How does Powerboss stop water hammer?
Water hammer generally happens when you turn off a water flow suddenly, but can also happen when initiating the water flow. Shutting off the flow suddenly sends a pressure or shock wave down the water line through the water shocking the pipes and creating the ‘hammer’ noise. These shock waves travel faster than the speed of sound and can exert very great instantaneous pressures. Over time, water hammer can damage pipes, valves and eventually weaken pipe joints. By controlling the speed of the motor at startup and shutdown, the liquid flow is changed at a controlled pace which eliminates or greatly reduces the resulting water hammer effect. (This will greatly reduce the maintenance requirements for the pipe structure supporting the liquid flow.) Powerboss incorporates soft starting and soft stopping functionality with its unique energy savings functionality to help eliminate water hammer and reduce energy consumption. The soft stop feature of Powerboss is available in three phase units
