GENERAL INFORMATION


DESCRIPTION

This chapter outlines the physical and functional description of the Premier “Express Heat” Deicer. A complete description of the unit and its features are included. The Premier Engineering & Manufacturing, Inc., “Express Heat” series aircraft deicer is a truck mounted unit featuring a high capacity single pass fluid heating system. The “Express Heat” system results in a deicer that is simple to operate and extremely easy to maintain. The “Express Heat” system requires only 90 seconds of preheat time prior to full operation.

Throughout this manual reference to “deicing” and “antiicing” will be made for the purpose of describing a component and/or system. The term “deicing” will refer to the deicing fluid system and “antiicing” will refer to the agent or system to be used for the antiicing process. The purpose for this distinction is due to the ever changing fluids utilized in antiicing process.

GENERAL INFORMATION

The “Express Heat” series deicer is equipped with a 20 kW, 240 volt, 3 phase, AC generator. The generator features a patented inherent regulation, and does not require a voltage regulator. The sealed bearings are rated for a 1,000,000 hour service life.

DANGER : WHEN WORKING ON THE GENERATOR, ALWAYS INSURE THE

AUXILIARY ENGINE IS OFF AND THE AUXILIARY ENGINE BATTERY CABLE IS DISCONNECTED. MISHANDLED GENERATOR HIGH

VOLTAGE CAN RESULT IN SERIOUS INJURY AND OR DEATH.

The generator supplies the necessary power to operate all of the deicer systems. The generator is direct coupled to a 3 cylinder, JetA fired, liquid cooled auxiliary engine. The auxiliary engine runs at 1800 RPM to provide the required 60 cycle frequency current. The auxiliary engine is fueled from the same fuel storage tank as that of the fluid heating system and has a slave fuel pump and filter mounted on the frame of the chassis just after the fuel storage tank to assist in supplying fuel to the generator.

FIRE SUPPRESSION SYSTEM

Installed on the deicer is an Ansul fire suppression system. This system is a manual or automatic activation system which utilizes a PurpleK agent for the fire suppression. The automatic system has three temperature sensitive fusible links which activate electronic charge. The electronic charge is then directed to an expellant gas cartridge thus discharging the fire suppression agent. The system may also be manually activated with a plunger style switch located on the back of the cabinet. Regardless of the method of activation, the release of the fire suppression agent automatically discontinues the operation of the auxiliary engine. The auxiliary engine will not restart until the system has been reset in accordance to the Ansul recommendation.

Fluid Flow Meter (OPTIONAL)

A digital fluid flow meter is mounted in the control panel in the chassis cab for a constant monitoring of the fluid dispensed.

DEICE FLUID SYSTEM

FLUID STORAGE TANK

The “Express Heat” deicer series offers a 750 to 2000 gallon capacity, polypropylene fluid storage tank, with optional tank configuration for deicing / antiicing combination. The tank is manufactured using compression molded, stress relieved, virgin polypropylene. A 10” fill port is located on the drivers side of the tank and can be removed to access the tank through a 22” square opening. All of the plumbing is attached to the tank utilizing poly bulkhead fittings. Although the tank is constructed of polypropylene, it is capable of storing fluid up to 110 degrees F. The fluid level gauge is a sight style located on the drivers side of deicer cabinet. The sight gauge is simply a slot in the cabinet which you look through to see the level in the tank. For night time use, the fluid tank is illuminated for clear visibility of the fluid level.

FLUID DELIVERY SYSTEM

The fluid delivery system on the “Express Heat” deicer consists of a high speed, high temperature, internally regulated 7 stage centrifugal pump driven by a 7 ½ hp, 240 volt, 3 phase, electric motor. The electric motor rotates at 3450 RPM and is direct coupled to the fluid delivery pump. There is a low fluid shut down switch located adjacent to the antiicing fluid storage tank. The low fluid shut down switch discontinues the operation of the fluid pump when the level of the fluid drops below the 50 gallon level. This will prevent the pump from inadvertently being run dry causing permanent damage to the pump. The fluid delivery system takes fluid from the tank, through the fluid pump, diverts the fluid in equal amounts and in a parallel configuration through the three heaters and out of the dispensing guns. If the fluid delivery guns are not in the open position, the fluid pump does not circulate fluid through the heating system and simply cavitates within the fluid pump.

