The PGW40 equips the researcher with a walk-in environment accessible from two large doors on the front of the chamber.

Lighting

• The standard lighting for the PGW40 consists of energy savingLEDs that provide a broad-based light spectrum. The fixedlamp canopy delivers light intensity of 1,000 μmol/m²/smeasured at 39" (1 m). Full intensity control is available at theuser interface with light output measured by a full-spectrumApogee Quantum light sensor that automatically adjustsdepending on user requirements.

Airflow

• Airflow for the PGW40 is distributed uniformly upward usingConviron's innovative Unifloor® air distribution plenum. The unitincludes fresh air intake and exhaust ports which are adjustableto allow up to 55 ft³/min (1.55m³/min.) of air exchange.

Refrigeration

• Cooling for the PGW40 is provided by a self-contained watercooled condensing unit with hot gas bypass for continuouscompressor operation. An electronic modulating valve providestight temperature control while ensuring quiet operation.Pressure transducers are included for monitoring the statusof the refrigeration system. Alternative refrigeration methodsare available depending on site-specific and/or user-definedrequirements. Consult the factory for heat rejection informationand other refrigeration options.

Control and Monitoring

• The PGW40 comes equipped with Conviron's most advancedcontroller - the CMP6060. User programmable "set and forget"alarms track the chamber's operation versus user-defined setpoints. This allows for exceptionally accurate monitoring withoutthe need for adjustment every time the set point is redefined.Backup "high/low" alarms provide a further level of protectionwhile visual and audible notification is provided when any alarmis activated. Contacts for connection to a building managementsystem are also included.
