They are capable to generate temperatures and specific heat that are higher thant the temperatures and specific heat generated by mica insulated heater. The type of construction consists of a helically wound resistance, coil made from nickel-chrome wire, installed in ceramic insulating bricks, forming the mat. the ceramic mat is installed in a metallic housing (stainless-steel or aluminium sheet) made with serrated edges, which consents maximum flexibility and ease of application. We can design special products with double insulation for applications requiring low external temperatures or needing electrical energy saving.
