WRH-STRUCTURAL

FloorWalk-In

Solid-structure walk-in models are built using AES' high-performance versions of the popular floor-style models and can be ordered for stability testing purposes or cycle testing.

STRUCTURE.  When you require extreme temperatures and saturated humidity rates, your testing is more suited to structural build construction.  Structural walk-in rooms are welded, one-piece units assembled with durable steel making them optimal for heavy or over-sized product loading and high humidity. Structural walk-in rooms are advantageous for speedy temperature change rates, high humidity, and explosion resistant applications.

In high-humidity conditions where increased pressure is present, a welded-steel structural frame interior is required.  Under these reinforced conditions, temperatures from -65°C to +150°C (-85°F to +302°F) can be sustained. And relative humidity can range from 10-95%.  

Structural build chambers are most often custom-designed products. Because of our extensive product offering and years of designing test chambers, your specific needs will not increase delivery time, but they do require more planning and engineering design time to create the plans and drawings which are followed by customer approvals before manufacturing can begin.

PERFORMANCE.  To optimize temperature conditions within the workspace a specially designed plenum allows airflow to enter the space from the back and pushed to the sides for conditioning. Toward the front of the workspace, registers spread the air top to bottom creating a uniform workspace for testing dense products under dead-load and live-load situations. 

Airflow for products under test is fed by triple-blower wheels at the back wall with left and right air discharge.  Plenums on both the left and right sides condition and discharge air to the front of the workspace through baffles that direct the airflow uniformly top to bottom.  As air enters through the back of the chamber, the flow is directed along the sides through a plenum where the air is conditioned to the correct temperature.  When the air reaches the front of the chamber it flows through registers with baffles that direct the air to move uniformly from top to bottom. Stacked circulation fans on the back wall of the workspace pulls the air through the product and back into the plenum to be reconditioned.  

Access ports can be placed on each side, using your specific requirements. 

HEATING SYSTEM.  A mix of several open nichrome heaters and ceramic core nichrome heaters spread across airflow for reliable and accurate temperature control within ±0.5°C.

HUMIDITY SYSTEM.  Reach highly saturated humidity levels with no concerns. High-pressure environments require solid structures so there is no chance of leakage through seams. To extend your humidity range, see the optional features section. View RH Chart.   

COOLING SYSTEM.  The cooling system is a self-contained mechanical refrigeration system with the configuration that will fit your needs. An AES engineer can discuss the benefits of a water-cooled or air-cooled condenser. 

Add boost cooling with liquid LN2 or CO2 for even faster pull-down rates. It's a great option for stress tests that require rapid cooling.  Even without boost cooling, AES’ standard cascade refrigeration systems have the fastest standard change rates of any environmental test chamber manufacturer. See Basic Specifications tab below. 

INSTRUMENTATION.   Walk in Series Test Chambers have incorporated the AESONE CONNECT® creating a robust connected device for a standard and uniform interface making operation easier.
