Engine protection, also referred to as volume protection, refers to the design of systems to cover hazards within the volume of the engine compartment. This method of protecting machines means that hazards located outside the engine compartment are not protected. The system design is based on the volume of the protected area, and the amount of agent and number of nozzles required to protect this area.
On average, over 25% of fires in heavy mobile equipment originate outside of the engine compartment, so neglecting fire hazards outside the engine compartment puts you and your business at risk of fire. This is why Ardent recommends full hazard protection, which considers hazards outside of the engine compartment in addition to those within. These hazards can include the transmission, battery compartment, belly pan or high-pressure hoses and hydraulic pumps. The fire hazard identification process identifies the areas within the plant that pose a fire risk, and the system design is based on this.
