It’s tested and approved for grease fires and activates automatically when exposed to direct flame contact, releasing a fire-suppressing agent for fast control of flames.
Installation is straightforward with magnets included for mounting under the range hood. The system targets the area most prone to grease fires, delivering reliable, fast response right where it’s needed most.
HOODMART UL/NSF 6′ Concession Trailer Hood System
This commercial hood system is engineered for food trucks and concession trailers, with a low-profile stainless steel hood design to maximize clearance. It includes a pre-piped fire suppression system and is NSF/UL approved, backed by a two-year warranty, ensuring dependable factory-tested performance.
The kit is designed to safely vent heat, smoke, and grease-laden vapors while providing automatic fire suppression when needed. It’s a strong choice for mobile food service operations seeking code-compliant protection.
HOODMART UL/NSF 8′ Concession Trailer Hood System
Designed for larger concession setups, this 8-foot hood system maintains American-made quality with NSF/UL approval and a two-year warranty. The kit includes everything needed for quick installation, creating a reliable, restaurant-grade fire protection solution for bigger mobile kitchens.
As with the 6-foot version, it is purpose-built to handle grease-laden vapors and heat, helping prevent grease fires from spreading to equipment and ductwork.
FD Supply Co. Fire Suppression Nozzles Caps
Metal blow-off caps protect Ansul R102 or Piranha kitchen suppression vent hood systems by sealing nozzle openings and preventing grease buildup. This helps ensure system reliability and compliance during inspections, with a simple, tool-free installation that fits standard nozzle fittings.
Regular maintenance and proper cap sealing are important to sustain nozzle performance and fire suppression readiness in busy kitchen environments.
HOODMART UL/NSF 12′ Concession Trailer Hood System
This 12-foot hood system offers extended coverage for larger mobile cooking setups, maintaining the same safety and reliability standards as smaller HOODMART units. It’s NSF/UL approved and includes install-ready components to simplify installation and compliance checks for food trucks and trailers.
Choosing the right length helps ensure complete protection over all cooking equipment, reducing the risk of grease fires spreading through exhaust ducts.
Buying Guide
Key considerations when selecting an automatic fire suppression system for kitchen hoods:
- Residential vs. commercial: Residential systems are designed for home kitchens, typically focusing on stove-top greases and smaller footprints, while commercial systems cover larger hoods and higher heat exposure in restaurants or food trucks.
- Code compliance and approvals: Look for UL and NSF listings, which indicate compliance with industry safety standards and inspections.
- Response type and activation: Direct flame-activated systems offer immediate suppression where flames are detected; delivery agents and nozzles should match your hood configuration.
- Installation ease: Systems with pre-installed kits or magnetic mounting simplify under-hood installation in homes; commercial systems may require professional installation.
- Maintenance and parts availability: Consider systems with widely available replacement parts (nozzles, caps) and simple maintenance routines to ensure ongoing reliability.
- Coverage and customization: Ensure the system length and nozzle placement effectively cover the cooking surface and ductwork areas where grease fires are most likely to start.
- Warranty and support: A robust warranty and responsive customer support help address any service needs after installation.
In evaluating options, weigh the balance between household convenience and professional-grade protection. For high-traffic commercial kitchens and mobile operations, systems with pre-piped kits, longer hood coverage, and factory approvals offer stronger long-term value despite higher upfront costs. For residential kitchens, compact, magnetically mounted units that activate automatically provide practical protection without complicating aesthetics or installation.
