Cartridge Heater Stock


We're passionate about bringing quality ex-stock cartridge heaters to our customers 


Our Philosophy

Is to supply high quality and ex-stock cartridge heaters, all this at a fair price and a delivery service to match.

We know how important component parts are when you have an emergency breakdown.

We pride ourselves on the service we give to all of our customers.


Our Passion

Is to surpass our customer expectation in all areas, this will ensure they come back again and again. Our passion is also to provide a ex-stock service for all sizes of cartridge heaters that's why we have such a large stock holding. This means your production down-time will be cut down to a minimal and less stressful.


Our Vision

Continuously improving the quality and performance of our cartridge heaters that will meet and surpass their current requirements.

To provide a un-surpass-able service which can be measure against our customer feedback.

Heater Diameters

Cartridge heaters are available in metric and imperial sizes 6.5mm(1/4") to 40mm(1.5") diameters and up to 2m in length.

They are supplied with high watt densities as standard for the most  demanding of applications, medium and low are also offered on request.


Below are the standard stock diameters with the actual sizes. This allows for the heater to expand slightly under temperature for a tight fit and contract when cold to enable the heater to be taken out.

Please note that the heaters must not be pulled out by the leads but pushed out from the oposite side.

Thermocouple and PT100(RTD) sensors

What is a thermocouple sensor?


A Thermocouple is a sensor used to measure temperature. Thermocouples are made from two wire made from different metals. These wires are welded together at one end to form a tip called a junction. The junction is where the temperature is measured. When the junction sees a change in temperature, a mili-voltage is created. This signal is then calulated by a temperatue controller to give a accurate temperature reading. 

The most common are type K and J of which we keep stocks in 6mm diameter and various lengths.


What is a RTD (PT100) sensor?

Resistance thermometers, also called resistance temperature detectors ('RTD's), are used when measuring temperatures by checking the resistance of the RTD element with temperature. Most RTD sensors made up of a length of fine coiled wire wrapped around a ceramic or glass core which is placed inside a sheathed probe to protect it. The RTD element is made from a pure material, typically platinum, nickel or copper. The material has a predictable change in resistance as the temperature changes; it is this predictable change that is used to determine temperature.


They are use in applications for the higher accuracy and repeatability compared to thermocouples.
