About this file
This is Addendum 1 for the Oregon Department of Corrections' solicitation S-29100-00013414 for the Warner Creek Correctional Facility (WCCF) Boiler Replacement project. The addendum formally modifies the original Invitation to Bid (ITB) and includes a substitution request for a heat exchanger, specifically approving a Hexonic heat exchanger in place of the originally specified Alpha Laval model. The substitution request was submitted by Pac West Sales Inc. on 6/3/25 and was approved by Jesse Swanson on 6/11/25. The technical documentation provided includes detailed calculation sheets and technical specifications for the Hexonic AJFB-015-P150-29 heat exchanger, which is designed for water-to-water heat exchange with specific performance parameters.
The heat exchanger specifications indicate a heat load of 537,421.8 BTU/h, with water inlet temperatures of 165°F and 55°F, and outlet temperatures of 100°F and 162.70°F. The unit is designed with a heat transfer area of 50.3 ft², can handle maximum pressures up to 150 psi, and is constructed with stainless steel 2" external thread connections. The design meets ASME BPVC Section VIII, Division 1 standards, with plates made of 0.5 mm 316L material and NBR HT gaskets. The addendum requires bidders to sign and return the document by the bid closing date, with failure to do so potentially resulting in bid rejection.
