Safety Measures

We offer multiple types of safeties on our test chambers to help protect your product and your test chamber if anything malfunctions.

Heat Fuse: (Standard)

A heat fuse or thermal fuse, will interrupt the flow of electricity to the test chamber and shut it down if it reaches a certain temperature.

High Temperature Safety: (Standard)

A digital set temperature safety that will shut down the test chamber if it goes over a certain temperature.

High/Low Temperature Safety:

A digital set temperature safety that will shut down the test chamber if it goes over a certain temperature or below a certain temperature.


Optional Features:

  • Shelf Modification (placement, size, number)
  • Custom Porting Sizes
  • Dry Nitrogen Purge
  • LN2 Cooling
  • CO2 Cooling
  • Heater for Window
  • Optional Window Sizes
  • Desiccant Air Dryer
  • Floor Stand w/ Casters
  • Additional Blank Door
ramp rate performance testing by associated environmental systems


Customers require the ability to reliably test as much product as possible in as little time as possible. AES standard cascade refrigeration systems have the fastest standard change rates of any environmental test chamber manufacturer, with average pull down times of 2.5°C/ minute and average ramp rates of 4.4°C/ minute. AES chambers allow you to maximize product testing efficiency without sacrificing quality.

mike designing chambers by associated environmental systems


All test chambers incorporate non-magnetic welded type 304 stainless steel inner chambers, a cold-rolled steel, powder coated exterior, efficient low "K" factor thermal insulation and direct drive-shaft powered forced air circulation along with open wire nichrome resistance elements generating ultimate functionality while maintaining a pleasant laboratory appearance. State-of-the-art regulation techniques result in high accuracy and long term stability.


Heating System

AES heating systems are all-electric and pass air over fast-response low watt density resistance heaters with a ceramic core insuring a long reliable life with no down time. The combination of airflow, instrument response and these fast reacting heaters give very accurate and straight-line control of temperatures. Our heating systems support temperatures upwards of 180°C (356°F) and heaters may be controlled independently or in unison. Heating systems are located in a plenum so that test items are not subject to direct radiation.

Liquid Cooling

Liquid Cooling (Option)

Water is recommended for larger refrigeration systems or systems that support low to freezing temperatures as water is a thicker medium that air and more efficient with heat transfer. Liquid cooling with CO2 or LN2 is different than a CO2 or LN2 boost in that the liquid cooling systems control the refrigeration with a designated percentage of the system's total power, depending on the cooling demand. Boosts do not offer precise cooling control and instead act through a direct and immediate effect.

Liquid CO2 Boost

Liquid LN2 or COBoost

Via an endothermic process, directly injected liquid carbon dioxide instantly drops the temperature of the test chamber interior, ideal for stress tests and efficient thermal dissipation. CO2 can lower the chamber's internal temperature almost instantaneously to -73°C (-100°F). Liquid CO2 is available to customers in either a bulk system stand-alone tank, or a cylindrical system which stores much smaller amounts in multiple attached vessels.

Liquid nitrogen is directly injected into the test chamber to both expand achievable temperature ranges and raise the temperature change rate. Upon contact with the air inside the test chamber, following the same thermodynamic principle as the CO2 boost, liquid nitrogen can rapidly decrease the interior chamber temperature. Liquid N2 boost can quickly lower the temperature to a cryogenic temperature of -185°C (-300°F).




Unlike CO2 which has a boiling point of -57°C (-70.6°F), liquid nitrogen has a boiling point of -196°C (-320.8°F), therefore have pull-down rates that are much faster.

LN2 or CO2 cooling option for the FDP-4246 should only be considered in bulk form.  Cylinder option for the sizable workspace is not ideal.



CO2 Scrubber Cartridge

A dependable filtering system designed to eliminate contamination caused by moisture, oil and dirt in bulk or bottled liquid CO2 supplies. Suitable for both 1000 psi and 300 psi service and assure pure CO2 at valves and metering orifices, completely eliminating problems of clogging and erratic operation.

Manifold for 6 Cylinders (MLC-6)

Included with the cylinder based CO2 cooling system, the manifold system is designed to regulate and monitor the vaporized gas coming from cryogenic cylinders. This system may be used to test to the MLC-6 specification.

CO2 Tank to Test Chamber Hose (DAK-6)

Included with the bulk order CO2 cooling system, the tank to test chamber hose provides safe and effective delivery of liquid CO2 to the chamber interior. This system may be used to test to the DAK-6 specification.


Bulk System

  • -18°C (0°F) and 300 psi
  • This larger reserve system has a higher initial cost but then offers a much lower per pound CO2 cost to customers and is recommended for long duration testing or multi-chamber operation.
Control and Data Collection

Control and Data Collection

Digital chart recorders allow users to escape the limitations of pen and paper data recorders and provide a way to instantly monitor and store valuable testing data.

We offer a variety of controller and data logging options to fit your needs
