Trent Technologies, Inc., an engineering research and development company, was founded in 1993 by Warren Trent, his brother Curtis and son Paul.

For years, air-conditioning systems at Paul’s printing company intermittently leaked condensate on to work in progress and machinery, costing thousands of dollars each episode. His father, a retired aerospace engineer, was consulted about designing condensate traps for Paul’s HVAC units. In 1986 Warren and Curtis, a retired university professor, began research for a solution.

The solution came to be known as the CostGard™ Condensate Drain Seal, which was specifically designed to remove a liquid from a pressurized chamber; CostGard™ products are engineered, manufactured and assembled in Texas, USA.
