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.


CONSTRUCTION MATERIALS

• The entire casing, tube sheets and tray manufactured with either 304 or 316 stainless steel.

• Epoxy coated aluminum or stainless steel (304 or 316) fins.

• Units are supplied standard with carbon steel black pipe connections but can be ordered with either stainless steel pipe flanges (ansI B16.5) or carbon steel threaded connection (asme B1.20).

• Re-heat coils – separated from the cooling coil by means of an air gap.

• Extended pan at connection end.

• For unit operation below 35ºF room temperature – consult sales office.

DEFROST OPTIONS:

• For electric defrost – defrost termination and fan delay thermostat factory fitted.

• Heater limit thermostat fitted and pre-wired.

• Hot gas defrost in the coil.

Optional Features

ELECTRICAL

• No wiring.

• All motors wired to common/individual non-fused disconnect.

• All motors wired to common fused disconnect with thermal protection for each motor.

• All motors wired to fused disconnect with single starter and thermal protection for each motor.

• Various wiring options are available – please consult with factory for an alternative to suit your specific requirements.
