Delphi’s Heat and Mass Exchanger Helps Coolerado Earn Top-10 Green Building Award

January 23, 2007 - TROY, Mich. — The Coolerado Cooler, a revolutionary air conditioning system which features Delphi Corporation’s (PINKSHEETS: DPHIQ) Heat and Mass Exchanger (HMX), has been named a “Top-10” green building product for 2006 by the editors of GreenSpec and Environmental Building News.

The publications’ editors made the announcement at the 2006 GreenBuild International Conference & Expo in Denver last month. Honorees were recognized for introducing exceptionally innovative products to the market.

Delphi’s HMX is the “engine” behind the Coolerado Cooler, which is a new residential series of water-fueled, high-efficiency air conditioners. Air conditioning systems using the Delphi HMX can cool homes, office buildings and industrial spaces across the globe for significantly less operating cost than traditional cooling systems without generating greenhouse gas emissions.

Delphi signed an agreement last year with Cooler Air Systems LLC (CAS) of Arvada, Colo., to be the world’s exclusive manufacturer of heat and mass exchangers. The Coolerado series of residential products, marketed by CAS affiliate Coolerado Corporation, is the first product line developed around this groundbreaking technology.

“Whether it is health and safety, the natural environment, or the economy, the built environment significantly impacts our lives,” said Joseph Dunlop, commercial manager, Delphi Thermal Energy Systems. “Delphi is honored to be recognized for its commitment to develop and promote energy-efficient technologies that support building green and reduce the negative impact of technology on the environment.”

As an indirect evaporative cooling system, the Coolerado Cooler relies on the evaporation of water to cool a space without raising humidity. It can deliver as much as six tons of cooling with an electrical consumption of 1,200 watts, which is a tremendous improvement over traditional air conditioners.

HMX — How it works

Delphi’s HMX system capitalizes on a thermodynamic cycle known as the Maisotsenko Cycle or M-Cycle. The M-Cycle harnesses the endless supply of atmospheric energy to drive sensible cooling with maximum efficiency. In the case of the HMX, cool air is produced via the water-fueled M-Cycle without adding a drop of moisture.

The hotter it gets outside, the better the Delphi HMX works. The cooling capacity and Energy Efficiency Ratio (EER) of an HMX application increase along with the temperature outside, a feature which dramatically reduces power consumption during peak demand when power costs the most.

The HMX is modular, which allows HMX applications to be sized to any cooling capacity requirement. Because it is an evaporative technology, the Delphi HMX is most effective when used in stand-alone cooling solutions in hot, dry climates — but it can also be used for turbine inlet cooling and in concert with direct expansion systems, energy recovery systems, dehumidification systems and more to yield applications of all shapes and sizes suited to any environment.

Delphi’s commitment to protecting the environment

“We are excited to be recognized for making the most of the energy we consume, and to see interest in Delphi’s ’green’ thermal technologies grow. But above all, the Top-10 award helps demonstrate Delphi’s commitment to the environment and its sensitivities to the needs of the present and the demands of the future,” said Raymond Johnson, product business unit director, Delphi Thermal New Markets. “By focusing on alternative energy sources, more efficient climate control and comfort systems, and cutting edge technologies consistent with this commitment, Delphi is taking an important series of steps in the right direction as a global citizen.”

Delphi’s HMX featured at the AHR Tradeshow and Expo — Jan. 29-31 in Dallas

Delphi will be featuring the Delphi HMX along with air movement technologies at the AHR Tradeshow and Expo in Dallas, Jan. 29-31 at the Dallas Convention Center (booth #5147, hall “F”).

FORWARD LOOKING STATEMENT This press release, as well as other statements made by Delphi, may contain forward-looking statements that reflect, when made, the company’s current views with respect to current events and financial performance. Such forward-looking statements are and will be, as the case may be, subject to many risks, uncertainties and factors relating to the company’s operations and business environment which may cause the actual results of the company to be materially different from any future results, express or implied, by such forward-looking statements. Factors that could cause actual results to differ materially from these forward-looking statements include, but are not limited to, the following: the ability of the company to continue as a going concern; the ability of the company to operate pursuant to the terms of the debtor-in-possession facility; the company’s ability to obtain court approval with respect to motions in the Chapter 11 cases prosecuted by it from time to time; the ability of the company to develop, prosecute, confirm and consummate one or more plans of reorganization with respect to the Chapter 11 cases; the company’s ability to satisfy the terms and conditions of the Equity Purchase and Commitment Agreement with its Plan Investors; the company’s ability to satisfy the terms and conditions of the Plan Framework Support Agreement with GM and its Plan Investors (including the company’s ability to achieve consensual agreements with GM and its U.S. labor unions on a timely basis that are acceptable to the Plan Investors in their sole discretion); risks associated with third parties seeking and obtaining court approval to terminate or shorten the exclusivity period for the company to propose and confirm one or more plans of reorganization, for the appointment of a Chapter 11 trustee or to convert the cases to chapter 7 cases; the ability of the company to obtain and maintain normal terms with vendors and service providers; the company’s ability to maintain contracts that are critical to its operations; the potential adverse impact of the Chapter 11 cases on the company’s liquidity or results of operations; the ability of the company to fund and execute its business plan (including the transformation plan described in Item 1. Business “Potential Divestitures, Consolidations and Wind-Downs” of the Annual Report on Form 10-K for the year ended December 31, 2005 filed with the SEC) and to do so in a timely manner; the ability of the company to attract, motivate and/or retain key executives and associates; the ability of the company to avoid or continue to operate during a strike, or partial work stoppage or slow down by any of its unionized employees; and the ability of the company to attract and retain customers. Other risk factors are listed from time to time in the company’s United States Securities and Exchange Commission reports, including, but not limited to the Annual Report on Form 10-K for the year ended December 31, 2005. Delphi disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events and/or otherwise.

Similarly, these and other factors, including the terms of any reorganization plan ultimately confirmed, can affect the value of the company’s various pre-petition liabilities, common stock and/or other equity securities. Additionally, no assurance can be given as to what values, if any, will be ascribed in the bankruptcy proceedings to each of these constituencies. A plan of reorganization could result in holders of Delphi’s common stock receiving no distribution on account of their interests and cancellation of their interests. Under certain conditions specified in the Bankruptcy Code, a plan of reorganization may be confirmed notwithstanding its rejection by an impaired class of creditors or equity holders and notwithstanding the fact that equity holders do not receive or retain property on account of their equity interests under the plan. In light of the foregoing and as stated in its October 8, 2005, press release announcing the filing of its Chapter 11 reorganization cases, the company considers the value of the common stock to be highly speculative and cautions equity holders that the stock may ultimately be determined to have no value. Accordingly, the company urges that appropriate caution be exercised with respect to existing and future investments in Delphi’s common stock or other equity interests or any claims relating to pre-petition liabilities.
