Tyco ESFR and Storage Sprinklers in Bhopal

Fire Protection System (FPS) supplies Tyco ESFR sprinklers, control mode storage sprinklers and intermediate level (in-rack) sprinklers in Bhopal, for warehouses, cold stores and high-piled storage. FPS installs and maintains them across Madhya Pradesh.

Where to use ESFR and Storage Sprinklers

  • Warehouses with high-piled rack, palletized or solid piled storage
  • Stores of cartoned and uncartoned plastics, within the commodity limits of each data sheet
  • Some arrangements of rubber tyres, roll paper, aerosols and flammable liquids, as listed for each ESFR model
  • Cold stores and box-in-box refrigerated storage, with the dry-type ESFR-17 and ESFR-25
  • Retail stores with storage and display areas, with the EC-25
  • Racks that need in-rack (intermediate level) sprinklers
  • Below open gridded catwalks, with intermediate level sprinklers
  • Tall storage buildings, up to 55 ft ceilings with the ESFR-34
  • Storage protected by dry pipe or preaction systems, with the Ultra K34

Tyco ESFR and Storage Sprinklers models

How to choose

Storage sprinklers work in one of two ways. ESFR (early suppression, fast response) sprinklers are suppression mode: they are built to knock a storage fire down early, and Tyco notes they are primarily used for ceiling-only protection, so in-rack sprinklers can be left out for the listed materials and heights. Control mode sprinklers aim to control a fire and limit its spread rather than suppress it; CMDA (control mode density area) designs set a water density over an area, while CMSA (control mode specific application) sprinklers follow specific NFPA 13 criteria for high-piled storage.

For ESFR, the K-factor drives the pressure needed at the last sprinkler. Tyco offers K14.0 (ESFR-1, ESFR-14), K16.8 (ESFR-17), K22.4 (ESFR-22), K25.2 (ESFR-25) and K33.6 (ESFR-34). Tyco states the ESFR-17 works at lower end head pressures than K14.0 ESFR, and the ESFR-25 lower than both K14.0 and K16.8, which gives flexibility in pipe sizing and may reduce or remove the need for a fire pump. The ESFR-22 and ESFR-25 can protect specific materials without in-rack sprinklers up to 40 ft of storage under a 45 ft ceiling (NFPA) or 45 ft under 50 ft (FM), and the ESFR-34 up to 50 ft under 55 ft. Choose the upright ESFR-17 where pipes must run below the ceiling, and the dry-type ESFR-17 or ESFR-25 for freezers.

Large orifice control mode sprinklers suit storage that does not use ESFR. The K11.2 ELO-231, ELO-231B, ELO-231FRB, K11-231B and K11-231FRB were fire tested to replace K5.6 or K8.0 standard spray sprinklers over high-piled storage, and the K16.8 K17-231 to replace K8.0 or K11.2; Tyco notes they give higher flow at lower pressure. The Ultra K17 and LD (large drop) are for CMSA designs, the Ultra K34 for dry pipe or preaction systems over Class III commodities, and the EC-25 is an extended coverage CMDA sprinkler covering up to 196 sq ft. The TY7158 and TY7258 are specific use retrofit sprinklers, and the TY720 is the electronically operated sprinkler of Tyco's EAS-1 system.

Intermediate level sprinklers go inside the racks, with a shield that keeps water from higher sprinklers off their heat sensitive element; Tyco offers them in the TY-L, TY-B, TY-FRL and TY-FRB series, and the K11.2 lines become intermediate level versions with a guard and shield. Approvals differ by data sheet, so match them to your NFPA 13 or FM Global design. FPS supplies, installs and maintains Tyco storage sprinklers in Bhopal and across MP.

Frequently asked questions

What is an ESFR sprinkler?
ESFR stands for early suppression, fast response. It is a large K-factor, suppression mode sprinkler for high-piled storage, used mainly at the ceiling so that in-rack sprinklers can often be avoided for the materials and heights listed in its data sheet.
Can Tyco ESFR sprinklers remove the need for in-rack sprinklers?
For specific materials and heights, yes. Tyco lists the ESFR-22 and ESFR-25 for up to 40 ft of storage under a 45 ft ceiling to NFPA, or 45 ft under 50 ft to FM, and the ESFR-34 for 50 ft of storage under a 55 ft ceiling.
Which ESFR K-factor should I choose?
It depends on the storage height, commodity and available water pressure. Higher K-factors such as the ESFR-17, ESFR-22 and ESFR-25 work at lower end head pressures than K14.0 ESFR, which Tyco says can ease pipe sizing and may reduce or remove the need for a fire pump.
Can ESFR sprinklers be used in a cold store?
Yes, with the dry-type ESFR-17 or ESFR-25. Each is an ESFR sprinkler fixed to a drop that stays dry until it operates, so it can hang inside a box-in-box refrigerated store fed from a wet pipe system outside it, with insulating seals to limit condensation and ice.
What is an intermediate level sprinkler?
It is a sprinkler fitted inside a storage rack or below an open gridded catwalk, with a shield that keeps water from higher sprinklers off its heat sensitive element so it is not cooled before it can operate.
Does FPS supply and install Tyco ESFR sprinklers in Bhopal?
Yes. FPS supplies, installs and maintains Tyco ESFR and storage sprinklers in Bhopal and across Madhya Pradesh. Prices are on request: call or WhatsApp +91 92440 89060.
