Envirotherm Temperature and Humidity Cabinet TEC

  • Product Testing and Quality Control
  • Research and Development
  • Industrial and Manufacturing Processes

The TEC Envirotherm Cabinet series, manufactured by Thermoline, offer accurate and precise temperature and humidity control. These high-performance models can perform heating, cooling, humidification and dehumidification functions. The range is available in two standard capacities, 460L and the double door 850L.

Looking the part, our Envirotherm cabinets are constructed from stylish Colorbond steel – with marine grade 316 stainless steel doors and interior.

Which cabinet is right for me?


With the ability to produce similar climate conditions to specimens’ native environments, it’s only natural that you’d choose our Envirotherm cabinets to store your samples.

Robust and reliable, our cabinets’ refrigeration systems can simulate temperatures from -35°C to +120°C with a 30–95% relative humidity range. Not to mention the 600-watts-worth of heat removal capacity.

Whether you’re material testing or climate testing, you’ll be comforted by the knowledge that your equipment is keeping your samples safe.

Even if you need to open the door, the cabinet’s fast recovery time will limit any temperature fluctuations – maintaining uniform conditions throughout the chamber enclosure. With a constant airflow within, conditions remain uniform throughout the enclosure, and alarms will alert if deviations from any setpoints occur.

Powered by our STAR X touchscreen control system, you can easily and precisely control the cabinet’s temperature, humidity and optional carbon dioxide. The STAR X allows for the operator to synchronise programmed settings to real time and has an ethernet connectivity which, once connected, will allow the operator to perform all functions via a PC. The STAR X logs the performance of the cabinet to onboard memory. This memory can hold up to 365 days of logged data and for ease of use,  we have incorporated a live trend screen to allow the operator to quickly check the performance conditions within the cabinet. Alternatively, the operator can download the logged data to a USB flash drive for archiving or review via a PC. No specific software is required to view logged data. A simple spreadsheet program is sufficient (Microsoft Excel or similar).

Australian Made, our cabinets are available in single door 460L and the double door 850L capacity – so you can choose the size that suits your samples.

Support & FAQs

At Thermoline, we strive to supply helpful customer support to ensure that you get the most out of our products. We are committed to providing whatever support our customers need, wherever they are in the world. If you can't find your solution in the below FAQs or Knowledge Base, please contact our friendly support team.

What is an environmental chamber used for?
A temperature and humidity test chamber is suitable for testing your products, where they must withstand various temperatures during manufacturing, transport, storage and use. The environmental chamber allows the conditioning of test samples to a specific temperature and relative humidity conditions.
How do you maintain humidity in a chamber?
A refrigeration system is ideal for doing this. The evaporator coil in the chamber attracts moisture in the air, causing it to condense into water, which can then be drained away. A refrigeration system will help control temperature and humidity. Also, note that humidity is always relative to temperature; therefore, to be able to control humidity accurately and precisely, you need to control the temperature as well.
Can I store a series of environmental chambers adjacent to one another?
Yes, absolutely. You'll need to have enough space between cabinets to ensure that the exhaust from one does not blow into the next cabinet causing a reduction in performance. If space is an issue, please contact us about our innovative deflectors that allow chambers to be installed in close proximity to one another
What is a temperature and humidity cabinet?

The purpose of the TRH temperature and humidity cabinet is to simulate and test the effects of various environmental conditions on products, materials, or samples in a controlled and repeatable manner.

These chambers are typically used in research and development, quality control, and manufacturing processes across a variety of industries such as electronics, automotive, aerospace, and pharmaceuticals.

What is Dew Point?

The dew point is the temperature at which dew (condensation) forms and is a measure of atmospheric moisture. It is the temperature to which air must be cooled at constant pressure and water content to reach saturation. Dew points are expressed as a temperature. Higher dew points correlate to higher moisture content, also known as absolute humidity.

The dew point represents the lowest temperature to which air with specific temperature and relative humidity (RH) can be cooled. At the dew point, air has a relative humidity of 100%, and additional cooling produces condensation rather than lowering the air temperature.

Do I need a water tank to supply water to the cabinet?
You only need a 25L/55L water tank if your cabinet cannot be connected to mains water supply. If mains water supply is not possible, 25L gravity and 55L pump water feed tanks are available to supply water to the cabinet. As a rule of thumb, a cabinet running at 90%RH will deplete a 55L water tank in approximately three days.
