SprayCool(R) Technology Cited as Key to Installing Sensor Electronics in

                           MQ-1 Predator Aircraft



    LIBERTY LAKE, Wash., July 28 /EMWNews/ -- SprayCool, a recognized

leader in the development of advanced thermal management and environmental

isolation products for military, aerospace and industrial applications,

announced today the award of a contract from Northrop Grumman Corporation's

(NYSE: NOC) ISR Systems Division under which the company will provide its

liquid-cooled enclosures for the U.S. Air Force Airborne Signals

Intelligence Payload 1C (ASIP-1C) program. The SprayCool enclosures will

house signals intelligence electronics for the Air Force's SIGINT-equipped

MQ-1B Predator Unmanned Aircraft System (UAS), in support of Predator's

tactical warfighting role, sometimes described as a hunter/killer/scout

mission.



    Under this contract, the SprayCool Multi-Platform Enclosure (MPE) was

selected by Northrop Grumman as a critical component in the ASIP-1C sensor

payload for SIGINT-equipped Predator aircraft. Additionally, SprayCool

selection allowed Northrop Grumman and the Air Force to leverage their

previous investment, by enabling them to use the same electronics as on the

baseline ASIP program on other platforms. (See release by Northrop Grumman

issued on 22 April 2008).



    Product



    The MPE provides complete environmental isolation for the system, and

is also unique in its ability to manage operating temperatures for the

computing electronics in extreme environmental conditions.



    Similar to the variant SprayCool ASIP enclosure flying aboard the U-2

and Global Hawk platforms, SprayCool's MPE chassis enables optimum

electronics performance and increased reliability for the SIGINT

application. The scalable SprayCool enclosure, which is being adopted in a

variety of military manned and unmanned airborne applications, will be

deployed on Predator using a 9- slot configuration.



    "This award is a direct result of the performance of our SprayCool

enclosures onboard the U-2 and Global Hawk aircraft. The selection of

SprayCool for the Predator UAS further validates the effectiveness of our

solutions, and positions us for similar applications for upcoming DOD

airborne ISR programs where existing and new electronics components can be

packaged together and deployed more quickly," said Matt Gerber, SprayCool's

President and Chief Executive Officer.



    SprayCool Technology



    SprayCool's patented two-phase liquid cooling technology (see video)

uses a fine mist of non-corrosive, non-conductive liquid, sprayed in a thin

layer, which evaporates and cools electronics. The process continuously

cycles within a sealed, closed loop system. In doing so, SprayCool products

isolate the electronics from dirty, corrosive environments found in

military and industrial applications resulting in cooler, higher

performance, and more durable electronic devices. The technology provides

an efficiently controlled and isolated environment for a broad mix of

electronics in a package that is significantly smaller, lighter, and more

power and cost efficient, and faster to deploy by the integrator.



    The SprayCool MPE enclosures will be delivered to Northrop Grumman in

2008.
