Brownies Tankfill Indroduces State-of-the-Art Digital Frequency Drive.

Business Editors

SARASOTA, Fla.--(BUSINESS WIRE)--May 3, 2004

United Companies Corporation, (OTCBB: UCPJ) announced today that its Brownie's Tankfill Division is now including a Digital Frequency Drive Package as standard equipment on all models of their popular Yacht Pro series compressor systems.

Most boaters are keenly aware of the current or draw required by most major components onboard a vessel. The initial spike demanded by some systems can be more than eight (8) times the draw during normal operating conditions; so high that the operator may even need to turn off one or more appliances in order to allow a heavy draw system to start up. This "trading-off" of components can be confusing and tiresome.

The Digital Frequency Drive package now featured on the Brownie's Yacht Pro series compressors completely eliminates the start-up spike by gradually ramping up the motor speed. The draw never exceeds that of normal operating conditions. The result is substantially less demand on the boat's electric system and greater efficiency for the compressor.

In addition to the Digital Frequency Drive, Brownie's Yacht Pro compressors offer other advanced features to specifically address the needs of the boating diver. All compressors are mounted on rustproof stainless steel frames with vibration isolators for the smoothest, quietest operation possible. Each compressor is precisely controlled by a programmable solid-state pressure switch, which monitors the amount of air in the tanks as they are being filled. When the tanks reach the programmed setting, the entire system automatically shuts down to conserve power and avoid overfilling. The operator can monitor the process at any time on a digital display. All hardware, fittings and connectors are also exclusively stainless steel for years of dependable service in a marine environment.

Brownie's Chief Executive Officer, Robert Carmichael states, "This is just one of the many innovations Brownie's has implemented to make diving from boats and yachts easier and more enjoyable. It will dramatically lengthen the life of the compressor system as well as increase the efficiency of the vessels electrical system."

United recently acquired 100% of Trebor Industries, Inc. the manufacturer of all the Brownies line of products. In the most recent fiscal year, the Brownies line totaled approximately two and a half million ($2,500,000) in annual sales.
