of a
forklift.
Test
Design pressure 33 bar, higher design pressures on request.
Each heat exchanger is leak tested with dry air and finally
supplied with a nitrogen pre-charge. Brine coolers are tested
at 6 bar.
