  • includes Descaling Headers & Enclosures
  • monitors pump loading, as more pumps are loaded, flow rate increases, maintaining a higher level in the accumulator, providing more constant pressure and available fluid
  • because it provides continuous level, it reduces the required vessel size by between 15 and 30% depending on system parameters
  • designed to provide all control and safety features required for the safe and efficient operation of air/gas/nitrogen-ballasted accumulators
  • pump loading sequence is controlled for up to 6 pumps
  • incorporates discrete level and pressure switches acting directly in the pump and valve circuits to provide redundant safety
  • has microprocessor control to regulate accumulator level by sequencing loading and unloading of the pumps with relay logic back-up.
  • suitable for new or existing installation
  • system stores and records:
    • operating pressure
    • level in percentage
    • pump run time
    • pump load time
    • alarm status
    This can be transmitted for permanent storage into a main frame computer or printed-out if desired.
