Food Processing — FAQs
Are these products safe to use around food?
CRT products are formulated for use in building drains and HVAC systems and are not intended for food‑contact surfaces. Follow your facility SOPs/HACCP plans and always consult product labels and SDS.
Do you provide documentation for audits?
Yes. We provide SDS, spec sheets, and product labels. We can also help standardize SKUs and PM schedules across areas to simplify audits.
How often should drains and coils be treated?
Most plants operate on 30–90 day drain cycles and periodic coil maintenance based on load and environment. We’ll help set a schedule that fits your facility.
