- RADIAL OUTFLOW TURBINE
Exergy’s Radial Outflow Turbine
Conceptualized by Exergy the Radial Outflow Turbine (ROT) was launched in 2009, innovating the global ORC industry. It is a confirmation of Exergy’s status as a market game changer.

MORE EFFICIENCY AND FLEXIBILITY WITH THE ROT

What is the key feature of the ROT?
The ROT configuration makes it possible to convert the energy contained in the organic fluid into mechanical power with higher efficiency than competing technologies on the market such as the traditional axial or radial inflow turbine.
Our Radial Outflow Turbine technology is covered by multiple IP rights and Exergy’s R&D team is always working to develop it further with new patents.
ROT strengths:
1
NATURAL ACCOMODATION OF WORKING FLUID EXPANSION

As it expands, the fluid encounters greater surface area, causing taller blades in the first and shorter blades in the last stages, thus facilitating a broader range of applicable fluid conditions
2
LOW SPEED TURBINE

No gearbox

High reliability

Low noise

Longer life of the bearings
3
STRAIGHT BLADES AND RADIAL DESIGN

Minimal 3D effects and turbulence
4
EASE OF MECHANICAL GROUP EXTRACTION

No fluid loss or drainage

Easy and rapid maintenance

Less tip leakage and disk friction losses

No “overhaul” maintenance on the turbine
5
SIMPLE DESIGN

Compact solution

Simple and easy construction
6
STANDARD MECHANICAL DESIGN FOR EACH TURBINE FRAME

The fluid-dynamic design of each turbine is optimized in order to reduce supply time, guaranteeing maximum efficiency without the need for mechanical redesign
7
MULTIPLE PRESSURE ADMISSIONS POSSIBLE ON A SINGLE DISK

Cost effective solution

Less limitations on cycle pressure

20% more power than a single level system with a simple configuration

Suitable for temperature heat sources as low as 90°C
8
UP TO 9 STAGES ON A SINGLE-DISK TURBINE

Better exploitation of high enthalpy resources

Extreme flexibility for changing heat source conditions, in terms of flow, temperatures and constituents

Up to 6% additional efficiency over the axial turbine
