The Diversified Heat Transfer (DHT) ST Series Semi-Instantaneous Water Heaters are the engineered solution for high recovery capacity in a small space. They are constructed with a stainless steel shell and other non-ferrous materials to ensure long leak-free operation. Designed for continuous high-peak loads, the DHT ST Series is ideal for high-demand applications, such as hospitals and dormitories.

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.

The DHT STP Series is a fully packaged storage water heater that utilizes a double wall brazed plate heat exchanger.
