Thermodynetics Reports Annual Results. Turbotec Products Plc Subsidiary Appoints Two Independent Directors

Wednesday, June 28th, 2006

THERMODYNETICS, INC., WINDSOR, CT (TDYT:OTCBB)

The year ended March 31, 2006 was notable in that our Turbotec subsidiary achieved record revenues and expectations for the 2007 fiscal year is for further growth. At the same time, the Vulcan Industries subsidiary was closed due to a number of factors and Vulcan is now reported as a discontinued operation in the financial statements.

On a continuing operations basis, the Turbotec subsidiary is growing. Turbotec is well financed having raised equity capital through an IPO on the London Stock Exchange’s AIM Market and is trading under the symbol TRBO. Turbotec is expecting to demonstrate continued growth in both revenues and profitability.

The expectation for the ‘07 fiscal year is that new product launches will begin to capitalize on the company’s technology and apply it to “green” applications and other sophisticated heat transfer applications using titanium and other surface enhanced tubing. Initial products are being developed for the reclamation of waste energy from air conditioning, refrigeration and heat pump systems so that the reclaimed heat can be recycled and used for a variety of purposes. Turbotec believes that this is a major market and with the high cost of energy, it is an opportune time to market such energy savings products.

In fiscal ‘06, net revenues advanced 20% to $18.750 million from $15.651 million in fiscal 2005 while, on a continuing business basis, income from operations advanced to $1.2 million vs. $0.8 million, a 50% increase and pretax income was twice that of the prior year.

At this writing, based on the 12,806,773 shares of TRBO outstanding, the market value of TRBO is in excess of $20 million, corresponding to TDYT having a value for the TRBO 56.32% holding alone of $12 million, or approximately $3/share. The calculation is based on an exchange rate of US$1.84 for each UK pound sterling, and 4.027 million shares of TDYT outstanding.

Two independent directors to represent the British subsidiary have been appointed. Tom Nairn is the new Chairman and he is joined by Robert Lowe, both of whom were appointed on June 20, 2006, and both of whom are UK based. That brings the Board to 5, as Anthony Mirabella, Sunil Raina and Robert Lieberman are the existing board members. Their resumes are included in the Turbotec press release that can be viewed on the web site www.turbotecproducts.com. It is anticipated that by rounding out the board with Messrs Nairn and Lowe, because of their familiarity with Turbotec’s business base and the business climate in both the US and Europe, they will help Turbotec to expand both in the US and in Europe.

TRBO’s business is expanding in the areas of swimming pool heat pumps, ice machines and boiler tubing. They have bolstered their staff with new senior managers in Sales and Marketing and Product Engineering. Additions to staffing are continuing with the intent of supporting the growth of the company and to concentrate on continuing improvement in operations, engineering and customer support.
