JOWA F-2
Filtr remineralizujący do wody odsolonej
The JOWA F-2 re-hardening filter removes solid particles from evaporator water and raises its pH to 7.0–8.5 to limit corrosion of pipes, heat exchangers and tanks. A stainless steel (AISI 316L) vessel is filled with filter sand and pH-adjusting material between top and bottom strainers; two three-way valves switch between service and back-flushing. The manual covers installation between evaporator and fresh water tanks, filling, start-up, back-flushing, shut-off, safety, spare parts for all sizes and the type approval.
