Door Type Dishwashers
Door-type dishwashers—sometimes referred to as pass-through dishwashers—are a workhorse in many commercial kitchens across Canada. Designed for speed and efficiency, these upright machines are ideal for restaurants, cafeterias, and foodservice operations that process a moderate to high volume of dishware throughout the day. They feature a hood-style door that lifts upward, allowing a full dish rack to slide in and out. Once the rack is in place and the hood is closed, the cycle begins—typically lasting just a few minutes.
One of the biggest distinctions among door-type dishwashers is whether they are high-temperature or low-temperature models. High-temp dishwashers sanitize using water heated to at least 82° Celsius (180° Fahrenheit), effectively killing bacteria without the need for chemical sanitizers. These units require a booster heater—either built-in or external—which often demands a higher initial cost and more energy consumption, but delivers spotless results and faster drying due to the high heat.
In contrast, low-temp dishwashers use water at a lower temperature (typically around 60°C or 140°F) and rely on chemical sanitizers—usually chlorine-based—to meet health and safety standards. These machines are generally more energy-efficient and have a lower upfront cost since they don’t require a booster heater. However, recurring expenses for sanitizing chemicals and potential staining or odor issues may increase operating costs over time. Glassware, in particular, may benefit from high-temp models to prevent residue buildup.
Space is another factor to consider. Door-type dishwashers are often placed in dishwashing stations that include dirty and clean dish tables for an efficient workflow. Some models are corner-compatible, making them ideal for tight kitchen layouts. The typical clearance height is enough to accommodate standard dish racks and larger sheet pans, though heavy-duty models may offer even more vertical space for bulkier items like pots and trays.
Additional features can enhance the performance and convenience of your door-type dishwasher. Look for options like automatic start when the hood is closed, built-in chemical dispensers (for low-temp models), multiple wash cycles, and energy-saving modes. Some models also include built-in pumps or drain boosters to aid with water removal in facilities that lack floor-level drains. Double-wall insulation is another helpful feature that can reduce heat loss and noise levels in the kitchen.
Ultimately, choosing between high-temp and low-temp door-type dishwashers comes down to your kitchen’s priorities: energy efficiency versus speed, water temperature versus chemical usage, and long-term maintenance versus upfront costs.
