Designed and built to:

TEMA C, B, or R designs in accordance with ASME Section VIII Div. 1 “U’ Stamp and NBBI Code “R” Stamp.

Quality Control capabilities:

PMI, Helium Leak, Dye Penetration & UT material and weld testing capabilities.

Metal constructed heat exchangers have become the material of choice in the fertilizer industry. Zirconium is preferred for its superior resistance to corrosion, temperature and pressure extremes.
