Heating, ventilation, air conditioning: Designing more efficient extraction systems using differential pressure measurement
When optimising CO2 emissions, people in industry mainly consider heating, cooling, and compressed air systems. Extraction equipment along with dedusting and waste gas purification units are critical systems in production sites that generate high levels of emissions as they offer dual protection: they protect people from emissions that are harmful to health and also protect machines and equipment from premature wear and failure.
The most appropriate separator or filter design demands an understanding of the particulate composition, its intensity and the facilities. These systems frequently operate in a three-shift operation and need to deliver a consistently high level of cleaning, for which there are a range of different approaches.
Conventional systems run constantly without taking into account the current load situation. This results in an extremely high energy consumption and no awareness of the system conditions. Reducing energy usage is vital, especially with regard to DIN EN ISO 50001 (Energy Management). For this reason, modern cleaning systems are equipped with the relevant sensor technology, intelligent process control and performance-related ventilation control, which not only maintains the optimal filter quality, it also reduces the energy costs to a minimum.
Monitoring the filter and volume flow is one of the fundamental system tasks.
The 81.600G differential pressure transmitter, developed specifically for customers, is perfectly suited to this task. Thanks to its compact design and versatile installation options it can be integrated seamlessly in new systems and retrofitted without any problem in existing systems. It is available in a variety of unidirectional or bidirectional measurement ranges and gives a standardised output signal that is easily processed by a PLC/DDC.
In all aspects, the 81.600G therefore contributes significantly to system efficiency and to improving the climate.
