What does ESFR mean?
What does an “ESFR” sprinkler system mean? ESFR is short for early suppression, fast response, which is exactly what you want out of your system should a fire break out. Primarily, ESFR sprinkler systems are used for facilities that have high storage piles, such as warehouses. Uniquely designed to fight fires by sending a high ]
What is the difference between ESFR and quick response sprinkler?
Speed - ESFR sprinkler heads sense a fire and begin spraying water quicker than standard response sprinkler heads. Volume - Conventional sprinkler heads output rate - 25 to 30 gallons per minute.
Are ESFR sprinklers wet or dry?
Early Suppression, Fast Response (ESFR) The Model ESFR-17 Dry Type Sprinklers are primarily used for ceiling only sprinkler protection and used to protect solid piled, palletized, and rack storage that is subject to freezing temperatures.
Can ESFR sprinklers be used in a dry system?

How do ESFR sprinklers work?
How do they work? ESFR sprinklers are designed to release 2-3 times the amount of water of conventional sprinkler heads and to emit larger droplets of water, which in turn have a greater momentum than droplets emitted from conventional heads.
What type of sprinkler system is recommended for cold storage?
It's recommended that you install a dry or pre-action fire sprinkler system in the cold space, and a water-based fire sprinkler system throughout the rest of the facility. This mix of two types of fire sprinkler systems ensures the best protection for both types of spaces.
What is the smallest K factor permitted for an ESFR sprinkler?
K-14.0Although ESFR sprinklers are allowed to be as small as K-11.2, the smallest actually available are K-14.0.
Can you insulate fire sprinkler pipe?
Blown-in insulation can be used to protect wet pipe sprinkler systems. However, care needs to be taken to ensure that the insulation does not get between the pipe and the warm space below.
What are the 4 types of sprinkler systems?
Types of sprinkler systems permissible by NFPA 13, Standard for the Installation of Sprinkler Systems, are wet, dry, preaction, and deluge.
What are the 2 types of sprinkler heads?
There are three basic sprinkler head types– Spray Irrigation Heads and Spray Rotary Sprinkler Heads, Bubbler Irrigation Heads, and Drip or Soaker Systems. Each different sprinkler head will water your plants in the particular way they like.
What are the two types of sprinkler systems?
Sprinkler system typesWet pipe systems. Wet pipe sprinkler systems are the most common system. ... Dry pipe systems. Dry pipe systems are installed in spaces where the ambient temperature may be cold enough to freeze the water in a wet pipe system, making a wet pipe system inoperable. ... Deluge systems. ... Pre-action systems.
What are the types of sprinklers?
What are the Different Types of Fire Sprinkler Systems? Wet pipe, dry pipe, pre-action, and deluge are four types of fire sprinkler systems. Each of these systems helps prevent flames from spreading and reduces fire damage.
What are the types of sprinkler irrigation?
There are four types of the sprinkler irrigation system as given below;Traditional Spray Systems.Drip Systems.Soaker Hoses.Rotor Systems.
What are the different types of sprinklers and how are they classified?
Sprinkler irrigation systems may be classified as portable, semi-portable, semi-permanent, or permanent. On the basis water application the sprinkler systems are classified into the following two major types: 1. Rotating head or revolving sprinkler system.
How many types of sprinkler bulbs are there?
4There are 4 common varieties of fire sprinkler heads: pendent, upright, sidewall & concealed - each with their own particular use.
What is an ESFR sprinkler?
ESFR sprinklers are the heavy hitters of the sprinkler world in three important ways: they are designed to activate quickly in order to achieve full suppression of a fire; they create large water droplets that resist evaporation on their way to the seat of a fire; and they release an immense amount of water to aid in suppression.
Can ESFR sprinklers be used in racks?
Depending on the storage scenario, ESFR sprinklers can eliminate the need for in-rack sprinklers. In Redlands, California—a reminder of the potential hazard posed by very large storage facilities packed with densely stored commodities. (AP/WIDE WORLD)
Features
Easy Installation – ESFR sprinkler systems are designed for easy installation and maintenance in warehouses or tank farm facilities where hazardous and/or combustible materials are stored.
Use include
Large storage facilities, such as warehouses, tank farms and distribution centers Steel industrial buildings with large open areas or high ceilings Process plants with a large number of tanks or vessels containing flammable liquids, ESFR sprinkler systems are used for a variety of applications including, but not limited to, supermarkets, restaurants, hospitals, computer rooms, shopping centers and storage facilities for hazardous or combustible materials..
Suppression media
The suppression media is the fluid that is held in the pipes inside of the sprinkler system. This media can be water or air depending on the type of sprinkler system being used (for example, conventional water based or dry pipe). In ESFR systems, this media can also be inert gases such as nitrogen to suppress fires.
What is a conventional sprinkler system?
Conventional sprinkler systems are designed to control a fire and prewet the surrounding area until it can become extinguished by the fire department or trained fire brigade. The sprinkler heads are smaller than ESFR heads and are designed to discharge lower pressures and flows.
Can a suppression mode sprinkler fail?
However if suppression mode sprinklers are obstructed or are not designed properly they will fail to suppress a fire and the results can be devastating. Specific detail to sprinkler design and installation is most important.
What is an ESFR sprinkler system?
ESFR (Early Suppression Fast Response) sprinkler systems are designed to achieve fire suppression for a specific type of storage occupancy before the fire becomes fully developed. ESFR heads vary with K-factors of 11.2, 14.7, 17 and 25.2 with as well as pressures of 50 and 70 psi. In most cases ESFR systems have not been tested for non-storage occupancies.
What is the advantage of an ESFR system over a conventional sprinkler system?
The main advantage of an ESFR system over a Conventional sprinkler system is the possible elimination of the requirement for in-rack sprinklers in rack storage areas. However if suppression mode sprinklers are obstructed or are not designed properly they will fail to suppress a fire and the results can be devastating.
Can ESFR be tested for non storage?
In most cases ESFR systems have not been tested for non-storage occupancies. Conventional sprinkler systems are designed to control a fire and prewet the surrounding area until it can become extinguished by the fire department or trained fire brigade.
Warehouses and other storage facilities require unique fire sprinkler solutions
An office building might have a similar square footage to a warehouse, but the two could not be more different to a fire protection engineer. That’s because warehouses present difficult hazards and require specially designed fire sprinkler systems and sprinkler heads.
The unique challenge of warehouse fire protection
Warehouses can be dangerous places when it comes to fire. For example, in 2007, a fire broke out in a sofa showroom and warehouse facility, and nine firefighters were killed. That same year, a warehouse blaze in Warwickshire, England, killed three firefighters.
In-rack, CMDA, CMSA, and ESFR sprinklers meet the challenges of storage occupancies
A precise design approach is necessary to meet the challenges of these occupancies, an effort that includes using storage fire sprinklers.
The design requirements for storage sprinkler systems are complex
As mentioned, designing most commercial sprinkler systems relies on density/area curves that determine how much water flow and pressure is needed. Selecting a curve depends on the occupancy hazard of a building. But while CMDA storage sprinkler systems use density/area curves, CMSA and ESFR systems aren’t based on this concept.
Storage fire sprinklers are specially designed to protect challenging environments
Again, warehouses and other storage occupancies present unique problems to fire sprinkler designers and engineers. High ceilings, obstructive storage arrangements, and highly flammable, densely stacked materials add up to increased fire danger.
