Using TEGRAS as A Tool for Kitchen Exhaust Cleaning Part 1: The Hood System

Using TEGRAS as A Tool for Kitchen Exhaust Cleaning Part 1: The Hood System

Kitchen exhaust cleaners don’t have it easy; it takes patience, passion, and willpower. Each kind of restaurant produces grease that is directly connected to what is being cooked. For instance, grease from an Asian restaurant is completely different from grease produced from an American restaurant. Asian restaurant grease can be troublesome for kitchen exhaust cleaners because the grease caramelizes from the high temperatures and sugars used during the food preparation. American restaurants on the other hand, produce a high volume of grease, that is not as sticky but, the sheer volume of grease can cause other issues. With a job like that, you certainly want the best technology to tackle any type of grease efficiently.

The TEGRAS method combines, in a single system, the four elements of the Sinner Circle: Mechanical Action (brushing), Chemical Product (degreaser), Temperature and Time (the period of time for which the foam adheres to the grease to perform its degreasing action). The TEGRAS speeds up the entire kitchen exhaust cleaning process, to the point it could be considered automated. Today, we will focus on cleaning the hood system and offer you a look at how the TEGRAS method can make this process more efficient!

The Standard Practice

Typical kitchen exhaust cleanings usually involve a standard power washing truck or van. Usually the trucks/vans have a hot water pressure system in the back and kitchen exhaust cleaners will position their vehicle somewhere on the backside of the building where they can have easy access to get inside. From there, cleaners will drag a pressure line into the building and tape off, mask off, and plastic the indoor area for spraying.

Typical hood cleanings usually involve the application of chemical, which is typically applied using a pump up sprayer. Once everything is ready, the cleaner will take the sprayer and coat the entire hood, plenum, and ducts with their chosen chemical/foam. Depending on the pump up sprayer this could involve mulitiple refills, climbing onto equipment, ladders, and multiple moves. In addition, there are different tips that can be attached to this sprayer to help it reach difficult angles and get into the tight nooks and crannies of the hood. If the cleaner does not have a one-size-fits-all tip, then they will need to change this out in-between sprays.

Once the chemical has set for the designated time, the cleaners will switch over to power washing to rinse with hot water and pressure to remove the chemical and grease. They may need to reapply the chemical until all the grease is removed and washed away. Once all the grease is gone, a high-pressure hot water rinse will finish the process.

The TEGRAS Method

Active Foam

As with the standard method, application of the chemical is fundamental to the entire process. The COMEGRAS chemical is the champion of the Tegras methodology. It is extremely effective on all types of grease, and is unlike many chemicals because it is formulated to create a heavy duty active foam. When the active foam is applied it clings to the stainless steel hood surface.  Dwell time is key. The active foam will go from white to orange in color as it breaks down the grease. The heavy duty foam will cling and pull down the grease. With adequate dwell time, light rinse will remove all remnants of grease, leaving a bare-metal clean.

Application of Chemical

The standard method of cleaning involves grabbing a pump-up sprayer and climbing up to reach the hood and apply the chemical. A manual procedure that involves refilling, pumping, and reapplying as needed. The TEGRAS method automates this procedure with the active foam generators, the IFOAM PRO and the IFOAM COMPACT. These machines were specifically designed to regulate all the degreasing foam parameters, guaranteeing the perfect adherence of the chemical to any surface. With a simple push of a button the IFOAM PRO and IFOAM COMPACT apply the active foam, COMEGRAS. There is less waste than other chemicals that often require reapplication. The active foam generators apply the perfect composition of chemical.

Rinsing the Hood System

That standard method of cleaning involves the use of a powerwash truck. KEC’s will feed the hose to the hood system to hot pressure wash the surface. With the TEGRAS method, no additional equipment is needed to clean the hood. The active foam generators, the IFOAM PRO and IFOAM COMPACT , provide everything you need to clean hoods, plenums, and exhaust fans in a single unit. These units switch from chemical application to rinse mode with a simple push of a button. The COMEGRAS chemical does most of the work, the hood requires only a light rinse. These machines are ideal for the most demanding hood cleaning!

Conclusion

The TEGRAS method of kitchen exhaust cleaning is the perfect way to get back more time and money for your company. With the time saved, more restaurants can be cleaned, helping to make your business more money.

