THE DOUBLE STAGE PANEL BOARD, type APR 40 PLUS, WITH AUTOMATIC SWITCH-OVER SYSTEM for medical gas is conceived and manufactured according with MDD 93/42 EEC and subsequent amendments and harmonized standards ISO EN 7396-1,EN 10524-2, EN 737-3 and according with HTM 02-01.
The DOUBLE STAGE PANEL BOARD APR 40 can be used as a primary and secondary source or, in case of presence of a main source like cryogenic tank, vaporizer, compressed air by compressors, etc can be used such as secondary source and reserve. The fi rst and second stage panel boards have the goal to reduce the pressure from cylinders (210 bar) to the in line pressure (5 or 6 bar). In these types of systems the pressure of the cylinder is directly reduced to the working pressure of the outlet installed in the hospital rooms, operating rooms etc.. In order to reduce the cylinder pressure to the in line pressure, the two-stage station is composed by one unit to reduce the high pressure and one unit to further reduce the pressure to 5/6 bar
THE FIRST STAGE panel board develops an initial reduction of the pressure cylinder to a 12 bar pressure . In case of exhaustion of the operating source the pneumatic device will automatically exchange the source providing that the pressure never falls below 10 bar. Also, when the pressure of the cylinder is below 20 bar the high pressure gauge sends a signal of empty manifold that switches on a red led placed on the central section of the unit. Please also note that the signal must also be displayed 24 hours a day in a remote controlled location. Each regulator has a 40 cu.mt/hr load at a pressure of 10 Bar
