Who We Are

Trent Technologies, Inc. is an engineering research and development company incorporated under Texas USA laws. We research, develop, manufacture, market and distribute all our products. Our most popular product is the CostGard™ Condensate Drain Seal, an advanced-design component for HVAC systems. It replaces the failure-prone condensate p-trap. It solves all the problems it creates by using air as a seal in place of water. It is a unique technological development that ensures reliable condensate drainage from any air conditioning system. It provides a drain seal during all operating conditions, heating, and cooling, preventing contaminated outside air ingestion. It is self-cleaning, self-regulating, has no moving parts, and requires no maintenance. It exceeds the industry’s minimum standard outlined in any code. It improves indoor air quality, IAQ, by keeping the unit dry inside. It prevents water damage to equipment and buildings, offering building owners a proven path to significant saving and greater profits. Tens of thousands of CostGard™ Condensate Drain Seal systems are in use worldwide. There have been no failures in 30 years. For more than two decades, one company installing our system now has more than 9,000 stores (with over 50,000 units.) The savings in maintenance alone pays for the system in less than one year.
