Text version of the page

General information & application Fincoil AHB are efficient and reliable air coolers suitable for cold and subzero rooms in refrigeration plants. Air coolers AHB have been designed for pumped system ammonia, but are also suitable for all other refrigerants that do not corrode steel. Air coolers AHBG have been designed for liquid circulation. Refrigerants Ammonia R-717, all H(C)FC, brine, CO2 Capacities (SC2) 1.8 up to 189 kW Air volume 2,160 up to 88,560 m3/h. Standard configuration • Finned coil hot dip galvanised steel A1 - Steel tubes ø 20 mm - Tube pitch 57.74 x 50 mm staggered - Fin spacings 8, 10, 12 or 15 mm. • 1-5 fans with low sound pressure level and four fan speed alternatives. Standard draw-through execution. Fan diameters Ø 350, 450, 500, 560, 630 and 710 mm. Standard power supply 400/50/3. Motors are equipped with bimetallic thermal contacts in the windings, connected to separate terminals in the box (note: fans Ø 350 mm without thermal protectors). Protection class IP54. • Fan sizes Ø 450, 500 and 560 mm available with four fan speed alternatives (700/900/1150/1400 rpm), fans Ø 350, 630 and 710 mm with two fan speeds (900/1400 rpm). • Casing material is hot dip galvanised steel. • Fully insulated hinged double drip tray. • Equipment for both ceiling and floor mounting is standard for all models. • Optimised circuiting design. Standard circuiting AHB is for R-717 pumped circulation. • Refrigerant connections on the right side, as seen from the coil side. • Stickers indicate refrigerant in/out. • A manual including installation and service instructions is shipped with each unit Design pressure Design pressure 24 barg, higher design pressures on request. Each heat exchanger is leak tested with dry air. Design pressure for brine coolers is 16 barg. AHB(G) Industrial air coolers FeZn AHB
