AHB(G) - Industrial air coolers FeZn0 pages
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).

• 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
