Frese OPTIMA Compact pressure independent balancing and control valve (PIBCV) is used in heating and cooling systems with air handling units, heat exchangers or mixing circuits. Its wide differential pressure range makes it suitable for use in most applications.

Frese OPTIMA Compact combines an externally adjustable automatic balancing valve, a differential pressure control valve and a full authority modulating control valve. It has an intelligent control that automatically adjusts to the preset flow to give full modulating control and ensure there is no overflow even if pressure conditions fluctuate.

Applications

OPTIMA Compact control systems have been used in a wide variety of market sectors, including commercial office developments, hotels, educational establishments, sports complexes and residential buildings.

Typical applications include:

  • Fan coil units
  • Chilled beams (active and passive)
  • Radiant panels
  • Underfloor heating
  • Plate heat exchangers
  • Air handling units

Features

  • The presetting function has no impact on the stroke, full stroke modulation at all times, regardless the preset flow
  • Regulation characteristic remains unchanged regardless of 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
  • Motoric actuator 0-10 V and 3 point control
  • 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

Key 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 1)
  • Flexibility if the system is modified after the initial installation

Installation

  • No further regulating valves required in the distribution pipework when Frese OPTIMA is installed at terminals
  • Total number of valves minimised due to the 3-in-1 design
  • Minimised commissioning time due to automatic balancing of the system
  • Removable cartridge solution simplifies flushing procedure
  • 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
