Natural Gas Booster Built-in UPS Maximizes Availability in Emergencies

| Editor: Dr. Jörg Kempf

The Spencer Turbine Company’s GasCube skid-mounted natural gas booster is now available with its own emergency generator, allowing the unit to function as a stand-alone uninterruptible power supply (UPS).

The UPS provides instant protection from momentary power interruptions; during longer outages it can power equipment until an auxiliary power supply can be turned on, grid power is restored, or equipment is safely shut down. The original Spencer GasCube series of packaged boosters raise natural gas pressure by up to 20 kPa at flowrates up to 73,000 m3/h to supply equipment such as boilers, furnaces, water heaters and space heaters in applications where the existing mains gas pressure is too low. The compact units (914 mm wide x 1,270 mm wide x 1,930 mm high) are supplied pre-wired, pre-piped, and factory tested. At the heart of the GasCube is a sealed unit comprising a multistage centrifugal compressor with an explosion-proof motor cooled by the incoming natural gas. For applications requiring a lower gas flowrate than the rated capacity of the GasCube, Spencer can install a recirculation loop with an air-cooled heat exchanger. The GasCube is controlled from a PLC panel, housed in a weatherproof NEMA 4 cabinet, which monitors flowrate, motor current, and motor temperature. Spencer manufactures a wide range of other blowers, compressors and vacuum systems.
