RO 132 Reverse Osmosis Tank for RO Equipment Manufacturers and Distributors
The RO 132 Reverse Osmosis Tank is a 12 litres (3.2 gal) metal storage tank for reverse osmosis systems. It holds purified water under pressure, ready for the unit. We manufacture it at our own plant in Gebze, Türkiye. We also supply it wholesale to water treatment equipment manufacturers, assemblers and distributors.

This size suits under-sink and office units that need more storage. It uses the same 1/4" NPT connection as the RO 122. As a result, you can offer it as a capacity option on the same unit platform.
