With the Guntner product calculator “mPc,” we are able to offer you
more than just an overview of prices or the complete product range.
this thermodynamic selection program enables you to calculate your
own tailored selections based on precise and actual thermodynamics
rather than factors or multipliers. a team of experts stand by to guide
you through the selection process.
the program can be updated via the internet ensuring that you always
have the most exact and precise information for proper selection.
We recommend using Guntner’s Product calculator for exact
thermodynamic calculations. Varying conditions such as refrigerants,
humidity levels and material combinations are all taken into account by
the software to most accurately select products to fit your specific needs.

the aGBK range provides a unique air distribution
pattern that offers the ultimate in worker comfort for
any type of processing room. extreme low noise fan
operation coupled with our superior technology sets
the benchmark for the industry. these features result
in less acoustic stress on staff, reduction in staff
absenteeism due to illness, and provide a pleasing
atmosphere which encourages work performance.
CASING: corrosion resistant aluminum (aImg3), sea-water resistant.
all casings are powder coated – color ral 9003
(signal White) and suitable for all stringent food
industry applications. construction detail takes
accessibility into account and does not allow for
“tight spots.” all parts are easily accessible for
service and cleaning purposes. fan orifices are
optimized by manufacturer to ensure maximum
efficiency, air throw and airflow. all fans are
individually compartmented within complete tube
sheets to allow for fan cycling for capacity control
and reduction of operating costs. all hangers and
fittings used for construction and assembly are
manufactured from stainless steel 304.
TRAY: trays come with insulated (air gap) pans to prevent condensation.
corrosion and sea-water resistant light weight
aluminum (aImg3) offered for all models. trays
are powder coated color ral 9003 (single White).
all trays are our unique “fold down” type and can
be either folded down or completely removed,

if required, for cleaning purposes. the “sloped
design” of the cooler ensures maximum and efficient
drainage during the defrost cycle. drain outlet
connection PVc 1 1/4”.
TUBE: tubing is manufactured from the highest quality 304 stainless steel in accordance with asme B31.5 1/2” (12mm) tubing.
staggered tube arrangements- 1.969” x .98” (50 x
25 mm) allows for maximum heat transfer efficiency.
tubes are mechanically expanded to ensure
mechanical bonding coupled with the best heat
transfer efficiency ratio from fin to tube.
all coils are pressure tested to 450 psig with dry air
under water, and shipped with a holding charge.
FINS: aluminum fins with a corrugated pattern provide enhanced air turbulence, guaranteeing contact with all surface areas within the coil bundle.
100% drawn die formed finned collars are standard
and result in accurate fin spacing of 6.3 and 3.6 fPI
(4mm and 7mm).
all fins are manufactured with a continuous fin sheet
in order to reduce the risk of frost build-up, air-side
pressure drops, dust, dirt and bacteria, and simplify
any cleaning procedure.
COIL CIRCUITING: each unit is specifically circuited to optimize coil performance and capacity with a low-pressure drop.
FANS & MOTORS: external rotor axial fans,
designed for low noise level operation are standard
for the entire range.
all motors are aluminum die cast and of the highest
efficiency, maintenance free, guarantee a long life
and have low noise levels.
all fan motor assemblies are of the blow-through
type.
fan guards are galvanized steel and PVc coated.
standard voltages include 230V and 460V for 60Hz
applications and 400V for 50Hz applications.
DEFROST: air or electric are standard options for all units. electric heater elements are stainless steel sheathed and fit directly into tubes within the coil bundle to provide for enhanced heat transfer during the defrost cycle. elements are held in place with clips to prevent them from moving during transport or operation.
ELECTRICAL: each fan motor is factory wired to the junction box with a single point connection. (factory installed jumpers can be removed for individual/capacity control.)
all heater wiring is terminated within a junction box
for quick and simple field connections.
DELIVERY & PACKING: all units are shipped crated, and in a position to facilitate installation.
