PSMOSHA and the EPA require that any facility that has 10,000 lbs. or more of ammonia inventory in their system have in place a Process Safety Management Program (PSM), and a Risk Management Plan, (RMP). Those with less than 10,000 pounds have specific responsibilities to maintain a safe system as outlined in the General Duty Clause. 

The Louis A. Roser Company can fully develop a comprehensive PSM, RMP, or General Duty Clause plan tailored to fit your facility.

DesignWorld-class design, consulting, and engineering.

L.A. Roser has a long history of engineering excellence. Our design team of registered professional engineers is able to take a project from its inception and follow it through to reality, utilizing the latest technology and energy saving solutions.

We are highly qualified to design for new construction, expansion projects, retrofits and system upgrades. Our business demands modern designs and attention to detail, because each refrigeration system is unique. Our in-house design professionals work closely with our customers to deliver a quality customized system that is flexible, economical and efficient, with energy saving solutions that save them money year after year.


InstallationOur construction crews offer the highest quality installations available. We go above and beyond the standard codes, and make every system tough enough to withstand years of use.

We employ highly skilled and qualified welders, pipefitters and foremen to complete all of our installations. We ensure that every weld on every pipe is the highest quality we can offer. All of our welds follow AWS D10.9 and B31.5 codes.

Our standard piping materials include carbon steel (A53 and A106) for refrigeration, A333 carbon steel for low-temperature applications, stainless steel (type 304 and 316) for sanitation and aesthetics, aluminum (evaporator coils), galvanized carbon steel, and PVC for water piping.

Outside of refrigeration, we are able to do almost any type of piping available, including (but not limited to): steam, air, glycol, CO2, high pressure, and gas lines. If you need a pipe weld done, we can complete it with ease.
