How To Use Model Code Index:

Example –Assume a performance of 2,000,000 BTU/Hr and 20,000 CFM at 0” Ext. S.P. at standard conditions, with filters is required. Reading the Rating Table on Page 14, we find a Series SMP Steam Make-Up Air Propeller Fan Assembly with a 44” fan at the required performance. The model code can be constructed as follows:

Type is Production (code A), Series is SMP, Size is 44, Number of blades is 3, Blade code is L. The fan is made of steel (code ST) with a totally enclosed fan cooled motor (code FC), motor HP is 3 (code K) and RPM/Voltage is 1750/460/60/3 (code 3).

Notes: * 3 = Drive arrangement for DWDI or FC, belt drive centrifugal fans, AMCA standard 99-2404-78 – = Close couple belt drive, propeller fans

** 1 = Centrifugal fan, Class I, per AMCA standard 99-2408-69, product definitions varies = Propeller fan – number of blade for propeller *** Airflow delivery in thousands @ standard density (0.075 lbs/ft3)

**** ST = Steel GL = Galvanized Steel GN = Galvannealed Steel

All other informational fields must be filled with hyphens/dashes (–) if they are not applicable to the fan being considered.

Function

Air removed by exhaust systems must be replaced system-atically by outside air. If this is not done, the exhaust system, while in operation, creates a negative pressure inside the building. The negative pressure conditions created reduce the overall effectiveness of the exhaust and ventilating systems of the entire plant. Smoke, fumes or corrosive vapors from manufacturing processes will build up, making personnel uncomfortable and reducing their efficiency.In the winter months, make-up air provides a dual function of supplying tempered outside air for heating as well as air to balance the system. If a negative pressure exists, hot and cold spots are likely to develop since airflow is not uniform through-out the building. Workers near windows and other openings are subject to cold drafts. The infiltration of cold air overloads the existing heating system in the winter, thus reducing its efficiency.The installation of a heated make-up air system will eliminate these negative pressure problems in the plant. Both the central heating system and the exhaust or ventilating system will be restored to full operating efficiency.

Advantages of make-up air in your plant:1. Worker comfort and efficiency increase because dust, fumes and contaminants can be removed efficiently by the existing exhaust systems.2. Bothersome drafts and cold spots are eliminated.3. Stacks on ovens, boilers and other direct or indirect fired equipment are restored to full efficiency.4. Overloaded plant heating systems are returned to normal operation.5. Water condensation problems are reduced or eliminated.6. Low initial equipment cost (assuming boiler capacity is already available) on steam units.7. No elaborate safety controls resulting in few nuisance shutdowns.

8. Simple control system and therefore electrical maintenance is simplified.9. Minimal safety hazards.

A Single Package AssemblyGasThe Hartzell gas fired units produce very low levels of CO and are easy to maintain. Base unit consists of fan and burner sections. Many optonal features are available.

SteamThe Hartzell steam make-up air unit is a “single package” assembly. The standard unit includes fan, housing, steam coil, and shutter, pre-wired except for the steam valve. (Plumbing and valve wiring are supplied by the customer at the job site.)The standard control package provides for constant discharge air temperature, and low temperature shutdown to protect against coil freeze-up.

steel. The basic unit consists of a fan and burner section, NEMA 4/12 control cabinet, plumbing, burner/recirculating air section and inlet bird screen. Both the electrical control cabinet and plumbing are mounted externally. Roofs are peaked to resist water penetration and collection. On sizes 15,000 CFM through 60,000 CFM, units have a standing seam roof. Standard mount-ing position for control cabinets and plumbing is on the right hand side of the unit. The access door will be opposite the con-trol cabinet (left hand side). Standard right hand control position is determined by facing into the airstream. Left hand controls are optional. Lifting lugs are standard on all units.

• The air recirculation feature on Model GFR is designed to pro-vide continuous building air make up, pressurization, and heat-ing with maximum efficiency. These self-contained units are fully factory wired, plumbed, assembled and tested. They aredesigned to provide control of the make up air volume, via building pressure, or manually adjusted potentiometer located on the remote station. Units are direct fired, designed to burn either natural gas or propane with 20% to 100% fresh air intake and 0% to 80% recirculated air. This allows recirculation of clean plant air when heating, pressurization requirements and exhaust loads are at minimum levels. Motorized recirculation and profile plate dampers are standard.

• Remote stations with “Fan,” “Off,” and “Heat” selector switch and recirc control is standard.

• Fan motors mounted in the airstream as standard. Drives are fixed pitch type with belts that are oil, heat, and static resistant. Relubricable pillow block bearings are standard, with a minimum L10 life of 30,000 hours.

