The Plates Warmer are manufactured from premium quality raw components, we also offer plate warmed that hava the ability to warm upto 15 plates. Ideal for party time, they have a heat storing core material for releasing heat to food serving supported there on dish ware over an extended period of time. The heat storing material comprises beads of synthetic petroleum wax which are compressed to form a solid core having inwardly concave top and bottom surfaces and to expel air from the core. When the plate warmer is heated, the core expands outwardly against the concave walls of the outer plate members and the walls assume a substantially flat configuration wherein the cavity is enlarged to accommodate the expanded core material.
