These special purpose cartridges are designed to provide the optimal physical, thermal and electrical properties for the precise application for which they are designed. Thermal Corporation cartridge heaters can be used for many heating applications, but are usually used to heat metal blocks by inserting holes into the metal. When used in this application, the main factors influencing heating life are the water density on the heating surface, the hole adjustment and the operating temperature.
If the application conditions result in continuous lead flexing, complete the cartridge heating cables in a terminal block that moves with the heated mounting. The flex is transferred to the extension cables that can be economically replaced. Test recommendations: It is proposed to perform tests under simulated operating conditions when equipment manufacturers design new products. Cartridge heaters of the correct physical size are used on a variable transformer until the heat output is at the correct level. Voltage and current measurements are then performed and the required power classification is calculated. Heating elements with the correct power value are required for the designed product.
The power and cables of the thermocouple sensor are placed outside the sheath . Many types of thermocouple cartridge heaters have been designed for specific applications. The installation of a square cartridge heater simplifies wiring and installation and optimizes performance in a wide range of applications for solid, liquid and gas heating. Mica Bands Large diameter cartridge heating: for medium and low watt density applications. Compact refractory insulation ensures excellent heat transfer to the stainless steel cover of the heavy wall. This means that the resistance cable works at a lower temperature than competing units with loose filling insulation; The result is a much longer life.
Depending on the type of application, different metal alloys are used as very acidic or corrosive environments. The most common types of pods are 304 stainless steel, 316 stainless steel and Incoloy 800. Thermal Corporation’s Cartridge heaters are high temperature stamping units made of magnesium oxide insulation. Each Thermal Corporation cartridge heater is a premium unit with a colorless pod that offers higher temperature and increased chemical corrosion resistance.
For specific applications such as radiators and towel dryers, there are double insulated cartridge heaters. Self-regulated cartridges are ideal for defrosting and evaporators and bolt heaters are typically used for mechanical assemblies. Before you decide to buy a block heater, it is crucial that you know the different types of block heaters. There are five types you can pass on: inline stoves, freezer push warmers, cartridge heaters, drain box heaters and oil container heaters. Let’s briefly summarize each type of block heating and the installation process.
