Cleanfield Energy Receives UL Certification for Its 3.5KW Vertical Axis Wind Turbine Inverter

ANCASTER, ONTARIO, Jul 07 (MARKET WIRE) --
Cleanfield Energy(R) ("Cleanfield") (TSX VENTURE: AIR), an international
leader in Vertical Axis Wind Turbines (VAWT), announced today that its
proprietary Inverter for the V3.5 VAWT has been tested and certified to
UL standard 1741.

Cleanfield's Inverter was tested and determined to be in compliance with
UL 1741-Standard for Inverters, Converters, Controllers and
Interconnection System Equipment for Use with Distributed Energy
Resources. The testing was done by CSA International who is accredited by
the Occupational Health and Safety Administration (OSHA) US Department of
Labor as a Nationally Recognized Testing Laboratory (NRTL).

While most small wind turbine manufacturers in the marketplace today use
generic commercially available inverters, Cleanfield has specifically
engineered the Inverter to optimize the performance of Cleanfield's VAWT.
This allows the incorporation of proprietary safety and performance
enhancing features such as vibration monitoring with frequency band
skipping, full anemometer closed loop feedback allowing for power curve
optimization and over speed protection resulting in a safe and fully
integrated VAWT system. The topology and basic algorithms used in the
inverter can be applied for use in larger power Inverters with only
hardware upgrades. This topology will enable us to control systems that
use induction generators as well as synchronous generators.

"This is a very significant event for Cleanfield, said Tony Verrelli, CEO
of Cleanfield Energy. The UL certification of our proprietary inverter
technology and solution, proves that we have designed it to the high
level of the Underwriters Laboratory's safety standards."
