HVAC sensors monitor indoor air quality. Based on specific measurements supply and exhaust fan speed is regulated to guarantee sufficient fresh air supply and to optimise the energy efficiency of the ventilation system.
Indoor air quality Indoor air quality is very important to a company. Poor air quality costs a company money. It leads to increasing health problems amongst employees, resulting in higher absenteeism due to illness. Ventilation is necessary to guarantee good indoor air quality. That is why fresh air supply in the Sentera factory is continuously monitored and logged. When there is activity at the production site, the indoor air quality decreases. People on the work floor produce CO2, the plastic injection machines produce VOCs and the relative humidity can fluctuate.
Demand based ventilation Air Handling Units are installed next to the factory to supply fresh air. Fresh outside air is cooled during summer and heated during winter by means of the extracted indoor air. During exceptionally warm days, extra cooling can be provided. It goes without saying that during such days a lot of energy is required to cool the fresh outside air before it can be supplied into the factory building. CO2 sensors and air quality sensors in the air ducts monitor the quality of the extracted indoor air. Supply and exhaust fan speed is controlled in function of the measured indoor air quality. This demand-based ventilation ensures the supply of sufficient fresh air. When the indoor air quality is sufficient, the supply of fresh air is reduced to save energy. The air volume that is supplied to the building is monitored on a continuous basis by differential pressure sensors.
Monitor fresh air supply via SenteraWeb The different HVAC sensors and fan speed controllers are connected to SenteraWeb via an internet gateway. SenteraWeb is the online HVAC platform for remote control, monitoring and data logging. Both Sentera devices and registered non-Sentera devices can be connected to SenteraWeb. All measured values can be visualised and parameter settings can be adjusted. In case threshold values are exceeded, a notification or warning is sent via email or text message. The day-week schedule enables to optimise the ventilation system in function of the planned activities.

Today, the Sentera group counts 8 companies and 150 employees based in 4 different locations. Headquarters and the central warehouse are located in Temse, Belgium. Sentera is a 100 % family owned group of companies. For more information, contact Sentera!
New Sentera product catalogueSince 1997, Sentera has been a leading manufacturer of fan speed controllers for ventilation systems. However, over the past decades, Sentera has also invested heavily in the development of control systems, sensors and Modbus network equipment. All these individual devices are excellent examples of Belgian top technology. However, combined in our Sentera Solutions, they form high-performance control systems for the most diverse ventilation applications.>>>
CO poisoning in parking garagesCarbon monoxide (CO) is a colourless, odourless and tasteless gas that mixes with normal air. It remains present for a long time and does not break off spontaneously. Inhaled CO is absorbed into the blood through the lungs, just like oxygen. This disrupts the transport of oxygen to the cells and causes a lack of oxygen.>>>
What are 3-speed control switches and how do they operate?Many motors today are designed to be as flexible as possible when it comes to speed. A three-speed motor has three field windings and a rotor, all in one housing. Each field winding is designed to spin the rotor at a different speed. This enables one motor to be used for a number of different applications. A three-speed motor usually has four wires, the three speed wires and the common wire. Power is supplied to the common wire and any one of the speed wires for a certain speed.>>>
Sensors for demand based ventilation systemsWhich sensors should I use in my building? This is the question that is regularly asked these days with most people spending up to 90 % of their time indoors. Due to Corona and the ever-improving insulation of our buildings, the importance of good ventilation is becoming increasingly clear. Along with this advancing insight, additional questions arise.>>>
