The M Series is a very reliable water heater that incorporates a high quality centrifugal pump for recirculating hot water to the customer’s holding tank. This system is designed for applications where there is a need for a large quantity of water in a short time period. Using your vented water tank (not included), water is circulated by the pump through the heater and back into the tank, achieving the desired water temperature.
Standard construction features include: Indicator light to alert operator if low water flow limit switch has shut down burner due to inadequate water flow. The temperature control switch and the manual reset high temperature limit switch shut off burner in case of excessive water discharge temperature. ASME-rated pressure relief valve opens to discharge water in case of excessive pressure buildup. Pressure gauges and bi-metal thermometers on both inlet and outlet indicate incoming and outgoing water temperature and pressure. Y-strainer on water inlet ensures foreign particles do not enter heater water. Standard BTU ratings are 1,000,000-3,000,000. Standard primary electricals are 230V/3Ph/60Hz, 460V/3Ph/60Hz, 380V/3Ph/50Hz, 575V/3Ph/60Hz, and 230V/1Ph/60Hz. The entire system is mounted on a rugged steel skid.
