Our Products

We are the industry standard for Gas Abatement


The Marathon 8500 is an advanced, point-of-use, integrated burn/wet treatment system designed to provide a controlled gas conditioning environment for today’s demanding semiconductor and flat panel display process chemistries.


Guardian systems are designed to thermally oxidize spent process gases using active flame oxidation. The effluent gases pass through a wall of flame in the main chamber, guaranteeing ignition of flammable and pyrophoric process gas by–products.


The Vector is a proven solution for a variety of processes including Etch and Epi. An extensive database of applications and removal efficiencies is used to customize the best solution for a given process.

CDO 863

The CDO™ series is an advanced point–of–use integrated thermal-wet treatment system designed to provide a controlled gas conditioning environment for today’s demanding semiconductor process chemistries.

The only place where you’ll get the perfect solution.

Industries We Serve!

The flat-panel display is used in film, etching, doping, vapor deposition, diffusion process. There is about 50 different types of gases used in this process

The IC manufacturing produces the most toxic and harmful gases among all the steps in the process
