PSD Machine description.pdf

This document is a product specification sheet for the Premo® Plastic Sphere Dispenser (PSD), a compact aerial ignition device designed for rotary wing aircraft. The device is constructed from aircraft-grade aluminum alloy and is engineered to safely inject Premo Fireballs with ethylene glycol and release them over targeted areas. Compatible with modern rotary wing aircraft like the Bell 206, the PSD features a 3.25L water reservoir for fire suppression, a multi-stage injection mechanism, and anti-jam slipper blocks that control sphere deployment.

Key features include high mechanical reliability, a dispensing rate of 45 to 130 drops per minute, manual reset circuit breakers, and a rugged aluminum storage and transportation case. The system allows operators to adjust sphere dispensing rates based on flight speed, burn assessment, topography, and grid spacing. The device is designed for easy maintenance, with components that can be quickly replaced in the field, and comes with an industry-leading warranty. It is primarily used in aerial firefighting applications and can be configured with modified support brackets for various aircraft models.
