Praxair, Inc. has entered an agreement with Integrated Automation Systems, Inc. to market the breakthrough OptiGas gas-filling system for insulating glass in windows and doors.

With conventional gas-filling systems, the largest cost factor is the gas lost during the fill. It usually measures between 40-70% loss. Through a proprietary filling process, the patent-pending OptiGas system injects the precise amount of krypton, argon or a mix of both into the insulated glass unit at a controlled flow rate to eliminate losses.

According to Praxair, the OptiGas system can reduce krypton consumption by up to 70% per unit. Another feature of the OptiGas system is the ThermalCert module which can analyse the gas in the windows or doors, providing gas content verification.

Praxair and Integrated Automation Systems will be introducing the OptiGas filling system at the GlassBuild America Expo in Atlanta, Georgia. The event takes place from 12th-14th September.
