Fire trucks and rescue apparatus spend large portions of duty cycle parked at station, in pre-positioning standby, or at incident scenes. Engine idling for cab comfort wastes fuel, accelerates engine wear and adds NOx to the station bay air. Battery parking AC is the standard upfit on modern fire service vehicles.

Station-bay air quality and idle reduction

Most US fire departments have idle-reduction policies driven by NFPA 1500 firefighter health guidelines. Battery parking AC eliminates cab idling and improves apparatus-bay air quality.

On-scene incident command — long stand-by

Command vehicles often stand by for 4–12 hours at major incidents. A 280–450 Ah LiFePO4 auxiliary bank with VC 2000 24V supports the full duty cycle without engine run.

Heavy-vehicle vibration rating

Vethy mounting hardware is rated to ECE R10 / EN 13262 vibration standards typical of fire service apparatus. Rooftop and under-bunk mounting options.

Recommended models for fire service

Pumper, ladder and rescue apparatus with 24V system: VS02 PRO 24V or VC 2000 24V. Smaller brush trucks and command vehicles: VC 1000 24V.

Power-take-off (PTO) charging integration

Fire apparatus PTO often runs the pump. Add a DC-DC charger off the engine alternator to recharge the parking AC battery during pump operation.

Frequently asked questions

Is parking AC compatible with NFPA 1901 apparatus?

Yes — installation must follow NFPA 1901 electrical chapter requirements; Vethy DC fuse and isolator kits are NFPA-1901 compatible.

Does the AC operate during pump engagement?

Yes — parking AC runs from the auxiliary battery bank, independent of pump PTO operation.

How loud is it inside the cab during overnight station stand-by?

Sleep mode 42–46 dB(A) — quieter than ambient apparatus-bay HVAC.

Will the battery last a 12-hour incident scene?

A 450 Ah LiFePO4 supports ~12 hours at 35°C ambient with VC 2000 24V. Larger banks possible for longer duty cycles.

Does Vethy supply public-sector procurement docs?

Yes — pricing schedules, warranty terms and W-9 / vendor onboarding. Email sales@vethy.com or call +86-532-87729918 for fleet specs, CIF pricing and OEM bracket kits within 24 hours.

Is the unit certified for ECE R10 EMC?

Yes — all parking AC models hold current ECE R10 approval.
