The various VariStream Auto-Compensating Flow Controller gives waterfed pole users a sophisticated electronic flow adjustment to allow them to regulate their water flow during the cleaning process.
The VariStream 2 unit can be retrofitted to virtually any water fed pole window cleaning system which uses a 12vDC pump to deliver pure water to the end of the telescopic pole.
Once installed, the VariStream 2 does away with the functionality of the pressure switch on the pump, and digitally controls the electrical supply to the pump. This allows a full range of water flow rate adjustment from maximum all the way down to zero. The user simply dials in their preferred water flow rate on the VariStream 2 and can then start work cleaning windows.
The inbuilt "Auto Compensating" software is continually sensing the load on the pump and adjusting the output of the of the pump to ensure that precisely the required amount of water is delivered to the end of the pole. With a standard pump, as the water fed pole is extended for higher windows, the load on the pump increases and the amount of water at the end of the pole decreases. VariStream 2 compensates for this automatically, ensuring a constant and controlled flow of water, whatever height you work at.
VariStream 2: The Benefits
Total control over the flow of water from the end of the pole. Whatever height you work at VariStream 2 adjusts the pump to compensate and maintain flow.
Auto shut off: When you disconnect the pole at the end of the job VariStream 2 detects pressure change and shuts off the pump, saving water and battery life.
Water saving is essential when you are working far from your source of ultrapure water. Varistream 2 allows you to control your water consumption to ensure your water lasts until you return to base at the end of the day for a refill.
The pressure switch is the main wearing part on any water fed pole pump. By eliminating use of the pressure switch, the VariStream 2 improves pump reliability meaning less time spent servicing your equipment.
The majority of water fed pole systems use a tank of filtered water on a vehicle plus an additional ion-exchange resin cartridge which "polishes" the filtered water to further reduce contaminants. By allowing controlled reduction of water flow through the system the VariStream 2 improves the life of the expensive resin cartridge, thus saving the operator money on a daily basis.
