Thick Film Heaters for Food Devices: Efficient Heating for Modern Food Equipment

What is a Thick Film Heater?

A thick film heater is a type of printed heating element created by screen-printing conductive and resistive pastes onto a ceramic, stainless steel, or aluminum substrate. This technology creates a thin, flat heater capable of providing fast, uniform heating with precise temperature control. Thick film heaters can be customized in shape, size, and power density to fit the specific thermal requirements of food service and processing equipment.

Traditional heating methods often struggle with slow response times, uneven heat distribution, or excessive energy consumption. In response, thick film heaters have emerged as a compact, efficient, and customizable heating solution for a wide range of food devices, from warming trays to commercial coffee machines and advanced cooking appliances. Here is a comparison between thick film heater and traditional heating methods:

‌Company Location‌: Germany

Application‌: Instant hot water dispensers (commercial & household) ‌

Field‌: Smart kitchen appliances ‌

Service‌: Customized heating solutions for liquid temperature control

The customer, a prominent manufacturer of water dispensers, faced challenges with inefficient heating and energy consumption. Their existing heating solution led to uneven temperature distribution and high energy usage. The client needed a low-voltage, compact, and energy-efficient heating solution that could work within a broad temperature range of -20°C to 100°C without compromising performance.

1. Communicated closely with the customer to identify key requirements like heating performance, size limitations, and low-voltage operation, ensuring our solution aligned with their needs.
2. Ensured even heat distribution to maintain stable water temperatures and designed the heater to operate reliably within the -20°C to 100°C range.
3. We chose thick-film heating technology for low-voltage efficiency, reducing energy consumption and cutting costs for the customer.
4. We worked closely with the customer throughout the design and testing process, making necessary adjustments to meet their expectations.
