The right temperature matters to make passengers feel comfortable on the move. Different types of vehicles pose different challenges for heating within the car. That's why at WITSTO, we investigate the heating environment before customizing suitable heating elements for you.
Besides, we're certified by IRIS (International Railway Industry Standard), which means that our heating elements are qualified for railway use.

In appliances whose functioning is based on heat generation, like oven and printer, electrically powered heating systems are at the heart. The right selection of the heating elements affect the reliability, performance, and durability of the appliance
At WITSTO, we offer a wide range of heating elements specially-designed for small domestic appliances, especially tubular heaters which are custom-formed in various shapes for specific requirements.
Machinery industry poses great challenges for heating like high working temperature and the demanding heating environment.
Our heating elements for the machinery industry take all these into considerations. Anti-scale coating/ explosive-proof cover can be added to our immersion heater for water or oil tank heating. And our cartridge machines can be accurately crafted to fit your mold size & the exact high temperature.

Accuracy is one of the most crucial factors in making medical equipment. So there are strict requirements for electric heating elements like exact dimensions, minimum tolerance & high insulation.
With our state-of-the-art machines, we can make heating tubes to the exact size you need no matter it’s 4mm or 12mm. And the lead wire & terminal of each heating element is customized to make a perfect fit with your medical equipment.
Check out how we solve their challenges with our expertise.
CRH3 high-speed train we served runs in the area where the weather is extremely cold. The big heating challenges are to prevent condensation, make the inside of the train feel warm & passengers comfortable.
After investigating the extreme weather condition, our engineer came up with a tubular heater featuring j ust the right working temperature. Fins were added to the element, making the heat distributed evenly & passengers feel more comfortable.
The heating medium is oil which poses high requirements for consistent heat distribution. The explosive nature of oil also asks for special protection for the element. And each product should meet the standard of 10,000-hour lifetime.
After analyzing the working environment, our engineers came up with a cartridge heater featuring evenly-distributed & highly-compressed MgO powder for uniform heating. And every product is tested with a machine to ensure 10,000-hour lifetime. For all the products we sent, the failure rate is lower than 2%.
Scale build-up in the water tank greatly affects the heat transfer performance. Accumulated high temperature caused burnout of resistance wire & breakdown of the whole element.
After studying the heating environment in the water tank, we developed an immersion heater made of corrosion-resistant Incoloy 800 alloy, the surface of which is covered with an anti-scale coating. And there's no burnout issue after more than 1-year use.
Cartridge heater with a tiny tube diameter is required to fit into the medical equipment, and no tolerance is allowed in the situation. 10,000-hour lifetime is a must for all heating elements.
By trial & error, our engineer finally developed a cartridge element whose diameter is as accurate as 0.5mm. And all the heaters are tested to meet the 10,000-hour lifetime standards requested.
