Understanding the Benefits and Principles of Dry Chemical System

August 2, 2023

Fires in commercial kitchens can quickly escalate, costing thousands in damage and shutting down operations until the area has been properly cleaned up. Control Fire Systems Ltd provides cutting-edge fire suppression technologies to prevent this from happening.

Dry chemical systems employ dry powder stored in pressurized tanks that are then disbursed through an electrical or manual activation to smother and extinguish fire hazards.

Sodium Bicarbonate

Sodium bicarbonate, more commonly known by its brand name, baking soda, is a white crystalline powder used to clean teeth of stains as well as an ingredient in some antacid medications. According to FDA standards, it is generally recognized as safe.

Sprinkle it onto a fire, and it reacts chemically with its flame, producing carbon dioxide gas and water, delaying combustion reactions and cooling it down quickly. Furthermore, it serves as an effective suffocating agent and forms a key part of dry chemical fire extinguishers.

Sodium bicarbonate is one of the best agents to use on Class A fires, as its cleanup is far easier than with water damage.

Monoammonium Phosphate

Monoammonium phosphate, more commonly referred to by its acronym MAP, is an essential fertilizer that supplies plants with nitrogen and phosphorus they require for healthy growth. As an inorganic chemical fertilizer free from sodium and chloride content, monoammonium phosphate is often applied on calcareous soils in order to increase soil-phosphorus availability.

Phosphoglycerine (PGH) fertilizers provide plants with essential nutrients and are highly water-soluble, with more Phosphorus concentration than many other phosphate sources, and are generally applied as granular fertilizers.

Dry chemical systems offer an ideal alternative to sprinkler systems in environments that demand minimal damage to equipment and materials, such as computer vaults, artwork, or retail cooking operations. Furthermore, dry chemical systems may be preferred over sprinkler systems in light manufacturing facilities where water could hinder operations resulting in costly downtime, such as paint booths. Furthermore, this system may be beneficial in hazardous areas where liquid may pose risk, such as battery rooms or chemical storage spaces.

Potassium Chloride

Potassium chloride is a salt chemical element produced through mining potash and refined using fractional crystallization or flotation processes. Produced as white to colorless face-centered cubic crystals, potassium chloride plays an essential role in cell function, muscle formation, and heartbeat regulation, also helping lower blood pressure by decreasing sodium intake. A diet rich in potassium also has blood pressure-reducing benefits.

Dry chemical fire suppression systems utilize powdered compounds to smother and extinguish fires. When activated either electrically or mechanically, a valve opens, releasing powder into piping systems and nozzles for use against fires.

These chemicals are ideal for industrial environments like chemical storage, petrochemical loading and unloading facilities, paint systems, or paint booths where a fire could break out quickly and efficiently, providing fast response time and mitigating significant damage or downtime until help arrives. More cost-effective than installing fire sprinklers in such spaces without necessitating draining of water or extensive cleanup after the event has transpired.

Foam Compatible

Foam compatibility refers to the ability for one foam concentrate of its type and proportioning rate to be mixed with another of similar type and proportioning rate, without altering chemical, physical, or performance characteristics. Fire departments should know that all modern AR-AFFF concentrates are foam compatible.

Dry chemical systems use AFFF concentrates mixed with salt or freshwater as an extinguishing solution on fuel surfaces to form an expanded foam blanket that smothers any potential flames from spreading further.

Dry chemical systems are an easy, cost-effective solution for protecting flammable liquid storage areas, petrochemical loading/offloading facilities, auto paint booths and dip tanks, and other industrial applications where a sprinkler system may not be appropriate. When activated either electronically or manually, they release dry powder that rapidly extinguishes fires before an electrical reactivation process restores power to equipment and structures after extinguishment has taken place. Control Fire System LTD offers foam-compatible dry chemical fire suppression solutions designed to protect property, personnel, and other assets in the most hazardous working environments.