In a commercial kitchen, the focus is often on what’s in plain sight: clean counters, properly functioning appliances, and seamless service. But hidden just above the kitchen line — in the ductwork of the exhaust system — are critical risks that can’t afford to be ignored. One of the most significant yet overlooked contributors to kitchen fires is poor duct access. Without proper access, routine cleaning becomes incomplete or impossible, allowing dangerous grease buildup to persist unchecked. These hazards can ignite in a flash, threatening lives, destroying property, and leading to costly downtime. In addition, failure to maintain accessible duct systems can violate fire codes and invalidate insurance coverage. If your kitchen exhaust system isn’t fully accessible, the consequences can be far more than just inconvenient — they can be catastrophic. Why Duct Access is a Fire Safety Essential Grease, fats, and oils naturally accumulate inside the ducts of every kitchen exhaust system. Over time, these residues form a flammable layer that can ignite if exposed to high heat or an errant spark. Restricted airflow from clogged or partially blocked ducts can also reduce the efficiency of your system, driving up energy use and maintenance needs. Recognizing these risks, the National Fire Protection Association (NFPA) established clear standards in NFPA 96, which requires access doors to be installed every 12 feet and at every duct turn. These doors provide critical entry points for cleaning crews to properly inspect and remove grease deposits. Without them, even the most skilled technicians can’t reach key areas — leaving behind fire hazards that remain out of sight and out of reach. A Smarter Solution: Omni’s Access Armor™ Meeting NFPA requirements is just the beginning. At Omni Containment Systems, we’ve designed our Access Armor™ doors to go beyond code — combining ease of use with exceptional fire resistance to keep kitchens safer and maintenance teams more efficient. Unlike traditional access doors that require tools or involve loose parts, Access Armor™ features a Cam-Lock mechanism that secures the door without extra hardware. This toolless design means faster access for maintenance and no risk of misplacing small pieces during cleanings. It’s a system built for the fast pace and high standards of modern commercial kitchens. The construction of Access Armor™ is just as impressive. These octagon-shaped doors are fire-rated up to 2,300°F, exceeding the NFPA 96 standard of 1,800°F, and they can withstand temperatures of up to 2,700°F. This enhanced durability is crucial not only for safety but also for minimizing long-term maintenance and reducing potential liability. Cleaning Plans That Reinforce Safety While access doors are foundational, a comprehensive cleaning and inspection plan is equally important. Grease buildup inside ducts should never exceed 0.002 inches (50 microns). Measuring this accurately — and consistently — helps you schedule cleaning before that threshold is crossed. Omni makes this easy with our stainless-steel grease comb , a simple but powerful tool that allows your team to check grease depth on the spot. This proactive approach ensures you're never left guessing whether it's time for professional cleaning. For most commercial kitchens, professional duct cleanings are recommended every six to twelve months, depending on cooking volume and equipment type. In addition, components like filters and containment tray pads should be inspected and replaced every three to six months to ensure optimal performance and containment of grease particles before they reach the ductwork. By combining hardware, monitoring tools, and a regular service cadence, you not only improve fire safety but also increase the efficiency and lifespan of your entire exhaust system. The Cost of Noncompliance — And the Power of Prevention Neglecting duct access doesn’t just increase fire risk — it can lead to code violations, fines, and higher insurance premiums. In some cases, an insurance claim following a fire may be denied if the system was found to be noncompliant or improperly maintained. Investing in the right equipment and practices today can prevent costly consequences tomorrow. Omni Containment Systems offers a full suite of solutions designed to make compliance easy and intuitive. Our products are built to exceed industry standards, giving your team the tools they need to perform safe, thorough maintenance on schedule. Bringing the Hidden Risks Into View In the world of kitchen safety, what you don’t see can hurt you. Poor duct access allows grease to build silently, turning your exhaust system into a ticking time bomb. But with the right access doors, cleaning tools, and maintenance strategy, you can eliminate those risks before they become real threats. Omni Containment Systems provides everything you need to take control of your kitchen exhaust safety. With Access Armor™, grease monitoring tools, and expert guidance, you can ensure that your ducts are clean, your kitchen is compliant, and your business is protected — from the inside out.

The essential role of nfpa 96 compliance in managing fog risks in restaurants
14 January 2025
Compliance with the NFPA 96 Standard is a critical step in managing the risks associated with fats, oils, and grease (FOG) in restaurant operations. This standard, which addresses the design, installation, operation, and maintenance of commercial kitchen ventilation systems and grease removal devices, serves as a foundational guideline. However, it does not comprehensively cover every aspect of FOG management. For instance, when grease escapes through kitchen exhaust systems or is improperly disposed of, it can create significant environmental challenges.
