Vertical Thermal oil heater OMDV

Great design flexibility

• Operating options:
  • Two-stage: two potentials and two burner flames, operation at 50% and 100% power.
  • Modulating: continuous power modulation by inverter, from a minimum of 30% to a maximum of 100%.
• Customizable accessories according to customer's specific needs.
• Single or multiple lead internal coil, designed in function of thermal power. Large exchange surface, for a uniform heating of oil.

High quality standards

• Inner tube bundle made by two concentric coils manufactured from P235GH/P265GH (eq. ASTM A106 Gr. B) carbon steel pipes, designed to maximize heat exchange surface between oil and flue gas.
• The inside of the lower diameter coil represents the combustion chamber. The entire tube bundle rests on a layer of refractory material for optimal insulation.
• The large upper door can be removed for inspection and maintenance. The special fastening system ensures perfect sealing of the flue gas lap and optimal thermal efficiency even after many openings of the combustion chamber. 
• Body insulation by refractory ceramic fibers and an external stainless steel sheet layer.
  Use of refractory material is limited and is concentrated only in the highest temperature areas. Thermal inertia is reduced, so that the risk of overheating or degradation of the oil in case of an emergency heater shutdown is reduced as well.
• Internal collectors provide an even flow distribution inside the coils.
• Inlet and outlet flanged connections PN16.

Complete and functional control panel

Each machine comes complete of the electromechanical cabinet. It integrates the control panel complete of all buttons, selectors, digital controllers necessary for operating. Main features are:

• Main power switch.
• Auxiliaries on/off selector switch.
• Pump on/off switch.
• Burner on/off selector switch.
• Manual lockout reset button.
• Digital temperature controller for continuous monitoring of inlet and outlet oil temperatures.
• Dedicated indicator lights for each of the possible anomalies (safety temperature switch, motor protection switch, differential pressure switch, chimney lockout, min oil level inside expansion tank lockout, burner lockout). 
• Customization available (additional probes, digital PLC, remote control and block signals, burner flame ignition counter, etc.).
