Formable coil heaters
RP and RP T are high-density cold-forming heating elements with small cross sections. They are available straight or shaped, with or without thermocouple.
When heating corrosive products, those heating elements can be protected with a Teflon covering. Don't hesitate to contact us !
We have a large selection of standard models in various size in stock.
Formable coil heaters are liquid-proof and are available in two versions:
- RP, a cold-formable element.
- RPT, a cold-formable element but with built-in type J or K thermocouple, located about 5 mm from the end of the heater, as standard. The thermocouple is usually isolated from ground.
Standard dimensions are listed in our product data sheets. For specific requirements, please consult us.
Forming RP/RPT cold-formable heaters:
As a rule, formable coil can be bent manually with a spindle. For heating cylinders, we recommend the use of a winding device.
In all cases, avoid small radius and hammer blows.
Caution ! Never straighten a shaped coil !
We can also form your heaters to your requirements.
