Water Bath Vaporizers


TransTech Energy offers a comprehensive line-up of best-in-class water bath vaporizers for gasification of liquid Propane/LPG and butane in volumes that support a broad range of commercial, industrial and utility gas consumption operations.

We offer a broad range of water bath vaporizer capacities from 200 GPH (gallons per hour) to custom designed systems in excess of 12,000 GPH, to support virtually any size operation.   


Our free-standing, self-contained units are pre-wired, pre-piped and installation-ready for connection to your propane/butane liquid inlet supply, compatible electrical supply and gas outlet.     

Water bath vaporizers utilize a water- or oil-based heat transfer medium into which a heat exchanger for the heat source and another heat exchanger for the propane/butane liquid is immersed to facilitate heat transfer.  Often a gas fired burner is incorporated as the heat source, but hot water, steam, or electric heating elements may also be utilized.   

All units are ASME “U” stamped and National Board Registered.  Delivering consistent pressure and combustion, our water bath vaporizers ensure a continuous, dependable gas supply—for uninterrupted operations.   

Manufactured in strict compliance with the American Society of Mechanical Engineers (ASME) Section VIII, Div. 1 Boiler & Pressure Vessel Code, UL or FM and the latest edition of NFPA 58 and/or 59, we stand behind every water bath vaporizer we deliver— and you can rest assured in the safety and reliability of your LP gas/butane gasification system.
