Russell Test Chamber Controller

The Defense Health Agency Contracting Activity seeks retrofit controllers for two Russell test chambers—Model RHB-64-705-705-AC (altitude and temperature) and Model WMD-336-ECMD-4-10-10 (walk-in thermal and humidity)—with quotations due June 9 and questions due May 8. This is a small business set-aside RFQ for commercial products under FAR Part 12. Deadline update: Amendment 0001 moved the quotation deadline to May 26 at 10:00 AM Local Time; questions are due May 8 at 2:00 PM Local Time.

Place of performance is Frederick, Maryland, with delivery required within 90 calendar days from award to Fort Detrick (DoDAAC HT0986). The scope includes controller acquisition, installation at both chambers, removal and replacement of the altitude chamber's mercury manometer with an altitude transducer, hazardous mercury waste disposal, and provision of engineering schematics for future maintenance and calibration. The upgraded controllers must enable chamber performance within Military Standard 810H, Change 1 tolerances.

The altitude chamber controller must deliver 4-channel minimum PID control, 6-loop programming, 15-segment temperature programming, altitude control to 100,000 feet, temperature control from -80 to 180°C with 1°C accuracy, data logging of 50 analog inputs at 1 per second with 200,000 reading minimum, remote control via LabView or Windows Remote Desktop, and calibration to 0.2 kPa or 5% of pressure reading. The thermal/humidity controller requires comparable specifications adapted for humidity (30–95% RH with 5% RH accuracy). Both require touchscreen displays and a minimum one-year parts warranty with 90-day labor warranty. Quoters must demonstrate past experience retrofitting Russell RH-series altitude chambers and Russell W-series walk-in thermal/humidity chambers.

Award will be firm fixed price for the controllers and installation, with Other Direct Costs (travel, training) at cost no fee. Evaluation criteria are Technical Capabilities/Specifications (conformance to Critical Operational Device Specifications), Past Performance (one to three references from projects completed within the last three years), and Price. Quoters must be SAM-registered at award and complete DFARS Provisions 252.204-7017 and 252.223-7001. NAICS 334513; PSC 6685. No incumbent identified.
