Floor ModelAssociated 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.

Standard features on AES Chambers, including CO2/LN2 Chambers:

 

·         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 fully-welded construction.

·         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 temperatures.

·         Door latches have a quick-action cam mechanism for positive closure.

·         High density low “K” factor, non-settling fiberglass insulation is standard in walls and doors.

 

 

 

Thermal Shock ChamberThermal 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.

 

 

 

 

Associated Environmental Systems offers Thermal Shock Chambers that support true thermal shock testing.

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.

Salt Spray / Fog ChamberCorrosive atmosphere chambers subject test items to corrosion without introducing other contaminants into the test area.

 

Associated 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 corrosion.

·         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 area.

·         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 system.

 

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).
