The Liquid-Cooled Induction Heating System is designed for preheating, hydrogen bake-out and stress relieving applications up to 1450° F (788° C). The system can be operated in the Manual Programming mode where a power output is applied to a part for a specified time or in the Temperature Based Programming mode where part temperature is used to control power output. Liquid-cooled heating cables provide a highly versatile tool for preheating a variety of pipe diameters and even flat plate. In general, shorter cables are used for smaller diameter pipe and are easier to handle and set-up. Longer cables are used for larger diameter pipe or small pressure vessels and tanks. Great for preheat applications on geometrics that prevent use of air-cooled blankets.
Typical Applications for Liquid-Cooled Induction Heating Systems
Pipe Fabrication Shops
•Provides uniform heating around the circumference of higher strength pipe.
•Reduces set-up time and time-to-temperature in preheat applications.
•Significantly reduces consumable costs.
•Eliminates propane costs.
Field Construction of Power and Process Piping
•Provides uniform heating around the circumference of higher strength pipe.
•Provides rapid time-to-temperature, reducing total weld cycle time.
•Easy to set-up and operate in preheat applications - welder friendly.
•Reduces consumable costs.
Shrink Fit

Shipbuilding - Prop Shafts, Piping Systems, Plate (High Duty Cycle/High Temp)
•Provides uniform rapid heating in plate and pipe applications.
•Adaptable to heavy plate applications.
•Provides a safer, friendlier work environment for welders and operators. Personnel are not exposed to open flame, explosive gases or hot heating elements.
•Power efficient compared to resistance heating.
Mining
•Provides uniform heating on high hardness material to prevent cracking.
•More flexible than air-cooled systems for complex shapes.
•Enables higher preheat temperatures than air-cooled systems.
•Eliminates propane costs.

ProHeat™ 35 Induction Power Source
Built-In Temperature Controller
The ProHeat 35 Induction Power Source is equipped with a built-in temperature controller. The controller provides for Manual Programming or Temperature Based Programming. Manual programming provides for setting a power
level and a time duration. This is beneficial in preheat applications where a part is heated to temperature and the heating device removed. Temperature Based Programming provides the ability to develop procedures for preheat, hydrogen bake-out or stress relieve. Four control thermocouple inputs and two monitoring thermocouple inputs are provided
for heating. The control thermocouples are read by the controller which regulate the heat rise based on the hottest thermocouple and cooling based on the coolest thermocouple. This capability helps to insure the heating and cooling rates are not violated during the procedure. The controller is designed to be easily understood and programmed.
On-Board Diagnostics
The ProHeat 35 Induction Power Source is designed with on-board diagnostics with operator tutoring. Operating parameters are available at the touch of a button. Induction parameters are highly dependent on how the heating system (blanket or cable) is placed on the part to be heated. The ProHeat provides for Limit Conditions where a parameter maximum has occurred. The ProHeat will continue to deliver power, notify the operator and then provide helpful information to increase the output. The ProHeat will also identify Fault Conditions and provide information. The purpose of these capabilities is to provide continuing education of the operator on the use of induction heating equipment and protect the system.
