Statement of Work (SOW) Project: Growth Chamber

GENERAL INFORMATION

1.0 Scope of Work: BRU Rubber & Oil Seeds group requires a new growth chamber to replace one that has failed. Growth chambers are indispensable to our research because they allow the testing of various growth conditions for current research plant guayule and oilseeds for bio-material production.

2.0 Background: Growth chambers are needed to grow experimental plants for genetic testing.

CONTRACTOR REQUIREMENTS

The vendor will provide, deliver, and install the new growth chamber at the USDA, ARS, Bioproducts Research Unit at 800 Buchanan in Abany, CA 94710. The new growth chamber must meet the following technical specifications:

3.0 Technical Specifications

· The growth chamber is specifically designed for plant growth in containers.

· The growth chamber will be used daily in routine plant biology research where

· The growth chamber must allow setting of different temperatures and light intensities.

· The growth chamber must include wide range of temperate controls with lights on 7- 44 °C (±0.5 °C) and lights off 2-44 °C (±0.5 °C).

· Exterior dimensions must be W 41” x D 33.6” x H 77.2”

· Interior must have a total shelving area of 13.6 ft2 over two tiers.

· The growth chamber must have the same lighting and operating system as the existing growth chambers (LT-41VL)

· Must have inside volume of at least 37.2 cubic feet

· The growth space must be lighted by a single lamp bank consisting of programmable cool white SciWhite LED Tiles.

· Light intensity must be from 400 (bottom) up to 800 μmoles/m2/s of light irradiance (6” from the lamps) controlled by the IntellusUltra).

· The lighting must be SciWhite LED light spectrum, ideal growth condition for plants.

· The refrigeration & airflow system of the growth chamber must have a self-contained air-cooled condensing unit using a hot gas bypass for continuous compressor operation.

· The growth chamber heat rejection to ambient system must be approximately 3400 BTU/hr.

· The growth chamber must use a dual evaporator system to maintain low temperatures and avoid defrost temperature spikes.

· The growth chamber must have a system for conditioned air to circulate through a rear wall duct and picked up by a specially designed fixed air diffuser located at the bottom of each tier. Air must then be delivered vertically upward at a slow speed through each shelf.

· The growth chamber must include a 2 year warranty.
