For over 100 years, Dalton Electric Heating Co., Inc. has been at the forefront of precision-engineered heating solutions for industrial applications. Our Watt-Flex® Cartridge Heaters and Diff-Therm® Platen Heaters set the industry standard for unmatched temperature control, efficiency, and reliability, serving critical sectors such as packaging, plastics, composites, aerospace, automotive, and more.

At Dalton, we don’t just manufacture heaters, we engineer customized thermal solutions that integrate seamlessly into our customers’ equipment, optimizing performance and longevity. Our team of expert engineers collaborate closely with customers to develop heating solutions that enhance process control, energy efficiency, and precision at every level.

In high-throughput packaging operations, where thermal precision directly affects seal integrity, cycle time, and material performance, conventional cartridge heaters remain standard but often fall short. Dalton’s Watt-Flex split sheath heaters are engineered to expand against the bore wall during operation, providing superior thermal conductivity which enables faster, more uniform heating. This enhances process reliability, seal consistency, and production efficiency, leading to increases in product quality and throughput.
