EFIT SCR Power Controllers
The Perfect Fit for Simple Applications
Uncompromising process performance in a cost effective format
Easy to integrate and commission, yet highly cost effective, the EFit power controller provides no compromise control for resistive and infrared heating elements. Ideal for all heating applications and fully compliant to international quality, immunity, and emissions standards, Efit achieves outstanding stable, precise control in the most demanding industrial environments, even when cabinet space is at a premium.
The perfect fit for simple heating applications
Some Industrial processes such as heat treatment require precise temperatures in order to comply with regulations and it is imperative that the workpiece temperature is kept within specific limits. This can be difficult to achieve in industrial plants where the operation of large machinery can cause fluctuations in the voltage supply. In the case of resistive heaters a variation of 10% in the supply voltage will generate a 20% variation in the power to the load, resulting in undesirable temperature fluctuations. EFit contains built in compensation that continues to apply stable power with better than ±2% linearity at the boundaries of the load, even during fluctuations in the supply. The result is a reliable, repeatable heating process and high quality end products compliant to demanding heat treatment standards.

Improve Processes
environments, EFit will enable you to run continuously optimised
heating processes with minimum down time. This faster throughput improves OEE (Overall Equipment Effectiveness), helping you achieve
your KPIs (Key Performance Indicators).
Increase throughput
- Maximise utilisation of plant equipment
thanks to fast stable control response
Reduce down time

Control Precisely
Reduce hidden energy costs
- No wasted energy — built in compensation provides stable power control even during power fluctuations, eliminating unexpected changes in heater temperature
- Better power factor— save hidden energy costs with dedicated firing modes for each type of load, including a variety of burst modes that provide an efficient alternative to Phase Angle, such as advanced single cycle firing to reduce flicker in short-wave infrared heaters
Consistently high quality end products that comply to standards
- No scrap or rework - linearity better than ±2% of range, accurately controls heaters and maintains the correct load temperature
Standardize Globally
global environment where industry regulations form an essential part of the engineering supply chain.

Temperature Controllers:
Process Application Control
Whether it is Open-Loop or Closed-Loop Control, a good Control System is critical for long heater life.*
Here we demonstrate a Closed-Loop (Feedback) Control Set-up ~
Generally considered the optimal method, a closed-loop heater control system uses a power controller, temperature controller, and thermocouple to provide a constant output temperature, regardless of changes in airflow.
