Flowery Branch, Georgia – ElectraTherm, a leader in distributed, waste heat to power generation, has launched a new POWER+ GENERATOR product line with an integrated BITZER twin screw expander. The next-generation model, the POWER+ 4400B, uses BITZER’s proven, exclusive compressor and expander technology, patented and patent pending lubrication and bearing schemes to engineer the only small-scale ORC technology of its kind.
One major advantage of the BITZER integration is a semi-hermetic design which couples the expander and generator as one assembly. This results in no shaft seal between the expander and generator, greatly enhancing reliability. In addition, the BITZER expander, exclusive to ElectraTherm, is designed for dual phase flow; both vapor and partial vapor mixtures are easily handled by the robust twin screws. The robust BITZER expander casing also allows the 4400B to increase input temperatures and internal pressures to broaden waste heat to power applications. These improvements will enable ElectraTherm to grow its leading position in the waste heat to power industry.
ElectraTherm’s distributed power generation units use low-temperature waste heat which had zero value until now, on applications such as stationary engines, biomass, geothermal, flare elimination, wastewater treatment plants, and more. The POWER+ 4400B is easily transported, installed and operated with a small footprint, and comes fully-packaged with an output up to 75kW — a 15% increase over the original 4400.
Additional benefits of the POWER+ include:
- Low maintenance, with no gear boxes or oil changes
- Fully automated controls with remote access capabilities
- Robust BITZER twin screw expander
- Modular design for ease of installation
- CE certification
Today POWER+ GENERATORS operate around the globe with more than 100 units shipped, and a fleet run time exceeding 1.1 million hours in various applications. For more information please visit the website at www.electratherm.com.
