When it comes to safeguarding industrial assets, commercial warehouses, or high-density residential developments, the reliability of your fire suppression system is only as good as its water source. In South Africa, the term ASIB Approved Tanks represents more than just a regulatory checkbox—it is a guarantee of performance, insurance compliance, and structural integrity under the most extreme conditions.
At Rainbow Reservoirs, we specialize in the design, manufacture, and installation of premium, ASIB-listed steel fire protection tanks engineered to meet the stringent requirements of the 12th Edition Rules.
Why ASIB Approval is Non-Negotiable
The Automatic Sprinkler Inspection Bureau (ASIB) is the leading authority for fire protection standards in South Africa. Since 1970, ASIB has set the benchmark for sprinkler system reliability. Their statistics speak for themselves: there has been no recorded total loss of a building under normal fire conditions where a valid ASIB Clearance Certificate was in place.
Installing an ASIB-approved tank ensures:
- Insurance Validity: Most South African insurers mandate ASIB compliance. Without it, you risk higher premiums or the total rejection of claims following a fire incident.
- Calculated Performance: These tanks are designed to provide the specific flow rates and durations required by law, ensuring your pumps never run dry when they are needed most.
- Legal Compliance: Meets the safety standards required by the Occupational Health and Safety (OHS) Act and SANS 10400-T regulations.
Engineering Excellence: The Rainbow Reservoirs Advantage
Our fire protection tanks are not “off-the-shelf” water storage units. They are specialized reservoirs built with advanced materials and dedicated fire-safety features.
1. Superior Aluzinc Construction
We utilize high-tensile steel coated with a specialized Aluminum-Zinc alloy (Aluzinc). This material is specifically chosen for South Africa’s harsh climates, offering corrosion resistance that lasts significantly longer than traditional galvanized steel.
- Note: Our tanks are manufactured using high-grade Aluzinc for maximum durability and structural lifespan.
2. Customised Vortex Inhibitors
A critical requirement for ASIB compliance, our customized vortex inhibitors prevent air from being sucked into the pump system during high-volume discharge. This ensures a steady, high-pressure flow of water to your sprinklers and hydrants, preventing pump cavitation and system failure.
3. Heavy-Duty Bladder Liners
We use 1000gsm, reinforced PVC (RPVC) liners. This “tank-within-a-tank” design ensures that water never comes into contact with the steel walls, eliminating internal rust and providing a 100% leak-proof seal.
4. Modular, Rapid Installation
Our bolted-steel design allows for “flat-pack” delivery to any location. This modular approach facilitates:
- Quick Commissioning: Rapid on-site assembly by our expert teams.
- Flexible Footprints: We can configure volumes from 9,000 to over 4 million liters to suit your specific site constraints.
Standard Features for Maximum Reliability
Every Rainbow Reservoirs fire tank comes equipped with integrated components designed for immediate response:
- Water Level Indicators: For at-a-glance monitoring of your fire reserve.
- Safety Ladders & Large Manholes: Handrails for safe inspection access.
- Aesthetic Integration: Tanks can be color-matched to your existing infrastructure or corporate branding.
