In the 1970s, the company focused on selling a growing array of gloves and safety equipment to companies around the world. In the 1980s, he began bringing complimentary quality safety companies into Wise El Santo, which continues to today.

In-House and Field/Mobile Service Centers*

Our service centers underscore our commitment to customer satisfaction. Instruments and other items require regular maintenance for reliable operation. To offer improved service, we established field service, mobile service and in-house repair facilities complete with all the necessary diagnostic equipment. Our experienced service staff will keep instruments and breathing air equipment functioning correctly longer. We are capable of handling a customer’s needs from specialized calibration kits to board level repair and SCBA rebuilds.

With our stock of vital parts, and experienced factory trained technicians, downtime is kept to a minimum. We maintain a repair history of every item that comes through our repair system. Each customer receives a detailed printout of repairs and parts used with their returned product.

Companies with SCBA’s and instruments are often reluctant to send equipment away for service. Their fear is to have an emergency without enough equipment to respond. We have solved this concern by developing mobile repair trailers. Our trailer can be brought to any location for on-site product repairs. The SCBA’s and instruments are immediately available in the event an emergency arises.
