About this file
This document is a Questions and Answers (Q&A) spreadsheet for Solicitation FA4626-25-Q-0019, which seeks the procurement of four HVAC chillers for Malmstrom Air Force Base in Montana. The chillers include one 70-ton unit with a cold start and dry cooler, one 90-ton chiller, one 40-ton chiller, and one 50-ton chiller, with specific technical requirements including air-cooled outdoor units, 208V 3-phase 60 Hz power, and propylene glycol/water processing fluid. Key specifications include a chiller setpoint of 45 degrees, design flow of 210 gpm, entering temperature of 54 degrees, and leaving temperature of 44 degrees, with an ambient air temperature of 95 degrees.
The Q&A document clarifies critical details such as no installation required, delivery to 341 CES at Malmstrom AFB, factory startup needed, and no specific brand preference. Voltage, power, and technical specifications were extensively discussed, with vendors seeking clarification on equipment details. The solicitation is for comfort cooling purposes, with a delivery deadline that allows for current market lead times. The procurement is managed by the Department of the Air Force Global Strike Command, with questions due by April 27th and an emphasis on meeting the specified technical requirements for the HVAC units.
