Water Heater (Requied by NFPA)

To make sure engine start up very fast at any working environment, have to make sure the coolant water keep at a reasonable temperature, its required to maintain water temperature at 49 degrees (+-5 degrees), So we have to add the A7: Water Heater Device: to keep the water temperature at required level.

As part of SinoMac, PumpMac provides abundant premium pump-driven power pack options, WPT PTO, Advance gearbox and pump head, as well as customized water pump set.

The operational workflow of the fire pump anti-freeze heater (Water Heater Device) in the NFPA 20 Standard

Temperature Monitoring Phase

Sensor Deployment: Temperature sensors are installed on the pump body, pipelines, or water storage areas to monitor water temperature in real time.

Heating Trigger Phase

Control Logic: The temperature sensor transmits signals to the controller, which activates the heating element after verifying the temperature is below the threshold.

Constant Temperature Insulation Phase

To make sure engine start up very fast at any working environment, have to make sure the coolant water keep at a reasonable temperature, its required to maintain water temperature at 49 degrees (±5 degrees).

Safety Protection Phase

Overheating Protection: When the temperature exceeds 49 degrees (j±5 degrees), the heating power supply is forcibly cut off to prevent equipment damage.

Alarm Feedback Phase

Temperature Abnormality: Triggers audible and visual alarms when the temperature continuously falls below the anti-freezing threshold or exceeds the safety upper limit.
