OPTIMIZER 6-way
Pressure Independent Control Group
The Frese OPTIMIZER 6-way Pressure Independent Control Group provides complete pressure independent balancing and control for 4-pipe heating and cooling systems.
The Frese OPTIMIZER 6-way provides modulating control, which works independently of any variations in the differential pressure of the system.
The group consists of an OPTIMA Compact pressure independent control valve (PICV) with a 0-10V modulating actuator, a 6-way control valve with a rotating actuator and the Control Unit.
The Frese OPTIMIZER 6-way can be used in 4-pipe systems, such as:
- Heating and cooling ceilings
- Convectors
- Decentralised ventilation units
- Fan coil systems
- Convection heating & cooling units
Benefits
- Only one data point for the BMS needed
- Complete solution. No balancing valves required in the system
- Energy saving through optimum pressure independent flow limitation and regulation
- Modulating control for both cooling and heating
- Less time spent in selection and sizing. Only design flow and minimum differential pressure required
- Full comfort without recommissioning should the system be extended during the construction phase
- Compact solution with small space requirements
- Silent operation when modulating heating and cooling
- Stand alone or central room temperature control
- No time consuming commissioning required
- Safety function closes the modulating valve if the external input signal is lost
Features
- The pre-setting function of the PICV has no impact on the stroke - full stroke modulation at all times, regardless of the pre-set flow
- The constant differential pressure across the modulating control component of the PICV guarantees 100% authority
- Dynamic balancing eliminates overflows, regardless of fluctuating pressure conditions in the system
- Motoric on/off actuator for the 6-way and thermic 0-10V modulating actuator for the PICV
- Achieves high flows with minimal required differential pressure due to advanced design of the PICV
- Higher pre-setting precision due to stepless analogue scale of the PICV
- Ultra-high KVS value on the 6-way valve to provide minimal pressure loss
- Automatic exercising of 6-way valve once a week
- Control unit with 0-10 V DC feedback signal for modulating valve opening
