Ambient / Air Heated Systems
CEXI builds a full line of vaporizers for both process and disposal applications. We have a proprietary extended surface design that we use for process applications. We build units up to 200,000 scfh in a single unit. We provide a full line of accessories including cycling systems and trim heaters for ambient applications. We also have an active system for defrosting the vaporizers and can provide continuous duty ambient systems for large flows that take up relatively small floor space. We utilize both natural convection and forced convection heat transfer for the vaporizers. In the disposal vaporizers, we provide continuous duty units that have protection against ice ejection and fan damage. We can provide large flows in single units - up to 1,000,000 cubic feet per hour.

Steam Heated Systems
CEXI builds two lines of vaporizers using this medium. We build the conventional shell and tube style unit that has very high capacity in a small unit. We also build water bath units that are more reliable and allow for the thermal expansion that is such a problem in the shell and tube style units. We also build a line of steam heated trim heaters for gas heating applications.

Electrically Heated Systems
CEXI builds several styles of electrically heated systems. This includes pressure build vaporizers for maintaining tank pressure as liquid is withdrawn, process vaporizers, and trim heaters. We build several different types of units. We build units that have aluminum as the heat transfer agent, water as the heat transfer agent, and directly heated designs.

Water Bath Designs
CEXI builds systems that are able to utilize the waste heat found in many industrial applications. By doing this we are often able to save the customer substantial money in energy costs. We are able to utilize water all the way down to 35^oF for the heat source. We can also use high temperature high pressure water for the heat source. We generally use a shell and tube style design for these applications, however tank style designs are available.

Gas Fired Systems
CEXI builds gas fired systems in two basic styles. One type of system utilizes a packaged boiler or boilers from reputable manufacturers to provide heat to a water recirculation loop that then heats a vaporizer. Another style of unit heats the water via a boiler built directly into the vaporizer shell.

Final Line Regulator Stations
CEXI builds final line regulator stations to suit customer needs and requirements. We build everything from hospital dual redundant systems to large industrial systems that are fully instrumented.

Systems
CEXI has the capability to design and build pump and vaporizer systems that are custom designed to meet the needs of the customer. We have designed and built custom systems for Rockwell, Air Liquide, BOC, Lockheed, Martin Marietta, Korea Gas and Praxair. We build all of our system in house so we are able to control the costs and make sure that the design meets the customer requirements. We have full capability with PLC's and data logging equipment. We are familiar with the NFPA and FDA requirements for the systems. We are also familiar with hazardous location requirements and build equipment that meet the requirements for installation in hazardous locations.
