Energy savings of up to 20% are easily achievable. The flexibility of the design means that the system can control between 1 and 12 condenser fans, can be fitted directly to the existing condenser and does not require connection to any existing site control systems.

Operation Overview

The VSDM will always maintain the lowest discharge pressure possible in relation to the ambient temperature. It will also maintain the lowest TD possible, ensuring the system is operating at its most efficient at all times. There is a built-in minimum discharge pressure set-point to ensure that there is always sufficient discharge pressure for the system to operate.
