ULT adds solutions for Additive Manufacturing gas purification and extraction
November 25, 2024
Air treatment equipment manufacturer ULT, headquartered in Löbau, Germany, has announced the addition of the ACD 400.1 Ex extraction solution for the removal of atmospheres containing flammable components, and the AMF 60, a modular, compact gas removal machine.
ACD 400.1 Ex
The ACD 400.1 Ex was developed for the extraction and filtration of dry, flammable and non-flammable gases and vapours in concentrations up to 20% of the lower explosion limits. The system is a modular, two-stage storage filter device, consisting of an M5 dust pre-filter and two adsorption filter modules (activated carbon). To prevent ignition of flammable gases and vapours in the filter, the activated carbon filter elements and subsequent components — such as the explosion-proof fan compliant with ATEX Ex II 2G T3 and the ATEX-compliant motor — are earthed and designed to be free of ignition sources.
The ACD 400.1 Ex is noted for its extremely quiet operation, low energy consumption, and flexibility regarding changing workplaces or types of emissions. The filter cassettes are electrically conductive with a potential equalization connection and offer a high safety standard for users when changing filters. A T3 blower is installed in the device, allowing gases of temperature classes T1-T3 to be extracted safely.
The extraction unit can be equipped with collection elements (extraction arms, hoses, pipes) in various sizes and types.
Due to the high degree of gas filtration, the cleaned gas can be fed back into the work area via the standard integrated recirculation mode. For applications involving carcinogenic, mutagenic or reproductively toxic gases, the devices can be equipped with an exhaust air nozzle for exhaust air operation.
AMF 60
The AMF 60 is a modular, compact and gas-tight extraction and filter system, suitable for all inert gases (e.g. nitrogen, argon, helium).
In addition to simplified operation and safe maintenance and service, the AMF 60 enables low process costs and long filter service lives. The mobile, flexible system is equipped with a HEPA-H14 and reportedly offers a filtration performance of >99.995%, allowing the cleaned air can be returned to the work area. The storage filters allow contamination-free handling of highly flammable and health-endangering process pollutants.
The gas purification system can be integrated as a slave with I/O system or used as a stand-alone solution with CULT control. This specially developed new control includes standard components such as a timer for setting the running times or data log functions and modular extensions like sensor monitoring of all process parameters or customisable post-filters.
The AMF 60 requires a footprint of only 450 x 640 mm. Due to its UL conformity and voltage range between 90-250 VAC, the device can be utilised globally without any special adjustments.
