Is there a need for a pump to privide fexible expansion coupling in suction and its discharge. What are the parameters should I consider in providing this flexible coupling.Tnx
I have a room protected by FM200, since this is a clean agent and not harmful to the health is it really need to provide ventilation after the discharge, because we are mandate to provide ventilation and compute for the time needed to exhaust the discharge agent.please help.thanks.
