What is DiOhmic™ Heating?
DiOhmic™ Heating is the proprietary name for our advanced coolant heating technology.
The term combines the concepts of:
- “Di” – referencing dielectric heating, which converts electric field energy into useful thermal energy.
- “Ohmic” – representing the controlled electrical-to-thermal pathway fundamental to the technology.
Together, these principles form DiOhmic™ Heating, a unique coolant heating system developed specifically for efficient thermal management applications.
Innovation Through Thermal Engineering
DiOhmic™ Heating technology has been developed to address the growing need for:
- Faster warm-up times
- Improved energy utilisation
- Reduced system complexity
- Electrification compatibility
- Enhanced thermal control
The result is a modern car coolant heater engineered for next-generation vehicle platforms.
