Text version of the page

General information & application Helpman TYR-A industrial air coolers have been designed for airsock application. All models are fitted with an airsock ring and fan motors capable of supplying the additional external pressure that is required for the proper functioning of an airsock system. Suitable for applications like processing rooms, working production area’s and greenhouse cooling. Evaporating temp. +5 to -15 °C Refrigerants ammonia (R-717), all H(C)FC, brine, CO2 Capacities (SC2) 4 up to 41 kW* Airsock diameter 450 up to 730 mm * Higher capacities on request Standard configuration • Finned coil - 4 coil block modules - 4 or 6 tube rows deep - Stainless steel tubing ø 16 mm - Tube pitch 50 x 50 mm square - Corrugated Alu-fins - Fin spacings 4, 6 and 7 mm. • 1-3 Fans, available in a range of different executions. Airsock diameters Ø 450 up to Ø 730 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.
