Associated Environmental Systems supplies
Temperature/Humidity Chambers to program controlled conditions of combined
temperature and relative humidity.
All chamber components
offer maximum resistance to the corrosive effects of moisture combined with
extreme conditions. Consult the AES design engineering services for special
temperature and humidity conditions.
BHD-500 and BHD-200 Series
The BHD-500 Series use
a single-stage mechanical refrigeration system that can produce dry bulb
temperatures down to 35°F/-37°C.
The BHD-200 Series
produces dry-bulb temperatures down to -100°F/-73°C.
Rapid response heaters are baffled to eliminate direct
radiation to the test items at high temperatures of up to +350°F/+177°C.
Chamber liners are hermetically sealed and made of heliarc
welded stainless steel.
Self-contained systems use a two-channel microprocessor digital
Easy to operate.
Standard units are available from stock in three (3) sizes: 1.5
cubic feet, 5.8 cubic feet, and 10 cubic feet.
Temperature range is 0°C to +94°C with an optional temperature
range of -20°C to +94°C.
Humidity range is 20% to 98% 2 RH.

Standard features on AES Chambers, including
Forced air circulation systems maintain precise temperatures and
use a fan powered by a direct drive, heavy duty electrical motor that is
externally mounted with an integral stainless steel shaft.
Heating systems are located in a plenum so that test items are
not subject to direct radiation. Open wire nichrome resistance elements combine
maximum heat transfer with rapid response time and long operating life.
Fail-safe high-temperature control guards against damage due to
abnormal high temperature extremes.
Fusible thermal links guard against temperatures exceeding the
upper design limits of the equipment.
Non-magnetic welded type 304 stainless steel inner chambers.
Exterior cabinet of reinforced cold rolled steel with
Textured enamel finish for a laboratory look.
Most doors are combination hinged and removable for easy access
access and modification.
Doors are gasketed with silicone to handle the expanded range of

High density low “K” factor, non-settling fiberglass insulation
is standard in walls and doors.
Thermal Shock Chambers make it possible to
automatically and repeatedly transfer a test item from a hot environment to a
cold environment or from a cold environment to a hot environment. This process
is defined as true thermal shock and it is different from thermal cycling,
where the specimen is introduced into the chamber and the chamber temperature
is then cycled. A true thermal shock chamber can achieve a 265°C temperature
variation rapidly, while thermal cycling may take hours to ramp up or down.
Environmental Systems offers Thermal Shock Chambers that support true thermal
Two Station Chambers
Two Station Chambers provide an upper compartment for a heated
environment and a lower compartment for a cold environment.
Three Station Chambers
Three Station Chambers contain an additional middle compartment that
is exposed to room ambient (ambient dwell) and is enclosed with expanded metal.
Each chamber contains
a specimen holding basket (transport carriage) pneumatically operated from a
compressed air source.
Corrosive atmosphere chambers subject test items to corrosion
without introducing other contaminants into the test area.
Environmental Systems' salt spray chambers are entirely self-contained. The
basic chamber conforms to military specifications, including MIL-STD-810, and
is also used for many commercial and ASTM specifications.
The MX-9200 corrosive atmosphere chamber:
Has a transparent Lucite test area that is impervious to
Provides continuous direct visual observation of the test item.
Contains thermostats and metallic items made of Monel to avoid
transference and minimize corrosion.
Provides lucite rods to hang or support items within the test
Performscontinuous unattended tests for up to 72 hours. This
period may be extended by adding an external storage tank, a tower level
control and a salt solution reservoir level control to automatically refill the
A high reliability
thermostatic temperature controller maintains the salt solution at a preset
controlled temperature in a reservoir within the double wall construction. The
salt solution is introduced into the chamber through an atomizing nozzle. The
nozzle can be calibrated by AES to perform to MIL-STD-19500B, paragraph 40.8
and other specifications. This specification requires that a salt residue be
deposited on the specimens, in addition to generating salt fog atmosphere.
The preparation of a
salt solution consists normally of sodium chloride containing as a dry compound
not more than 0.1% of sodium iodide and not more than 0.2% of total impurities.
This solution is prepared by dissolving five parts by weight of salt in 95
parts by weight of distilled water. It is important to maintain this solution
at a specific gravity of from 1.023 to 1.037. The solution is maintained at a
controlled temperature of 95°F by the chamber's own integral temperature
control system (temperature is adjustable).
