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
Electrical Heating Advantage
- 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 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
AISI 304In water or humid environment max. 450°C. In air max. 700°C.
Scaling temperature: 850°C.
For food industry.AISI 321n water or humid environment max. 550°C.
In air max. 750°C.
Scaling temperature: 850°C.
Tube for washing and cooking heating elements.AISI 316LEquivalent to AISI 316, with addition of molybdenum. Besides improving resistance to corrosion and under tension, there is a better response to general corrosion. In water or corrosive humid environment max. 450°C. For food industry. Incoloy 800In water and air with max. Temperatures of 1050°C. Annealing temperature of heating element 1100°C.Incoloy 825In air for max. Temperatures up to 1100°C. In water or highly corrosive environments.Inconel 600Finer refractory alloy with excellent resistance to corrosion. In air up lo 1250°C.
- Design the Flange Heater
We design a bespoke heater for the customer’s application according to the size of the tank.
- Design the CIRCULATION Heater
We design a bespoke heater for the customer’s application according to the space available on site
-
- Step 4: Control Selection
Temperature control is accomplished by one of two methods :
Control Thermostats
Used for :
- Standard applications when accuracy is not very important (±10ºC).
PT100 sensors or Thermocouples(Type J,K)
Used for :
- 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
