CONSTRUCTION
*Exterior Dimensions: 96”W x 108”D x 102”H (Control box adds 7” to chamber depth and roof mounted condensing unit adds 24” to chamber height)
*Interior Dimensions (growth volume): 82”W x 100”D x 89”H
*Usable Interior Volume: 408 cu.ft.
*Internal Height: 89” (from floor to bottom of fan guard)
*Growth Area: 96 sq.ft. (provided on twelve adjustable shelves [three tiers])
*Shelving: The chamber is supplied with three tiers of vertically adjustable shelving in 1” increments consisting of four standalone mobile with wheels Metro shelving units. Each shelving unit consists of three shelves each 24”W x 48”L with four posts and four caster similar to Metro item 5MPBXGSA. Each shelf is electro-zinc plated with a single-dip chromate post treatment after welding. Surfaces additionally protected against rusting with a hard baked plastic resin coating after plating. This Metroseal 3 finish is enhanced with built-in Microban antimicrobial product protection, which protects the Metroseal 3 coating from bacteria, mold, mildew and fungi that cause odors, stains and product degradation.
*Growth Height: Adjustable up to 24” per tier when using three tiers of shelving without casters
*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 door is a flush type for a 36” 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 sills are made of 18-gauge stainless steel attached to an aluminum base plate and covered with anti-skid strips. Door jambs are made of fiberglass reinforced plastic.
*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: Chamber is erected on existing building floor by means of coved vinyl screeds which are lagged to existing floor for rigidity (the wall panels sit inside these vinyl screeds which act as an insulator between the cement floor and the wall panels)
*Instrument Ports: Two 1” diameter ports provided through front wall
*Control Cabinet: Controller shall be mounted at eye level (a clear plexiglass cover shall protect controls from damage and shall be furnished with lock and two keys)
LIGHTING
*Light Intensity: Up to 300 micromoles/m2/sec at 6” from lamps
*Lamps: Balance spectrum for plant growth using T-8 fluorescent lamps plus extended life tungsten incandescent lamps
*Programming and Control: Photoperiod is programmable via real time controller (three programmable levels of lighting)
*Light Fixtures: There are twelve light fixtures per chamber (three tiers). Each fixture is removable and individually adjustable.
