Many restaurants choose to use low temperature dishwashers because they offer benefits that all temperature dishwashers do not. This makes them a commonly used appliance for those within the foodservice industry. For the most part, low temperature dishwashers offer a lower upfront and operating cost. They are typically cheaper to purchase and install than many high-temp models, especially since they do not need a booster heater to operate. They also save on energy, since they heat water to only about 120–140°F. This is compared to 180°F+ in high-temp machines. So if you are operating on a budget, then a low temperature dishwasher is a smart move.
On top of budget savings, a low temperature dishwasher is gentler on plasticware, such as plastic trays, cups, and utensils. All are less likely to warp or melt in lower temperatures. This is another area where a low temperature dishwasher thrives, as it is perfect for use in cafés, delis, schools, and casual dining where reusable plastic items are frequently washed. And since the temperatures are lower, they effectively use chemical sanitizers in the final rinse instead of heat in order to meet food safety standards. As long as the chemical concentration is properly monitored, low-temp machines safely sanitize dishes per local health codes. However, these appliances are not ideal for greasy cookware. Without the high heat, greasy pans may require pre-scrubbing or extra cleaning. Check out our kitchen degreasers for help in that area.
Lastly, low temperature dishwashers can process dishes quickly and efficiently. This makes them suitable for restaurants that need to turn over tableware fast without high utility costs. If you are looking for a low temperature dishwasher to save on upfront costs with long-term energy savings, then check out the restaurant dishwashers in our inventory.
Restaurants use low-temp dishwashers because they are cost-effective, safe, and efficient, especially when paired with proper low-temp detergents and sanitizing practices. Read on to learn more about the benefits and reasons why restaurants choose to use certain detergents that work best with low temperature dishwashers.
Using low-temperature dishwasher detergents offers users several key benefits, particularly in terms of energy efficiency, safety, and environmental impact. Here’s a breakdown of those benefits.
You save on energy by lowering water heating costs. Traditional dishwashers often rely on hot water (140°F or higher). However, low-temp dishwashers are designed to work effectively at around 120°F or lower, which reduces the need for water heating. And in general there is a reduced overall energy consumption. This leads to less energy used per wash cycle, which will lower utility bills.
Low temperature dishwashers and detergents put less stress on equipment. The lower temperatures cause less thermal wear and tear on internal components, gaskets, and seals, which potentially extends the life of the dishwasher.
Low temperature dishwashers are typically safer to use as they are safer for plastics and have a lower burn risk. Low-temp detergents are gentler and reduce the risk of melting or warping plastic dishware, which also keeps that dishware in good condition for longer. And in commercial kitchens, having lower temperatures helps decrease the risk of scalding injuries to workers.
These types of dishwashers have a lower operational cost. This is especially true for commercial kitchens running multiple cycles per day. Using low-temp detergents reduces energy and maintenance expenses over time, making them a more cost-efficient option compared to their high-temperature counterparts.
Low-temperature dishwashers are eco-friendly as they offer reduced greenhouse gas emissions. The lower energy demand means less fuel burned for electricity generation. On top of that, there are more eco-friendly formulas for the detergents, which align with sustainable practices. Many of these low-temp detergents use enzymes that break down food residues effectively at lower temperatures. Ultimately ensuring clean results without needing intense heat.
