Heating systems
Alexandria Engineering Industries designs and manufactures robust, energy-efficient heating systems tailored for industrial, commercial, and process applications. Our systems deliver precise, reliable, and safe thermal energy for oil processing, chemical plants, food production, asphalt facilities, and building climate control.
We specialize in indirect heating technologies—primarily thermal oil (hot oil) heating systems—as well as steam, electric, and hybrid solutions, ensuring optimal temperature control without direct flame contact or hot spots.
1. Thermal Oil (Hot Oil) Heating Systems
Applications
- Heating edible & mineral oil refining lines
- Bitumen melting and storage (160–200°C)
- Biodiesel reactors and distillation units
- Polymer modification (PMB) reactors
- Chemical processing requiring stable, high-temp heat (up to 320°C)
System Components
- Thermal Oil Heater: Fired (gas, diesel, or dual-fuel) or electric
- Circulation Pump: High-temp, magnetically coupled or mechanical seal
- Expansion Tank: Accommodates oil volume changes
- Heat Exchangers: Shell-and-tube or plate-type for indirect process heating
- Control Panel: PLC-based with safety interlocks (low flow, high temp, flame failure)
- Piping & Insulation: Prefabricated loops with mineral wool or ceramic insulation
Key Advantages
✅ High-Temperature, Low-Pressure: Operates at 300–320°C without high-pressure risks (unlike steam)
✅ Uniform Heating: Eliminates hot spots and thermal degradation
✅ Energy Efficient: >85% thermal efficiency with flue gas recovery options
✅ Safe & Clean: No open flames near process; closed-loop system
✅ Low Maintenance: Fewer corrosion and scaling issues vs. steam
2. Steam Heating Systems
For applications requiring rapid heat transfer or sterilization (e.g., food, pharmaceuticals).
- Boiler integration (fire-tube or water-tube)
- Steam distribution and condensate recovery
- Pressure-reducing stations and traps
3. Electric Heating Systems
Ideal for clean environments, small-scale processes, or zones with no fuel supply.
- Immersion heaters
- Heat tracing for pipelines
- Explosion-proof units for hazardous areas
4. Space & Facility Heating
- Industrial air heaters (gas-fired or electric)
- Radiant tube heaters for warehouses
- HVAC integration for control rooms and offices
Key Features Across All Systems
- Custom Engineering: Sized for your exact heat load (kW or kcal/h)
- Automation: Fully integrated with plant control systems (Modbus, Profibus)
- Safety Compliance: Meets ASME, PED, ISO, and local regulations
- Fuel Flexibility: Natural gas, LPG, diesel, or biofuels
- Remote Monitoring: Optional IoT connectivity for diagnostics and efficiency tracking
