ENCLOSURES FEATURE
Keeping enclosure filters clean and critical equipment cool
Schneider Electric has launched the ClimaSys Smart Ventilation System, an intelligent filter and airflow management solution for multiple control panels or electrical distribution enclosures in new or retrofit applications
T
he system helps avoid equipment breakdowns, maintain uptime, and
improve energy efficiency by automatically alerting maintenance personnel when filters or other ventilation parts need servicing or replacement. “When ventilation system filters
become blocked with dust or dirt, enclosures can quickly overheat and cause equipment failures or fire,” says Josep Lopez, offer manager for Schneider Electric. “The ClimaSys Smart Ventilation
System monitors every aspect of ventilation performance, helping teams use predictive maintenance to keep equipment running safely and efficiently, while cutting filter-related costs by as much as 90 per cent.”
VENTILATION FAILURE Enclosures operating in harsh environments are particularly susceptible to filters becoming clogged, reducing internal airflow. When this happens, fans run inefficiently and consume more energy, while higher temperatures and accumulated dust can cause equipment failures and fire. This can result in expensive losses to productivity, short equipment lifespans, and higher energy costs.
The ClimaSys Smart Ventilation System
is a scalable, digital thermal network, designed to help facility teams stay connected to the ventilation status of every enclosure, anticipate and avoid shutdowns, and cut operational costs. A central FilterStat controller collects and
analyses information from filter and fan sensors across one or more enclosures. As part of each enclosure’s grille components, a smart filter with an integrated dust sensor uses patented infrared technology and advanced algorithms to determine the level of accumulated dirt. Sensors also measure the air temperature passing through inlet and outlet grille locations, enabling delta-T values for each enclosure. Smart fan components provide additional sensors to measure RPM, fan current, and temperature of the ‘transported’ air around each fan. This enables measurement of fan efficiency and whether internal temperature is exceeding fan capacity. Multi-colour LEDs on the front of each
smart fan and grille give clear indication of filter and fan status, while the central FilterStat controller displays information and alarms to help keep the ventilation system running efficiently. The controller can also connect to a PLC, speed drive, HMI, or other equipment.
BENEFITS The ClimaSys Smart Ventilation System provides a complete kit for greenfield applications. For existing installations, a retrofit kit option is designed to digitise any control or electrical panels in a simple, safe way. The system works with all possible
architectures, including being compatible with extractor or ventilation type fans. To support a large number of enclosures from a single Filterstat module, up to eight thermal hub devices can be used to extend network capacity up to 256 sensors. In every application, the system is
designed to reduce CAPEX and OPEX in a number of ways, foremost by minimising breakdowns and avoiding downtime. In addition, by keeping equipment cool, customers can also expect to increase equipment lifespan by up to two times. Energy efficiency will also be improved
by keeping fans running at maximum efficiency. Finally, staying informed on ventilation health means that filters will now only need to be replaced as and when required.
