DeltaSense announced that it is distributing Calesco's flexible foil heaters that feature electrical heating circuit sandwiched between one or more insulation layers.

Quick to heat up, they provide immediate heat transfer to very precise locations, with operating voltages varying between 1V and 700V AC/DC and temperatures up to 600°C. They can be supplied in customised shapes and sizes to suit the precise application, and can even have multiple voltages and temperature zones on the same element.

The circuit material can be a resistance heating alloy such as copper, brass or aluminium, or it can be carbon or silver based. Insulation layer materials include PVC, polyester, silicone rubber and mica.

Elements can be designed with a varying output to compensate for heat loss at the edges, and temperature sensors can be added in any location on the same level as the heating circuit.
