Frese OPTIMA Compact DN10-DN50

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: • The wide (up to 800kPa) differential pressure range meets the requirements of most applications • The compact design and the user-friendly presetting unit guarantee easy installation and commissioning. 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 dimentioned capacity is changed. Energy saving due to optimal control, lower flow and pump pressure. Maximized ΔT due to faster response and increased system stability.

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 Compact is installed at terminals.
• Total number of valves minimized due to the 3-in-1design
• Minimized commissioning time due to automatic balancing of the system
• No minimum straight pipe lengths required before or after 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.
• Thermal actuator On/Off or 0....10V, normally closed.
• Electro mechanical actuator 0-10 V and 3 point control, normally closed
• Differential pressure operating range up to 800 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
