Just as winter is approaching, the current unprecedented energy prices are forcing us to use our energy even more consciously and efficiently. The most obvious measure is to lower the room temperature in our buildings. After all, if the thermostat is set a few degrees lower, a considerable saving will already be realized. However, in rooms with high ceilings, additional savings can be achieved through destratification.
Warm air is lighter than cold air and therefore rises to the ceiling. In this way, the heavier cold air is diverted to the floor. In buildings where the air is stratified, temperature differences of 1.5°C per 30 centimeters are not uncommon. In exceptional circumstances, even temperature differences of 10 °C are measured at a height difference of only 1 meter.
Stratification energy guzzler In case of stratification, the room thermostat will therefore not be able to take into account the actual thermal energy present. Consequently, there will be excessive heating, leading to unnecessary energy wastage. This phenomenon mainly occurs in buildings with a ceiling height of 6 meters or more. This mainly concerns industrial buildings, showrooms, sports halls and event halls. Stratification is considered one of the biggest energy guzzlers in HVAC. Destratification consists in bringing the layer of warm air that is against the ceiling back down. As a result, the thermal energy in the room is redistributed evenly. This leads to a higher comfort for the residents without the need for extra heating.
Energy saving of 23.5% Destratification is achieved through the use of ceiling fans that bring the warm air down again. The temperature difference is determined on the basis of temperature measurements on the ceiling and on the floor. From a temperature difference of 3 °C, destratification will result in considerable energy savings. During experiments in a room with a ceiling height of 6 meters, an energy saving of 23.5% was achieved by means of axial destratification.
Monitor and adjust the installation The TCMF8 is Sentera's latest speed controller that can control up to two AC fans based on 2 temperature measurements. This speed controller can be combined with 2 DTS temperature sensors (temperature measurement on the ceiling and on the floor). This combination makes it possible to optimally control destratification fans. In addition, the TCMF8 can be supplied as standard with a Sentera gateway (TCMF8-602EW) that makes it possible to monitor and adjust the installation remotely via Senteraweb.
Sentera's ECMF8 has been specially developed for EC fans and offers the same functionality as the TCMF8. The ECMF8 is also available as standard with a Sentera gateway (ECMF8-AO –EW).

Temperature based air control in shipsThe design of the electronic speed controller GTE21-60-DM is based on years of experience in temperature control in greenhouses and other agricultural applications, combined with an innovative electronic technology. >>>
Global warming and energy efficiencyAlthough summer should be a time of relaxation, this summer seems to confront us with the harsh reality at an unprecedented pace. There is definitely something wrong with our climate and we need to act quickly. The extreme drought threatens to make the Rhine unnavigable and the capacity of some nuclear power plants is being reduced due to a lack of cooling water. In Spain, the use of air conditioning and heating is being restricted, while the war in Ukraine threatens to jeopardize energy supplies over the coming winter.>>>
Ventilation systems in the catering industrySummer has finally arrived and soon we will all be leaving for our favourite holiday destination. After an intensive day of vacation, we often like to put our feet under the table in an authentic local restaurant to enjoy the local specialties. As soon as the fragrant dishes appear on the table and stimulateour senses, we realize (as an HVAC professional) that the kitchen is most likely equipped with an efficient ventilation system.>>>
The advantages of a potentiometer with Modbus RTUPotentiometers with minimum and maximum limit, working from low to high speed or vice versa, with 0-10 volts, 0-20 mA or PWM output, infinitely adjustable or with adjustable steps (…) were already part of our assortment. Today we have expanded our potentiometer family with the SDP-M010 series that are equipped with Modbus RTU. As a result, not only are the settings available via the Modbus registers, but from SenteraWeb or your Building Management System you can also read the position of the potentiometer and even overwrite the output.>>>
