Dewar changeover systems provide a continuous, uninterrupted flow of liquid nitrogen to the use point. When the primary source is empty, the system allows a simple switchover to a standby, full, secondary supply bank, thus eliminating liquid supply interruption.
CSM Cryogenic provides two options for dewar switchover system: Manual or Automatic
Automatic switchover stations will constantly monitor the liquid nitrogen supply using a liquid detection sensor. When the sensor detects liquid nitrogen supply interruption due to an empty dewar, the controller will command the vacuum-insulated valves to perform the supply switchover to the standby dewar.
Switchover stations are an efficient and economical alternative to installing a bulk storage tank with extensive vacuum-insulated pipelines.
