NOTE: If water is in the unit, it should be drained prior to switching the set point. Pans should be removed to help decrease the length of time it takes for a well to reach the new set point.

Yes, the Duke HotColdFreeze™ provides versatility and flexibility for your operation by allowing you to operate any well in hot, cold, or freeze modes. Mix and match modes in any combination for ultimate menu flexibility. Example:

• Hot, Hot, Cold • Cold, Freeze, Hot • Hot, Cold, Cold • Hot,Cold, Freeze
• Freeze, Hot, Hot • All Hot • All Cold • All Freeze

The combinations are endless.

Always be sure to drain the water before switching a well containing water from one mode to another.

There is no transfer between the wells. Hot says hot, cold stays cold, frozen stays frozen.

Wet heat is notorious for many issues that arise with water in a well, such as rust, clogs in the drain line, and safety concerns for the operator. Dry heat keeps moist foods, moist and delicious without the use of water eliminating common issues and concerns with the use of water.

No, moist products hold just as well with our dry heat technology as they do with wet heat in our wells. Using dry heat eliminates the extra work and safety concerns associated with filling wells with water. Using water does not provide any advantage to the operator.

There is not an autofill option at this time. We will evaluate this as a future feature depending upon demand.

No, the Duke HCF does not have an autofill connection on its own. However, a fill faucet can be added to the counter next to one side of the unit.

Yes. A “no drain, dry heat only option” is available for all DukeHotColdFreeze models. The “no drain, dry heat only option” allows for the use of DukeHotColdFreeze Drop-Ins in water conservation municipalities, where no floor drains and water connections are available and as an option in mobile carts and counters. The no drain, dry heat only option lowers installation costs and simplifies service due to lack of drain manifolds and water connections. This option comes with a removeable non-stick liner.

Revit models available in KCL and AutoQuotes. 2D CAD drawings also being added.
