"GAS-CHEX" consists of a series of no charge Plant Inspections and Seminars designed to assist in making your operation safer, more cost-effective and more efficient.

Factory experts are available to assist us with our GAS-CHEX program for every product line we carry. We have hundreds of videos available on everything we distribute in addition to safety training. We bring the seminar to you plus we offer Welder Training Schools in our Wilmington Training Center.

We will visit your facility with the relevant experts to observe your equipment in operation. We will analyze each step in your operation for safety and efficiency. This includes evaluating volumes of gases used versus the mode of use. We will observe gas purity use to determine whether the same results could be achieved using a less costly gas. Keen will then prepare a written GAS-CHEX report outlining our recommendations for cost savings and suggestions for general improvements within your operation.

We will provide Safety Education for you and your Associates. We will design custom Safety Seminars to meet your particular needs. At the completion of the Safety Education program we will provide you a written report outlining specific training performed including comments and recommendations for improvement in this area.
