DEOXO & ADSORPTION DRYERS
MODULAR SYSTEM
AQUAGAS offers advanced adsorption dryers, deoxidizers, and filters for the purification of gases such as hydrogen, oxygen, helium, air, and more.
Traditional gas purification technologies that rely on adsorption typically result in a gas loss of 5-20%. AQUAGAS has developed a durable, proven, and cost-effective solution (model DR) that purifies gas without any gas loss—and without the need for any moving parts or bearings.
Our modular system includes pressure vessels, condensation units, piping, heaters, coolers, and more, allowing for a flexible and efficient design of purification systems tailored to meet each customer’s specific requirements.
