Who We Are

ElectraTherm by BITZER Group provides industry-leading heat recovery solutions utilizing the Organic Rankine Cycle (ORC) along with proprietary technologies to convert sources of low temperature heat into clean, usable power. Our simple and effective solutions use hot water as fuel – so no additional fuel consumption or emissions – to increase efficiency, reduce energy costs, and decrease overall emissions. Our commercially proven ORC systems utilize heat sources as low as 70°C to generate up to 125 kWe (with a 250 kWe system in development) of clean electricity.

Supported by BITZER, the world’s largest independent manufacturer of refrigeration compressors, the ElectraTherm team is able to continuously develop industry-leading ORC heat recovery technology such as our heat to power system, the Power+ Generator, and our net-zero cooling to power system, the Active Cooler. This partnership provides ElectraTherm the vast resources needed to provide world-class services and support wherever and whenever needed. Having shipped over 100 ORC systems to over 13 countries (with dozens more scheduled) achieving over 2,000,000 hours of operation, we are a global leader in low temperature waste heat recovery.

Common applications include engine waste heat, boiler process heat, combined heat and power, net-zero cooling, amongst others. See our Applications Page for more information.

WHY

More than half of all applied energy is lost as heat, commonly known as waste heat. During a time when the global demand for energy is exploding, this is an immense waste of resources and a major contributor to global warming.

We strive to show the world that taking advantage of this wasted and abundant resource is not only profitable, but practical. Waste heat recovery is good for business, the environment, and actively supports ESG strategy.

WHAT

We turn heat into power. It is that simple. As long as the heat is in liquid form, i.e. hot water, we can generate clean electricity with no additional emissions or fuel consumption.

Have a higher temperature heat source such as exhaust gases? With an additional heat exchanger  we can convert that into clean, usable electricity as well.

HOW

We utilize the Organic Rankine Cycle (ORC) to convert sources of low temperature heat – such as geothermal and waste heat – into usable, profitable power. While traditional Rankine Cycles (RC) convert sources of high temperature heat into power, our technology focuses on low temperature heat. This allows businesses of all sizes to take advantage of this innovative technology.

2005

Established in 2005 in Reno, Nevada, our mission has never changed. To provide the world with efficiency solutions that provide clean energy while reducing emissions. We aim to show the world that waste heat recovery is not only profitable, but practical.

As the world looks to the future, there is more pressure than ever to reduce our carbon footprint while finding more efficient and sustainable methods to use and generate energy. One of the simplest ways to achieve this is by using ORC technology to take advantage of a resource you already have – heat.

2011

After years of hard work, complicated engineering, and a series of successful demonstrations backed by private and government organizations such as the Department of Energy and Department of Defense, ElectraTherm begins to ship commercial units.

President Obama even made an appearance,
“When you’re talking about waste heat, every business, every industry, is generating some sort of energy byproduct, some sort of heat. It’s going up in smoke stacks and nobody is using it. And the question is , can we capture that energy and use it in a smart way? That’s what ElectraTherm is all about.”

2015

The ‘Green Machine’ is rebranded into the ‘Power+ Generator’. The new name was adopted to better describe the capabilities of the product, it does much mare than generate power. It increases efficiency, reduces energy consumption and costs, reduces your carbon footprint, fulfills the cooling needs of engine radiators, and even serves as a CHP (combined heat and power) unit.

2016

In 2016, ElectraTherm was acquired by BITZER, the world’s largest independent manufacturer of industrial and commercial refrigeration equipment. BITZER is represented across the globe with over 3,000 employees generating sales over $1 billion USD.

With this acquisition, ElectraTherm combined headquarters with BITZER in Flowery Branch, Georgia. Along with better access to resources, the facility had recently been upgraded with a 50,000 square foot test cell allowing the ElectraTherm team to continue developing industry-leading ORC systems.

2018

With installations around the globe, ElectraTherm’s fleet exceeds one million operating hours.

2019

The integration of BITZER’s twin screw expander, modified exclusively for ElectraTherm using proprietary technologies, marks the next generation of ORC technology. A major advantage of this upgrade is the new semi-hermetic design that greatly enhances dependability. The expander allows for dual-phase flow, accepting disruptions in both temperature and flow while allowing for moisture. Along with the improved cost and quality comes a 15% boost in performance.

2020

Arising from the need for a net-zero cooling system cam the Active Cooler. This self-powered cooling unit uses the same ORC technology as the Power+ Generator to cool the engine (or other heat source) during peak demand and generate additional electricity during times of low cooling demand. Since the ORC process naturally reduces the cooling load 70-100%, the system is able to prioritize the production of electricity for a majority of the time. It is the only power-producing cooler of it’s kind in the world.

2021

New additions to the test cell are completed, allowing for further development of the  Active Cooler and larger 250 kW unit.

With over 100 ORC applications in over 13 countries, ElectraTherm’s fleet exceeds two million operating hours.
