Description
Description
The Olympic Warmette is a large-capacity, free-standing warming cabinet. It is
available in two sizes with the option of convenient see-through doors on the front
and back for either size.
The Warmette has a fully-enclosed, recirculating air system that warms blankets
and bottles quickly and uniformly. Forced-air distributes heat evenly throughout
the entire cabinet, so supplies are heated rapidly no matter where they are placed.
Mesh shelves allow air to move under and around supplies.
