Installation Steps for Electric Heating Thermal Oil Heaters

The installation steps can be divided into main phases: preparation, equipment installation, piping connection, electrical connection, commissioning, and inspection. Here are the detailed steps:

1. Preparation

Thorough preparation is essential before starting installation. This ensures smooth progress and reduces risks.

1.1. Equipment Acceptance & Inspection

Inspect the heater upon delivery.
Check for any transport damage.
Verify all accessories are present (heating elements, temperature controls, pump, electrical parts).
Confirm specifications match requirements (model, rated power, voltage, current).

1.2. Equipment Storage

Store the approved heater in a dry, ventilated area.
Protect it from moisture and contamination.
Keep electrical components especially dry.

1.3. Site Preparation

Choose a level, solid foundation.
Ensure no ground settlement or movement risk.
Provide sufficient space for installation, maintenance, and operation.
Keep the area free from flammable materials.
Prevent water accumulation.

2. Equipment Installation

2.1. Foundation Work

Prepare a suitable concrete foundation.
Base it on the equipment weight and dimensions.
Follow the design for foundation height.
Allow concrete to cure fully (usually 48+ hours).

2.2. Placing the Equipment

Position the heater on the foundation.
Ensure it is stable and level.
Use a spirit level to check.
Adjust with shims if needed.

2.3. Securing the Equipment

Fix the heater to the foundation securely.
Use expansion bolts or suitable fasteners.
Prevent any movement.

3. Piping Connection

3.1. Inlet/Outlet Piping

Connect to the thermal oil system according to drawings.
Ensure smooth pipe routing to/from heater ports.
Use suitable high-temperature pipe materials (e.g., stainless steel).
Ensure all connections are leak-tight (flanges, threaded).
Install pipe supports for long runs. Prevent sagging.

3.2. Installing the Oil Circulation Pump

Install the pump correctly. It is vital for oil flow.
Ensure pump ports align smoothly with pipes.
Prevent air ingress into the pump.
Use flexible connectors at pump connections. Absorb thermal expansion stress.
Check pump rotation direction is correct.
Use proper seals.

3.3. Installing Safety & Vent Valves

Install a safety valve. Prevent system overpressure.
Install vent valves. Remove air from the system.

4. Electrical Connection

4.1. Power Supply Connection

Connect to the correct three-phase power supply.
Ensure voltage and frequency match equipment specs.
Install suitable electrical switchgear. Include circuit breakers and overload protection.
Follow electrical safety codes. Avoid shorts or overloads.
Use appropriately sized cables. Match the rated power.

4.2. Control System Connection

Connect the control system wiring (temperature, level).
Ensure control power is connected correctly.
Verify all control components function.

4.3. Grounding (Earthing)

Connect a reliable equipment ground (earth).
This is critical for electrical safety.
It protects against electric shock and fire.

5. Commissioning & Inspection

5.1. Initial Checks

Check all pipe connections are tight. No leaks.
Verify all electrical connections are safe.
Test power supply and switches work.
Ensure temperature sensors and controllers are installed correctly.

5.2. Pre-Start Checks

Fill the system with clean thermal oil. Remove impurities.
Confirm the oil circulation pump runs normally.
Check control system settings match design.
Verify safety and vent valves function.

5.3. Start-up & Commissioning

Start the heater system.
Monitor parameters for stability. Look for abnormalities.
Observe oil temperature rise. Ensure heating works.
Gradually increase the load during testing.
Check system stability and safety.

5.4. Operational Checks

Verify temperature control stability.
Check oil circulation flow rate is normal.
Ensure oil distributes evenly.
Confirm safety devices work (over-temperature, over-pressure protection).

6. Summary
