Cartridge Heater Advantages

Multicircuits: 3/4″ diameter RAMARODs can be provided with independent heat zones thru multicircuit or 3 phase resistance wire windings; these heaters permit uniform heat along the entire length of the heater where heat transfer rates must vary between specific heated areas. Consult RAMA for minimum length requirements.
Profiled Heat: RAMAROD and EDM heaters can be manufactured with a shaped profile heat distribution to balance out heat applied along the length of the heater.
Thermostats: Various thermostats meeting different sensitivities can be incorporated into and made an integral part of RAMAs cartridge heaters to control or act as a safety monitor against excessive temperature.
Moisture Resistant Barriers: In addition to the Teflon seal type heaters, which will withstand operating temperatures up to 300°E various epoxy compounds can be supplied at the leadwire end for heater operation up to 450:F Consult factory for detailed information.
Other Accessories: Cartridge heaters can be supplied with grounded, twist-lock as well as UL-listed, dead front (hospital grade) electrical plugs. Post terminal and terminal boxes for protection of electrical connectors are available.
