Tyco Water Spray Nozzles and Foam-Water Sprinklers in Bhopal

Fire Protection System (FPS) supplies Tyco nozzles for water spray fixed systems in Bhopal: Protectospray and MV medium velocity nozzles, Mulsifyre and HV high velocity nozzles, tank, cooling tower and tunnel nozzles, window exposure sprinklers and the B-1 foam-water sprinkler.

Where to use Water Spray and Foam-Water Nozzles

  • Oil filled transformers and switching equipment
  • Flammable liquid and gas storage tanks and spherical vessels
  • Chemical process equipment
  • Conveyor systems
  • Openings in fire walls
  • Diesel engines, turbo alternators, lube oil systems and oil fired boilers
  • Crossflow cooling towers with combustible fill
  • Tunnel deluge systems
  • Building windows exposed to fire from outside
  • Foam-water deluge systems

How to choose

A water spray nozzle is a fixed nozzle in a water spray system. Most of the Tyco nozzles here are open (non-automatic), so all of them discharge together when the system valve opens; the EA-1 is the automatic exception, opening by its own frangible bulb. Medium velocity nozzles (Protectospray EA-1, D3 and D4a, and the MV range) throw a filled cone of medium velocity droplets, mainly to cool the exposed surfaces of tanks, vessels and structures so they do not absorb too much heat from a nearby fire; at a high enough design density they can also control or extinguish fire. High velocity nozzles (Mulsifyre and HV) throw faster droplets and are aimed mainly at putting out oil and flammable liquid fires, for example on transformers.

Then match orifice, spray angle and material. Each data sheet offers a range of orifice sizes and spray angles. MV nozzles come in stainless steel, brass with leaded gunmetal LG2, titanium or 254 SMO, and the smaller sizes (MV10 to MV30) have an orifice insert and strainer. HV nozzles have an integral strainer and come in brass or stainless steel, and the D4a has a four arm body that helps protect it from knocks. For tanks, the MV-R reverse action nozzle covers spherical vessels and bulk tanks from any angle, and the MV-T covers tank tops.

Special hazards have their own nozzles. Type 1 and 2 cooling tower nozzles suit crossflow towers with and without diffusion decks. TN-25 and TN-17 horizontal spray nozzles let a single pipe run the length of a tunnel deluge system. Issue A and B window sprinklers wet window glazing against outside exposure fires, and the B-1 foam-water sprinkler draws in air to discharge foam in foam-water deluge systems. FPS supplies, installs and maintains Tyco nozzles in Bhopal and across Madhya Pradesh.

Frequently asked questions

What is the difference between medium velocity and high velocity spray nozzles?
Medium velocity nozzles throw a filled cone of slower droplets, mainly to cool exposed surfaces, though at higher densities they can also control or extinguish fire. High velocity nozzles such as the Tyco Mulsifyre and HV produce faster droplets aimed at extinguishing oil and flammable liquid fires, for example on transformers.
What is an open spray nozzle?
An open (non-automatic) nozzle has no heat sensitive element, so every nozzle on the system discharges when the system valve opens. Among the Tyco nozzles here, only the EA-1 is automatic, opening by its own frangible bulb.
What is a foam-water sprinkler?
It is an air aspirating outlet that discharges foam in a foam-water deluge system. The Tyco Model B-1 comes in upright and pendent versions with a K-factor of 3.0, and Tyco lists it as UL and ULC Listed.
How are open nozzles kept free of insects and dirt?
Tyco makes blow-off plugs (TFP890) for open Protectospray nozzles and open sprinklers, and the Mulsifyre range is offered with a Model F880 dust cap. Smaller MV nozzles and all HV nozzles also have built-in strainers.
Does FPS supply and install Tyco water spray nozzles?
Yes. FPS supplies, installs and maintains Tyco sprinkler system valves and nozzles in Bhopal and across Madhya Pradesh. Prices are on request: call or WhatsApp +91 92440 89060.
