Latest Patents

Darm's latest patents include an "Oxygen Reduction System" and a "Condenser Apparatus with Automatic Defrost." The oxygen reduction system is designed for industrial dryers and features a closed-loop gas recirculation system that utilizes both high volume primary and low volume secondary gas paths. This system incorporates a condenser apparatus to effectively remove water and solvents from the gas. A natural gas burner is employed to produce the necessary oxygen-reduced gas and energy for the dryer. The optional condenser apparatus is equipped with heat exchangers that facilitate the condensation of water vapor and solvents, ensuring efficient operation.

The second patent, the "Two-Stage Gas Condenser with Feedback Cooling," describes a method for condensing water vapor and other contaminants from hot air or treated gas. This system utilizes two heat exchanger stages and employs a cooling gas that is fed back through the cooling passages after the removal of water and solvents. The counterflow design of the heat exchangers allows for efficient operation, maintaining the temperature of the treated gas above freezing while maximizing the separation of condensed materials.
