Variable Speed Drive Systems

Over the last few years Bridge have seen a huge surge in the popularity of Variable Speed Drive Systems, or V-Drives, also known as Frequency Controllers. Growers simply can no longer ignore the huge energy savings that can be made by installing these drives. The most common application is to install a v-drive on a heating transport pump. The V-Drives can either be controlled by the environmental computer, which calculate the energy required, and adjusts the speed of the pump accordingly. Alternatively, the V-Drive can work as stand-alone unit, which is most common when we retro fit the drives in an existing system. When installed in this way V-Drives control themselves and adjust the pump speed, based on the difference between the flow and return temperatures.
