WRH-PERFORMANCE CYCLING

FloorWalk-In

Performance cycle test chambers can come in many shapes and forms. With panel or solid-structure construction the extent of your test parameters will drive your decision to choose one or the other.

STRUCTURE.  You gain most flexibility with self-supported, panel-construction, walk-in chambers as they allow for free-standing, self-supporting units that are cost-effective and efficient. Panelized construction allows the installation to fit through most doorways as it is assembled on-site.  Panel thickness, flooring, and door size are interchangeable to meet your environmental testing needs; and there are several options that allow you to get the ports and viewing-windows, and accessibility you are looking for.

Likewise, AES' long experience with structural test chambers allows you to build what you need based on an existing design model or our engineering team can work with you to create a new performance workspace design combination that will meet all your needs. 

PERFORMANCE.  To optimize temperature conditions within the workspace, specially designed plenums are designed so air is conditioned immediately within the workspace or in a separate plenum depending on how your product fits into the test chamber workspace. 

Airflow for products under test is fed by stainless steel blower wheels at the back wall or from the top, specially designed baffles discharge conditioned air in the direction that most thoroughly conditions all of the air around your product at the same rate. As air enters workspace intake fans directing the flow through a plenum area where the air is conditioned to the correct temperature. Before the air reaches the product it flows through registers with baffles that direct the air to move uniformly around your product. 

Access ports can be placed where you need them along the walls. Most commonly are placed on the left and right side walls and are centered front to back and spread equidistance top to bottom. Viewing windows are commonly placed on the door and additional windows can be placed on the side walls. 

HEATING SYSTEM.  Walk-in chambers are equipped with a combination of ceramic-core and nichrome rod heaters spread across plenum for reliable and accurate temperature control within ±0.5°C.

HUMIDITY SYSTEM.  The humidity system has a standard range between 10% and 95%. To extend your humidity range, see the optional features section. View RH Chart.   

COOLING SYSTEM.  The cooling system consists of a self-contained mechanical refrigeration system with a single-stage or cascade configuration, using an air-cooled or water-cooled condenser depending on your test needs and incorporating your facility restrictions. 

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.

INSTRUMENTATION.  All walk-in test chambers have incorporated AESONE CONNECT creating a robust connected device for a standard and uniform interface making monitoring and operating your test chamber easier.
