Environmental test chambers for nearly every industry

Associated Environmental Systems was founded in 1959 in Wayne, New Jersey, with the goal of making sophisticated test chambers capable of meeting the most demanding testing requirements.

Since then, AES has become an innovative industry leader with divisions on the East Coast, West Coast, and Midwest. We’re proud to distribute environmental chambers globally and across nearly every commercial industry. 


The AES Way

We design, manufacture, support, and service robust environmental chambers and battery testing fixtures you can rely on. 

From humidity and temperature chambers to salt spray and thermal shock chambers, the world’s top companies depend on us for their testing solutions. We have the ability to optimize the type of testing that works specifically for your situation, including small benchtop chambers to very large walk-in units, saving you substantial time and money.

Patented Battery Testing Fixtures

Batteries power our most-beloved devices, but these technologies wouldn’t be possible without innovations in battery testing, such as our patented battery fixtures. ATPFLEX, ATPHEAVY, and ATPHEAVY Adaptable can accommodate an extensive assortment of battery shapes and types. We offer battery testing solutions for almost any situation.

Our Values

Technicians working on a chamber

1. Design

Our team of skilled SolidWorks and AutoCAD design engineers create 3D renderings and ensure your specifications are met before manufacturing begins. Our detailed schematics guarantee each component looks and operates as it should.

2. Efficiency

Our turnaround times are rapid. In addition to keeping standard chambers in stock, our custom environmental chambers are built using computer-guided lasers with unparalleled precision and welding expertise, reducing lead time.

3. Dependability

That AES logo on your chamber lets you know our entire team is behind you. Over-the-phone testing consultation, in-person maintenance, or on-site repairs, we’re there for you. We’ll even order the spare parts you need and install them for you.
