Optivent® System

Optivent® Basic and Plus will give you low operating costs over time

The Optivent® integrated system minimises energy consumption whilst providing a controlled supply of conditioned air to maintain pre-set CO2 levels and a user-defi ned temperature, delivered quietly, without draughts.

The air that we breathe out makes humans the largest source of carbon dioxide (CO2) inside a room. For this reason, the level of CO2 in a room can be used as a reliable indicator of the loading and, as a result, the air quality in a room. An increase in the number of persons in a room also causes an increase in the level of CO2, and conversely the level of CO2 falls proportionally as the number of persons in a room decreases.

Dynamically varying the air flow according to the actual loading, based on temperature, occupancy, CO2 level or a combination of these parameters, brings several advantages.
You can ensure good air quality and a comfortable indoor climate at the same time as you avoid unnecessary ventilation and save energy as a result.

Selecting an appropriate control methodology

Temperature regulation
Suitable for premises with a high occupancy level and a uniform loading.
Via the integral temperature sensor or STRZ-05 external temperature sensor, a pre-set temperature is maintained in the room regardless of the loading.

Occupancy regulation
Suitable for premises with a low or variable occupancy level and a uniform loading.
Equipping the regulator with an occupancy sensor STRZ-09 provides a function in which the regulator regulates the temperature when someone is present in the room. When the room is unmanned, the regulator switches to an economy mode and produces a saving in energy.

CO2 regulation
Suitable for premises with large variations between high and low loading by persons who are present.
Supplementing the system with an STRZ-18 CO2 produces a function in which the regulator increases the ventilation fl ow if the CO2 level exceeds a pre-set maximum threshold value. A good air quality is assured in this way regardless of the loading, at the same time as unnecessary ventilation can be avoided.

  Air volume controlFlow variators are products for the control and adaptation of airflows in VAV (Variable Air Volume) systems. The system saves costs and energy because the flow and cooling effects are adapted to the actual demand in the room, with the result that the total flow for the air treatment units is reduced.
