For heavy cartridge heaters, there is a gate or insertion point on the device to be heated. An inch rule for adjustment is to make the hole diameter no more than 0.005 inches larger than the heating diameter. We offer a full range of cartridge heaters with high density watt density to meet your specific needs. The “Max K” cartridge heater is designed to meet increasingly demanding requirements. Our high density compaction process ensures maximum reliability under unfavorable operating conditions.
The basic structure of a cartridge heater includes a ceramic core, resistance wire, insult, a pod and lead wire. Manufacturers organize these common factors differently to improve the quality and heating capabilities of their products. Motor block heaters are a reliable method to support car performance at cold temperatures.
For applications that require a specific insertion depth or that must be held in place, Nexthermal offers standard flanges for most diameters. Elmatic Manufacture Pattern heaters designed to meet the full spectrum of pattern heating applications. Although a standard range of cartridge heaters is available, we specialize in designing and producing cartridge heaters based on the requirements of our customers. It is important to choose the right building heating for your application. The sheath is the part of the cartridge heater that contacts the material or substance to be heated.
The thyristor power controls are valuable in extending the life of high watt density heating elements because they effectively eliminate outside cycling. There are different temperature controllers and sensors that can be used depending on the application. One of the most popular types of sensors for cardboard heater applications is temperature sensors for surface mounting.
The many sizes, types, configurations and modifications of cartridge heaters make them an ideal method to provide targeted heat. Cartridge heaters fit into any application that requires a powerful heat source. They fit perfectly into an application and transfer heat Mica Bands to the required focal point. The split pod cartridge heater is coreless, but contains a continuously operating cable immersed in an insulating material. This type of cartridge heater is a recent development designed to fix specific pattern heating failures.
3 “leading past the armor is standard. If necessary, specify longer leads. Specify the galvanized or stainless steel armor and the total length of the cartridge heater. Teflon leads and seals: Teflon® insulated lead cables with the final Teflon® seal on the cartridge heating envelope provide superior moisture and chemical resistance. This design requires at least a cold 1 “section at the outlet end of the heater. 12 “wires are standard.
Enter the G-235 curve with an operating temperature value of 200 ° F higher than the actual operating temperature to determine the maximum allowable density of watts at 480 volts. Vacuum control: When heating elements are used on a vacuum block, the inside of the holes must be pre-oxidized to improve emissions. Vacuum action generally requires significant reductions in the maximum allowable watt density. Where possible, the installation must be designed so that the end of the heater is out of the void. When the end of the heating cable is in the vacuum, a voltage of 120 volts or less is recommended.
Made with a high density of watts, they warm up in minutes, resulting in cost savings in shorter man hours that remove nuts from bolts and cleats. This heating design is made from pods with a specific diameter that fit the standard hollow bolts of the industry. High water densities with special heated lengths distribute the heat evenly over the surrounding bolt. The surface load is defined in the machine industry standard as the power per unit area on the heating surface, in watts per square centimeter (W / cm²). The maximum surface load that any type of pod material can support is different. When consulting cartridge heaters with REheatek, it is necessary to communicate with the sale of REheatek or engineers to obtain the best solution.
Designed for easy installation, cartridge heaters become smaller than their nominal diameter. However, they can be found in various compact sizes in options with low or high watt density. Choose a low watt density cartridge heater for packaging, heat sealing, laminating, cooling and melting tanks or nozzles. High density cartridge heaters are used in plastic extruders, hot printing, medical equipment, food processing, hot channel molds and other plastic molding equipment. The use of square cartridge stoves attached to milled grooves on the tool surface has become particularly cost effective with the advent of modern CNC machining. Square heaters attached to cooled, closed grooves ensure optimal heat transfer to the application, while the heater can be easily removed for cleaning or maintaining the system.
