Product Description

Induction Heating Machine for Welding Preheat / PWHT / Joint Anti-corrosion Coating in Accurate Temp. Control

CR2000 series medium frequency induction heating system is designed and manufactured by Canroon, specially

for using of welding preheat, post weld heat treatment (DHT dehydrogenation heat treatment, ISR intermediate

stress relief), and joint anti-corrosion coating.
CR2000 is widely used and welcomed by oil&gas piping, and power plant construction & repair.
Application of shink fitting for motor stator is also very efficient.

Welding preheating and post-heating is an important application field of induction heating.
The welding of steel after preheating can reduce the stress,improve the welding strength,and
prevent cracking.Post-heating is used for dehydrogenation,annealing,tempering,normalizing
and other processes.

  • High Efficiency

This uniquely energy-efficient process converts up to 90% of the expended energy into useful heat, and

time-to-temperature is faster than conventional processes due to the method of applying heat, reducing

cycle time.

  • Friendly Interface and Accurate Control

The control board offers various parameters for setting so the heating process can be controlled precisely

by giving value to temperature, time, heating rate, cooling rate, etc.

  • Fault Record

Fault codes will display and be recorded for reference, and system will respond with protection action

like shutdown once fault occurs such as open-loop output or short out.

  • Various Control Mode

The interface offers two basic control mode to choose including temperature control and power control.

The former one has 4 modes of preheat, bake-out, PWHT, custom. The last one has 2 modes of constant

power and power VS time. Each mode offers different parameters to set. Thus brings the benefit of wide

applicability and precise control.

  • Easy Maintenenace

Due to modular design, the maintance will be easy and low-cost.

  • Self Diagnosis

Once fault occurs, CR2000 will act with display of fault code, which was detailed explained in the manual book.

  • Uniform Heating

The heat is induced within the part itself by alternating electrical current, thus uniform temperature throughout

the heating zone is realized.

  • Replaceable Heating Inductor

Apart from induction blanket (blanket type inductor), there are multiple heating inductors for choice including

induction coil/cable, C-type inductor, plate type inductor, Split-core inductor, O type inductor, all of which are

easily dismountable and reconnected to the power source. So the power source can be used for heating

workpiece of different size and shape.

  • Abdudant Accessories

We offer multiple accessaries like thermocouple, thermocouple welding machine, digital temperature-recorder,

remote switchgear, output extension cable, insulation blanket, etc. Complete solution saves your time and ensures

you to start work soon after received our delivery.
