Piranha Fire Suppression System:


The only agent-plus-water fire suppression hybrid on the market today, Ansul Piranha systems outperform all conventional single-agent systems on a number of fronts. Ansul Piranha systems attack fire using the rapid flame knockdown and securing capabilities of PRXTM Liquid Fire Suppressant. Then, the superior cooling effects of water follow, quickly cooling the cooking media and further helping to prevent reflash.
Ansul Piranha systems employ the best firefighting attributes of two extinguishing agents...

  • The fast flame knockdown and securing power of wet chemical.
  • The fast cool-down capability of water.
  • Twice the coverage of conventional single-agent systems
  • Cools down cooking oils 15 times faster than wet chemical systems
  • Flexible overlapping nozzle coverage for most appliance arrangements
  • Smaller and fewer agent storage tanks required per system


Applications Best Suited for Ansul Piranha Fire Suppression System

  • Casual & Fine Dining
  • Fast-Food Chains
  • Culinary Schools
  • Sports Complexes and Stadiums
  • Four- and Five-Star Lodging Facilities

In UL300 testing, the Ansul Piranha system cooled hot grease 15 times faster than single-agent wet systems, required 60% less chemical agent, covered hazard areas better and provided a cost-effective means to protect the cooking equipment.

Ansul Piranha systems are available in various sizes that can be combined for multiple configurations to expand the suppression system coverage. Depending on your type of facility, we will design a system that offers you the ultimate in fire protection.

Tests using the “Double-Agent” Concept have shown dramatically increased firefighting performance.

Amerex offers two systems to meet the industry's varying needs.

Amerex KP Restaurant Fire Suppression System

The Amerex KP Restaurant System is a pre-engineered, wet chemical, stored-pressure type with a fixed nozzle agent distribution network. The system agent is Amerex KP liquid fire suppressant, a potassium acetate based solution that suppresses cooking grease fires both through saponification and cooling. The agent has a pH of 9 or less and does not harm stainless steel surfaces.

When a fire starts, the detection network, consisting of fusible links or pneumatic tubing, will automatically detect the fire or the manual pull station can be used, releasing a low pH agent throughout the hood, duct and onto the appliances.Either method of actuation will interrupt gas or electrical power to the appliances preceding system discharge. The Amerex KP agent quickly suppresses the fire and cools the fuel while securing the vapors with a smothering foam reaction.

Applications Best Suited for Amerex KP Restaurant Fire Suppression System

  • Casual Dining
  • Fast-Food Chains
  • Cruise Ships
  • School Cafeterias

Buckeye Kitchen Mister Fire Suppression System

Open flames, red-hot cooking surfaces, and a heavily grease-laden environment combine to make the modern commercial kitchen a potentially dangerous fire hazard. Kitchen fires spread quickly and have proven to be very difficult to extinguish, making them the leading cause of structural fire damage in the United States.

Protecting the modern commercial kitchen from the ever-present danger of cooking oil and grease fires is the reason we developed The Buckeye Kitchen Mister™ System. Utilizing state of the art misting technology, the Kitchen Mister System has proven to be the most effective fixed kitchen fire extinguishing system ever developed, extinguishing potentially deadly kitchen fires fast, before they can spread.

That’s why the Kitchen Mister System is quickly becoming the preferred choice of fire protection professionals throughout the world.

Simplicity Of Design
The constant changes and complicated requirements of most restaurant systems have made design and installation errors a concern of fire protection professionals globally.The uncomplicated design of the Kitchen Mister System all but eliminates design and installation errors by combining common sense features and the elimination of confusing design requirements.

Faster Installations

By eliminating the labor-intensive task of installing conduit, corner pulleys, and detector brackets, the Kitchen Mister System dramatically reduces installation time.

The Kitchen Mister System is approved for use with Buckeye Shielded Cable instead of traditional conduit and corner pulleys for all system inputs and outputs. This, combined with the elimination of conduit and fusible link brackets in the plenum area, makes installing the Kitchen Mister System quick and easy.

  • Automatic detection and actuation controls provide 24-hour protection.
  • Dedicated manual pull station allows immediate actuation at the first sign of fire and provides backup to the automatic detection system.
  • Premium extinguishing agent provides rapid flame knockdown and helps prevent re-ignition.
  • Pressurized D.O.T. rated steel cylinders ready for release in the event of a fire.
  • Pressure gauge on the agent cylinder allows visual inspection of system status.
  • Fully assembled and 100% tested mechanical control head, cylinder valve, and gas shut-off valve provide reliable operation.
  • Flexible piping configurations allow for a streamlined design that will not interfere with kitchen workflow. The system can be mounted in out-of-the-way areas to preserve valuable kitchen space.
  • Flexible conduit allows for ease of installation. The conduit is easily hidden behind existing pipes or behind the wall.
  • Protective chrome nozzle caps help protect against contamination and blockage by grease or other cooking byproducts that can inhibit the proper discharge of extinguishing agent.
