The review follows efforts by CSE to incorporate customer feedback on respirator products, implement performance improvements as well as technological improvements for miner safety, CSE Corporation president Scott Shearer said.

“The quality of the new SRLD is unmatched. Once in the field, it will be the smallest, lightest, fastest working unit available in its class,” Shearer said.

“The development process for the new SRLD has been extensive and has spanned more than a decade and numerous prototypes, thousands of man hours and investment to develop this vital rescuer device.”

The product’s technology is contained in a lightweight package, and includes an oxygen starter unit designed and manufactured by compressed gas cylinder supplier Leland.

The SRLD offers a 40% faster production of oxygen at the start up, as well as a 10% total increase in oxygen production.

Shearer said the SRLD produced more oxygen more quickly to the miners who needed it.

“Having easy accessibility to our vendors and suppliers has been a huge improvement in the development of this new SRLD product,” he said.

“We have partnered with Leland Limited, Inc, the world leader in production of small compressed gas sealed cylinders for supply of the starter oxygen in these new units.

“The unprecedented quality of this product will instill even more confidence in its dependability by the miners using it.”

The SRLD includes an irreversible seal indicator, noting breach of water vapor or moisture, as well as a temperature indicator, to guide miners and users upon inspection as to what units should be removed from service.

“CSE has pulled out all of the stops to develop what we know will be the best operating unit with the highest quality performance for the mining industry,” Shearer said.

“This product is designed with both miner safety and miner convenience in mind.”
