Atch 3 - AMENDED Equipment Salient Characteristics_8 Jun 26.pdf

This is an Amended Salient Characteristics document specifying equipment requirements for the replacement of fluid coolers and pumps in Buildings 590 and 591.

The solicitation requires three categories of equipment to meet existing infrastructure compatibility and facility cooling loads. For the fluid cooler (cooling tower), proposed equipment must meet or exceed the cooling capacity of the existing SPX ReCold MW-30C model, fit the existing structural support pad, operate on 208/230V 3-Phase power, include dual fans of approximately 3.0 HP each or equivalent configuration to achieve required cooling performance, and incorporate an internal basin heater of approximately 4.0 KW. Circulation pumps must deliver a minimum flow rate of 110 GPM, feature a 5 HP continuous duty motor with standard 4-pole speed rated at approximately 1750-1760 RPM, and operate on 208/230V 3-Phase power. The disconnect panel must be rated for 208/120V 3-Phase 4-Wire power, include a 100A 3-pole main disconnect breaker with two 20A 3-pole breakers to isolate the cooler and pump, and be housed in a NEMA 3R outdoor-rated enclosure. All proposed equipment must strictly adhere to these physical dimensions, electrical requirements, and performance specifications to be considered acceptable.
