The GR series of walk-in rooms feature high intensity, energy efficient LED lights and a downward airflow design that is redirected up through the plants.

Lighting

• The standard package for the GR consists of energy saving LEDs that provide a broad-based light spectrum. The fixed lamp canopy delivers light intensity of 1,200 µmol/m²/s measured at 39” (1 m). Full intensity control is available at the user interface with light output measured by a full-spectrum Apogee Quantum light sensor that automatically adjusts depending on user requirements.

Airflow

• The airflow design directs air downward along the center aisle way. Air is then redirected returning upward between the plants and through the lamp canopies. Filtered and adjustable fresh air intake enables researchers to exchange air to the chamber in a controlled manner.

Refrigeration

• Cooling for the GR series is provided by a self-contained water-cooled condensing unit with hot gas bypass for continuous compressor operation. An electronic modulating valve provides tight temperature control while ensuring quiet operation. Pressure transducers are included for monitoring the status of the refrigeration system. Alternative refrigeration methods are available depending on site-specific and/or user-defined requirements. Consult the factory for heat rejection information and other refrigeration options.

Experiment Protection

• User programmable “set and forget” alarms track actual vs. user-defined setpoints. This allows for exceptionally accurate monitoring without the need for adjustment every time the set point is redefined. Backup “high/low” alarms provide further protection while visual and audible notification is provided when any alarm is activated. Contacts for connection to a building management system are also included.
