Industries We Serve
Forty years of NEBB-certified TAB across every demanding building type — from Joint Commission-regulated hospitals to precision-controlled data centers and research labs.
Our Expertise
Built for the Buildings That Can't Afford to Get It Wrong
HVAC TAB is straightforward in a simple office building. It gets harder — and the stakes get higher — in a hospital where wrong room pressure can spread infection, a lab where improper fume hood face velocity becomes a safety violation, or a data center where a cooling imbalance triggers a rack shutdown. dL Flow Tech has specialized in these demanding environments since 1982. Our NEBB certification, independent status, and 40-year track record are why engineers and facility managers on the most demanding projects specify us by name.

Independent TAB — No Conflicts, No Caveats
dL Flow Tech has never been affiliated with a mechanical contractor. That independence is not a marketing claim — it's the reason our reports carry weight with Joint Commission inspectors, NYSED reviewers, commissioning authorities, and engineers of record. When we certify a system meets its design, there's no installing contractor relationship to question. Since 1982, that's been the premise.
