Flat heating elements

Use:
Flat heating elements are used for the same purpose as tube heaters – in industries where no extreme temperatures are required. Dimensions of the plate heaters can be adapted to the requirements of the buyers. Maximum power is 6 W/cm2.

Structure:
Housings of flat heating elements are made of either brass, expanded or white metal plates. Heaters without housing are available as well. Thickness of the plate ranges from 2.5 to 10 mm. The heating wire is flat, made of high-alloy and highly resistant metal. It is coiled around a core from micanite or natural mica. Micanite is heat resistant and endure temperatures up to 800 °C.

Connection:
Electrical connectors are made either of copper or high-alloy wire, insulated by silicone or glass fibres and fixed by screws or by a mechanical junction. The connector is made in any place on the plate indicated by the buyer.

Orders:
All of the main characteristics of a desired heater (voltage, power, length, width, performance and place of electrical connection) have to be specified in the order. Add a sketch or a specimen, if possible. When ordering heaters with wire connection that are in the same level with the flat part of the heater, one can use a code as explained here.

Example:
You wish to order a heater – voltage 110 V, power 200 W, width 30 mm, length 200 mm, connector length 400 mm. Code number: P.110.200.30.200, l is 400 mm.
