- HEATING FUNDAMENTAL
- ELECTRICAL HEATING DESIGN
- Step 1: Establish Design Parameters
- Step 2: Determine Heat up power and Heat Losses
- Step 3: Design the heater
- Step 4: Control Selection
- INSTALLATION
- Most industrial facilities will have electrical power available
- A variety of types and methods of electric heating may be used to maintain a broad range of temperatures for process systems and associated equipment.
- The advantages of electricity include better controllability, no emissions and low capital equipment cost
- Simplified installation and reduced operation and maintenance costs.
- Over its history, electric tracing has proven to be a safe choice for process systems and equipment heating.
ELECTRICAL HEATING ADVANTAGE
- ELECTRICAL HEATING DESIGN
- Step 1: Establish Design Parameters
Tank/ Process details
- of the Tank
- Medium to be heated
- Mass or Flow Dimensions
Temperature
- Min and Max Ambient Temperature
- Start-up Temperature
- Final Temperature
- Time required to reach Final Temperature
Electrical
- Electrical area classification
- Circuit Breaker capacity
- Operating Voltage
Tank’s Insulation
- Type
- Thickness
- Step 2: Determine Heat up power and Heat Losses
- SAFETY FACTOR CONSIDERATIONS (1,2)
- Thermal insulation degradation
- Supply voltage variations
- Branch wiring voltage drop
- Heating device voltage drop (if applicable)
- Increased radiation and convection on higher temperature applications
- Quality of installation of thermal insulation
- Step 3: Design the heater
- SELECT THE PROPER MATERIALS FOR THE DESIGN
In order to determine the correct materials to the application the following information will be necessary
- Working temperature
- Max. exposure temperature
- Material of the Vessel or Tank
- Supply voltage
- Chemical environment
- Area classification
- Heat requirement
- SELECT THE PROPER SHEATH MATERIAL FOR THE DESIGN

- DESIGN THE FLANGE HEATER
We design a bespoke heater for the customer’s application according to the size of the tank.
- مرحله چهارم : اStep 4: Control Selection
- Standard applications when accuracy is not very important (±10ºC).
Temperature control is accomplished by one of two methods :
Control Thermostats
Used for :
- سنسور یا ترموکPT100 sensors or Thermocouples(Type J,K)
- Process maintenance applications where The process temperature must be controlled Within a moderate or narrow band.
- INSTALLATION
- Easy Installation of our systems, “plug & play”
- A manual for installation, operating and maintenance is always supplied
Used for :
