General information & application The Helpman THOR series is a wide and flexible range of heavy-duty industrial air coolers for both cooling and freezing applications in medium to large cold rooms. Suitable for a wide range of applications, with a special focus on meat storage, agricultural produce and packed products. 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 -40°C Refrigerants all H(C)FC, brine, CO2 Capacities (SC2) 5 up to 116 kW* Air volume 4,000 up to 67,000 m3/h. * Higher capacities on request Standard configuration • Finned coil - 7 coil block modules - 4, 6 or 8 tube rows deep - Cu tubing ø 5/8” - Tube pitch 50 x 50 mm square - Corrugated Alu-fins - Fin spacings 4, 6, 7, 8 and 10 mm. • 1-7 Fans, available in a range of different executions. Diameters Ø 406 mm up to Ø 710 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. • All models available in both blow-through (THOR-B) and draw-through (THOR-Z) execution. • Corrosion resistant casing material: Aluminium/Sendzimir, white epoxy coated (RAL 9003). • Hinged, enclosed end covers (modules 1 - 4). Larger modules fitted with easily removable 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. THOR Industrial air cooler THOR
