CONSTRUCTION
–Exterior Dimensions: 120”W x 70”D x 102”H (Control box adds 7” to chamber depth and roof mounted condensing unit adds 24” to chamber height)
–Interior Dimensions: 99.3”W x 62”D x 84”H
–Growth Area: 42.7 sq.ft.
–Growth Height: 84” between perforated aluminum channel floor and the lamp bank barrier
-Light Fixture: Fixed light fixture is separated from the chamber growth space via a thermal barrier (light fixture has an independent temperature control system from the chamber [lamp heat exchangers are provided to dissipate lamp heat])
-Insulation: The insulation shall be “foamed-in-place” polyurethane with 97% closed cell structure and in-place density of 2.2 lbs per cubic foot. Overall thickness shall be 4” with an R factor of 32. The polyurethane insulation must retain dimensional stability in an operating temperature range of -40C to 121.1C.
-Door: The room has two front doors (each door is a flush type for a 32” x 78” door opening). Provided with a magnetic snap-in perimeter gasket, self-closing cam lift gravity hinges, a Posi-Seal door closure and a key lockable latch handle with an inside safety release. Door jambs are made of fiberglass reinforced plastic. Doors include an interior safety release. Both doors are also provided with a thermal pane window and hinged, gasketed cover.
-Observation Window: A thermal-pane 14” x 14” window is provided for interior viewing. A light tight cover is provided.
-Cabinet Construction: All rooms are built in panel sections.
-Each section consists of 4” thick urethane insulation, metal interior and exterior surfaces, cam-type fasteners and vinyl gaskets
-Panels are manufactured in one-foot increments up to a maximum of four feet wide
-Standard corner sections are 90 degree angles with either 12”x6” or 6”x12” sides
-Panel edges are made by molding tongue and groove to facilitate assembly
-A balloon type, NSF-listed PVC gasket is permanently foamed in place on opposite sides of tongue edges to accomplish an air-tight seal between panels
-Panels are joined by engaging Posi-Locs embedded into the insulated panel edges (Posi-Loc access holes are covered with vinyl snap caps)
-All interior corners and floor-wall-ceiling joints shall have a 3/8” radius for ease of cleaning
–Finish: Standard metal exterior is 26-gauge embossed white galvanized steel, interior wall and ceiling surfaces are 24-gauge smooth steel with a baked white enamel finish (other optional metals are available upon request) (standard exterior ceiling metal is 26-gauge galvalume steel)
-Floor: Insulated floor provided with center drain exiting either at front or rear of chamber
-Instrument Ports: Two 1” diameter ports provided through front wall
LIGHTING
-Light Intensity: Up to 1000 micromoles/m2/sec at 6” from lamps
–Lamps: Balance spectrum for plant growth using T-5 fluorescent lamps plus extended life tungsten incandescent lamps
–Programming and Control: Photoperiod is programmable via real time controller (five programmable levels of fluorescent lighting and two programmable levels of incandescent lighting)
-Canopy Barrier: A transparent barrier, located between the lamp canopy and growing space is provided to promote temperature uniformity within the growing space. Barrier is optimized to allow light into the growing space, while containing a majority of the heat produced by the lamps within the canopy. Barriers may easily removed for cleaning or replacement.
-Light Reflector: Specular aluminum light reflectors
–Light Fixture Temperature Control: Patent pending lamp bank that is specifically designed to optimize energy efficiency by managing the heat inside the lamp bank. Design produces a constant light irradiance throughout the chamber’s temperature range. Lamp heat exchangers are provided to dissipate lamp heat. An independent temperature controller will keep the lamp bank at the bulb’s optimal operating temperature.
-Light Fixture Design: Patent Pending Design (filed January 9, 2007, U.S. Serial No. 11/621,412)
COOLING/HEATING SYSTEM
-Chamber provided with hot gas bypass refrigeration system to provide heating and cooling.
-Condensing Unit: Water-cooled, located on chamber roof
-Refrigeration Valves: Solenoid type with extended stem for long life and quite operation
-Compressor Type: Scroll
-Refrigerant Type: R-134a –
Heat: Via hot gas and electric heaters
-Chamber Growth Space Evaporators: Dual evaporator’s designed (one coil in each side wall of the chamber to maximize chamber performance)
-Light Fixture Evaporators: Two lamp heat exchangers are provided to dissipate lamp heat. Heat exchangers are independent from the chamber growth space evaporators. An independent temperature controller and valves will keep the lamp bank at the bulbs optimal operating temperature.
AIRFLOW
–Air Flow: Uniform vertical (upward) airflow through the perforated aluminum channel false floor
–Fresh Air: Adjustable forced air exchange system to provide up to 20 air exchanges per hour of fresh air to the room
