Accuheat PFA Inline Heater Introduction 1–1 INTRODUCTION This section describes the IMTEC Accuheat PFA series of In-Line Heaters. This section includes the following information: • Overview of the basic models • Components Overview • Specifications • Facilities Requirements Overview – Basic Model The Accuheat PFA is an efficient in-line heater combining low cost- of-ownership with an extended service life.
Page 16: Power Modulators
The heater module can be interconnected with other Accuheat modules to provide an optimum configuration for temperature rise, fluid flow and three-phase electrical load balancing. A special version of the IMTEC Model 951 Controller is also available for process control. 1.1.2 Power Modulators The basic purpose of power modulators is to extend the life of the heater element.
Page 17: Theory Of Operation - Heat-Up Times
The heat-up time curves in the following figure, reflect the amount of time for 30 liters of DI water to raise to operating temperatures using an IMTEC PFA In-Line Heater. The results do not include heat loss from plumbing or other system components. A 6.0kw model was used to reflect these times.
