About this file
This is a Performance Work Statement (PWS) for a service contract with the Department of the Navy at Puget Sound Naval Shipyard in Bremerton, Washington. The contract requires delivery and rental of one portable water chiller unit with 100-ton nominal and design refrigeration capacity, air-cooled and electrically powered, to support production comfort cooling during maintenance on a submarine during the JCD project availability. The contract period runs from October 19, 2026, through August 23, 2028, with an available two-month extension from August 24, 2028, to October 23, 2028.
The chiller must supply a minimum 300 GPM with 40 psi pressure loss, operate continuously from no load to 100 tons with automatic compressor and recirculation valve control, maintain chilled water temperature at 42°F with a 10°F temperature difference, and be capable of modulating within a 1°F band between 40°F and 50°F. Equipment noise must not exceed 90 dBA per ANSI S12.16. The chiller package must be self-contained, suitable for outdoor marine environments, and include two 300 GPM pumps, a 500-gallon surge tank, isolation valves, hose assemblies, automatic bypass recirculation valve, strainer, electric condenser fans, and self-regulating controls requiring monitoring only once every three days. The contractor is responsible for delivery by October 19, 2026, setup within 48 hours, startup training for three government personnel, all maintenance and repairs, providing operating instruction manuals, hose hydrostatic test reports, 24/7 on-call repair service with 24-hour response time, and emergency replacement or repair within 96 hours of notification. The government will provide electrical power, freshwater supply, and connection of chilled water supply and return hoses. Contractor shall arrange all delivery logistics and comply with General Occupational Safety requirements and FAR clauses including Combat Trafficking In Persons compliance.

PERFORMANCE WORK STATEMENT (PWS)- SERVICE
CONTRACT
2026/2028
JML #: 52801352
RCP#:
Ship/Activity: XXXXXXX Title: Rental Chiller and accessory equipment to support production corrifort cooling Place of Performance: Puget Sound Naval Shipyard, Bremerton, WA.
Period of Performance: From 10/19/2026 through 08/23/2028 with an available option for a two (2) month extension 08/24/2028 to 10/23/2028
REFERENCE:
(a) Local Standard Item 099-0lNW, General Occupational Safety
1. BACKGROUND: In support of maintenance being conducted on (XXXX) during the JCD project availability, PSNS & IMF requires one (1 ea.) portable water chiller unit capable of 150- Ton capacity, air-cooled, with accessory equipment. The chiller will be installed in the weather in the dry-dock basin next to a submarine to provide chilled water (CW) to portions of the ship with widely varying chilled water flow rates and heat loads. The contract shall also include setup, startup assistance, operator training, and all maintenance.
Throughout this specification, the completed system, including all components, is referred to as "the chiller".
2. SCOPE: The chiller and accessory equipment shall be delivered and set up by the contractor.
The vendor shall provide training to three government personnel who shall operate the equipment during the rental period and change the chilled water filters as needed. All other maintenance and repairs shall be the responsibility of the vendor. The government will connect electrical power to the chiller and pumps, connect temporary freshwater to the surge tank and connect the supply and return hoses to the government distribution system.
2.1 Chiller supply parameters:
2.1.1 The chiller shall be rated for at least a 100-ton nominal and 100-ton design refrigeration capacity and shall be capable of supplying at least 300 GPM with a pressure loss of 40 psi in the customer loop (i.e. from the chiller CW discharge to the chiller CW inlet). The chiller shall be capable of being operated from no cooling load up to 100-tons continuously where compressors shall automatically come on and off line as required and the automatic recirculation valve shall open to maintain the required minimum flow through the chiller during low flow conditions and close during high chill water demand conditions. The water to be chilled is freshwater.
2.1.2 The chiller controls shall be capable of being adjusted to supply chilled water at a temperature of 42°F with a temperature difference (Delta T) of 10°F. The controls shall be capable of being adjusted to maintain the temperature within a 1 °F modulating band between 40 and 50°F.
2.1.3 Only equipment generating 90 dBA or less when tested IAW ANSI S12.16 is acceptable. The contractor shall identify any product being offered that is certified as a low-noise-emission product per 42 USC 4907."
