PGW40

Product catalog summary

Product Overview/Applications
The PGW40 is a walk-in plant growth chamber designed for research involving taller plants. It features two large front doors for easy access and supports plant growth to full maturity under moderate to high light conditions. The chamber offers low-temperature options for operation below 4°C and a defrost option to prevent temperature rise during defrost cycles.

Lighting
The PGW40 uses a combination of fluorescent and halogen incandescent lamps to provide a suitable light spectrum for plant growth. The lighting system allows for programmable lamp groups and adjustable light intensity through Conviron’s LightrightTM canopy.

Airflow
Airflow is uniformly distributed upward using Conviron’s Unifloor® air distribution system. The chamber includes adjustable fresh air intake and exhaust ports, allowing up to 55 ft³/min of air exchange.

Refrigeration
The chamber is cooled by a self-contained water-cooled condensing unit with hot gas bypass for continuous operation. An electronic modulating valve ensures precise temperature control and quiet operation. Alternative refrigeration methods are available based on specific requirements.

Experiment Protection
User-programmable alarms monitor chamber operation against set points, providing accurate monitoring without frequent adjustments. Backup alarms and notifications are included for additional protection, and connections to a building management system are available.
