Food-grade sanitising equipment: what compliant actually looks like

A food-grade sanitiser applied through the wrong sprayer is not a compliant process. The tank, seals and wetted parts all touch the chemical before it touches your food-contact surface. If you run a commercial kitchen, catering operation or food plant, here is what to look for in the application gear itself.

Three things make application gear food-safe

• Materials fit for the job. For direct food contact work such as oils, additives and release agents, use certified equipment. The Klager CHEF is certified for direct food contact under EC 1935/2004, the European food-contact materials standard.
• Seals matched to the sanitiser. Chlorine and hypochlorite-based sanitisers want EPDM seals. Quat (quaternary ammonium) sanitisers vary by formulation, so send us the SDS and we will confirm the seal. An incompatible seal sheds particles and leaks, neither of which belongs near food.
• A dedicated unit per chemical. One sprayer for sanitiser, one for degreaser, clearly labelled. Cross-contamination between chemicals ruins both and confuses audits.

Spray or foam in a food facility?

Both, for different jobs. Spraying suits benches, small equipment and final sanitise passes. Foaming suits walls, production lines, coolroom surfaces and anywhere vertical, because the foam clings for its full contact time and shows you exactly what is covered. Most food plants run a foamer for cleandowns and a sanitising sprayer for touch-ups.

The daily-use test

Food businesses sanitise every day, sometimes every shift. Consumer spray bottles fail in weeks under that duty. A professional unit with the right seal runs for years, and when the seal finally wears, a genuine seal kit renews it. Cheaper per month, and no dead sprayer mid-shift.

A simple compliant setup

• Sanitiser: 1.0 to 1.5L EPDM-sealed mini sprayer for benches and equipment.
• Degreaser: foamer for canopies, walls and floors, EPDM if the degreaser is caustic.
• Direct food contact: Klager CHEF for oils and additives.
• Labels on everything, and the SDS folder up to date.

To mix a chlorine sanitiser to a set strength, such as 100 ppm, or to the rate on your sanitiser's label, use our Dilution Calculator. It gives the mL of concentrate and water for your sprayer size.

Frequently asked questions

Which seal for a chlorine-based sanitiser?

EPDM, or a model rated for bleach. EPDM is the manufacturer's rule for chlorine and bleach, rated up to 12.5% available chlorine. Chlorinated detergents have other ingredients, so send us the SDS. See the Chemical Compatibility Guide.

Do I need certified food-grade for sanitising floors and walls?

No. Certification matters for direct food contact. For surfaces, the priority is the right seal and a clean, dedicated unit.

Can you supply multi-site catering or processing groups?

Yes, through a trade account, including custom labelling so every site runs identical, clearly marked gear.

See the food processing and catering range, or request a quote and tell us your sanitiser. We will confirm the seal and the setup.
