What is the difference between VAV and CAV? What does Constant Pressure Control involve?When desgning a ventilation system, we often come across the terms "VAV", "CAV" and "Constant Pressure Control". In this article I would like to explain what these terms mean exactly, when which option is used and what you need to pay attention to when designing and adjusting an automated ventilation system.>>>

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.>>>
