Koch-Chemie PreFoam efficient — Highly Concentrated Alkaline TFR Pre-Cleaner, 20 L

Koch-Chemie PreFoam efficient: High-Concentrate Alkaline TFR Pre-Cleaner

Koch-Chemie PreFoam efficient is a highly concentrated, phosphate-free and NTA-free alkaline foaming Traffic Film Remover (TFR) with a pH of 13.5. Formulated for automatic rollover gantry washes, self-service wash arches, and heavy-duty pre-spray systems, it combines rapid dirt penetration with dense foam generation to strip stubborn road film, soot, bug splatter, and oily contamination.

1. Intended Purpose & Problem Solving

• Target Facilities: Rollover portals, tunnel systems, high-pressure foam arches, and self-service wash bays.
• Contaminants Removed: Oily traffic film (TFR), exhaust particulates, bug proteins, and atmospheric pollution.
• VDA Compliance: VDA Class B compliant.

2. Key Features & Technical Advantages

• High Dilution Efficiency: Extremely economical dosage rates lower cost-per-wash significantly.
• Dense Foam Cling: Combines chemical degreasing power with visual foam show and extended surface contact.
• Environmentally Sound: Phosphate-free and rapidly biodegradable in oil/water separators.

3. Application Guidelines & Dilution Ratios

• Foam Arch / Foam Lance: Dilute 1:20 to 1:50 with water.
• Dosing Pump Portal: Undiluted to 1:10 via injector pump (approx. 8–15 ml per car).
• Pre-Sprayer: 1:30 to 1:60.
• Protocol: Apply evenly -> Dwell for 1 minute -> Rinse with high pressure.

4. Critical Caveats & Safety Instructions

• Material Warnings: Do not apply on hot surfaces or raw aluminum. Do not let dry.
