Are Round Grease Ducts Better Than Rectangular Grease Ducts?
Your commercial kitchen grease duct design decisions can have a significant impact on safety and comfort in your facility. You can make it easier or more difficult depending on the restaurant hood system that you choose. Your system will run more efficiently and effectively if you have the right components. They can also impact your ability to maintain and inspect your system.
Round grease ducts are more efficient than rectangular ones. This is something you may be wondering about when designing your duct system. Let's compare the performance of rectangular and round grease-duct components in certain key areas to help you choose the best duct system for you.
Safety and Cleaning
Each restaurant is unique, but they all share one thing: grease and smoke. Safety is the number one concern when you're installing or replacing ductwork in commercial kitchens. Grease buildup is one of the best ways you can make your ventilation system safer.
How does round grease ducts and rectangle ducts compare in terms of safety and cleaning?
Round ducts are free from corners and have a smaller surface area than rectangular ducts. Round ducts are simpler to clean and have less buildup.
Grease buildup in a round conduit will result in the grease settling in the lower section of the duct. Grease can be easily removed and accessed with the round duct. Round ducts won't hold grease as well, and popular hood cleaning tools like spin-brushes work better in them.
Contract ducts have a rectangular shape that allows grease effluent, food particles, and creosote for solid fuel cooking to accumulate on large flat surfaces as well as corners and crevices. This makes cleaning more difficult and can lead to grease duct fires, which could be dangerous for your entire building.
No matter if you have rectangular or round ductwork, grease duct access doors are required. The doors can be installed on a flat or round surface, so make sure to know the type of duct that you are adding access to.
Efficiency and function
Your ventilation system's efficiency and functionality are greatly affected by air flow and static pressure. An inefficient system can have a significant impact on safety and cost. Inefficient systems will not be capable of properly exhausting grease-laden air. Inefficient systems will let grease collect more easily on the surfaces of the conduit, instead of being pulled through the system to exhaust it. Rectangular ducts are more efficient than ducts.
Efficiency:
Round ducts are able to flow more air and have less friction than rectangular ducts. Because air flows through a circular pattern, this is because it has a circular shape. The airflow in rectangular ducts is always clogged with flat surfaces, which causes turbulence that impairs exhaust system efficiency. This causes grease buildup in corners which can be difficult to clean. Noise is also increased. You can get the highest quality grease ducts in all shapes at GIS insulation at affordable prices. They are made up of premium quality and high strength material that lasts long and easy to clean.
