OPTIMA Compact actuators

DN10-DN50

Actuators

DN10-DN32

Proportional 0-10V or 3-position modulating or On/Off control of Frese OPTIMA Compact valves in heating,ventilating and air conditioning systems.

The actuator can be mounted on the valve by hand and without the need of a specific tool.

Due to the compact design of the actuator, it is particularly suitable for installations where space is limited.

LOGICA Digital

Energy-series, DN10-DN80 (DN100 Ultra)

The LOGICA Digital Energy series is a digital actuator designed to optimize energy usage in Heating, Ventilation and Air Conditioning (HVAC) systems.

Paired with an OPTIMA Compact valve, it offers intelligent hydronic control and insight.

The actuator simplifies system integration from easy installation to direct communication with the Building Management system (BMS) to selectable control methods to suit different applications.

Built-in energy management algorithms and functions greatly reduce system integration hours.

Failsafe & Feedback actuators

DN10-DN32

Proportional 0-10V modulating control of Frese OPTIMA Compact valves in heating, ventilating and air conditioning systems.

The actuator can be mounted on the valve by hand and without the need of a specific tool.

Due to the compact design of the actuator, it is particularly suitable for installations where space is limited.

0-10V feedback signal for indication of stem position of the PICV.

Thermostat with remote sensor

for water and air

Thermostat with M30 x 1.5 connection suitable for Frese OPTIMA Compact with 2.5 mm stroke.

The thermostat is a self acting proportional controller for temperature control applications including fan coil units, hot water tanks and heat exchangers.

The remote sensor can be directly immersed into the medium or alternatively a sensor immersion pocket can be supplied separately as an accessory

Modbus actuators

DN10-DN50

The Frese Modbus Actuator is designed to be used with the Frese OPTIMA Compact valves in heating, ventilating and air conditioning systems.

The actuator can be mounted on the valve by hand and without the need of a specific tool.

Due to the compact design of the actuator, it is particularly suitable for installations where space is limited.

Spring Return actuators

DN40-DN125

Spring return actuator proportional 0-10V or 3-point floating modulating control of Frese OPTIMA Compact valves in heating, ventilating and air conditioning systems.

Due to the self adaption of stroke length, the actuator provides full utilization of the OPTIMA Compact valve modulation.

Can be supplied for Frese OPTIMA Compact PICV valves (DN40-DN125)
