Buffets and off-site caterers often rely on potentially environmentally damaging solutions like gel-based chafing fuel, but the 'Nemco Drop In Warmer' offers equally effective results while using less energy, creating less waste, and engendering a safer eating environment. The heating surfaces use induction technology that eliminates an open flame entirely while only drawing a minimal amount of power.
Induction warming is unique from other styles in that it isn't actually the surface itself heating the food. The Nemco Drop In Warmer has an electromagnetic coil beneath a sheet of impact resistant glass, and even when turned on, that surface will be cool to the touch. The heating comes when the surface contacts an induction-compatible pan or other food vessel (common materials like cast iron, stainless steel, and induction-ready cast aluminum qualify). When those materials react with the electromagnet, the materials themselves heat up — as opposed to the surface. This ultimately creates a safer dining space.
