OPTIMA Compact

Pressure Independent Control Valve

With OPTIMA Compact you get a dynamic flow and temperature control valve for heating and cooling systems

OPTIMA Compact combines the functions of an externally adjustable dynamic balancing valve, a differential pressure control valve and a full authority modulating control valve in one single, compact valve housing.

The OPTIMA Compact provides modulating control with full authority regardless of variations in the differential pressure of the system making it possible to achieve 100% control of the water flow in the building.

In addition, the correct application of the OPTIMA Compact can significantly reduce pump energy consumption and improve the efficiency of other hydronic system components. It also provides optimal comfort for end users due to high precision temperature control.

The valve operates by adjusting automatically to the pre-set flow under fluctuating pressure conditions whilst also providing full modulating control. To achieve the design flow rate, the simple pre-setting scale on top of the valve is rotated to the required set point, which can be determined by using the Frese flow tables or the Frese Valves app.

OPTIMA Compact is also available in a Veriflow-series. This has an additional P/T plug which allows for both flow measurement and verification of minimum differential pressure across the valve. This is the first pressure independent control valve (PICV) on the market to integrate both functionalities in the original valve housing without add-ons and additional space requirements.

Frese OPTIMA

Performance beyond size

PICV - With the highest performance and best energy efficiency Frese OPTIMA is setting new control standards in heating and cooling systems.

Full modulating control and maximized ΔT

With Frese OPTIMA PICV you will get modulating control with full authority regardless of any fluctuations in the differential pressure of the system.

Maintaining optimal control, lower flow and lower pump pressure means great energy savings. At the same time you will maximize ΔT due to a much faster response and an increased system stability.

An always balanced system means great energy savings

Frese OPTIMA PICV makes it simple to achieve 100% control of the water flow in the building, while creating high comfort and energy savings at the same time. No balancing is required if further stages are added to the system, nor if the dimensioned capacity is changed.

Pressure independent balancing & control valve

Frese OPTIMA PICV combines an externally adjustable automatic balancing valve, a differential pressure control valve and a full authority modulating control valve. Used in heating and cooling systems Frese OPTIMA (PIBCV) fits applications with air handling units, heat exhangers or mixing circuits.
