General information & application Industrial shock coolers Helpman THOR-T have been specifically designed for application in cooling and freezing tunnels. Shock-cooling is a process by which a product, mostly meat, is cooled quickly but not too deeply. The principle of shock-cooling is that the surface of the meat product is cooled until just below the freezing point, so that the surface becomes vapour-tight. This has the purpose of limiting the weight (moisture) loss of the product to a minimum. The product may not be cooled too deeply however, since otherwise the structure of the underlying tissue is damaged, resulting in a decline of the quality of the meat. For shock-coolers, it is important that the total surface of the product that is to be cooled be fully exposed to the cold air flowing from the cooler. For this reason, all models are characterised by an elevated external pressure (120 Pa). Evaporating temp. +5 to -40 °C Refrigerants ammonia (R-717), all H(C)FC, brine, CO2 Capacities (SC2) 11 up to 114 kW* Air volume 11,800 up to 66,400 m3/h. * Higher capacities on request Standard configuration • Finned coil - 2 coil block modules - 4, 6 or 8 tube rows deep - Stainless steel tubing ø 16 mm - Tube pitch 50 x 50 mm square - Corrugated Alu-fins - Fin spacings 7 or 10 mm. • 2, 4, 6 or 8 Fans, blowing through the coil. Diameters Ø 508 mm or Ø 560 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 (120 Pa). • Corrosion resistant casing material: 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. (not for R-717). • 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. TYR-T Industrial shock cooler TYR-T
