General information & application The Helpman LFX 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) 7 up to 29 kW Air volume 5,100 up to 22,400 m3/h Standard configuration • Finned coil - 2 coil block modules - 6 tube rows deep - Cu tubing ø 1/2” - Tube pitch 38 x 38 mm square - Aluminium fins - Fin spacings 7 mm. • 3-8 Fans, blowing through the coil. Diameters Ø 305 mm or Ø 356 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. • Corrosion resistant casing material: Aluminium/Sendzimir, white epoxy coated (RAL 9003). • Hinged (module 1) or easily removable (module 2) end covers. • Easily removable driptray, horizontal drain(s) G 1”ext. • 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.