• Burners are Maxon Type “NP-LE” with a maximum 25:1 turn down ratio with natural gas or 20:1 turndown ratio with propane gas.

• The standard temperature control system is Maxitrol Series 14, which controls the discharge duct temperature. Standard units can develop a maximum discharge temperature of 90°F.

Basic Operation and ControlsHartzell Model GFR Direct Gas Fired Forward Curved Make-Up Air Heaters with Air Recirculation Features are provided with a control system as standard. This system includes the master control panel mounted in a NEMA 4/12 enclosure.

Recirculating Unit Controls

Manual OperationDuring down-time recirculating shutters are closed. Upon start-up, Recirc Shutter moves to whatever position the “Return Air” controller is set, up to 80% recirc air. The Shutter at the Burner moves conversely to the above Recirc Shutter, maintaining proper velocity across the burner.

Automatic OperationAutomatic modulation for face- and Recirc Dampers. Dampers are modulated based on internal building pressure. Set point can be adjusted on controller at remote station.

If a pressure signal is supplied, a controller reads the signal and compares it to the controller setpoint.

The controller then provides an output signal to the damper actuators to modulate the return air and burner (outside air) dampers. This maintains proper airflow velocity across the burner.

OFF

Winter

Set selector to “SUMMER” for untempered air; to “WINTER” for heated air.

Airflow switch does not permit burner to ignite if airflow is inadequate.

High-temperature limit shuts unit off if discharge temperature rises over 140°F set point.

Combination high-and-low gas pres-sure switch shuts off burner if pressure fluctuates excessively.

Flame Safeguard monitors normal start-up. Closes main gas valve instantly upon flame failure.

Automatic gas shut-off valve opens after all safety devices are satisfied and gas pilot is ignited and proved by flame safeguard.

Discharge temperature controller maintains constant discharge air temperature.

Modulating solenoid opens/closes gas valve as ordered by controller.

Controls discharge duct air temperature.• Standard unit develops a maximum discharge temperature of 90°F. For optional discharge temperatures, contact factory.

Construction FeaturesThe Hartzell pre-engineered make-up air systems, when properly applied, eliminate hot and cold spots, supplying fresh clean air at the right temperature. Existing ventilation systems will work better, which accommodates more effective employees and production systems.Hartzell offers a broad range of axial and centrifugal mod-els. These are modular units that can be configured to meet your requirements.

Hartzell gas fired intake units are completely packaged, factory assembled and tested before shipment. These units are easy to install, easy to operate, low in cost and low in maintenance.

Optional controls such as remote station, which is typically mounted at the floor level and consists of start and stop push buttons and fan/heat selector switch.

Basic Operation and ControlsAll Hartzell Model GMP and GMC direct gas fired make-up air heaters are provided with a control system as standard. This system includes the master control panel mounted in a Nema 4/12 external control cabinet enclosure. It consists of the motor starter, or control transformer, terminal strips, airflow switch, flame management system, burner modulation control and temperature controls. Standard control package includes state-of-the-art, commercially available components such as Maxitrol air temperature control system, Honeywell Series 7800 flame safeguard system and electronic temperature and pas-sive limit controls. Specific models may change depending on optional controls specified.A description of the Hartzell controls follows:

Optional Recirculating Unit ControlsManual Operation

Optional Face and Recirc Feature: During downtime, recir-culating shutters are closed. Upon start-up, Recirc Shutter moves to whatever position the “Return Air” controller is set, up to 80% recirc air. The Shutter at the Burner moves con-versely to the above Recirc Shutter.

Automatic OperationAutomatic modulation for face- and Recirc Dampers. Dampers are modulated based on internal building pressure. Set point can be adjusted on controller at remote station.

If a pressure signal is supplied, a controller reads the signal and compares it to the controller setpoint.

The controller then provides an output signal to the damper actuators to modulate the return air and burner (outside air) dampers. This maintains proper airflow velocity across the burner.

Construction is galvanized steel with fully welded seams.

Air recirculation feature available on both centrifugal (GMC)and propeller (GMP) models, is designed to provide continuous building air make-up, pressurization, and heating with maximum efficiency. These self-contained units are fully factory wired, plumbed, assembled and tested. They are designed to provide control of the make-up air volume, via pressure or manually adjust-ed potentiometer. Units are direct fired, designed to burn either

natural gas or propane with 20% to 100% fresh air intake and 0% to 80% recirculated air. This allows recirculation of clean plant air when heating, pressurization requirements and exhaust loads are at minimum levels.

