FLIGHT LINE AIR CONDITIONING/HEATING UNIT

The United States Coast Guard (USCG) has a requirement for Flight Line Air Conditioning/ Heating Units. All quotes must meet or exceed the requirements listed below.

Quotes will include price (to include a price breakdown of any optional items), pictures of item or similar item, lead time and shipping costs. F.O.B. Destination is requested as the F.O.B. point for all deliverables. All offers will be considered F.O.B. Destination unless F.O.B. origin is specified AND shipping costs are included.

Offerors shall fill out the attached spreadsheet titled “HSCG38-11-Q-500036 Technical Criteria” to ensure their product meets or exceeds the USCG’s minimum requirements. Offerors may also include any additional information necessary to fully describe the Air Conditioning/Heating Unit they are able to provide. All information provided will be used by the USCG to determine the offer that provides the best value in accordance with the evaluation criteria of this solicitation.

Flight Line Air Conditioning/Heating Unit Use:

The Flight Line Air Conditioning/Heating Units are required to be used under continuous operation to provide cooling of the HC-144A (CASA) aircraft cockpit, cabin and cargo compartment. The unit must be capable of maintaining the aircraft comfort to below 80 degrees Fahrenheit in the summer and above 60 degrees Fahrenheit in the winter. The units shall not require an air-return from the aircraft and carbon monoxide shall not be present in the output airflow of the unit in any operational mode. The unit shall be delivered with a full charge and shall meet the best commercial practices for aircraft ground support equipment.

Please contract Crissy Taber at Crystal.G.Taber@uscg.mil with any questions regarding this solicitation.

The specifications below represent the minimum requirements.

Design Specifications:

· Cooling Capacity – approximately 24 Nominal tons

· Air Flow – 190 lb/min

· Supplied Air Temperature (@100°F & 50% RH) – 35-50 °F

· Heating Capacity – The current Air Conditioning/Heating Cart used by the United States Coast Guard (USCG) has a 275,000 btu/hr capacity in the heating mode and 288,000 btu/hr in the cooling mode. The USCG’s requirement is for a 24 ton unit. The unit must be able to simultaneously cool/heat two HC-144A (CASA) aircraft. If the btu/hr needs to be less due to new EPA restrictions or other reasons, please provide that information in the quotation and confirm that the btu/hr rating of the respective Air Conditioning/Heating Cart will meet the USCG’s need.
