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.

Casing: The casing is corrosion resistant Aluminum (AIMg3) and seawater resistant up to fan diameter 20” (500 mm). from fan diameter 26” (650 mm) and larger, the casing is treated and painted corrosion resistant galvanized steel.

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 the manufacturer to ensure maximum efficiency, air throw and airflow. All fans are individually compartmented within complete tube sheets.

All hangers and fittings used for construction and assembly are manufactured from stainless steel 304. products have easily removable side panels for access to internal and electrical components.

Tray: All models have corrosion resistant light weight Aluminum (AlMg3) and are seawater resistant.

Trays are powder coated color rAl 9003 (signal white). All trays are our unique “fold down” type and can be either folded down or completely removed, if required, for for cleaning purposes. The “sloped design” of the tray ensures maximum and efficient drainage during defrost cycle. Drain outlet connection can be either 2 x 1 1/4” NpT or 2 x 3/4” NpT.

Standard Features of Construction

www.guntnerus.com …keep(s) your quality. 309.09 3

Tube: All tubing, headers and connections are manufactured from the highest quality 304 stainless steel 5/8” (15mm) tubing.

parallel, “in-line,” 1.969” x 1.969” (50 x 50mm) allows the reduced air-side pressure to drop through the coil. Tubes are mechanically expanded to ensure mechanical bonding coupled with the best heat transfer efficiency ratio from fin to tube.

our proven “floating coil” with support tubes does not permit the refrigerant carrying tubes to come into contact with the tube/end plates, and eliminates the risk of tube failure at the tube end plates. 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 spacings of 6.3, 3.6 and 2.5 fpI (4, 7 and 10 mm).

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 - simplifying any cleaning procedure.

Coil CirCuiTing: each unit is specifically circuited to optimize coil performance and capacity with a low pressure drop (consult with selection software to obtain best circuiting for each application). horizontal headers are standard for re-circulated and flooded applications. coil connections are manufactured from 304 stainless steel in accordance with AsMe b31.5 requirements.

Fans & MoTors: external rotor axial fans are standard for the entire range.

Internal motor thermo contacts must be incorporated into the control circuit for motor protection.

All motors are aluminum die cast and of the highest efficiency. They are also maintenance free with guaranteed long life and low noise levels.

fan guards are galvanized steel and pVc coated. All motors are of the blow through type.

standard voltages are 230V and 460V for 3~ / 60hz applications and 400V for 3~ / 50hz applications.

DeFrosT: standard defrost options for all units include air, electric or hot gas.

electric heater elements are stainless steel sheathed and fit directly into tubes within the coil bundle to provide enhanced heat transfer during the defrost cycle.

elements are held in place with clips to prevent them from moving during transport or operation.

eleCTriCal: All fan motors are factory wired to the junction box with single point connection. however, 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. when heater circuit amperages exceed 48 amps, multiple circuits are provided in order to comply with the Nec limitation of 48 amps per circuit.

Delivery & PaCking: All units are crated and shipped in a position to help facilitate installation.
