Why an ID Vaporizer?
LP-Gas is stored as a liquid and used as a vapor. To change it into a vapor, heat must be added at the rate of: 785 BTU’s for each gallon of propane, 808 BTU’s for each gallon of butane. The liquid will then boil, changing to vapor at the rate of: 36.4 cubic feet for each gallon of propane, 31.3 cubic feet for each gallon of butane. LP-Gas liquid is supplied to the inlet of the ID Vaporizer from a suitable source. The liquid enters a header connected to a series of heat exchanger tubes which run through a warm water bath. This heats the liquid and converts it into vapor. The vapor is collected in a header at the top of the tubes, where it is drawn off to supply the needs of the application. The water is kept warm by a power burner mounted in a large immersion tube passing through the bath.
• Efficient propane combustion and consistent performance is maintained, since the power burner is substantially independent of weather conditions. Air is delivered to the combustion zone through the burner by a heavy-duty fan and is discharged through a diffuser specially designed to provide a firm flame anchor and stable, high-efficiency combustion. The resultant flame stability provides quiet operation, free from vibration, pulsation or flashback.
• A low, attractive silhouette is maintained in all sizes, since the power burner requires only a short slack and weather cap at the flue outlet. The neat rectangular housing is covered with stainless steel and blends well with any architectural setting.
• A continuous supply of dry, warm vapor is assured by providing additional heat exchange area over the amount required for rated capacity. The large water bath acts as a massive heat sink, eliminating the need to shut down while servicing power burner or controls.
• All critical components are protected from outside weather conditions to assure maximum reliability. These units are completely insulated for an economical operation.
• All models are built in accordance with Factory Mutual safety requirements.• Standard units feature safety interlocks which initiate automatic shut down sequence of power burner and activate dry alarn contacts and light in the event of excessive or insufficient burner gas pressure, excessive bath temperature, low bath level or flame failure.
• Integral liquid level control system prevents LP-Gas liquid from entering vapor line.
• Units are shipped ready for use, requiring only electrical power supply and connection of liquid and vapor lines.
1. Equipment, piping and installation must be in accordance with provisions of NFPA58, and all applicable state, provincial and local codes.
2. Liquid pump may be required to provide sufficient pressure to inlet of vaporizer during conditions of low tank pressure.
3. Outlet pressure regulator should be no more than 24 inches from vaporizer outlet and located at or above centerline of vaporizer outlet.
4. Do not install a separator, dripleg or other liquid trap upstream of outlet pressure regulator.
5. Regulator outlet pressure must be adjusted to a pressure below the vapor pressure of the saturated LP-Gas at lowest operating temperature or vapor may re-liquefy in downstream piping.
6. Liquid piping system must allow for occasional reverse flow toward supply tank to prevent excessive pressure during operation.
Standard units are built to Factory Mutual specifications, factory tested and calibrated, ready for use. Capacities are based on liquid inlet temperature of 20 degrees F and vapor outlet temperature of 100 degrees F, without use of pump, using HD-5 spec. propane (butane capacity available upon request).
(1) Units may be paralleled to achieve greater capacities.
NOTE: For usage with other liquified gases, consult factory sizing information. (i.e. C3H6, NH3, SO2, C12)
