Custom cartridge heaters are among the most versatile and reliable industrial heating elements available today. They are specifically designed to deliver targeted, controlled heat to a wide variety of applications, from plastic injection molds to packaging machinery and laboratory equipment. While standard cartridge heaters serve many applications well, custom cartridge heaters go one step further — they are tailored to match exact size, power, temperature, and environmental requirements.

An immersion heater with temperature control is a highly efficient heating device designed to directly heat liquids within tanks, reservoirs, or process containers. Unlike simple heaters that operate at a fixed output, this type of heater integrates a temperature control system, enabling precise heating, improved energy efficiency, and enhanced safety.

A thermo sensor is a critical component in many temperature control systems, including HVAC thermostats, industrial machinery, medical devices, and household appliances. These sensors detect temperature changes and send signals to control units to regulate heating or cooling processes. Without a properly functioning thermo sensor, temperature management becomes unreliable, leading to inefficiency, equipment damage, and discomfort.

Before diving into their benefits, it’s important to understand what cartridge heaters are. Cartridge heaters are cylindrical heating elements that consist of a resistive wire coil encased inside a compact metal sheath, typically stainless steel or Incoloy. The coil is insulated with magnesium oxide (MgO), a material that provides excellent electrical insulation while enabling efficient heat transfer.

High density cartridge heaters are indispensable components in many industrial heating processes​, offering superior power density, precise temperature control, and long-term reliability. These features make them ideal for demanding applications where consistent heat and fast response times are critical.

Reheatek cartridge heater uses high quality Ni80Cr20 alloy as resistance wire, high purity (99.5%) MgO as insulation, and stainless steel as sheath.It provides concentrated heat in a limited space, small size but heat up quickly and precisely. A temperature sensor could be built-in to realize real-
