MBDW80

Product catalog summary
Product Overview and Applications
The MBDW series walk-in chamber is designed for research on C4 high-light plants. It features a modular platform with a top-down airflow pattern for consistent plant canopy temperatures and spectral aluminum interior walls for light uniformity. A separate cooling system addresses heat from the lighting system.
Lighting
The standard lighting package includes metal halide and tungsten incandescent lamps for a broad light spectrum, with optional packages for higher intensities and programmable control.
Airflow
The chamber employs a top-down airflow pattern with independent ventilation and conditioning systems. Pressure transducers monitor the refrigeration system, with alternative methods available based on specific needs.
Experiment Protection
User-programmable alarms monitor chamber operation, with backup alarms for additional protection. Visual and audible notifications are provided for alarm activation.
Key Product Attributes
  • High light availability and uniformity
  • Discrete lamp loft reduces heat transfer
  • Top-down airflow for uniform temperatures
  • Extended height for large plant growth
  • Modular design for larger sizes
  • CE certified
Refrigeration
The chamber features a water-cooled condensing unit with hot gas bypass for continuous operation. An electronic modulating valve ensures tight temperature control.
Performance Data
Temperature range is -2°C to +40°C with lights off and +5°C to +45°C with lights on. The chamber offers various sizes with different growth areas and capacities.
Control System
A 7” Meditech touch screen controller is used for operation.
Construction
The chamber is constructed with galvanized steel and polyurethane insulation. It includes a safety release latch door, observation window, and instrument ports.
Lighting
Lighting intensity is 1,100 micromoles/m²/s, with independent programming for each lamp type. Lamps are separated from the growth area by a transparent barrier.
Temperature Control
Temperature range is +4°C to +40°C with lights off and 10°C to 40°C with lights on. Safety limits include programmable alarms and independent factory-set limits.
Cooling System
The system includes a water-cooled condensing unit with electronic modulating valve and CFC-free refrigerant.
Air Flow
Features vertical airflow from perforated diffusers and filtered fresh air inlet.
Optional Accessories
  • UPS for uninterrupted power supply
  • High intensity discharge lighting
  • Humidity and CO2 control options
  • Growth height extensions
  • Right-hand control panel
  • Refrigeration options for lamp loft cooling
Specifications
The document outlines specifications for glycol heating/cooling systems designed to work with central chiller refrigeration systems, including proportional valve control. It also describes floor-mounted units for situations where ceiling space is limited, with specific requirements for refrigeration and electrical interconnections.
Essential Spare Parts
Consultation with the factory is recommended for essential spare parts and spare lighting sets.
Plant Growth Room - MBDW Series
The document details the differences between the MBDW series chambers, specifically the MBDW80 and MBDW120 models.
  • MBDW80: Exterior dimensions are 10’0”W x 11’1.25”D x 9’6.25”H, with an interior growth area of 80.9ft² and a growth capacity of 640ft³. Fresh air is filtered at 100 cfm.
  • MBDW120: Exterior dimensions are 10’0”W x 16’4.5”D x 9’6.25”H, with an interior growth area of 121.7ft² and a growth capacity of 964ft³. Fresh air is filtered at 150 cfm.
Notes
Standard refrigeration systems are water-cooled with specific connection requirements. The document specifies that the depth dimension is for chamber size only and does not include the door latch. There are tolerances for length, width, and height dimensions.

MBDW80-2

Plant Growth Room MBDW Walk In Room Product Overview/Applications The MBDW series walk-in chamber is based on a modular platform available in increments of 40ft2 (3.7m2). These units offer a precise chamber environment typical of research involving C4 high-light plants grown to maturity. Unique is the top-down airflow pattern which ensures consistent plant canopy temperatures throughout the chamber. Spectral aluminum on the interior walls produces unparalleled light uniformity, while the discreet lamp loft area uses a separate cooling system to mitigate heat produced by the lighting system. control...
