Battery Watering Valves

RBS Exclusive:  Flow-Rite SPWS for Locomotive Batteries

Frequent locomotive starts demand aggressive charging which results in increased water use within the batteries. Maintaining the proper level of water is essential to ensure cranking amps are available. The Flow-Rite single-point watering systems are designed specifically

  • to survive the extreme temperatures and vibrations onboard locomotives
  • to work on ALL MAJOR BRANDS of locomotive starting batteries
  • to fit within the battery compartments on locomotives
  • to ensure each cell receives the accurate amount of water

With over a decade of success on locomotives traveling across the US and Canada, the Flow-Rite single-point watering systems have been proven highly effective at reducing battery maintenance time/cost and improving battery performance. Flow-Rite SPWS may be purchased through RBS for easy install by railroad maintenance crews. They can also be factory-installed when ordering new GNB locomotive starting batteries KDZ501-FR and KDZ651-FR.

Canadus Locomotive Battery Desulfator

Safe, proven and patented High-Frequency Battery Energizing (HFBE) technology that combats battery failure by eliminating sulfation problems, the primary reason for battery deterioration. Easy to install and use; no special tools are required. When batteries are charging, Canadus battery energizers draw energy from the charger (DC side) and automatically work to keep the battery plates clean.

  • 32V & 64V
  • Reverse polarity protected
  • Operating Temperature: -45°…+85°C
  • Green LED indicator
  • M10 (3/8″) ring terminals
