Frequently Asked Questions About RAS

Is RAS suitable for areas with limited water resources?

Yes. RAS recycles over 90% of water through multi-stage filtration, making it ideal for drought-prone or inland regions where water supply is scarce.

Can I grow both freshwater and seawater species using your system?

Absolutely. Our systems are modular and can be configured for freshwater, brackish, or full seawater applications—just specify the target species and salinity range during consultation.

How do you control ammonia and nitrate buildup in high-density tanks?

We integrate multi-stage biofiltration (fluidized beds + trickle bio-towers) with real-time sensor feedback, ensuring efficient nitrification/denitrification. This keeps NH₃ and NO₂⁻ levels consistently below critical thresholds.

What makes your protein skimmer more effective than basic foam separators?

Unlike basic skimmers, ours use high-efficiency venturi injectors + micro-bubble contact chambers to remove fine dissolved organic matter (DOM) and improve water clarity.

I only need drum filters and oxygen cones—not the full system. Can I buy components separately?

Yes. Every module (filters, skimmers, UV, tanks, PLCs) is available à la carte. You can start small and expand gradually as needed.

How do you prevent fish stress in high-density setups?

We use intelligent DO/temp/pH control, round-edge tanks with laminar flow design, and optional shading/aeration zones. This minimizes territorial aggression, oxygen dips, and water turbulence.

What certifications do your products meet?

Our systems comply with:

  • ISO 9001

  • CE / RoHS / IP65 (for electrical components)

  • SGS inspection reports available for tanks and filters
    These meet EU, US, Middle East import requirements.

What's the average energy consumption of your RAS system?

A 50–100 m³ system consumes 0.3–0.5 kWh/m³/day under standard load. Nano-bubble oxygenation and peak-shift logic in PLCs reduce blower/pump runtime by up to 25%.

How fast can I expect ROI from a YUTANK RAS system?

Typical ROI is within 12–18 months for high-turnover species like tilapia or shrimp. Faster if you have vertical integration (processing/export). For specialty species, ROI depends on market premium.

Can your tanks handle seawater without corroding in 2 years?

Yes. Our PP tanks and galvanized steel tanks include EPDM liners, UV-resistant coatings, and 316L fittings for long-term marine use. No rust, no deformation.

Do I need skilled technicians to run the system?

Not necessarily. Our touch-screen PLCs offer pre-set programs, automatic alerts, and multi-language UIs. Local staff can be trained within 2–3 days with video guides + remote support.

How do you ensure backup during power outages?

We support auto-restart logic + external UPS/generator ports. Clients in blackout-prone regions often install DO fail-safe alarms + solar/inverter backups.

Will it work in high ambient temperature climates (40–45°C)?

es. We’ve deployed systems in Saudi Arabia and Vietnam with thermal insulation, water chillers, and closed-loop temperature control. You’ll get species-specific thermal guidance.

What species can be raised in your system?

From bass, eel, and trout to exotic species like sea cucumbers, king crabs, and even ornamental koi or zebrafish—our systems are adaptable to nearly any aquatic animal with predictable parameters.

Do you offer installation and after-sales support overseas?

Yes. We provide:

  • Pre-assembled modules

  • English manuals & CAD layouts

  • Remote video commissioning

  • On-site engineers for large-scale projects

  • Global spare-parts shipping via DHL/FedEx
