Guide to Warewashing & Janitorial Equipment
Door-type dishmachines are available in both high-temperature and low-temperature
versions. High-temp models sanitize using a final rinse temperature of 180°F (82°C)
and sometimes require a booster heater to reach proper sanitization levels. These
models will almost always need to be installed under a Type 2 condensate hood due
to the volume of steam generated when the door is lifted at the end of a cycle unless
you have a Ventless Type unit. On the other hand, low-temp units rely on chemical
sanitizers awnd typically operate at lower rinse temperatures (120°F–140°F), which
can reduce utility costs and eliminate the need for a booster heater — but may require
careful monitoring of chemical levels and water hardness to maintain edectiveness.
Because these machines
are designed to clean a
wide variety of wares —
including plates, bowls,
cutlery, trays, and even
small cookware — they offer
a degree of versatility not
found in more specialized
equipment. Many modern
models feature auto-
fill functions, digital
temperature readouts, and
multiple cycle settings for
light or heavily soiled racks.
It is important to note that
some of the Door-Type
units often do not come
equipped with detergent/chemical pumps and need be installed after by a 3rd party
chemical supplier. Some machines do offer pre-installed pumps and hoses - Contact
your local RED Dealer to discuss the options for these units.
Another advantage of the door-type format is its ease of maintenance and cleaning.
Wash arms, filters, and scrap trays are typically accessible without tools, and the open
design allows for quick inspections and internal rinsing during and after shifts. For
operators managing consistent, moderate dish loads throughout the day, this type of
machine strikes a balance between performance, space-efficiency, and ease of use.
Door-type dishwashers are best suited for operations serving between 100 and 400
meals per day where peak- time efficiency is crucial, but a full conveyor system would
be excessive. Their ability to scale up quickly during rushes, while remaining compact
and easy to service, has made them a mainstay in kitchens across Canada.
