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.

Benefits

Design

• Less time to define the necessary equipment for a hydraulic balanced system (only flow data are required)
• No need to calculate valve authority. Always one.
• Flexibility if the system is modified after the initial installation

Installation

• No further regulating valves required in the distribution pipework when Frese OPTIMA PICV is installed at the units.
• Total number of valves minimized due to the 3-in-1 design
• Minimized commissioning time due to automatic balancing of the system
• No minimum straight pipe lengths required before orafter the valve.

Operation

• High comfort for the end-users due to high precision temperature control
• Longer life due to less movements of the actuator

Features

• The presetting function has no impact on the stroke; Full stroke modulation at all times, regardless the preset flow.
• The constant differential pressure across the modulating control component guarantees 100% authority.
• Automatic balancing eliminates overflows, regardless of fluctuating pressure conditions in the system.
• Electro mechanical actuator 0-10 V and 3 point control.
• Differential pressure operating range up to 600 kPa
• High flows with minimal required differential pressure due to advanced design of the valve
• Small dimensions due to compact housing
• Higher presetting precision due to stepless analogue scale
