Services/Products
ISK offers a range of fire protection solutions. Below is a summary of each service/product:
Sprinkler Systems
- Description: Effective and reliable fire protection for industrial, commercial, and residential applications. Recognized by authorities and insurance companies for asset and life protection.
- Features:
- Long-term solution (30-50 years operational life).
- Uses 1ალ – 1/100th the water of fire brigade response, reducing water damage.
- Activates at fire outbreak to prevent spread.
- How It Works:
- Pressurized water in pipework.
- Sprinkler head with glass bulb/solder fuse breaks at 68°C, releasing water onto a diffuser.
- Flow switch activates pump and fire alarm.
- Types:
- Wet Sprinkler Systems: Water-filled, immediate response.
- Alternate Sprinkler Systems: Drained and air-pressurized in winter, water-pressurized in summer for temperature-extreme environments (e.g., unheated warehouses).
- Maintenance Requirements (Commercial):
- Valve sets: 6-monthly servicing (overhaul + visual inspection).
- Pumps: 6-monthly servicing (overhaul + visual inspection).
- Tanks: Annual ball valve service, re-lined every 10 years.
Suppression Systems
- Carbon Dioxide (CO₂)
- Overview: Extinguishes fire by reducing oxygen levels and cooling. Stored as liquid under high pressure, vaporizes rapidly during discharge.
- Pros: Highly effective, zero ozone depletion, non-conductive, no cleanup required.
- Cons: Slow discharge, toxic at high concentrations, bulky storage.
- Benefits: Clean, low-cost, suitable for delicate machinery.
- HFC 227-EA (FM-200)
- Overview: Clean, electrically non-conductive agent that extinguishes fires within 10 seconds by absorbing heat.
- Pros: Rapid action, safe for occupied areas, zero ozone depletion.
- Cons: Some global warming potential, higher cost.
- Benefits: Rapid knockdown, minimal oxygen reduction, no residue.
- Novec 1230
- Overview: Stored as liquid, discharged as gas, extinguishes via heat absorption and chemical interference.
- Pros: Safe for occupied areas, fast action, environmentally friendly (zero ozone depletion, GWP of 1).
- Cons: High agent cost.
- Benefits: Safe, effective, clean, no over-pressurization vents needed.
- IG55 (Argonite)
- Overview: Blend of nitrogen and argon, environmentally neutral, safe for occupied areas.
- Pros: Zero ozone depletion, no residue, effective in confined spaces.
- Cons: Slow extinguishing, high storage volume.
- Benefits: Fast-acting, integrates with detection systems, minimal downtime.
