Manufacturing & Product Range
Our production facilities specialize in the design and manufacturing of cartridge heaters in standard and custom configurations, covering a wide range of diameters, lengths, watt densities, and industrial applications.
Standard Cartridge Heaters
General-purpose cartridge heaters designed for reliable heating in molds, dies, plates, and metal components. Suitable for a wide range of industrial applications with balanced performance and durability.
High Watt Density Cartridge Heaters
Designed for applications requiring intense heat output in limited spaces. These heaters deliver fast thermal response and high surface temperatures for demanding processes.
Low Watt Density Cartridge Heaters
Optimized for gentle and uniform heating where lower surface temperatures are required. Ideal for sensitive materials and applications requiring extended heater life.
Precision Cartridge Heaters
Engineered for applications requiring tight temperature control and uniform heat distribution. Commonly used in tooling, medical equipment, and precision manufacturing.
Cartridge Heaters with Thermocouple
Integrated thermocouple options (J or K type) allow accurate temperature monitoring and closed-loop control directly at the heat source.
Custom Cartridge Heaters
Tailor-made solutions developed according to customer drawings and technical requirements. Dimensions, wattage, voltage, leads, and materials can be fully customized.
Miniature / Micro Cartridge Heaters
Compact cartridge heaters designed for small diameters and tight installation spaces. Ideal for electronics, laboratory equipment, and precision components.
Cartridge Heaters Lead Wire Options
Available with fiberglass, silicone, or PTFE insulated lead wires to suit different temperature ranges and environmental conditions.
Cartridge Heaters with Flange or Stop Collar
Designed for precise positioning and secure installation. Flanges and collars ensure consistent insertion depth and improved heat transfer.
High-Temperature Cartridge Heaters
Manufactured for extreme operating conditions using advanced alloys and insulation materials. Suitable for continuous high-temperature industrial processes.
Type 0 Cartridge Heaters
Basic cartridge heaters without internal thermocouple, designed for standard heating applications where external temperature control is used. They offer a simple, cost-effective solution for molds, plates, and general industrial heating.
Superior Performance in Cartridge Heater Technology
Caldor cartridge heaters are manufactured using advanced MgO compaction technology, ensuring high thermal efficiency, long service life, and stable performance under demanding industrial conditions. This manufacturing approach allows precise positioning of the resistive wire around a high-purity magnesium oxide core, significantly improving heat transfer to the outer sheath.
In high-density configurations, the resistive wire is placed extremely close to the heater’s external tube. This design enables rapid and uniform heat distribution while maintaining a lower internal wire temperature compared to conventional cartridge heaters. As a result, thermal stress on the heating wire is reduced, preventing overheating and extending operational durability.
Caldor cartridge heaters are widely used in tool heating, die slots, special-purpose machinery, polymer processing equipment such as screen changers and filter systems, as well as packaging machinery and air heating applications. Their robust construction and consistent performance make them suitable for both continuous and intermittent industrial processes.
Type 0 cartridge heaters, manufactured without an external jacket, are specifically designed for air heating applications and installation in dip pipes where direct heat exposure is required.
Screw-in cartridge heaters (Type EP) are engineered for direct heating of solid, liquid, and gaseous media. Designed for horizontal installation, they are commonly used in water tanks, oil heating systems, surface treatment processes, air heating, and tooling applications.
Through precision engineering, controlled manufacturing processes, and high-quality materials, Caldor delivers cartridge heater solutions that combine efficiency, reliability, and application-specific flexibility..
