Atch 3 - Equipment Salient Characteristics.pdf

This document is a Salient Characteristics specification for fluid coolers and pumps replacement in Buildings 590 and 591. The specification establishes strict requirements for acceptable "equal" products to ensure compatibility with existing infrastructure and adequate facility cooling loads.

The fluid cooler (cooling tower) must meet or exceed the cooling capacity of the existing SPX ReCold MW-30C model, operate on 208/230V, 3-Phase power, feature dual fans of approximately 3.0 HP each (or equivalent configuration meeting required cooling performance), and include an internal basin heater rated at approximately 4.0 KW. Circulation pumps must deliver a minimum flow rate of 120 GPM, utilize a 5 HP continuous duty motor with standard 4-pole speed (approximately 1750-1760 RPM), and operate on 208/230V, 3-Phase power. The control panel must be rated for 208/120V, 3-Phase, 4-Wire power with protection consisting of one 100A breaker and two 20A 3-pole main breakers, housed in a NEMA 3R outdoor-rated enclosure. All proposed equipment must strictly adhere to these physical dimensions, electrical requirements, and performance capabilities to be considered acceptable replacements.
