About this file
This document is a mechanical equipment schedule for NAVFAC Building 60 Repairs at Portsmouth Naval Shipyard in Kittery, Maine, showing detailed specifications for HVAC, heating, and related systems as of Amendment 009 dated March 16, 2026.
The schedules specify multiple equipment categories: Dedicated Outside Air Unit (DOAS-1) with energy recovery using a Trane CSAA010 unit rated at 3,260-3,200 CFM with DX cooling and hot water coils, equipped with MERV 13 outside air filters and ECM impeller fans; four split system outdoor condensing units (OU-1 through OU-4) using Trane-Mitsubishi PUY-AK12NL models with R-454B refrigerant, 12 SEER rating, 208-volt single-phase service, and 16 MCA/27 MOCP; three chilled water units (CU-1, CU-2, CU-3) using Trane 5TWA models with 48 or 42 MBH capacity at 460-volt three-phase; four indoor cassette units (IU-1 through IU-4) serving various building locations with capacities ranging from 1.0 to 7.0 tons; and accessory equipment including exhaust fans, steam pressure reducing valve (Leslie GPKP-1), condensate receiver and return pump (Bell & Gossett Model 23 CB9), circulation pumps with variable frequency drives (Bell & Gossett E-80), steam-to-water converter (Bell & Gossett SU-104-4), fintube radiation units (Vulcan brand), and makeup air louver (Ruskin/EUF6375DX). All equipment includes specifications for electrical requirements, refrigerant types, performance ratings, mounting details, and manufacturer-specific requirements such as coastal corrosion protection, vibration isolation, low ambient packages, and control systems. The document requires compliance with various notes addressing noise control, pressure turn-down ratios, duplex pump configurations, and leak detection systems.
