PTC Cartridge Heater for Medical Equipment

Product Description

PTC Cartridge Heater for Medical Equipment

Our cartridge heater is crafted from a sturdy cylindrical stainless steel tube, offering outstanding resistance to corrosion. Within, a precisely wound heating wire gracefully coils around a high-quality ceramic core, creating the powerhouse of this remarkable heater.

The coil count is meticulously customized to the heater's power requirements, ensuring superior heat distribution and extending its operational life. This intelligent design also reduces oxidation of the heating wire, even at high temperatures. Be it heating solids, liquids, or gases, our cartridge heaters shine in efficiently transferring heat through conduction when in direct contact with the heat sink. Perfect for molding plastic and rubber components in the automotive industry, these heaters are equally indispensable in sectors like food processing, chemical, electronics, medical equipment, packaging, and nuclear industries.

 

Beyond our comprehensive standard offerings, we excel in custom-designing and producing cartridge heaters uniquely tailored to meet your specific needs.

Cartridge heaters boast a crimped-on or swaged-in construction, featuring a high-grade nickel-chromium resistance wire for unmatched performance.
This wire is intricately wound around a top-quality MgO core, which is perfectly centered within a durable stainless steel casing.

Factors - How to Choose the Right Cartridge Heaters:
Consider these key factors to make the optimal selection for your heating needs:
1. Operating temperature - ensure compatibility with your specific application.
2. Watt density of the heating element - determine suitable power requirements.
3. Sheath material - choose between corrosive or non-corrosive environments.

• • Assess the temperature of the corrodent to ensure longevity.
• • Evaluate the degree of aeration exposure of the corrodent for optimal selection.
• • Consider the velocity of the corrodent for precise application.
