Page 5: Product Overview
1.2 – Product Overview DynaFLO is a prefabricated product mounted on a skid that provides controlled heat exchange between a boiler loop and a DHW (domestic hot water) loop. Heat is extracted from the boiler loop and through a very compact and efficient stainless steel brazed plate heat exchanger is transferred to the cold domestic water supply. -

Page 20: Part 6 - Components
Part 6 – Components 6.1 – Electro-Hydraulic Actuator 6.1.1 – Operation The Electro Hydraulic Actuator mounted on DynaFLO requires a 24 VAC supply and a 4 to 20mA control signal to proportionally control the actuator position. The actuators mounted on DynaFLO have a 3/4-inch (20 mm) stroke. The actuator communicates with the control through a 4 to 20 mA control signal. -

Appendix A – Special Considerations for low volume boilers dedicated only to a DHW load The diagram below demonstrates a situations where there are no loads other than a DHW load to take the heat coming from the boiler (such as space heating or etc.). In such cases if the DHW load on DynaFLO is suddenly reduced, the actuator starts closing down and bypassing the heat exchanger. -
