Proportional doser
Promax Dosierer, 4 l/min, Flaschenbefüllung

Promax doser, 4 l/min, bottling

Sturdy proportional doser (wall mounting) for filling 1 litre bottles and other spray bottles with glass cleaner, interior cleaner, etc. Depending on the presetting, the venturi principle enables a broad range of dilution ratios to be generated reliably and always consistently. Any number of Promaxes (for different products and/or mixing ratios) can be switched in series with just one water connection. This system prevents the material wastage that frequently occurs on premixing by hand, and is therefore extremely economical. With water pressure fluctuations/water hammers we recommend the installation of a pressure reducer. Suitable for acidic, neutral and alkaline products. Output: 4 litres/minute, mixing ratios: 1:4 - 1:150.

Dosatron D3 RE 10 AF

Dosatron D3 RE 10 AF

Proportional doser for producing ready-to-use precleaner solutions. Optimally suited for operating low-pressure lances (eg PVC 600 mm lance, 999419). Thanks to a patented mechanism (no Venturi principle) the same dilution is produced even with fluctuations in the water pressure. This system prevents the material wastage that frequently occurs with manual premixing and is therefore extremely economical. With water hammers (same water supply pipe with high-pressure appliances or carwash) we recommend the installation of a pressure reducer. Suitable for neutral and alkaline products. Dosing range: 1 – 10%. Operating pressure: 0.5 - 6 bar. Water throughflow: 10 l/h - 3000 l/h.

Dosatron D07 RE 5 AF

Proportional doser for producing ready-to-use precleaner solutions. Optimally suited for operating low-pressure lances (eg PVC 600 mm lance, 999419). See Dosatron D3 RE 10 AF for more details. Suitable for neutral and alkaline products. Dosing range: 0.8 – 5.5 %. Operating pressure: 0.3 - 6 bar. Water throughflow: 5 l/h - 700 l/h.
