Precision Power Control for Energy‑Efficient Industrial Heating Systems

We work with UK machinery OEMs to design and supply thyristor power controllers that improve the efficiency, stability, and controllability of electrical heating processes. Through custom engineering and OEM‑focused integration support, we help manufacturers reduce energy losses, lower operating costs, and deliver machines that remain competitive in demanding industrial environments.

in Modern OEM Heating Systems

Machinery OEMs supplying the UK industrial market face increasing technical and commercial pressure:

Rising energy costs impacting total cost of ownership (TCO)

Energy price volatility increases TCO sensitivity for end users.

Customer demand for lower kWh per unit of production

Customers demand measureable reductions in energy consumption per unit of production.

Greater scrutiny of energy efficiency and sustainability performance

More attention on efficiency performance and sustainability reporting.

Limited scope to redesign proven machine platforms

OEMs must improve performance without major changes to proven machine platforms.
In many electrically heated systems, energy inefficiency is driven not by the heater itself, but by poor power control, resulting in temperature instability, overshoot, and unnecessary electrical losses.

Why Matters

Thyristor power controllers provide high resolution control of electrical heating loads, allowing OEMs to regulate power delivery with far greater accuracy than contactor based or basic control methods.

Key engineering benefits include:

  • Precise phase‑angle or burst‑firing control of resistive and transformer‑coupled loads
  • Reduced temperature overshoot and tighter process stability
  • Lower RMS current and reduced peak loading
  • Improved overall system efficiency and heater life

Why it matters commercially

For OEMs, this translates directly into measurable reductions in energy consumption and operating costs, without changes to the mechanical design of the machine.

CD Automation Industrial Reliability

The CD Automation thyristor power controller range is engineered for long-term operation in demanding industrial environments where uptime, consistency, and durability are critical.

Robust mechanical and electrical design

suited to harsh industrial conditions.

High-performance, industrial-grade components

selected for thermal stability and long service life.

Innovative manufacturing techniques

that ensure repeatable quality, consistency, and reliability at scale.

Designed for Continuous Duty Operation

CD Automation thyristor power controllers are designed for continuous industrial duty, not intermittent or light-use applications.

Key design considerations include:

  • Thermal design optimised for sustained load conditions
  • Component derating to improve reliability and lifespan
  • Stable performance under fluctuating load and ambient conditions

Reliability & Lifetime Expectation

The CD Automation range is designed with a target MTBF of 10 years under normal industrial operating conditions.

This long-term reliability is achieved through:

  • Conservative electrical and thermal design margins
  • Selection of high-performance, long-life components
  • Controlled, repeatable manufacturing processes

For OEM engineers, this supports:

  • Long machine service life expectations
  • Reduced warranty risk
  • Greater confidence during engineering sign-off and design approval

Total Cost of Ownership (TCO): vs Low-Cost Control

The CD Automation thyristor power controller range is engineered for long-term operation in demanding industrial environments where uptime, consistency, and durability are critical.

Typical hidden costs

While low-cost power control solutions may appear attractive initially, they often introduce higher lifetime costs through:

  • Increased maintenance and replacement
  • Reduced heater life due to electrical and thermal stress
  • Energy losses caused by poor control resolution
  • Unplanned downtime and service intervention

How CD Automation reduces CTO

CD Automation controllers are engineered to minimise total cost of ownership by:

  • Extending component and heater lifespan
  • Maintaining efficiency over the machine lifetime
  • Reducing service requirements and operational risk

Illustrative Lifetime Savings Example (OEM Reference)

The following example is indicative and provided to support engineering and commercial evaluation.

  • Electrically heated machine load: 100 kW
  • Operating time: 6,000 hours per year
  • Energy cost: £0.15 / kWh

Annual energy cost: £90,000

A conservative 3–5% efficiency improvement achieved through improved thyristor power control equates to:

  • £2,700–£4,500 saved per year, per machine
  • £27,000–£45,000 over a 10-year machine life

These savings are achieved without mechanical redesign and can be validated during factory acceptance testing.

Lifetime savings

Why ?

The CD Automation thyristor power controller range is engineered for long-term operation in demanding industrial environments where uptime, consistency, and durability are critical.

This is power control designed to perform, and last.

  • Engineered specifically for industrial electrical heating
  • Proven in continuous-duty OEM applications
  • Built with performance margins for long service life
  • Designed to integrate cleanly into OEM machine platforms
  • Supported by technical expertise focused on OEM requirements

Addressing the Cost Question Upfront

It’s common for OEMs to ask why an industrial-grade thyristor controller costs more than basic alternatives.

The answer is simple: performance over time.

CD Automation controllers are not designed to meet minimum specifications, they are designed to deliver:

  • Stable, repeatable performance
  • Lower lifetime operating and maintenance costs
  • Reduced risk during commissioning and in the field

For OEMs and their customers, this translates into fewer problems, lower long-term costs, and greater confidence in every machine delivered.
