High Temp Commercial Dishwasher: Does it Require a Hood?

If you're in the market for a commercial dishwasher, you may be wondering if a high-temperature dishwasher requires a hood. This is an important question to consider, as regulations regarding ventilation and air quality in commercial kitchens can be strict. In this article, you'll find all the information you need about whether a high-temperature commercial dishwasher requires a hood.

Before diving into the specifics of whether or not a high-temperature commercial dishwasher requires a hood, it's important to understand what a hood does. A hood is a ventilation system that helps to remove steam, smoke, and other airborne particles from the air in a commercial kitchen. This is important not only for the comfort of those working in the kitchen but also for the health and safety of everyone in the building.

Now that you have a basic understanding of what a hood is and why it's important, let's take a closer look at whether or not a high-temperature commercial dishwasher requires one.

What is a High Temp Commercial Dishwasher?

A high temp commercial dishwasher is a type of commercial dishwasher that uses high-temperature water to sanitize dishes, glassware, and utensils. These dishwashers are designed to remove tough stains, grease, and bacteria from dishes, which is essential in a commercial kitchen. High temp commercial dishwashers use a combination of high-temperature water and detergent to clean and sanitize dishes. The high-temperature water is heated to at least 180°F (82°C) and is used to sanitize the dishes during the final rinse cycle.

High temp commercial dishwashers are typically more expensive than low temp commercial dishwashers, but they are also more effective in removing tough stains and bacteria. They are also more energy-efficient than low temp commercial dishwashers, as they do not require a separate heating element to heat the water. Instead, they use a booster heater to heat the water to the required temperature.

High temp commercial dishwashers are essential equipment in any commercial kitchen. They are designed to handle high volumes of dishes and utensils and are built to withstand the rigors of daily use. They are available in a variety of sizes and configurations to meet the needs of any commercial kitchen.

What is a Hood?

A hood is an essential component in a commercial kitchen that is used to remove excess heat, steam, and smoke generated by cooking equipment. Specifically, Type II hoods are used over dishwashers and appliances to remove the excess heat generated by dishwasher machines.

Type II hoods, also known as condensate hoods, remove the extra heat from the air, creating a comfortable kitchen environment. They are designed to capture and remove steam and heat from the dishwasher and exhaust it outside the building. This is important for the comfort of the kitchen staff and the safety of the building and its occupants.

It is important to note that not all hoods are created equal. Hood systems must meet strict guidelines and regulations to ensure they are effective and safe. For example, any hood in the kitchen should be made of steel with a minimum thickness of 0.0466 inches or stainless steel with a minimum thickness of 0.0335 inches. Each hood should also include a label indicating the minimum exhaust flow rate in CFM (cubic feet per minute) per linear foot.

Overall, hoods are an important component in any commercial kitchen, and Type II hoods are necessary to remove excess heat generated by dishwasher machines.

Why is a Hood Necessary for a High Temp Commercial Dishwasher?

High-temperature commercial dishwashers are known for removing tough food soils and sanitizing dishes effectively. However, they also produce a significant amount of steam, which can create a hazardous environment for employees and customers. In this section, we will explore why a hood is necessary for a high temp commercial dishwasher in terms of safety, health, and fire regulations.

Safety Regulations

According to safety regulations, a commercial kitchen must maintain a safe working environment for its employees. A high temp commercial dishwasher produces steam that can cause burns, slips, and falls. A hood is necessary to capture the steam and prevent it from escaping into the kitchen, reducing the risk of accidents and injuries.

Health Regulations

Health regulations require commercial kitchens to maintain a clean and sanitary environment. A high temp commercial dishwasher uses hot water to sanitize dishes, which produces steam that can condense on surfaces and create a breeding ground for bacteria and mold. A hood is necessary to remove the steam and prevent the growth of harmful microorganisms.

Fire Regulations

Fire regulations require commercial kitchens to have a fire suppression system in place to prevent fires and protect employees and customers. A high temp commercial dishwasher produces steam that can mix with grease and other flammable substances in the kitchen, increasing the risk of fire. A hood is necessary to capture the steam and prevent it from igniting, reducing the risk of fire and damage to the kitchen.

In conclusion, a hood is necessary for a high temp commercial dishwasher to comply with safety, health, and fire regulations. It helps to create a safe, clean, and sanitary environment for employees and customers while reducing the risk of accidents, injuries, and fires.

How to Choose the Right Hood for Your High-Temp Commercial Dishwasher

Size

When selecting a hood for your high temp commercial dishwasher, size is an important factor to consider. The hood should be large enough to cover the dishwasher and any other appliances that generate heat in the kitchen. The size of the hood will depend on the size of the dishwasher and the kitchen. It is recommended to consult with a professional to determine the appropriate size for your kitchen.

Type

There are two types of hoods that can be used with high temp commercial dishwashers: Type I and Type II. Type I hoods are used for appliances that produce grease-laden vapors, such as grills and fryers. Type II hoods, such as dishwashers, are used for appliances that produce steam and heat. It is important to choose the correct type of hood to ensure proper ventilation in the kitchen.

Installation

Proper installation of the hood is crucial for effective ventilation in the kitchen. The hood should be installed at the correct height above the dishwasher and other appliances. The exhaust ducts should be properly sized and installed to ensure that the air is properly vented outside. It is recommended to have a professional install the hood to ensure that it is installed correctly. In summary, when choosing a hood for your high temp commercial dishwasher, it is important to consider the hood's size, type, and installation. Proper ventilation is crucial for a comfortable and safe kitchen environment. Consulting with a professional can help ensure that the correct hood is chosen and installed correctly.

Conclusion

After analyzing the information gathered, it can be concluded that a high-temp commercial dishwasher requires a hood. The hood is necessary to remove the steam or water vapor emitted when opening the door of the dishwasher. The hood also helps to remove heat and moisture from the kitchen atmosphere.

It is important to note that not all commercial dishwashers require a hood. For instance, a commercial undercounter dishwasher will not require a dishwasher hood. However, a door-type dishwasher will require a hood since it is a high-capacity unit that produces a large amount of steam.

Additionally, high-temp dishwashers have condensate hoods because they use heat to sanitize dishes at 150 to 160 degrees Fahrenheit. On the other hand, low-temp dishwashers use chemical sanitizers with temperatures between 120 and 140 degrees Fahrenheit, and they do not require a hood.

It is crucial for restaurant owners and operators to understand the regulations and requirements for commercial dishwashers in their area. This will ensure they comply with local codes and regulations and avoid potential fines or penalties.

Overall, investing in a high-quality commercial dishwasher with the appropriate hood or ventilation system is essential for any restaurant or food service establishment. It ensures efficient cleaning and sanitation of dishes and helps maintain a safe and healthy kitchen environment for employees and customers.
