Premo Plastic Sphere Dispenser

Compact, dependable launcher suitable for most rotary wing aircraft

About the Premo Launcher

The Premo Plastic Sphere Dispenser (PSD) is a compact and dependable aerial ignition device dispenser. Made of aluminum, it is designed to safely inject Premo Fireballs with ethylene glycol and accurately release them over targeted areas.

The Premo PSD works with most modern rotary wing aircraft including the Bell 206 and other flat floor models from various manufacturers. The controls are easy to learn and operate and are designed to prevent the accidental release of ignition devices. Each sphere is injected with ethylene glycol before being expelled from the aircraft and landing in the target area, to guarantee ignition seconds later.

As a safety feature, the Premo PSD is equipped with a 3.25L water reservoir that is engineered to extinguish a potential fire within the injecting area. Jams are quickly cleared so that downtime is minimized and air time is maximized.

Quality Construction

The Premo PSD is constructed from an aircraft-grade aluminum alloy that is corrosion resistant, yet lightweight. All the components, including pumps and motors, are engineered for toughness, reliability and ease of maintenance. Since safety is paramount during any aircraft operation, these products are dedicated to quality construction. We inspect and test every unit for trouble-free action before it is shipped to customers, allowing them to get off the ground and working without delay.

n situations where field service is required, all major components are easily accessible and replaced within minutes. For maximum safety, the Premo PSD carries a 3.25 L water reservoir. In the unlikely event of a jam, the fire suppression system delivers a blast of water directly to the injection area to immediately extinguish any flames.

This PSD is shaped to fit the rear door sill of the Bell 206 helicopter and can be configured to any aircraft using modified support brackets. The main frame consists of the power train, hopper, glycol reservoir, fire suppression system, sphere dispensing mechanism and a glycol injection mechanism. The mechanism feeds the spheres into four chutes which are controlled by anti-jam slipper blocks. The slipper mechanism moves the spheres into the glycol injection needle. Immediately after being injected with glycol, the spheres are jettisoned out of the machine.


Easy to Use

Controls for the Premo PSD are easy to use with a minimum of operator manipulation. A standard 24V aircraft power supply powers the unit. The feed mechanism and glycol injection system can run independently, allowing the operator to test and make adjustments before take-off. You can manipulate the variable dispensing rate effortlessly depending on your flight speed, burn assessment, topography, under story fuel conditions and grid spacing.
