Apex Engineered Products Facilities.

Apex Engineered Products is a proven supplier of heat transfer equipment primarily to the Nitrogen and Phosphorus based Fertilizer Industries and the General Chemical markets. Material compositions include Reactive Metals ( Ta, Ti, and Zr ), Ni Alloys ( VDM Alloy 31®, Hastelloys®, Inconels® ) and Duplex and Austenitic Stainless Steels; all of which offer resistance to highly corrosive processing materials during extreme pressure and temperature operating conditions.

Apex is a 32,000 ft2 manufacturing facility located in western Pennsylvania. It occupies 2 buildings that include production, engineering, sales, and management. Carbon Steel and Reactive Metal fabrication are located in separate buildings to prevent cross contamination, and a segregated “clean room” is designated for welding Reactive Metals.  

Our Ammonium Nitrate & Fertilizer Producing Customers:

JR Simplot, Dyno Nobel, PCS Phosphates, PCS Nitrogen, Agrium, DSM, and CF Industries. These customers have all returned to Apex for additional heat exchanger requirements.

Our General Chemical & Metal Finishing Customers:

Axiall, Emerald, Ashta Chemicals, Evonic, BleachTech, Dover Chemical, Olin Chlor Alkali Products, Vertellus, Arkema, Cal Energy, US Magnesium, Cargill, to name a few.

Alloy 31 for Ammonium Nitrate and Fertilizer Industry.

Our primary product lines focus on the nitrogen / ammonium nitrate, and phosphorus based fertilizer industries.

These include: Coolers / Condensers, Product & Gas Heaters/ Reheaters, Evaporators, Vaporizers, Reboilers, and Vessels.

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.
