Tri State Fertilizer • Agriculture • RIDGLOK® Fertilizer Tank Insulation • Fairmount, ND


Tri-State Fertilizer, LLC Terminal located in Fairmount, ND is a joint venture between Farmers Union Oil of Southern Valley and Minn-Kota Ag Products.   The plant’s capability to store large amounts of fertilizer is a direct benefit to the grower, providing the assurance that the product will be there when it is needed and also at a more competitive price.  

This RIDGLOK® Vertical Standing Seam Panel Insulation System was installed on a ground storage tank for Tri State Fertilizer located in Fairmount, ND.   The welded tank was utilized to store fertilizer premix for the plant.   

The RIDGLOK® Insulated Panel System was installed on a 52’ diameter x 32’ high welded tank.  The system consisted of 0.024 stucco-embossed aluminum metal jacketing in black laminated to 2 layers of 2.0” polyisocyanurate insulation board with an R-value of 23.9 using a cone roof system.

The project was satisfactorily completed on 11/25/2015.  The site foreman stated that he would recommend both the install crew and the RIDGLOK® Panel System to others.
