The DHT SP Series advanced plate-type boiler water fired water heater incorporates the company’s field-proven PID controller with high-efficiency plate and frame or brazed plate heat exchangers to satisfy potable water heating needs in commercial and institutional environments. The packaged systems utilize simple, real-time load tracking and responsive controls to maintain accurate hot water temperature under various load patterns.
SP Series indirect water heater can efficiently produce up to 150 GPM of 140° F domestic hot water. Units can be coupled with all major medium-, normal-, and low-temperature condensing boiler water to achieve high efficiency in an optimal space. The control system features a durable RTD temperature sensor transmitting a 4-20 MA signal through quality twisted shielded wiring. The signal transmits directly into the PID controller, which in turn sends a signal to the electrically activated two- or three-way control valve to achieve accurate temperature control over various demand situations.
Maintenance is easy with the SP water heater. Flanged vitualic or union connections allow for the complete removal of the heat exchangers without disturbing the water heating piping. Isolation valves, inlet strainer and backflush connections are provided for scheduled maintenance.
