Optimizing efficiency through Design

McDantim on-site gas blending equipment has the capability to reduce operating costs without sacrificing process quality or flexibility.  Additionally, reducing the use of premixed cylinders saves on changeover times and floor space as well as reducing the inherent safety risks of cylinder storage and handling. 

On-site mixing of bulk, mini-bulk or micro-bulk gases can lead to significant cost savings. Gas deliveries, inventory handling, and associated paperwork are also reduced.

McDantim blending panels have been in service for over 30 years, do not require electricity, and are built to perform flawlessly in any production environment.

Our blending equipment will meet or exceed AWS standards for blend tolerances at all times.
