1.3 Key Features and Benefits of the HX2
• The HX2 safety system includes a pressure/temperature (P/T) relief valve, solenoid-
operated, fail-open dump valve, and an automatic fail-closed steam inlet control
valve.
• Lightweight, compact design fits through standard doorways and freight elevators.
• High accuracy temperature control of ±4 °F achieved.
• Continuous forced re-circulation eliminates temperature stratification and ensures a
uniform temperature distribution across all temperature sensors while also reducing
scaling and sediment build-up on the tube bundles in the process.
• ASME constructed and stamped tank assures safe operation to 150 PSIG.
• All wetted parts on the heated side are lead-free and comply with NSF Standard 61
and the requirements of the U.S. Safe Drinking Water Act.
•
Support stand can comply with International Building Code (IBC) guidelines for
seismic requirements.
1.4 Materials of Construction
The standard HX2 tank and couplings are 316L stainless steel passivated to ASTM A380
and A967. Piping is carbon steel, welded or threaded as appropriate. All units come with
a flexible insulation jacket conforming to ASHRAE Std. 90.1, and the support stand and
heating bundle head are powder coated for added durability.
