Mechanical systems in healthcare facilities are unlike any other systems. Even the person who brazes the copper tubes of medical gas systems must have special ASME qualifications. The alloy of copper itself is special as is every fitting. The HVAC units must have precision temperature/humidity control ability for use in surgical suites that employ lasers. This is high-level systems work and only companies such as KMI, the top echelon of designers and installers, are qualified, licensed and certified to do the work.
