INTRODUCTION
The CARON 6010 & 6030 series Environmental Test Chambers provide multiple capabilities to
create repeatable environmental conditions for numerous applications including:
•
Product shelf life
•
Stability and package testing
•
Light exposure and temperature evaluation studies
•
Electronic component burn-in
•
TAPPI testing
•
Photostability
•
Plant growth
•
Insect rearing
These chambers utilize environmentally friendly HFC refrigerant and CFC-Free insulation, and is
designed to meet NEC, UL and CSA standards for safety and performance.
Controlling the chamber temperature requires the ability to heat and cool. Heating of the chamber
is achieved by duct heaters, and cooling is achieved by a direct expansion/vapor compression
refrigeration heat exchanger mounted in the duct, combined with horizontal airflow pattern which
creates better air uniformity, and temperature control.
A bi-modal controller (single input - dual output) is necessary for proper control of the system that
can drive the process variable in either direction. The refrigeration system uses a single
condensing unit that will allow independent cooling and dehumidification. This insures continuous,
safe and reliable operation of the compressor even when no cooling is required. This also
prevents the compressor from rapid cycling “on” and “off” which shortens the compressor life.
