Commercial RO Plant | 3000 LPD

A commercial reverse osmosis system producing 3000 LPD (800 GPD) of permeate — same core RO configuration as the 3000 LPD with pressure tank model but supplied without the permeate pressure tank. Suits commercial installations where the operator wants to size the storage tank to their specific demand profile, or who already has a suitable pressure tank in service.

Why Choose 'Without Pressure Tank'

The pressure tank for an 800 GPD commercial RO is typically a 50-100L vessel. Pre-sized bundles are convenient but not always optimal:

• High-demand sites may benefit from a larger 100L+ tank than the bundled package provides
• Light-demand sites may want a smaller 20-50L tank to save space
• Existing installations upgrading the RO membrane and pump may already have a serviceable tank
• Custom commercial builds may specify a particular tank brand or format for compliance, branding, or maintenance reasons

For those scenarios, this model gives you the RO assembly without the tank decision pre-made.

What 3000 LPD Production Delivers

Mid-to-large commercial drinking-water installations:

• Mid-size restaurants and full-service cafés
• Multi-chair dental practices
• Educational facility kitchens and labs
• 30-50-bed aged-care drinking water
• Small commercial food preparation
• Light-industrial process water at moderate volumes

For higher demand, step up to the 500 LPH stainless industrial system. For lower demand, the 1500 LPD/400 GPD system may be the better fit.

• Compression brine: 1/2"
• Dimensions: H 77 × W 42 × D 26 cm
• Controls: automatic flushing, high-pressure switch, low-pressure switch, provisions for pressure tank

Sizing the Pressure Tank Separately

For 800 GPD output, recommended pressure tank capacity is 50-100L depending on demand profile:

• 50L tank: intermittent demand, single-outlet draws of 5-10L at a time
• 100L tank: peak-hour concurrent demand from multiple outlets, busy commercial environments

Matching Bestank-Solar tanks: 50L and 100L are the typical choices.

Pre-Sale Water Analysis

For commercial RO installations, we strongly recommend providing a water analysis report for the intended site. Inlet TDS, hardness, chlorine, and ion-specific data drive pre-treatment selection, membrane life expectancy, and reject ratio. Contact our team for site-specific sizing recommendations.
