Management of Odor Improvement
Angel Air Purification products break down and eliminate many of the odors and gases produced during the casting process. Each product is formulated to chemically convert odors and harmful gases into odorless by-products.
After prolonged exposure to the strong gases triethylamine (TEA) and dimethylethylamine (DMEA), workers may experience blurred peripheral vision ("tunnel vision"). The odor of these gases can permeate clothing and vehicles and remain long after the source of the gas has been approached. By using natural deodorizing products to neutralize the odors emitted during the metal casting process, the harmful effects of the gases can be eliminated and strong odors can be eliminated.
Use an effective deodorizer in your metal casting plant. This natural, non-toxic grade deodorizer has been used in many industries from food processing, composting, wastewater treatment and more.

Sulphurous odors
Sulfur dioxide (SO2) is a common gas found in metal casting equipment. Angel Odor Control products react with sulfur dioxide to form organic salts that remove the odor.
Air Quality
In the field, ANGEL Metalcasting Odor Removal products dramatically reduced sulfur-based odors to acceptable air quality. It was found to be so effective in contact testing that it reduced sulfur dioxide levels immediately after application (the level of effectiveness depends on the concentration of the odor, the type of equipment used, and the amount of natural deodorizer diffused.)
The smell of disappearing bubbles
Molten metal is poured into a foam mold, which burns off the foam and produces styrene gas. A natural deodorizer product is fed into the exhaust line using an atomization system to eliminate gas odors.
Dust and Odor Control in Foundries
Using ANGEL air purification products eliminates odors in the work area and effectively suppresses dust throughout the foundry.
Nonferrous casting plant
Triethylamine and other gases can be a serious problem in the core rooms and pouring areas of non-ferrous metal foundries. Odor problems in foundries of all sizes can be solved with natural metal casting odor removal products.
Brass Foundry
The pouring areas of brass foundries are the source of a large number of odors. Angel deodorizer products can be added to the exhaust stacks in those areas to maintain consistent air quality.
