Cartridge Heaters with a unique, patented split-sheath design
These heaters expand when energised to maximise heat transfer through greater contact with the wall of the bore. Better heat transfer means less power is consumed to maintain the set point temperature, reducing operating costs.
The split-sheath design and highly specialised manufacturing techniques of the Watt-Flex cartridge heater reduces the total cost of process heating by an average of 40% more than other heaters.
The construction eliminates ceramic cores typically found in conventional cartridge heaters. Dalton has developed and highly-specialised manufacturing techniques to compact high-grade MgO dielectric to near its maximum density around the heater coil. This increases dielectric strength and heat transfer away from the coil, resulting in significantly longer heater life.
The videos below help to explain all of the features and benefits.
They last up to 5 times longer than conventional heaters, with less downtime for heater replacements and lower maintenance costs. The heaters contract when de-energised, eliminating bore seizure and the need for expensive drill-outs.
