Polyurethane Chemicals Emission Control
We make complete line of products serving polyurethane industries around the world.
Ductless Hoods & Fume Extractors Filter Change Indicator Stickers.
Air Quality Monitoring.
Drum Type Filter Change Indicators.
These filter change indicators include the BTI, BTI Inline , BTI AFT (suitable for high toxic materials such as hydrazine and aromatic diisocyanates).
Leak Detectors.
Chemical Transport trucks and Chemical Storage cabinets.
DG Filters with end of service life indicators.
DG Filters are suitable for chemical reactions vents. Because of the special blend media, it have high capacity to trap gases and vapors. Easy to refill consumed media. Are ideal for chemical processes vents. And are convenient to use. Filters have end of service life indicators (ESLI). It allows user to safely use filter without the exposure to toxic vapors. In addition, It protects from filter breakthrough of toxins to the surrounding area. The ESLI changes color when the filter is about 75% to 80% consumed, allowing 20 to 25% of sorption media as a safety buffer.
2500 Series has 3 lb. of refillable media.
2600 Series has 5 lb. of refillable media
2700 Series has 10 lb. of refillable media.
Wiped to Detect and Measure Toxic Materials on surfaces.
Colorimetric surface wipe provide real time indication of the presence of trace amounts of aromatic diisocyanates on surfaces. The unique design of the wipe provides uniform color change enabling user to measure aromatic diisocyanates contamination using the color comparator.
The ChemWipe detects monomers and oligomers.
Validation report available.
