Ring heaters
Ring heaters are designed for heating elements with a cylindrical cross-section — especially where, due to limited space or unusual geometry, it is impossible to install standard band heaters.
Most often they are used to heat sleeves, extruder cylinders, nozzles or pipes in plastic processing equipment.
Their compact design, with a cover made of brass or stainless steel, protects the heating element from impacts and deformation during installation and operation of the machine. Thanks to this, ring heaters maintain a long service life even with frequent replacement or operation in harsh industrial conditions.
Precise inner diameter adjustment to a particular element provides full surface contact, which allows rapid heat transfer without loss and reduces energy consumption.
Uniform temperature distribution around the circuit minimizes the risk of overheating of one point and provides stable operating conditions for the heated component.

- In coil heaters it is possible to use a temperature sensor:
- Thermocouple type J (up to 650°C) *
- Thermocouple type K (up to 1000°C) *
- The specified temperature refers to the maximum operating temperature of the sensor and not the heater
It is possible to make heaters with uneven distribution of turns, in order to obtain the desired distribution of thermal power.
