Fire & technical rescue

Ventilation fans, cutting and breaching tools, deployable floodlighting.

Starting configuration: P25-D · P25-T

At a fire, exhaust gas is the second hazard: ventilation fans, hydraulic breaching tools and cutters pull hard power inside buildings, and a diesel generator adds its own pollution to the environment you are clearing. The P25-T three-phase system drives the large tools at 7.5 kW / 8.1 kWh; the P25-D covers lighting and communications — zero emissions on scene, near-silence, IP54 for rain and debris. Peak loads from breaching and cutting belong on 400 V three-phase, not a single-phase drop. In the night window, every minute counts.

    Readiness is a charging schedule, not a battery rating

    2026-11-06 · By Zack

    A 2.7 kWh unit that carried a fan and two floodlights comes back needing hours on a 230 V socket, and the next call can arrive inside the same shift. Readiness at a station is a charging schedule, not a capacity figure.

    The fire is out and the supply is down: lighting the hours after the main switch

    2026-10-26 · By Zack

    The main switch is isolated before crews enter, and that is the right call. It also takes out every light, every socket and the escape lighting — at exactly the moment overhaul, investigation and the fire watch begin.

    The drill, not the incident, sets the energy budget

    2026-10-15 · By Zack

    Fire services work out their power requirement from the incident, but the incident lasts minutes and the training day lasts hours. The ventilation fan and the lighting are what actually spend the energy — and that is where the configuration gets decided.

    Power at the incident: what changes when the generator stays on the truck

    2026-09-25 · By Billy

    Three things a combustion generator does at an incident have nothing to do with wattage: it buries radio traffic, it puts exhaust where crews work, and it stops when the fuel runs out.
