Heat exchanger segment ORV


The most cost-effective large-capacity LNG vaporizers

Open Rack Vaporizer (ORV) contributes to the reduction of environmental impact as LNG vaporizer by using seawater as a heat source. KOBELCO, as one of the world’s top ORV manufacturers, has been improving its reliability for more than 40 years since Japan started importing LNG.


Environmentally-friendly & Cost-effective

  • Vaporize large volumes of LNG without creating CO2 emissions from combustion by using seawater.
  • Applicable to offshore (Jetty) installation.
  • Improved thermal spray coating enables long-term stable operation and savings in maintenance costs.

Existing Applications and Applicable Ranges

Abundant delivery record of more than 280 units as Base-load LNG vaporizers.

<Existing Applications>

  • LNG regasification terminal: LNG vaporizer
  • Others: LPG heater, ethylene vaporizer

<Applicable Ranges>

  • Temperature: -260 to 65°C
  • Pressure: 180 Bar(g) max.
  • Fluids: LNG, ethylene, ethane, propane, butane, liquid hydrogen, and other fluids non-corrosive to aluminum
  • Conditions: Restrictions for seawater quality (concentration of suspended solid and heavy metal ions)


Panel structure providing superior heat transfer performance

By using aluminum heat transfer tubes, ORV obtains excellent heat transfer performance and compact design. It has a unique "panel" structure in which heat transfer tubes are bundled in a plane, and cryogenic LNG (-160 degC) evaporates inside the tube. Since seawater flows down the outer surface of the panel, it enables restricting ice growth and stable heat exchange without blocking seawater flow.
See the detailed structure illustration below.
