New AirQuality Sensor Provides a Wi-Fi Based Connectivity

Press Release Summary:

The AirQuality Sensor is designed for monitoring the concentration of particles on the shop floor at 12 ft height. It can detect concentration of particles between 0 and 28 µg/cft, for particles from 0,1 µm und 100 µm. The unit is suitable for Airtowers ranging from 3,000 to 11,800 cfm and works within a range of 14° F to 122° F. It sends data to intelligent over-drive control of the Airtower.

All-New AirQuality Sensor Optimizes Overall Efficiency in Welding Fume Extraction

Automated control for the ULT Airtower based on particle concentration

ULT LLC recently introduced the all-new AirQuality Sensor. The sensor is constantly monitoring the concentration of particles on the shop floor at 12’ height, adjusting power of the ULT Airtower according to the workload.

The all-new, light-based sensor detects concentration of particles between 0 und 28 µg/cft, for particles from 0,1 µm und 100 µm. A special visible gauge displays the contamination from green to red for reference purposes.

With a concentration of higher than 5%, the Airtower will power up automatically. When the concentration is below 5% for more than 20% the Airtower automatically enters in to stand-by-mode, saving on power consumption. 

The hard-wired AirQuality Sensor provides data to the intelligent over-drive control of the Airtower, adjusting power as needed. A WiFi based connection is available on request.

The particle sensor within the AirQuality Sensor unit is easily replaceable, guaranteeing durability of the entire set-up and reducing costs for maintenance.

The all-new AirQuality Sensor is supporting all variants of the ULT Airtower, from 3,000 to 11,800 cfm. The sensor works within a range from 14° Fahrenheit to 122° Fahrenheit.

With less than 75 dB(A)m the ULT Airtower is one of the most noiseless units in the market. The system utilizes the layer ventilation principle, named the best way of air circulation for welding shop floors. Furthermore, no ducts, nor expensive installations are required.
