Plant Growth Chamber – PG034

Insulation
  • Entire cabinet structure and doors insulated using foamed-in-place CFC-free polyurethane foam.
Refrigeration System
  • 3 year warranty on compressor. Compressor designed to be “Plug and Play” for ease of repair.
  • Unsurpassed temperature control through continuous refrigeration bypass system.
  • Refrigeration system factory balanced using CFC free 134A refrigerant.
  • Top mounted condensing unit.
  • Factory pre-engineered capillary tube system with oversized condenser and evaporator to reduce product pull down time and to consistently maintain interior cabinet temperature (non-adjustable capillary tube system superior to problematic expansion valve).
  • Evaporator – epoxy-coated at the time of manufacture to eliminate the potential of corrosion
  • Varying heat removal options exist – remote condensors, water cooled, etc.

Features

PG Series

The PG series chambers feature hot gas by-pass technology which controls the temperature of the epoxy coated evaporator for greater uniformity. Compressors in our PG series of environmental chambers come with a three year warranty - which is the longest in the industry.

Superior Control and Uniformity

The ultrasonic humidification system provides excellent humidity control and avoids hot spots seen during chamber mapping of steam boiler equipped chambers. Standard control at the sensor in these chambers is ±0.2°C and ±0.3%RH.

Widely Proven, Non-Proprietary Controllers

Standard controllers for the PG Series are manufactured by Fuji Electric and are ideal for chambers. Unlike many proprietary controllers, this controller is commercially available and proven in tens of thousands of installations. Standard functions include: autotuning, fuzzy logic, PID control, programmable alarms, calibration capability, offset capability, etc. A touchscreen control interface is optional. Other controller manufacturers are also supported (Watlow, Allen Bradley etc.)

Greatly Reduced Direct and Indirect Energy Loads

The PG Series chambers utilizes less energy than comparable chambers and introduce less impact upon building cooling systems. This efficiency “dual benefit” allows our chambers to be located in spaces unsuitable for other chambers. Electrical energy savings by the PG series vs. steam boiler equipped chambers can easily amount to hundreds or thousands of dollars saved per year.

Services and Warranties

We offer free technical support throughout the lifetime of your chamber. In addition to standard warranties, we also offer extended warranties for cooling components, parts and labor. We also provide preventive maintenance services at an additional cost. Please ask for a quote.

Quiet Operation

The PG chambers utilize quiet and highly efficient DC fans. Locating these chambers in laboratory workspaces is a viable option.
