THOR-F - Agricultural storage cooler 0 pages
General information & application
The Helpman THOR-F 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) 18 up to 52 kW*
Air volume 12,800 up to 36,000 m3/h
* Higher capacities on request
Standard configuration
• Finned coil
- 2 coil block modules
- 6 tube rows deep
- Cu tubing ø 5/8”
- Tube pitch 50 x 50 mm square
- Corrugated Alu-fins
- Fin spacings 7 mm.
• 3-7 Fans, blowing through the coil. Diameters Ø 406 mm
or Ø 457 mm. Enclosed design spray-tight fan motors,
protection class IP55. Motors are equipped with a thermal
safety device in the windings, connected to separate terminals
in the box.
• Fans with elevated external pressure to ensure optimised
air distribution.

• 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.