NOTE: Extended periods of cavitation will cause serious damage to the fluid delivery pump. The fluid pump should not be allowed to operate in the cavitation mode for longer than 5 minutes.

A ¼” fluid line is needed to return a small portion of the fluid in the pump back to the fluid storage tank for reasons of cooling the fluid pump during extended cavitation. Also, in the fluid delivery system, down stream from the fluid heaters is a “Cold Fluid Purge” valve. This valve is used to circulate cold fluid through the fluid heaters in the start up procedure. The cold fluid purge process should take approximately 90 seconds. On the exit port of the cold fluid purge valve is a constrictive port. The port is used to regulate the fluid flow through the cold fluid purge valve during the purging process. Because the fluid delivery pump will produce a high fluid flow rate at a lower pressure, this constrictive port serves to reduce the flow of the fluid through the heaters during the purging process. Fluid directed to the aerial lift dispensing gun is


delivered through a cat track assembly located on the top of the aerial lift. Fluid directed to the lower dispensing gun is via 100’ of 5/8” hose on a 12 volt DC power retract hose reel.

ANTIICING SYSTEM

The Premier Antiicing System option includes a tank configuration of customers choice, a Hardi diaphragm style pump driven by a 3 hp, 230 volt 3 ph, 1100 rpm motor. A speed control is used to vary fluid pump pressures. The speed control breaks down the frequency of the power going into the antiicing motor thus varying the speed, an additional aerial lift Cat Track assembly, an antiicing delivery gun located at the basket of the aerial lift, and a selector switch located at the basket of the aerial lift for selection of fluid to be dispensed. Antiicing fluid cannot be dispensed from the ground. When the selector switch is in the Type I position, the antiicing fluid pump is not in operation. When the selector switch is in the Type II position, the deicing fluid pump is not operational, i.e. both deicing and antiicing fluid cannot be dispensed simultaneously. The antiicing system is operated on a pressure sensitive switch located adjacent to the antiicing pump. As the antiicing dispensing gun is closed, the pressure in the system, approximately 50 PSI, activates the pressure switch and discontinues the power to the antiicing pump motor. The antiicing tank is located aft of the deicing tank and the level of the fluid is measured by a sight gauge located on the drivers side of truck. Filling of the antiicing fluid tank can be accomplished by using the antiicing pump and a small series of adjustments to the valving. For additional information on the suction filling of the antiicing fluid, refer to the Type II (Antiicing) Plumbing Schematic.

FLUID HEATING SYSTEM

FLUID HEATERS

The fluid heating system features 3 single pass coil heat exchangers aligned in parallel. The burners, which are ignited by JETA/ DIESEL , via a two pipe system and are located on top of the coil assembly and propel the flame downward and then back upward, toward the exhaust port. The heat exchanger coil is wrapped in one layer of 16 gauge galvanneal and insulated with ½” high density refractory fiber. A second outer layer of 18 gauge 304 stainless steel completes the coil shrouding. There is an 80 sq. in. exhaust port located at the top front side of the heater coil assembly. The fluid to be heated enters the heater coil, passes through approximately 190’ of tubing and then exits the heater coil. Located on each heater assembly is a fluid flow switch and a fluid thermostat. The fluid flow switch and the fluid thermostat are wired in a series with the burner primary control. The burner primary control activates and deactivates the burner fuel solenoid. Simply stated, the operation of the heater consists of the following;

1. The Heater ON/OFF switch is put in the “ON” positionThis energizes the burner blower motor. The blower motor, via a thermo couple, rotates the burner fuel pump. Additionally, the blower motor rotates the “squirrel cage” providing the combustion air to the burner. Simultaneously, the burner transformer is energized and excites the electrodes located in the burner chamber.

