About this file
This document is a Salient Characteristics specification for a 15-ton commercial direct expansion (DX) split air conditioning system, establishing minimum requirements for acceptable "equal" products in a federal procurement.
The requirement specifies a matched AHRI-certified system with nominal capacity of approximately 180,000 BTU/hr, powered by 208/230V, 3-phase, 60Hz electricity. The system must use EPA-compliant, low-GWP refrigerant R-454B (R-22 is explicitly prohibited) and meet or exceed current DOE minimum SEER/IEER energy efficiency ratings. The air-cooled condensing unit must feature a scroll-type compressor with internal thermal overload and pressure safety controls, microchannel or copper/aluminum condenser coils with corrosion resistance treatment, factory-installed louvered panels or hail guards for physical protection, and be rated for efficient operation up to 115°F ambient temperatures. The air handling unit must include an insulated galvanized steel cabinet, a blower motor capable of meeting existing ductwork static pressure and CFM requirements, a direct expansion evaporator coil with thermostatic expansion valve (TXV) or electronic expansion valve (EEV), and a factory-installed filter rack designed for 2-inch MERV 8 filters to ensure compatibility with existing facility infrastructure and cooling loads.

SALIENT CHARACTERISTICS
Requirement: 15-Ton Commercial DX Split System (Condensing Unit and Air Handling Unit)
To be considered an acceptable "equal" product, all proposed equipment must adhere to the capabilities outlined below to ensure compatibility with existing infrastructure and meet required facility cooling loads.
1. System-Wide Requirements
• Nominal Capacity: 15 Tons (Approx. 180,000 BTU/hr).
• System Certification: Must be an AHRI-certified matched set.
• Refrigerant Type: EPA-compliant, low-GWP (R-454B). R-22 is not permitted.
• Power Supply: 208/230V, 3-Phase, 60Hz.
• Energy Efficiency: Must meet or exceed current DOE minimum SEER/IEER ratings.
2. Air-Cooled Condensing Unit (Outdoor Unit)
• Compressor: Scroll type with internal thermal overload and pressure safety.
• Condenser Coils: Microchannel or copper/aluminum with corrosion resistance treatment.
• Physical Protection: Factory-installed louvered panels or hail guards.
• Ambient Operation: Rated for efficient operation up to 115°F.
3. Air Handling Unit (Indoor Unit)
• Cabinet: Insulated galvanized steel to prevent condensation.
• Blower Motor: Must meet existing ductwork static pressure and CFM requirements.
• Coil Type: Direct Expansion (DX) evaporator coil with a TXV or EEV.
• Filtration: Must include a factory-installed filter rack for 2-inch MERV 8 filters.
