Temperature Chamber

Background
The Naval Surface Warfare Center (NSWC) Crane is issuing a competitive solicitation for the procurement of two Temperature Chambers. This requirement is part of their mission to support naval operations through advanced technology and equipment. The goal of this contract is to acquire temperature chambers that meet specific government specifications for testing and evaluation purposes.

Work Details
Contractors are required to deliver two Temperature Chambers that meet the following specifications:
- Temperature Range: -54 to 180 °C (preferred range is -70 to 180 °C)
- Temperature Change Rate: Rated for 5 °C/min or higher when cycling from -34 °C to +71 °C, and from +71 °C to -34 °C; preferred ramp rate is 5.4 °C/min or higher, with 5 °C/min being the minimum acceptable.
- Transition Times: Complete the transition from steady state -34 °C to steady state +71 °C in 21 minutes or less (preferred 19.4 minutes or less) and from +71 °C to -34 °C in the same time frame.
- Port Holes: At least one 4-inch diameter (or larger) cable port.
- Over-heat Protection: User-set limit.
- Viewing Window: Required.
- Temperature Control: Required.
- Humidity Control: Not required.
- Interior Volume: 16 cubic feet or larger.
- Exterior Dimensions: Width ≤ 60 inches, Height ≤ 90 inches.
- Power Supply Source Options: 230V 3-phase 60Hz (up to 80A), 230V 1-phase 60Hz (up to 40A), or 120V 1-phase 60Hz (up to 20A).
- Temperature Controller: Must not use Watlow F4 Controllers; must be equivalent to a Watlow F4T or CSZ EZT-570.

Incumbent Analysis (see Incumbents section for more detail)
This opportunity appears to have a confirmed incumbent and/or closely related prior contract, with Russells Technical Products identified on multiple Crane temperature chamber awards (e.g., N0016425DS001 valued at $178,500 for 8 cu-ft basic temperature chambers and related variants, and additional temperature chamber work under N0016423PJ182). The prior efforts involve manufacture and delivery of temperature chambers to Crane, including basic configurations and multiple models/sizes, which aligns with the current requirement to procure two temperature chambers meeting specified performance characteristics (temperature range/ramp rates, transition times, and required ports/viewing).
