Stand-Alone Units

What is a Stand-Alone Unit?

A stand-alone unit – or to be correct a stand-alone terminal unit – runs like a FCU but independent of a Building Management System. The stand-alone unit works together with a self-acting thermostat which communicated directly to modulate, open or close the flow.

Stand-alone units are commonly seen in smaller buildings or remote buildings away from central control.

 

How is a Stand-Alone Unit Application Optimized?

With proper balance, a stand-alone terminal unit may maintain proper flow control and protecting the indoor climate and increasing people comfort despite the fact that it is BMS controlled. FlowCon recommends three different solutions to a stand-alone terminal unit depending on how accurate and efficient the installation should be:

  1. Pressure Independent Control (PICV)
  2. Temperature Control (TCV)
  3. Automatic Balancing (ABV)

1. Stand-Alone Units with Pressure Independent Control (PICV)

The PICV will react to system pressure changes and regulate the flow of water to required flow by adjusting the actuator position. This helps the system to be accurately controlled even with pressure changes and reduced loads.

FlowCon recommends the following PICVs:

2. Stand-Alone Units with Temperature Control (TCV)

The TCV will react to system pressure changes and automatically provide the selected max. flow independent of pressure changes. In addition, the actuator will provide ON/OFF control, securing proper thermal performance always, even at partial loads.

3. Stand-Alone Units with Automatic Balancing (ABV)

The automatic balancing valve will react to system pressure changes and limit the flow of hot or cold water to required max. flow helping the system to be accurately controlled even with pressure changes. This solution may be installed with the separate control valve.
