On-coil UV-C
Cognituv Grid
Cognituv Grid puts UV-C light to work on your cooling coils around the clock — so biofilm and mold don’t get the chance to build up, and your air handlers keep doing the job they were designed for.

We set your site up on Cognituv Connect: wireless sensors for energy, water use, indoor and outdoor air quality, equipment health and more, all in one dashboard. Within 30 to 60 days you have a baseline and a findings report showing where money, comfort or equipment life is slipping, and what’s worth fixing first. Whatever you fix, the same sensors measure the result.
Scoped and quoted for your site.

What’s costing you?
Start from the problem. We’ll bring the kit, the method, and the proof.
Treat the air at the coil, in the duct and in the room.
Cognituv Grid keeps coils clean, in-duct UV-C treats the moving airstream, and FreshFilter and Overwatch treat the rooms a central system can’t reach. IAQ monitors keep the results on the record.

18 months complaint-free at Northrop GrummanKeep coils clean, then measure what it saves.
Biofilm on cooling coils restricts airflow and heat transfer, so fans and cooling plant work harder. Cognituv Grid keeps the coil clean around the clock, and smart CTs on the major loads measure the result against a baseline agreed for your site.

UV-C treats water in the pipe run or in the tank, with no chemical additives. Inline sensors keep quality on the record and alert your team to excursions before they cost you.
