ElectraTherm by Bitzer Group

ElectraTherm is a global leader in small-scale waste heat recovery. ElectraTherm's fuel-free, emission-free heat recovery process utilizes the Organic Rankine Cycle (ORC) and proprietary technologies to convert excess heat (as low as 70°C) into clean electricity (up to 150 kW). ElectraTherm's next generation ORC solutions, the Power+ Generator and Active Cooler, are proven to reduce or eliminate energy costs, engine de-rate, and the cooling parasitic load - substantially increasing efficiency and revenue. ElectraTherm's waste heat to power and net-zero power cooling solutions allow companies to benefit from a more circular economy and achieve their sustainability goals.

BITZER, the world’s largest independent manufacturer of refrigeration compressors, acquired ElectraTherm in 2016. With their distributors and manufacturing sites for reciprocating, screw & scroll compressors as well as pressure vessels and now screw expanders, BITZER is represented all over the globe. In 2017, approximately 3,400 employees earned sales approaching $1 Billion. ElectraTherm and BITZER US share their headquarters located in Flowery Branch, GA.

'Developing energy-efficient solutions is one of our main goals - and the waste heat to power market offers tremendous potential. ElectraTherm's ORC technology enables us to make better use of an abundant, and untapped resource of waste heat. This builds on BITZER's commitment of responsible climate protection. There are clear synergies in our markets and technologies, and we are eager to combines our efforts to further grow our respective markets.'

WE BELIEVE IN MODERN SOLUTIONS TO A GLOBAL PROBLEM

More than half of all applied energy is lost as heat, this excess heat is commonly referred to as waste heat. This heat is an immense and sustainable resource that goes highly underutilized today. Waste heat comes in many forms – from boiler and industrial process heat to engine waste heat and even low-temperature geothermal heat.

In the past, only large-scale applications with consistent high temperature heat made viable candidates for waste heat recovery. Today, with ElectraTherm’s modern systems, applications with lower temperature heat sources can now also reap the benefits of converting their excess heat into clean electricity. Waste heat recovery is good for business, the environment, and actively supports corporate ESG strategies.

WHY WE DO IT

With global energy demand exploding and nations seeking out sustainable forms of power, this lost energy represents a vast waste of resources and a major contributor to global warming.

Waste heat recovery is an easily accessible, cost-effective, and simple method of curbing global energy demand and emissions without relying on extensive infrastructure. We strive to show the world that taking advantage of this wasted and abundant resource is not only practical, but profitable.

WHAT WE DO

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 or thermal oils? With an additional heat exchanger we can convert that into clean, usable electricity as well.

HOW WE DO IT

We utilize a closed-loop Organic Rankine Cycle (ORC) along with proprietary technologies to exploit the temperature difference between a heat source and condensing source. This process consumes heat as fuel, generating clean electricity while reducing energy usage, the cooling load and associated emissions.

ElectraTherm's ORC systems boast industry-leading efficiencies and the lowest heat requirements in their class, allowing businesses of all sizes to take advantage of this innovative technology. Read more about our process in the Knowledge Center.
