About this file
This file is an attachment defining the salient characteristics and technical specifications for HVAC units required under a Request for Quotation (RFQ) issued by the Department of Agriculture Agricultural Research Service. The procurement (Solicitation Number 1232SA26Q0552) is for two Liebert MMD18A-PJE740AJN mini-mate units and one Liebert MMD36ENYJED40AE7 mini-mate unit with a PFH037A-YLN Prop Air Cooled Condensing Unit, classified as a supply purchase with no installation required. This is a small business set-aside acquisition under NAICS code 333415, with a small business size standard of 1,250 employees, and is a brand name or equal acquisition.
The two MMD18A-PJE740AJN units (1.5 tonnage each) must operate at 208/230 volts, 1 phase, 60 Hz with self-contained air-cooled systems featuring scroll compressors, hot gas bypass, two-speed blower assemblies, microprocessor controls, canister humidifiers (2.5 lbs/hr capacity), electric reheat, and compatibility with Liebert thermostat controls via the IS-UNITY-DP BMS monitoring solution. The single MMD36ENYJED40AE7 unit (3 tonnage) is a split system evaporator with MERV 8 box filter, two-speed blower, 4.3 lbs/hr canister humidifier, electric reheat, and the same Liebert control compatibility. The outdoor PFH037A-YLN condensing unit (3 tonnage) requires 208/230 volts, 3 phase, 60 Hz operation with a scroll compressor, hot gas bypass, and capability to operate in temperatures as low as -30°F. All units must maintain identical footprints to existing equipment, connect to existing ductwork and electrical points, and include freight and handling charges prepaid. Warranties must include a five-year compressor warranty and one-year entire unit parts warranty.
