When you need a heater for your house or office, you may need to look for a reliable heating element manufacturer. In the United States, the Rama Corporation is one of the top heating element manufacturers. However, there are many other options available. The most important thing to consider is the durability of the product. In general, the heating elements manufactured by Rama Corporation are quite durable and are of good quality. The company’s products are trusted by many, including Rama Corporation.
A Good Heating Element Is Not Only Durable, But It Also Offers High Temperature Resistance
The most common problem facing a cartridge heater is contamination. Specifically, the termination area is susceptible to process-related, machine-wash-down, and oil-related contamination. The heating element manufacturer needs to be aware of the environment that the unit will be used in, and choose a product that can withstand the conditions. Depending on the power level of the heating element, it will either be ceramic or RTV rubber potting. It may also use rigid tubes over the wires to create a hermetically sealed terminal end. While conductive heat transfer is ideal, radiant heat transfer will result in hot spots on the sheath or limit heat transfer.
The heating coil is the main component of a cartridge heater. This component is the actual resistance or electrical load. It is made of a metal alloy called nichrome. The coiled nichrome wire is wound around a ceramic core. There are different numbers of spirals per inch depending on the watt density. The alternating current source is either a 2 phase or three phase electrical supply. The coiled nichrome is heated by the current flowing through the coiled nichrome wire.
