Biocide · AD-402
Recirculating Cooling Water Non-Oxidizing Fungicide
Isothiazolinone-based non-oxidizing biocide for cooling towers and closed loops. Long-residual action; complements AD-401 in dual-biocide rotation programs.
Description
AD-402 is an isothiazolinone-based non-oxidizing biocide providing long-residual microbial control. Its dual-active formulation (CMIT/MIT) delivers rapid kill followed by sustained inhibition of bacterial regrowth. Used in alternation with AD-401 and oxidizing biocides to prevent the development of biocide resistance in long-running cooling systems.
Typical Applications
- Recirculating cooling systems
- Closed-loop chilled water
- Industrial wet scrubbers
- Pulp and paper process water
Other chemistries in the range
Complementary products worth specifying together.
Most industrial water programmes use 3–5 chemistries in concert — a coagulant, an antiscalant, a biocide rotation, and a corrosion inhibitor. Here are three from our catalogue that pair commonly with this product.
