If you are looking for a world-class fire suppression system, you might wonder how much an ANSUL® system costs. For business owners, it’s vital to consider the expenses of fire suppression systems in comparison to the costs of their commercial cooking equipment or business operations.
If you run a food truck, restaurant, or industrial kitchen, having a restaurant fire suppression system is crucial for safeguarding your equipment and staff while adhering to local Fire Department laws.
As a result, it’s important to recognize the factors that influence the price range of an ANSUL® fire suppression system.
How Much Does an ANSUL System Cost?
An ANSUL R-102 fire suppression system typically costs $3,000 to $5,500, and a matching commercial kitchen hood adds $6,500 to $7,500. The R-102 uses a low pH liquid agent designed to work with a wide range of cooking appliances. Pricing varies by kitchen, so Industrial Fire provides free quotes.
ANSUL®, like any successful company, has multiple product offerings, from electronic detection systems to wet chemical system fire suppression products. However, before exploring the fire suppression products offered by ANSUL®, let’s discuss the pertinent factors affecting fire suppression system cost.
How Does an ANSUL Kitchen Suppression System Work?
When an ANSUL kitchen system detects fire, it shuts off gas or electric power to the cooking appliances and discharges wet chemical agent through nozzles over the appliances, plenum and duct.
Before exploring the different aspects that affect fire suppression system cost, there is one important factor to consider.
If you want an ANSUL system installation in Houston, make sure you purchase it from an authorized ANSUL® distributor. Not only will this ensure that your system is installed correctly, but it will also help your business maintain your ANSUL® system over time.
What Drives the Cost of an ANSUL System?
The number of agent tanks is the biggest ANSUL cost driver, because longer hood lines and more appliances need more tanks, nozzles and detection points.
The driving factor that determines the costs range for all fire suppression systems is the number of tanks required to protect the fire hazards in question. If your hood system requires more tanks, the cost will be higher. The number of tanks you need for your ANSUL® system depends largely on your space or kitchen characteristics.
The type and size of the space in question will significantly impact the number of nozzles, wall brackets, hood penetration seals, tanks, and detection brackets needed to protect your business from fire. Obviously, larger hood systems will cost more to protect with a fire suppression system than small spaces.
What Does ANSUL System Maintenance Cost?
Budget for ANSUL inspections every six months, as NFPA 96 requires, plus semi-annual fusible link replacement; larger multi-tank systems cost more to inspect.
Beyond system design and installation, the other factor that will drive costs is regular maintenance and inspections. However, these costs are trailing expenses because you won’t have to worry about paying them upfront. Still, if you have an ANSUL® fire suppression system or any other, you must have regular inspections and maintenance.
It would be best to consider this an expense when determining your annual budget for fire safety measures. Whether you are interested in dry chemical systems or a wet system, semi-annual inspections and maintenance should be budgeted. These services are associated costs, and it is helpful to consider them when trying to figure out how much an ANSUL® fire protection system will cost your business.
It is also essential to understand that the cost of your ANSUL® maintenance and inspection services will also be affected by the number of tanks your system has. The larger your fire suppression system is, the more expensive inspection and maintenance services will be.
Every location and kitchen is different, so it is difficult to guess how much an ANSUL® fire suppression system will cost your business until a certified professional is able to assess your needs.
Which ANSUL® Restaurant Systems Are Available?
ANSUL® offers three main restaurant fire suppression options in the U.S., the R-102 wet chemical system, the PIRANHA dual-agent system and the ANSUL® RED electronic detection system, each at a different price point.
ANSUL® is an industry leader in fire suppression systems. In the United States, ANSUL® offers three unique fire suppression systems. Each fire suppression system starts at a different price point. As stated earlier, your costs will depend on the size and specifics of the location you are trying to protect from fire. Let’s learn more about the fire suppression system offerings from ANSUL®.
ANSUL® R-102 Fire Suppression System
The ANSUL® R-102 is a wet chemical system whose low-pH ANSULEX agent knocks down grease fires, cools hot surfaces and forms a vapor-blocking layer that prevents re-flash.

The ANSUL® R-102 fire suppression system is a very popular choice for commercial kitchens in various businesses, including fast-food restaurants, stadiums, hospitals, food trucks, hotels, schools, and more. Flexible design and effective low pH liquid agent make this hood system prevalent.
The R-102 suppression system from ANSUL® uses a proprietary low pH liquid agent called ANSULEX. ANSULEX quickly extinguishes fires, cools hot surfaces, and generates a tough vapor blanket layer to prevent re-flash.
The ANSUL® R-102 system is perfect for extinguishing grease fires and protecting ventilation hoods, cooking appliances, grease filters, and hot surfaces. This system is ideal for kitchen fires. It can be installed in two different designs, overlapping and appliance-specific.
Piranha Dual Agent Fire Suppression System
The ANSUL PIRANHA dual-agent system combines wet chemical agent with a water spray to cool cooking surfaces faster, typically using fewer agent tanks than a single-agent system.

The ANSUL® Piranha dual agent was designed with restaurants in mind.
This ANSUL® fire suppression system utilizes fire suppression chemicals and water to knock fires down fast and extinguish them for good.
The Piranha dual agent system is a popular choice in fine dining and fast-food restaurants, and anywhere else you might find a commercial kitchen.
This kitchen fire suppression system combines wet chemical agent with water. The hybrid approach taken in the Piranha dual agent system outperforms single-agent wet chemical fire extinguisher systems.
As far as fire suppression systems go, it is difficult to outperform the ANSUL® Piranha dual agent system. Plus, these fire suppression systems are smaller on average and require fewer tanks, which helps businesses lower their installation costs.
ANSUL® RED Fire Suppression System
ANSUL® RED is an electronic detection system that discharges agent only where fire is detected and alerts owners to maintenance needs, working alongside R-102 and PIRANHA systems.

The RED (restaurant electronic detection) system from ANSUL® is a restaurant fire suppression system at the cutting edge of fire protection.
The RED system effectively monitors fire hazard zones.
When this restaurant fire suppression system detects a fire, it only discharges fire suppression chemicals where needed instead of covering the entire kitchen. This saves restaurants time and money cleaning cooking equipment, and other areas after chemical agents have been used.
This advanced kitchen fire suppression system allows businesses to monitor their kitchen fully and make necessary adjustments, such as reducing grease buildup before fires can start. The restaurant fire suppression system also alerts owners to required maintenance and provides easy troubleshooting support.
The RED system from ANSUL® also integrates smoothly with an R-102 and Piranha restaurant fire suppression system. Combine RED with other systems from ANSUL® for complete and total fire suppression coverage.
