ECOformator
The world is consuming ever more energy – a trend that's almost impossible to stop. And in most cases, nothing works without voltage conversion! Voltage conversion also means generating losses, which are released into the environment as heat and can have a harmful impact. But we at EMB now have THE SOLUTION: The EMB – ECOformator®! ECOformator® means maximum efficiency with minimal environmental impact. Our ECOformator® technology combines the highest quality materials with an optimized winding design, ensuring minimal power consumption! At EMB, we take environmental protection very seriously. We have been ISO 14001 certified since 1999! With our EMB – ECOformator®, we are now taking another giant step towards environmental protection, and at the same time, you save real money every day thanks to minimal power consumption! Our ECOformator® has approximately 35% fewer electrical losses, and after just TWO YEARS, our ECOformator® technology pays for itself for you or your customers and reduces the burden on our shared environment! Our ECOformator® in comparison: ► Maximum efficiency ► Minimal power consumption ► Low heat generation ► Longer lifespan ► Minimal environmental impact ► Approx. 40% less electrical losses* ► Return on investment after approx. 2 years** * Compared to conventional design ** At an operating load of 80%, 16 operating hours/day, electricity price 0.25ct/kWh, 250 operating days/year
