Induction Fluid Pipeline heating system
HLQ Induction Heating Equipment is designed for Pipeline, Vessel, Heat Exchanger, Chemical Reactor and Boiler. The vessels transfers heat to the fluid materials like Industrial Water, Oil, Gas, Food Material and Chemical Raw Materials heating. Heating Power size 2.5KW-100KW is the air cooled ones. Power size 120KW-600KW is the water cooled ones. For some on site chemical material reactor heating, We will supply the heating system with Explosion Proof Configuration and Remote Control System.
This HLQ heating system consists induction heater, induction coil, temperature control system, thermal couple and insulation materials. Our company provides installation and commissioning scheme. The user can install and debug by yourself. We can also provide on-site installation and commissioning. The key of power selection of fluid heating equipment is the calculation of heat and heat exchange area.
HLQ Induction Heating Equipment 2.5KW-100KW air cooled and 120KW-600KW water cooled.

Induction Heating Power Calculation
Required parameters of parts to be heated: specific heat capacity, weight, starting temperature and end temperature, heating time;
Calculation formula: specific heat capacity J/(kg*ĀŗC)Ćtemperature differenceĀŗCĆweight KG Ć· time S = power W
For example, to heat thermal oil of 1 ton from 20ĀŗC to 200ĀŗC within an hour, the power calculation is as follows:
Specific heat capacity: 2100J/(kg*ĀŗC)
Temperature difference: 200ĀŗC-20ĀŗC=180ĀŗC
Weight: 1ton=1000kg
Time: 1 hour=3600 seconds
i.e. 2100 J/ (kg*ĀŗC)Ć(200ĀŗC -20 ĀŗC)Ć1000kg Ć·3600s=105000W=105kW
Conclusion
The theoretical power is 105kW, but the actual power is commonly increased by 20% because of taking the heat loss into consideration, that is, the actual power is 120kW. Two sets of 60kW induction heating system as a combination are required.
