Frese OPTIMA Compact

Frese OPTIMA Compact

Pressure independent control valve

Designed to combine automatic balancing and full modulating control regardless of the preset flow.

The innovative design of Frese OPTIMA Compact introduces an intelligent control valve that adjusts automatically to the preset flow in order to provide full modulating control. When the installer presets the valve according to the maximum designed flow, the stroke of the control valve remains the same thus providing 100% modulating control.

In practical terms, Frese OPTIMA Compact ensures that there is no overflow and that below the design flow the actuator has absolute authority. Furthermore, Frese OPTIMA Compact combines all those features that are necessary to ease the work of designers and installers:

Frese OPTIMA Compact pressure independent control valve (PICV) is used in heating and cooling systems with Fan Coil Units, Chilled Beams or other terminal unit applications. Frese OPTIMA Compact provides modulating control with full authority regardless of any fluctuations in the differential pressure of the system. It combines an externally adjustable automatic balancing valve, a differential pressure control valve and a full authority modulating control valve. 100% control of the water flow in the building is achieved easily, while creating high comfort and energy savings at the same time.

An additional benefit is that no balancing is required if further stages are added to the system, or if the dimensioned capacity is changed. Energy saving due to optimal control, lower flow and pump pressure. Maximized ΔT due to faster response and increased system stability.