2. The “Honeywell Primary Control” awaits the signal from the fluid flow switch and the fluid thermostat switch. When either the fluid dispensing gun and/or the “Cold Fluid Purge” valve is opened, fluid will begin to pass through the burner coils. At this time, the fluid flow switch will sense the flow and send a electronic current to the fluid thermostat. Provided the fluid flowing through the coils is not greater then the setting on the fluid thermostat, the electronic current will be sent back to the “Honeywell Primary Control” completing the circuit. Completing this series circuit activates the “Honeywell Primary Control”.

3. The Fuel Solenoid receives the electronic current to activate the “Honeywell Primary Control”. When the fuel solenoid opens, fuel is allowed to enter the burner chamber, passing through the burner nozzles at approximately 130150 PSI. Utilizing the spark made by the excited electrodes, the atomized fuel begins to burn until either the fluid flow stops or the fluid flowing through the burner coil reaches the preset temperature noted on the fluid flow thermostat.

12aELECTRICAL SYSTEM


ELECTRICAL SYSTEM

The electrical system is a combination of 12 volt DC current and 240 volt, 3 phase, AC voltage. Where possible, the wiring is marked with exterior wire markings indicating the service of the wire, voltage of the wire, size of the wire and the style of wire. Most applications permit the use of oil resistant, water resistant S/O cord.

All AC voltage is directed from the generator to a load center located in the back of the deicer cabinet. There is not a main circuit breaker for the power input source, however , each individual circuit is terminated through its own respective breaker. Additionally, all of the wiring from the load center to the interior control panel is 115 volt AC. All of the 240 voltage is direct to the components via a magnetic contactor that has a 115 volt activation. All of the magnetic contactors are located in the load center.

ELECTRICAL SYSTEM

CONTROL PANEL

The deicer function controls are located in the chassis cab of the deicing unit. All deicer components are equipped with a rocker style illuminated switch. When the switch is in the “OFF” position, the rocker switch will be in the nonilluminated position. Conversely, when the rocker is in the “ON” position, the rocker switch will be illuminated. All heater switches are accompanied by an ignition light located directly above the corresponding rocker switch and indicates the burner operation of the burner. In addition to the components function switches, the control panel is equipped with an auxiliary engine ignition switch, auxiliary engine preheat indicator, auxiliary engine low oil, over temperature, and charging system warning light and “Tattle Tail” override. Also included on the control panel is a fluid temperature gauge. The control panel is mounted via a pedestal to the floor of the chassis cab. All the wires and capillaries are run through the back of the cab, along the cab floor, and through the pedestal mount. Finally, the center of the control panel.

COMMUNICATIONS SYSTEM

The installed Communication System allows the individual in the aerial lift to remain in contact with the individual in the chassis cab. A David Clark communications system, which is voice activated, is installed utilizing a chassis cab master station, and an aerial lift basket mount remote station. The two stations are interconnected via a 22/3 shielded wire through the inner portion of aerial lift. The master station is powered by 12 volt DC from the chassis fuse panel. The ground level station is equipped with a single ear headset, and the basket is equipped with a dual ear headset. Both stations have volume control for their respective headset, and the master station has a system control for volume. Each headset is also equipped with a on/off button.

CHASSIS SPEED CONTROL

Incorporated into the chassis engine and the aerial is a speed limiter. This control limits the speed of the chassis to 4 MPH (5.87 FT/SEC) while the aerial lift is out of the stowed position. Activating the speed control is a proximity switch located at the tower support saddle. The actual speed control works with a potentiometer in the accelerator supplying power to the 12 volt motor located in the speed control box. This 12 volt motor receives impulses from the


speedometer so that the chassis engine will generate the power needed to achieve the 4 MPH. When the lift is in the stowed position, the chassis operates with full function.
