Hopper Heaters

Hopper Heating Pad

Celsun heating pads are designed to cover the maximum area of the vessel. Hence it gives uniform heat transfer throughout the surface, avoiding any hot-spot or carbonization of the content. Temperature is uniform and can easily be controlled. The elements are designed to work in black – heat region and closely follow the vessel surface temperature. Our modular design provides the:

• Easiest and lowest cost-of-installation

• Most cost-effective and energy-efficient heat possible   across a large    surface area

Construction details:

The electrical heating pad consists of nichrome wire heating elements insulated with two braids of glass-fiber yarn and impregnated with class f varnish. The element is spread over closely woven glass cloth carrier at a uniform pitch and again sandwiched between two layers of glass cloth.

The lead wires, comprising of fiberglass and Teflon insulated copper wire, are taken out from one side. Eyelets are provided for fixing the pads on vessel. Tying laces may also be provided for smaller size.

Technical specifications:

Maximum safe temperature         270oc
Maximum power density

3.0 kw/sq. Mtr.

Working Voltage    230v single phase ac
