Variable Speed Control

REDUCE ENERGY USE WITH A VARIABLE SPEED CONTROL

The key to reducing wear and tear on your vacuum pump motor is to run it at the slowest speed necessary to provide the air volume needed. BouMatic’s VSD manages your vacuum pump so it supplies all the air your system needs, but at much more efficient, cost-saving level. Conventional, fixed drive vacuum pump systems have only a full-on or full-off setting.Air demands in a milking system vary widely throughout the milking cycle.

The BouMatic VSD uses a special sensor to monitor vacuum levels in the system. This sensor knows when more air is needed and will increase the output of the vacuum pump, but only enough to maintain the required airflow. Once the desired volume of air is reached, the VSD will decrease the air output by slowing the vacuum pump. The BouMatic VSD maintains the perfect vacuum balance for milking, washing or other vacuum requirements.

Recent scientific research has determined that the amount of air-flow actually used for "steady state" milking - when all milking units are attached without any squawking teat cups or air leaks - is as little as 1 to 2 cfm (30 to 60 L/min) per unit. There are times during milking when additional airflow is required, such as when attaching units, when there is a squawking liner, or when a milking unit falls off. There are also times during the cleaning of the milking system when additional airflow is needed, such as when an air injector admits atmospheric air into the milk line to form a "wash slug". A BouMatic Variable Speed Drive is the way to achieve the correct amount of air-flow for your system.
