ElectraTherm

What ElectraTherm does

ElectraTherm is a US-based cleantech company founded in 2005 and currently operating as a wholly-owned subsidiary of BITZER Group, headquartered at 4080 Enterprise Way in Flowery Branch, Georgia (with a separate Reno, Nevada address also listed in firmographic data). The company designs and sells Organic Rankine Cycle (ORC) power generation systems that convert low-temperature waste heat and geothermal heat (from 70°C to 150°C fluid sources) into clean electricity using proprietary twin-screw expander technology licensed from BITZER and operated with Pentafluoropropane (R245fa) as the working fluid. Its three core products are the Power Module 75 (up to 75 kWe, models 4400B and 4400B+), the Power+ Generator (up to 125 kWe, models 6500B and 6500B+, with cited efficiency up to 10%), and the Active Cooler line (AC800 at 800 kWth and AC1800 at 1800 kWth) which functions as a net-zero power cooling solution. Differentiated features include semi-hermetic dual-phase flow capability, operation below 5,000 rpm, a 10:1 turndown ratio, automatic unattended load-following, and a patented in-process lubrication system that lowers capex and maintenance costs to roughly 1-1.5 US cents per kWh generated.

ElectraTherm sells exclusively through a global distributor network rather than direct to end customers, providing free project assessments, performance and ROI estimates, an online Project Evaluation Form, and an Output Estimator tool to qualify leads. Target customer segments span engine and generator operators (diesel, natural gas, compression equipment), industrial manufacturers with kilns, furnaces, and boilers, methane handling facilities (landfills, biogas, wastewater treatment), oil and gas operations, low-temperature geothermal projects, biomass/biogas boiler installations, and biochar/pyrolysis operations pursuing carbon capture tax and credit incentives. Pricing is not publicly disclosed; ORC modules are positioned as components of complete installed systems whose total cost can vary up to three times depending on balance-of-plant and site factors, with the company making no recurring software or service revenue claims beyond project assessment and engineering support.

The company has raised approximately $35.3M across funding rounds from 2008 through 2016 (including $2.6M led by Interlaken Capital in 2008 and an $18.2M round in 2011) and now operates within BITZER Group's 46-company, 90+ country, 72-location industrial refrigeration footprint. Its most recent strategic action is a November 2025 integration of its ORC technology into Grain Ecosystems' equipment selection platform to serve biochar and pyrolysis project developers. Leadership includes founder and president Richard Langson, managing director Robert Emrich, and engineering manager Tom Brokaw; total headcount sits at 11-50 employees. No AI/ML capabilities, recurring software business, or public revenue disclosure is evident in the available data.

Direct peers

• Ormat Technologies: Ormat is the leading global manufacturer and operator of ORC-based geothermal power plants, using binary-cycle technology nearly identical to ElectraTherm's. It is the most established direct competitor in low-temperature heat-to-power applications.
• ENOGIA: ENOGIA specializes in small-scale ORC modules for waste heat recovery and low-grade heat, closely overlapping ElectraTherm's sub-200 kWe niche and serving industrial operators, biogas, and geothermal developers across Europe.
• Zuccato Energia: Zuccato Energia manufactures small-scale ORC systems for biomass, biogas, and industrial waste heat in the 50-300 kWe range — directly comparable product positioning, working-fluid choices, and target customers.
• Turboden (a Mitsubishi Power company): Turboden is a long-established ORC manufacturer for distributed renewable and waste-heat applications, serving biomass, geothermal, and industrial recovery with a broader kWe envelope than ElectraTherm.
• Exergy International: Exergy designs and supplies ORC turbines and full systems for geothermal and industrial waste-heat recovery, including low-temperature applications that overlap ElectraTherm's 70-150°C operating window.

Broad incumbents

• Atlas Copco: Atlas Copco's Power Technique division supplies industrial heat-recovery solutions, including ORC waste-heat-to-power units, alongside its compressor and generator portfolio. It competes with ElectraTherm across industrial engine heat recovery but as part of a much broader equipment portfolio.
• Siemens Energy: Siemens Energy's industrial portfolio includes heat-recovery steam generators, turbines, and ORC offerings for large-scale waste-heat and combined-cycle applications. It is a larger incumbent competing on the upper end of the addressable market.
• Elliott Group (Ebara): Elliott manufactures expanders and turbomachinery that compete with ElectraTherm's twin-screw expander at higher power ranges and in oil & gas, petrochemical, and process industries — a partial overlap on expander technology.
