About this file
This document appears to be a detailed set of specifications for a 20-ton air-cooled chiller unit required under a federal contract opportunity. The key specifications include: a scroll-type compressor, a 3HP chilled water pump, acceptable refrigerants, freeze protection, shell and tube or plated heat exchangers, microchannel condenser coils, low and high ambient temperature controls, refrigerant isolation valves, hail guards, flow switches, factory insulation, vibration isolation, and a BACnet/IP factory-mounted controller. The contract opportunity is for the Department of the Air Force Global Strike Command to procure 4300 of these skid-mounted chiller units. The solicitation number is FA466124Q0115. The contractor will be required to provide all labor, personnel, supervision, tools, equipment, transportation, and materials to deliver the specified chiller units to Dyess AFB.

Break down Salient Characteristics and Specs absolutely needed to fulfill the requirement.
Below is a breakdown of all mandatory components for building 4300 Skid Mounted Chiller.
ITEM
NUMBER DESCRIPTION QUANTITY UNIT
0001 20 Nominal Tons Air Cooled Chiller:
• Chiller must be 20 Tons
1 EA
Unit Mounted Main Disconnect:
• Panel will be 460-volt 60 hertz 3 phase – Single
Point Connections
Compressor:
• Compressors will be Scroll Type
Chilled Water Pump:
• Pump Size is no less than 3HP
Full Factory Refrigerant Charge:
• Acceptable refrigerants are R-545B, R-410A, HFC-134A
Freeze Protection:
• Requires separate 115v power supply
• Low ambient lockout to prevent chilled water lines from freezing
Heat Exchanger:
• Shell & Tube or Plated heat exchangers are acceptable for the chiller set up
Condenser:
• Must be Microchannel
• These coils have less depth and result in lower air pressure drop and better air flow transitions
Ambient Controls:
• Low ambient control to 0 degrees Fahrenheit
• Max ambient control to 115 degrees Fahrenheit
Refrigerant Isolation Valves:
• Discharge isolation valve is required for isolating compressor discharge
Hail Guard:
• Protective hail guard is required to protect condenser coil in the event of inclement weather
Flow Switch:
• Is needed to monitor and control flow rate of chilled water within the system
Factory Insulation:
• Needed to prevent surface condensation and moisture problems
Rubber and Shear Vibration Isolation:
• Will protect chilled water piping from vibrations produced by mechanical equipment
Factory Mounted controller:
• BACnet/IP data communication protocol is needed to allow the chiller to communicate with a building automation system
Skid Mount Base Plate:
• A skid base plate will be required to allow the
HVAC shop to move the chiller by means of 10K forklift
0002 Flexible Hose:
• Hoses will be no less than 50 feet and no more than 200 feet in length
• Hoses will include Camlok style fittings
4 EA
0003 MC Cable:
• Cable will be no less than 100 feet and no more than 400 feet in length with male/female connections
• Metal Clad Cable is required for corrosion resistance
4 EA