Heating has always been a problem in plants, warehouses, factories, etc., when overhead doors are frequently opened and closed. The rushing in of cold air when the doors are open chills personnel and lowers their working efficiency.Normal heating systems, such as unit heaters or duct systems, are not capable of handling this problem. Furthermore, an extra, sudden load is thrown on the heating system and as a result, heating costs rise substantially.This bothersome and costly problem can be solved by the Hartzell Automatic Door Heater which directs a blast of high velocity heated air toward the door opening. As a result of the turbulence created, the hot air mixes with the cold air, and the “bite” of the cold air is eliminated.

The Hartzell unit works whenever the door is raised far enough to trip the switch. The fan starts, after a brief pre-purge time period, and safety function check, a high velocity stream of heated air is blasted into the cold entering air.Hartzell Automatic Door Heaters come equipped with Duct Axial propellers designed for high velocity at medium noise levels.These heaters can be mounted in either horizontal or vertical position or at any angle in between. Every Hartzell Automatic Door Heater is completely assembled and tested at the factory and is shipped ready for installation. Generally, the only instal-lation requirement is connecting a unit to the electrical and fuel supply systems.

HARTZELL FAN, INC.

Face and bypass units provide better temperature modulation in marginal, as well as, extended cold weather by varying the air-flow through the coil by means of proportioned face and bypass dampers. The damper enclosure is designed with a plenum chamber containing guide vanes providing for proper mixing of air.The result is modulating temperature control with full steam pressure at all times reducing the problem of coil freeze-up. The face and bypass section is available in two designs utilizing a Hartzell duct axial fan (Series SAH) or a DWDI forward curve centrifugal fan (Series SCH). Both are designed as packaged units with controls mounted and wired.

Features:Series SAH – Axial Units• 8,000 to 45,000 CFM...works up to 1” external static pressure.• Utilizes the Hartzell 6-bladed duct axial fan.• Vane section available for higher static pressures up to 3” external.

Series SCH – Centrifugal Units• 8,000 to 45,000 CFM...works up to 11⁄2” external static pressure.• Utilizes a DWDI heavy-duty industrial forward curve wheel.

Series 77 Steam Unit Heaters

Series 77 Steam Unit (1-Row)Series 77 Steam Unit (2-Row)

Hartzell direct drive steam unit heaters are powered to utilize the full high heat transfer efficiency of the unit by efficient translation of power into air movement.The characteristics which make a unit heater so superior to heating devices which depend on radiation are the ability to quickly extract a very high proportion of the heat contained within the primary heating element and to distribute that heat evenly.The key to economy and quality of performance lies in the propeller which forces air through the heater and distributes it evenly and thor-oughly into all corners and recesses of the area to be heated.The Hartzell steam unit heater is equipped with either 1-row coils (Series 771) or 2-row coils (Series 772) of the fin and tube type, high efficiency cast aluminum propeller direct connected to a totally enclosed fan duty motor. Two 1/2” – 13 N.C. tapped holes for support rods provided. See page 3 for performance data. Special coil sections may be provided to meet specific application requirements.The Cores in unit heaters have copper headers and seamless copper tubes with copper brazed joints, and copper fins. Varied fin spacing. Cores are guaranteed up to 150 psig saturated steam and 366°F.Standard mounting of the steam unit heater is in vertical position, capable of being tilted as much as 60° downward.Rugged steel support rods and motor base are standard on Hartzell steam unit heaters.

The Ideal Heating Unit• Initial Cost – Lower per square foot of area to be heated than any other method of heating.

• Installation Cost – May be installed in about a fourth of the time required for radiation.

• Heat Circulation – Distributes heat thoroughly. Eliminates cold spots and cold floors.

• Space Saving – Suspended along a wall, beam or ceiling, the average Hartzell unit heater saves at least 45 square feet of usable floor space.

• Instant Action – Touch a switch when heat is needed (or do nothing at all if thermostatic control is used) and heat is produced instantly... no waiting.

• Louvers – Adjustable louvers can be individually set to deliver heat at the exact point desired.

• Appearance – Fabricated steel cabinet with air dry enamel coating.

Tips on Placement of Unit Heaters• Place units at the points of greatest heat loss (doorways, windows, etc.)

• Place heaters so that the air stream wipes the outside walls, and the throw from one heater reaches to the next unit. This sets up a circulatory air movement that produces a blanket of warm air along the cold wall.

• Arrange units so they do not blow directly on workers. Aim air streams down aisles, toward open spaces on the floor, or along exterior walls.

• Locate heaters so that air streams are not blocked by columns, machinery, partitions, etc.

• Position units in a building or exposed to a prevailing wind to direct a large portion of the heated air along the windward side.

Accessories:• Safety Guard – Protective rear safety guard of 14 gauge steel is available as an option.
