High performance: The Verdicorp range of expanders have frictionless operation,

and because of their unique motor and power electronics

technology, and infinitely vary their capacity to ensure con-

stant and accurate operation. The systems can deliver the

optimum amount of electrical power from the available heat.

Instead of turning machines on an off, the Verdicorp tracks the

available heat and its intelligent control ensures that the sys-

tems output is maximizes throughout its entire operating life.

With its “Smart Control” and its integrated VFD, it allows the

system to slow down as the available heat reduces and this

ensures the expander operates at its most optimal point dur-

ing the entire process, thus optimizing the overall systems

efficiency

Sustainable Energy Efficiency: Installing energy efficient equipment is very important to a energy recovery system, 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, and as oil contaminates the heat exchanger surface, but when there is no friction, then efficiencies can be maintained over the entire life of the system Verdicorp’s world proven oil-free magnetic bearing, soft-starting, synchronous PM motor, and integrated power electronics rede-fines reliability and the system continues to maintain its high effi-ciency year after year

Outstanding energy efficiency reduces operating budgets and

helps shrink facilities carbon footprint as truly green energy is

created from what normally goes to waste. Verdicorp’s technology: The Verdicorp blower is a single stage, variable speed expander, incorporating inbuilt VFD, digital magnetic bearings, soft starter and digital intelligent controls

Verdicorp’s turbo expander: The Verdicorp range of expanders are based on the well proven

Turbocor oil-free compressor technology. There are now over

30,000 machines operating throughout the world, so the products

are based on a well proven, highly efficient platform of technolo-

gies

Verdicorp produce a range of expanders ranging from a gross

output of 20kWe up to 115kWe and because of their oil-free na-

ture, they can be safely coupled together to operate to much

larger capacities

Oil-free Turbo Expanders: Improving ORC Performance

Developer of Sustainable, Environmentally Friendly Technologies

Magnetic bearings and bearing sensors:

Composed of both permanent and electromagnets with unique,

patented design for compact size and reliable high performance

Enables precisely controlled frictionless blower shaft rotation on a

levitated magnetic cushion

Bearing sensors, located at each magnetic bearing, feed back rotor

orbits and thrust/axial information in real time to bearing controller

Permanent-magnet synchronous motor:

Powered by PWM (pulse width modulated) voltage supply

High-speed variable frequency operation affords high efficiency,

compactness and soft start benefits

Touchdown Bearings:

Radially and axially located bearings support the rotor when the

blower shaft is not energized

Prevents contact between rotor and other metallic surfaces

Shaft and impeller:

Only one major moving expander component acts as rotor for per-

manent-magnet synchronous generator and the impeller is keyed

directly to shaft

Electronic package:

Rectifiers convert AC line power into a high voltage DC power

source

Delivering proven technology

Capacitors for smoothing DC power supply

DC-DC Converters for supply and isolation of high and low voltage

DC voltages

Network connections for external control and monitoring

PWM amplifier for power to electromagnetic bearings

Blower bearing and motor controller microprocessor

Variable Frequency Drive:

IGBT (Insulated Gate Bipolar Transistor) is an inverter that converts

DC voltage into an adjustable three-phase phase matched AC volt-

age

Signals from the generator/bearing controller determine the invert-

er output frequency, voltage and phase, thereby regulating the

current to match the grids electrical power. The speed of the tur-

bine is matched to optimize the generators performance as the

internal heat source varies throughout the day

Converts mechanical energy back into electrical energy. In the case

of Power failure, this patented control scheme allows for a normal

de-levitation and shutdown

Soft start module:

Significantly reduces high in-rush current at startup, providing ad-

vantages to line power systems and reducing thermal stress at the

stator

The startup in-rush current is less than 2 amps vs. —truly defining

soft starts

Turbo Expanders:

Verdicorp Turbo Expander: These expanders can be configured in either stand alone or multiple ex-

pander configurations. With the elimination of oil, the Verdicorp oil-free

expanders simplify ORC system designs, lower manufacturing costs, and

with their intelligent control, offer the optimum in system efficiency. The

Verdicorp ORC expander can operate with temperatures as low as 100

deg.C, making it ideal for solar and geothermal applications.

Awards: This technology platform has been recognized throughout the world as leading edge, and has led to some very significant awards being presented, these being the 2003 ASHRAE (AHR) Innovation Award for Energy, the 2004 EPA’s “Climate Protection Award”, the 2005 Natural Resource Canada Innovation Award for Energy, the 2007, Frost and Sullivan Award for Inno-vation, the 2008 Institute of Refrigeration – J&E Hall Gold Medal (London) for “Innovation, Application and Advancement of Refrigeration", and the 2009 James Harrison Medal, the most distinguished award presented by the Australian Institute of Refrigeration, Air-conditioning, and Heating (AIRAH).

Oil-free Turbo Expanders: Verdicorp now offers a range of high-efficient oil-free turbo expand-ers for use in Organic Rankine Cycle systems (ORC). These expanders offer exceptional performance, and with their intelligent control, variable speed and optimized diffusion, are designed to work at their most optimal efficiency point at all times. The easy to control, digital electronics are “the brain inside” which makes the Verdicorp expanders totally self optimizing while enabling sophisticated self-diagnostics, monitoring and control. This intelli-gence is easy to tap with various control outputs.

Easy to maintain: No oil service needs, no wear and tear on mechanical components, simple preventative maintenance.

The energy puzzle: Renewable power generation is the key piece of the puzzle that had to be solved in order for countries around the world to get off the energy addiction that the current modern society has become accus-tomed to. In order to meet the challenge, Verdicorp has developed a revolution-ary power generating expander that will help ORC manufacturers to offer the most advanced technology, while reducing both manufac-turing, operating and maintenance costs.

Sound Technology Base: The Verdicorp expander is based on the globally proven Danfoss Turbocor compressor technology, and no one knows this technology better, as it was the Verdicorp team that invented the technologies.
