you can request onsite one time ASME certification, same as is needed for Carl, Holstein and other German manufactured stills, they require pressure test report for the vessel and installation of ASME certified safety valves. 15psi is considered inherently safe, and in most districts steam piping and permits can be handled by a regular plumber. all our systems are tested to 60 psi and are rated for 45 psi steam. Having contacted ASME for certification, we were told there is no classification that we require certification under, merely registration.
we are registered with TTB and FDA as manufacturers of distillation systems.
