CEXI Steam/Water Bath Vaporizer — 600K Capacity, 1000 PSIG

What utilities and footprint does this unit need on site?

This unit requires 90" x 60" of floor space with 120" height clearance. Water bath vaporizers typically need a steam supply or hot water circulation system sized to deliver the BTU load—in this case 8,108,258 BTU/hour—plus makeup water, drainage, and process piping connections at the rated 1000 PSIG. Ask the seller for the actual steam pressure and flow requirements, inlet/outlet connection sizes, and whether the bath uses steam injection or coil heating.

When does a water bath unit make more sense than ambient or electric?

Water bath vaporizers maintain steady output regardless of ambient temperature, making them the standard choice where steam is already available and flow demand is high or continuous. Ambient units derate severely in cold or humid climates and during extended duty cycles, while electric vaporizers may have higher operating costs at industrial scale. At 600,000 SCFH and 8,108,258 BTU/hour, this unit is sized for baseload or peak-shaving duty where ambient would be unreliable.

What maintenance does the bath and heat source require?

Water bath vaporizers require periodic bath water testing and treatment to prevent scale buildup on the coil bundle, which reduces heat transfer efficiency. Steam traps, control valves, and level controls need regular inspection, and the coil bundle should be pulled for cleaning on a schedule determined by water quality—typically annually in hard water areas. The pressure vessel itself follows standard ASME inspection intervals for the jurisdiction and service.

What should I inspect on a used water bath vaporizer before buying?

Inspect the coil bundle for scale deposits, pitting, or cracks, and verify wall thickness meets code minimums for the pressure rating—this unit is rated 1000 PSIG. Check all vessel welds, nozzles, and the bath tank for corrosion, verify the data plate is legible with ASME stamping if required in your jurisdiction, and review any documentation of hydrostatic testing or repairs. The listing states this unit has been inspected but not fully tested, so ask the seller for the inspection report and what testing remains to be completed.
