AMK(G) - Dual discharge industrial air coolers FeZn - Alfa Laval - #1

Text version of the page

General information & application Fincoil AMK air coolers are designed for cooling of cold and subzero storages where a low profile dual discharge cooler design is required. AMK air coolers are also suitable for cooling of industrial working areas. Air coolers AMK have been designed for pumped system ammonia, but are also suitable for all other refrigerants that do not corrode steel. Air coolers AMKG have been designed for liquid circulation. Refrigerants Ammonia R-717, all H(C)FC, CO2, brine (G) Capacities (SC2) 1.6 up to 106 kW Air volume 2,160 up to 48,600 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 4.5, 6, 8, 10, 12 or 15 mm. • 1-4 Fans with low sound pressure level and four fan speed alternatives. Standard blow-through execution. Fan diameters Ø 450, 500 and 630 mm. Standard power supply 400/50/3. Motors are equipped with bimetallic thermal contacts in the windings, connected to separate terminals in the box. Protection class IP54. • Fan sizes Ø 450 & 500 available with four fan speed alternatives (700/900/1150/1400 rpm), fans Ø 630 with two fan speeds (900/1400 rpm). • Casing material is hot dip galvanised steel. • Fully insulated double driptrays. Easy to open and remove. • Optimised circuiting design. Standard circuiting AMK is for R-717 pumped circulation. • 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. AMK(G) Dual discharge industrial air coolers FeZn AMK
