Cartridge Heaters are also known as pencil Heaters are cylindrical shaped heating elements consisting of a resistance wire coil fused to solid conductors and metal sheath separated by insulation that provides excellent thermal conductivity and dielectric strength. Different insulation, sheath, and resistance wire materials provide greater temperature performance and offer a wide field of applications. Cartridge Heater is an excellent choice to use as a conductive source for heating solid metal plates, blocks, and dies or as a convective heat source for various liquids and gases.

Cartridge Heaters or pencil heaters can be used in a vacuum atmosphere with proper design guidelines. Cartridge Heaters are differentiated into three categories based on its watts density 1. low Density 2. Medium Density and 3. High Density. All three types of Cartridge Heaters have a separate type of internal construction and for any unique or different structure, it needs special purpose machines for production. We are one of the leading and large scale manufacturers in the Gujarat region equipped with the latest and finest manufacturing facility for all three types of Cartridge Heaters. We never compromise with our quality standards in terms of the manufacturing process and quality of raw materials. Moreover, our wide range of experience in the respective field made us expert and accurate. Our expertise, production capacity, testing facility, and our vision to deliver superior quality of products at a competitive rate in the market made us one of the best leaders. Our Heaters optimum performance under challenging circumstances appreciated by the end-users.
