Mica-TF® Thick Film Mica-Based Heater

Our unique thick-film heater element is printed directly onto mica resulting in a thin, lightweight, low-profile, precise and uniform heating solution. The Mica-TF heaters can be attached to a surface to act as an efficient conductive heater or mounted as an effective radiant heater.

Mica solutions are featured in food warming & cooking, and holding devices, enclosure heaters, radiant comfort heaters, LCD warmers and specialty industrial applications.

Our Mica-TF technology is comprised of resistive and conductive thick film paste that we screen-print directly on mica to create an advanced thermal component.

The thick film heating element is printed directly onto mica, producing reliable, uniform, cost-effective heating solutions.

Case Study – Leading North American Retailer

Residential ovenA North American retailer needed Datec’s leading-edge technology to meet performance and reliability requirements.

The Project

The client required a hot food display case that could keep food at the required safe holding temperature.

At the time, the client was using standard industry technology, but it was unreliable and inconsistent, resulting in hot and cold spots and compromised food.

As the years went on, the unit deteriorated from repeated use, and the temperature readings were no longer accurate.

The client needed a heating solution that was reliable, consistent, uniform, and could stand the test of time.

The Solution

Using our expertise in design, materials and printing, Datec created uniform heating components that would heat-up quickly and maintain its set temperature for as long as required.

The heating element created is proven 99.9% reliable over 2 million operating days.
