THE LEADERS IN CARTRIDGE PROCESS HEATING TECHNOLOGY

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 aerospace, automotive, composites, plastic, and more.

WATT-FLEX®

PROCESS HEAT PRECISELY DELIVERED

Watt-Flex® Split-Sheath Cartridge Heaters make full contact with the bore wall for fast, efficient conductive heat transfer and uniform temperature distribution. Watt-Flex® helps manufacturers:

  • Accelerate equipment cycle time and increase throughput
  • Deliver more consistent part quality with uniform temperature distribution across the full heating zone
  • Improve yield and cut material waste in thermally sensitive production
  • Prevent bore seizure and minimize unplanned downtime
  • Lower total cost of heating and improve return on investment 

DIFF-THERM®

VACUUM DIFFUSION PUMP HEATERS

Diff-Therm® vacuum diffusion pump heaters use high-quality tubular heating elements swaged into grey iron castings to deliver long life, even heat distribution, and reliable power for high-vacuum processes.

THE DALTON DIFFERENCE

Dalton Electric’s Watt-Flex cartridge heaters are engineered as a performance upgrade for industrial process heating, not a commodity replacement. By expanding outward when energized and contracting when cool, Watt-Flex® maintains full sheath-to-bore contact for efficient conductive heat transfer and easy removal.

This design, combined with a continuous axial heating coil and highly compacted magnesium oxide insulation, delivers higher throughput, improved finished part quality, and a lower total cost of heating.
