4000GPD RO System (Rotek) – 500 LPH HD Complete With Membranes
R48,500.00
This *ROTEK Industrial Reverse Osmosis System is built for reliable high-output purification. Producing up to 4 000 GPD (≈ 500 LPH), it’s ideal for commercial bottling plants, water refill shops, industrial purification, or high-demand RO installations. Featuring 2 × 4040 high‑flow membranes, stainless steel housing, and a programmable micro-computer controller with real-time TDS monitoring, this unit combines performance with ease of operation. The automatic pulse-flush design helps minimize scaling and prolong membrane life while offering high recovery rates.
