Reliable Temperature & Humidity Systems

  • Heating System

    Fast response electric heaters deliver uniform temperatures up to 180°C (365°F) with precision of ±.0.5°C. 

  • Cooling Options

    AES Chambers consists of a self-contained mechanical refrigeration system with a single-stage or cascade configuration. Air or water cooled systems, with optional LN2/CO2 boost for rapid pulldown. Even without boost cooling, AES standard cascade refrigeration systems have the fastest standard change rates of any environmental test chamber manufacturer.

  • Air Circulation

    Proprietary fan and baffle design to ensure consistent chamber conditions

  • Humidity System

    AES uses vapor generator systems to give you precise control over the humidity conditions of your chambers’ internal workspaces. The vapor generator system is a closed stainless steel or copper tube. An element heats a constant water source creating vapor or steam that travels through the tube and mixes with conditioned air in a plenum before moving into the workspace. Notably, this water source must be treated and demineralized to avoid contaminating the tes

  • Optional Features to Increase Humidity Range

    High Humidity Sensors let you measure humidity as high as 98% RH.

    Dry Air Purge Through Desiccant Air Dryers can achieve humidity as low as 5% RH. It compresses air through a desiccant system, absorbing the moisture before it moves into the workspace.

    Dry Nitrogen Purges prevent condensation and frost from accumulating on DUT surfaces at colder temperatures by forcing out the moisture-heavy air. This also prevents the oxidation of metals at high temperatures.

    Recirculating Desiccant Air Dryers are a more feasible option for larger chambers. Air is circulated through a desiccant system and then returned to the chamber, often cycled through a honeycomb wheel that releases captured moisture into the external workspace.

    Associated Environmental Systems has developed a Dew Point Calculator to help you determine whether you'll need optional features for your humidity systems.

Frequently Asked Questions

Have Question? We are here to help

What is a humidity chamber

A humidity chamber is a controlled testing environment that regulates both temperature and moisture levels. It allows engineers to replicate real-world conditions and study how products respond to changes in heat and humidity.

How does a humidity chamber work?

Leading test chamber manufacturers build humidity chambers with closed vapor generator systems. They require properly conditioned water as well as regular maintenance to ensure performance. Read more on How Humidity Chambers Work.

How accurate are AES humidity chambers?

All AES humidity chambers hold precision of about ±0.5 °C for temperature and ±2–3% relative humidity. This level of testing accuracy ensures repeatable results for product validation, compliance, and long-term reliability studies.

What is the temperature range of a humidity chamber?

Standard humidity chambers operate from –37 °C to +180 °C (–34.6 °F to 356 °F), with extended models reaching as low as –70 °C (–94 °F). Within this range, chambers maintain stable conditions to support diverse testing requirements.

What are the main functions of a humidity chamber?

Humidity chambers rely on vapor generator systems to create specified conditions in the workspace. Companies across industries (from packaging to electronics, pharma, communications, and more) test their products in humidity to evaluate the effectiveness of those products in different environmental conditions and set expectations for consumers. Read more on Test Chamber Functions.

What kind of water should I be using in an AES humidity chamber?

AES suggests defined ranges for resistivity of (0.05MΩ * cm to 6MΩ * cm, conductivity, 20µS to 0.167µS TDS: 10 ppm to 1 ppm, and total dissolved solids (TDS) (10 ppm to 1 ppm). The demineralizing cartridges used to condition the water should be checked monthly.

Properly caring for your environmental test chambers expands your chambers lifespan for more that 10 years. 

Humidity chambers: Calculating the dew point to fit your testing

The relationship between temperature, relative humidity, and dew point can be a bit complicated to calculate, but it’s vital for ensuring reliable and consistent humidity testing. Read more on Calculating Dew Point.
