Fire sprinklers can be open orifice or automatic. Automatic sprinklers are activated by heat that breaks the sensing device keeping the sprinkler closed. The water from the pipe comes through the sprinkler and hits the deflector and gives a water spray.
Fire Water Supplies
The water supply to the fire pump in fire sprinkler installations must fulfill the requirements for flow, pressure and duration. Sources can be public water mains, water storage tanks and inexhaustible sources like lakes, rivers and canals
A viable alternative to conventional radiator style heating systems is under floor heating. A typical solution consists of small bore pipes, laid in the concrete slab under the floor’s surface. The solution is typically fed by a condensing boiler or district heating.
The flow temperature refers to the temperature of the water in the supply (flow) pipe in a heating system or separate part of a heating system. If a heating system is directly connected to the district heating system its flow temperature is set by the district heating provider.
Foam sprinkler systems
Foam sprinkler systems use foam to extinguish fires in buildings. The fire sprinkler pump distributes the water & foam mixture via the pipe-system and discharges the foam spray via the sprinklers.
Free release fire pump
Free release fire pumps are standard pumps used as fire pumps. These standard pumps are not made for fire pump application, which can cause poor functionality in a sprinkler-pump application due to risk of clogging and instabilities in System pressure.
