Conventional air systems are breeding grounds for microbiological hazards like listeria, yeast, mold, legionella, sick building syndrome and more. When found in food products these hazards can result in sickness or, in some cases, death. Additionally, product recalls can also occur. We frequently hear about these in the news. The impact of these events for families and businesses can be devastating.

The transportation mechanism for these hazards is air. Traveling on dust and water droplets these hazards are the invisible danger that we address. For every food producer who struggles with air quality, every cheese and meat room, hydroponic growing room, mushroom and lettuce or high humidity area where products are washed and packaged, SDI understands the issues. The greatest comfort when food safety is on the line is knowing that proper safety and sanitary conditions exist.

SDI systems address the role of air quality in food plants. Air, the contact surface we never clean, is the invisible danger that puts life and business at risk. At SDI we have the motto, "BUILD TO A SPECIFICATION". We understand the risk associated with conventional air and SDI has the solution.

When writing the specification for your air system, the last item on the list is: "Make sure that it will do no harm"

  There is a paradigm shift in the air, and SDI is leading the change.
