These systems are the most common and are used in areas which have conditioned air spaces above 40° F / 4.4° C. These type of systems employ automatic sprinklers attached to a piping system containing water and connected to a water supply so that water discharges immediately only from sprinklers opened by heat from a fire.
These systems are used in areas subject to potential freezing with temperatures less than 40°F / 4.4° C. These type of systems employ automatic sprinklers that are attached to a piping system containing air or nitrogen under pressure. The release of air from the opening of a sprinkler permits the water pressure to open the dry pipe valve, allowing the water to flow into the piping system and out the opened sprinklers.
These systems are used to protect areas where higher hazards are present. Deluge systems employ open sprinklers that are attached to a piping system that is connected to a water supply through a valve that is only opened by the operation of a detection system installed in the same areas as the sprinklers. When this valve opens, water flows into the piping system and discharges from all sprinklers attached thereto.
These systems are similar in nature to deluge type systems, except the sprinkler heads are closed type as in dry type systems. They employ automatic sprinklers that are attached to a piping system which contains air that might or might not be under pressure, along with a supplemental detection system installed in the same areas as the sprinklers. These types of systems are intended to give one a pre-notice that a fire, damage or discharge of the system is about to occur, prior to water entering said system.
These systems are highly sophisticated in nature and require a high level of understanding in order to be designed and installed properly. Basically foam water systems can be either pre-primed wet dry pipe, deluge, pre-action or spray type, depending on the hazard and application. A very specific type of foam concentrate is used which is injected thru a device that proportions the concentrate with the water supply thus creating a foam solution that is then discharged thru the applicable outlet being used.
Fire Pump Systems are utilized, in conjunction with any type of Fire Sprinkler System, where the available water pressure is inadequate and must be boosted to the required water demand or when a pressurized water supply fails. They may also be utilized when an onsite water supply, from a storage reservoir, is required where no pressurized water supply is present. Fire pumps are typically horizontal split case or vertical turbine type driven by either an Electric Motor, Diesel Engine or Steam Turbine. We have, on staff, a Master Fire Pump Technician with extensive Factory Training and over 30 years of field experience to assist you with any fire pump needs you may have.
