Solid Construction Walk-In Temperature/Humidity Chambers, W-SERIES
Russells unitized solid construction test chambers give the   
maximum durability and performance for your most demanding
test requirements.  Moisture build up can be very damaging to
many products, especially electronics, causing corrosion and
oxidation.  Russells W-Series chambers allow manufacturers to
simulate how their products will perform in the most extreme
temperature and humidity conditions.
Russells W-Series chambers can provide the following
combination of controlled testing environments:
•    Steady state temperature and temperature/humidity tests
•    Rapid rate temp./humidity cycling tests (>9˚F/5˚C/min.)
•    Elevated temperature heat aging (>350˚F/177˚C)        
Cabinet Features:
•    Brushed 304 stainless steel liner, heliarc welded and
dye checked
•    Welded steel frame, removable access panels to
serviceable components, durable enamel finish
•    Fiberglass insulation, 0.25K factor
•    Full opening door with dual gaskets (many door
configurations available)
•   Temperature range for single stage refrigeration:
-13˚F/-25˚C to 350˚F/177˚C
•    Temperature range for cascade refrigeration:
-100˚F/-73˚C to 350˚F/177˚C
•    Humidity Range: 10% to 95% RH within the bounds
of a 185°F/85°C max. dry bulb and a 40°F/4°C min.
Russells W-Series chambers are available in sizes from 225 cu./ft. (6,371L) to drive in sizes. A Russells
application engineer can assist you in selecting the chamber configuration and size that is most
economical for your testing needs.   Let Russells give you the competitive edge!  Call 386-801-4290
