Descripción

The Helpman TYR-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 produce dehydration. Standard configuration
  • Coil - 2 coil block modules - 6 tube rows deep - Stainless steel tubing o 16 mm - Tube pitch 50 x 50 mm square - Corrugated Alu-fins - Fin spacing 7 mm
  • 3-7 Fans, blowing through the coil. Diameters O 406 mm or O 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.
  • 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 schrader valve on the suction connection for testing purposes.
  • Sufficient room for fitting the expansion valve inside casing.
  • Suitable for dry expansion or pumped system.
  • Delivery in mounting position. Coolers are mounted on wooden beams. Installation can take place with use of a forklift.

Technical documentation How it works Alfa Laval finned coil air heat exchangers have been designed to achieve an optimized exchange of thermal energy between air and a refrigerant or fluid. The heart of our air heat exchangers is the finned coil, built up from a circuit of interconnected tube serpentines and fins to increase the heat exchanging surface. Thanks to the combination of key design variables (coil materials, coil geometry, casing design, fan type), air units are very versatile heat exchangers with a great variety of applications in many industries. Alfa Laval supplies finned coil air heat exchanger products for a wide variety of applications. Air coolers & air-cooled condensers Air coolers and air-cooled condensers are key components in air cooling and air conditioning systems. On the refrigerant side the most common media are a brine or an evaporating refrigerant like H(C)FC, ammonia or CO2. A chilled brine may be supplied from a chiller that is potentially located far away, but a liquified refrigerant must come from a nearby condensing unit. When an evaporating refrigerant is used, the cooling coil is the evaporator in the vapour-compression refrigeration cycle (direct expansion or DX system). ''
