PSD vs HelitorchPSD vs Helitorch

Ref: IAIG Ch III Table 2

Advantages of PSD• Better Control

– Firing Boss onboard helicopter

– operator can assess / address problems

– operator can monitor qty of spheres remaining

• Less Complex– separate helibase not required

– spheres safer to transport and handle

• Lower Cost– lower equipment cost

– less support staff

• Fire Behavior– minimum damage to tree canopy

– possible to lay very long ignition lines

PSD vs HelitorchPSD vs Helitorch

Ref: IAIG Ch III Table 2

Disadvantages of PSD• Fire Behavior

– spheres burn for a shorter time

– cannot duplicate helitorch drop pattern

– fire lines take longer to form

• Safety

– possible fire in PSD

– requires constant operator attention

– Pilot cannot jettison PSD

Premo PSD Electrical SpecificationsPremo PSD Electrical Specifications

Power is supplied to the dispenser from the aircraft power supply (24V DC) through a quick-disconnect fitting. A central control panel contains all the electrical components and switches to operate the different stations such as the main drive, glycol pump, slow-fast speed and the emergency water supply. The switches are series wired so that the drive motor can be operated independently of the pump but the pump will not operate unless the drive motor is turned on. This allows cycling of unprimed spheres for testing. Caution however, should always be taken, as a small amount of glycol may enter a sphere even if the glycol pump is not on. Care should be taken to dispose of these test spheres appropriately. (See Section 6 of Premo PSD manual for electrical schematics.)

Premo Fireball SpecificationsPremo Fireball Specifications

Diameter 1.25 in 32mm

Potassium Permanganate 0.11 oz 3.0 g

Total Mass 0.17 oz 4.8 g

Shell Material High Impact Polystyrene

Ignition Delay 20-30s @ 50°F

Note: fire ignition sphere performance can be affected by the following factors.

• Temperature (primarily temperature of glycol but also spheres)

• Glycol volume (low injected volume can yield quicker reactions)

• 50/50 premix glycol can increase delay times significantly

• Calibration typically occurs using glycol volumes between 0.6-1.0cc

• Humidity can also impact ignition delay rates

Ethylene GlycolEthylene Glycol

Which Antifreeze?• Use Standard Vehicle Antifreeze (90 - 100% Ethylene Glycol)• Do not use Propylene Glycol Antifreeze (Non-Toxic)

Repair & MaintenanceRepair & Maintenance

• Fuses 5A, 2A, 2 amp circuit breakers (Klixon)• Needles (set of four)• Valve springs (set of four)• “O” rings for valve stems (set of four)• Pump• Drive motor• Bulbs for indicator lights• Solenoid

Recommended Spare Parts

Note: The motors used for the main drive and the hopper are identical, however, the hopper motor uses the high-speed wire for its operation. The pumps used for the glycol and the emergency water are also identical. It is therefore only necessary to carry one of each to ensure rapid replacement. It is recommended to carry a supply of EMPTY spheres for bench test procedures.

Field Service Tools & SuppliesField Service Tools & Supplies

• 1/8 and 3/16 Slot screwdrivers• No.0, No.1 and No.2 Philips Screwdrivers• No.1 Robertson screwdriver (square drive)• Set of Imperial Allen keys• Set of wrenches (5/16, 3/8, 7/16, ½, 9/16, 5/8, 11/16)• Adjustable pliers and adjustable wrench• Wire cutters and wire strippers• Soldering iron and solder

Premo PSD CleaningPremo PSD CleaningCleaners & Lubricants• Use Citrus Based Cleaner / Degreaser• No Petroleum Based Lubricants

Daily CleaningDaily Cleaning

• Wipe down hopper

• Check linkages for wear

• Inspect glycol & water pumps and hose connections

• Clean using cloth and cleaner / degreaser as required

• Check condition of needles and sharpen as required

• Check pump(s) operation

• Clean needle block assembly area regularly

• Clean using a cloth and cleaner / degreaser

• Check for smooth operation and signs of wear

• Check tanks and lines for signs of leakage

Long Term StorageLong Term Storage

Drain Tanks• Drain the glycol tank• Drain the water tank• Store PSD indoors at room temperature

Long Term StorageLong Term StoragePSD & Fireball storage• Store PSD indoors at room temperature

• Store PSD spheres in a dry location to avoid humidity

• Confirmed, specific shelf life is not currently known exactly but reducing stored spheres from exposure to humidity can extend the life of the spheres and see consistent performance over many consecutive years. Boxes should be agitated annually.

Power Failure• Notify the pilot of the situation.• Clear machine of any injected spheres• Investigate the cause of the power failure

Sphere Jam• Notify the pilot of the situation.• Stop feed gates• Clear machine of jammed sphere• Failure to clear may lead to fire in dispenser.


Fire in Dispenser• Notify the pilot of the situation.• Press and hold the emergency water switch until the fire is

extinguished.• If the emergency water pump fails to extinguish the fire, pour

water from the canteen into the hopper.

Fire Extinguished• Switch the RUN/STOP switch to the STOP position.• Watch the machine for 3 minutes for possible smoke before

leaving the ignition unit.• Land and perform manual and visual inspection to identify

and solve the problem.


Fire not Extinguished • Notify the pilot of failure to extinguish fire.• If necessary, uses additional container of water to extinguish

fire by pouring down feed chutes in hopper. If problem persists, land as soon as possible.

• Notify Pilot of problem status and take appropriate actions.
