Multistack ORCs & Turbo Expanders By Verdicorp
In 2020, Multistack acquired the Modular Organic Rankin Cycle (ORC) engine technology, and the Oil-Free Turbo Expander technology from Verdicorp. Verdicorp had developed these next generation, clean energy technologies for over 10 years, and had a wide range of ORCs, and a well established expander. Multistack believe that the addition of these technologies to the Multistack portfolio of chillers and heat pumps creates new opportunities, across a number of different applications.
The oil-free turbo expanders are used for converting low grade heat into useful electrical power. The expanders are used in Organic Rankine Cycle (ORC) systems, where heat that normally goes to waste, is captured and converted back into power. This system helps reduce energy costs by utilizing existing heat streams and converting the lower grade heat into useful work, which in turn improves the overall system efficiency.
Installing energy efficient equipment is very important to any plant, however retaining that efficiency in a sustainable way is even more important. Conventional oil lubricated systems drop off in efficiency over time as parts start to wear. By contrast, Verdicorp's oil-free system, with magnetic bearings have no mechanical friction and efficiencies can be maintained over the entire life of the system.
The Modular ORC’s can be configured to deliver useful power from a wide variety of heat sources including;
• Solar Thermal
• Geo Thermal
• Engine Heat Recovery
• Industrial Heat Recovery
When combined with Multistack’s world class oil-free centrifugal chillers, Multistack can deliver an Advanced Tri-Generation system, in which waste heat is turned into Power, and Chilled Water.
