NOVAIR MEDICAL AUTOMATIC CHANGE-OVER MANIFOLD
Ensuring the continuous supply of medical gas piping network
MEDGAS BANK Automatic changeover cylinders are designed for healthcare facilities wishing continuously supply oxygen, nitrous oxide, compressed air, nitrogen or carbon dioxide, their distribution of medical gases from cylinders or bundles .
The range of Novair Medical cylinders meet capacity requirements from 40 to 90 m3/h, and works with groups of minimum 2x1 cylinder.
Working principle of an automatic change-over manifold
MEDGAS BANK is connected to two different power sources called primary and secondary source. It is equipped with valves that reduce the variable pressure in medical gas cylinders at high pressure. The valves are designed and tested for pressures above 400 bar. The inverter mounted on the control panel allows switching between two sources, usually composed of groups of cylinders.
Composition of MEDGAS BANK automatic change-over manifold
MEDGAS BANK automatic change-over manifold is composed of :
Automatic control panel, fully mechanical (no electricity needed) and mounted on a steel skid. It is composed of two high pressure valves according to EN ISO 10542-2, 1 high pressure switch chrome plated, 2 high pressure isolation valves, 2 low pressure isolation valves, 1 pneumatic inverter, 2 manometers 0/16 bar (low pressure), 2 manometers 0/315 bar (high pressure), additional safety valves to prevent dangerous pressure in the distribution network
Rack: including restraining chains, attached to the wall to hold the bottles
Cylinder ramp : wall mounted to hold the pipe, the stop vavles and the flexibl tubes (connection gear)
Stop vavles : isolates each flexible tube and cylinder pipes (network)
Complete stop vavles of the ramps : isolates each cylinder/source ramp (left or right) of the system / network
Relief valve: drain / purge each cylinder ramp separately
Flexibl tube/connection gear : connects the pipe to gas cylinders
Filters: protects the system against dust from gas cylinders
Heater (only for N2O at flow rates) preheats the gas in the stage of high pressure
Gas cylinders upon request (option)
