Walk-In Chamber

Do you have something big you need to test?

A Thermotron Walk-In Chamber serves as a test site for large components, assemblies, and finished products. Thermotron manufactures both Panel Walk-In Chambers and Solid Walk-In Chambers and can be configured as a temperature chamber or a temperature-humidity chamber.

A Panel Walk-In Chamber is made from lightweight insulated panels for fast and easy installation. Outside banding helps prevent leaking and keeps moisture out of the chamber and workspace temperatures steady.

Our Solid Walk-In Chambers are custom built to accommodate almost any size. They feature welded walls, creating an environmental room for applications requiring controlled temperature and humidity testing exceeding 85°C. Typically, for ease of installation, a Solid Walk-In Chamber works best in new construction buildings, areas with extremely large doors, or rooms where outside walls can be easily removed.

Below are some standard Panel Walk-In Chamber sizes; however, custom sizes are available.

8800 Chamber Data Acquisition (DAQ)

Thermotron’s streamlined data acquisition system (DAQ) provides users with more usable data than ever before. Enhance the graphing capabilities of the Windows®-based 8800 Controller by overlaying your product’s input, output, and temperature data on a single screen. The same data can be exported to various Microsoft® applications. Available on most chambers, the DAQ features pluggable screw terminal connections, standard jacks, thermocouples, and more. The DAQ panel is easy to set up with the 8800 Controller to begin testing your product.
Door Interlocks

As an optional safety feature the door interlocks prevent the chamber door from opening during a test.
Electronic Humidity Sensor

The Electronic Humidity Sensor is located in the chamber workspace to monitor the humidity levels the product is experiencing. This sensor eliminates the need for maintenance-intensive thermocouple wicks and float tanks.
Low Humidity

A standard humidity system is designed to enable temporary operation down to -10°C dewpoint in a humidity chamber. A low humidity option will enable extended operation down to 5 grains of moisture per pound of dry air minimum limitation and humidity range from 5% RH to 98% RH. The low humidity option on a humidity chamber incorporates a dry air purge for ultra low dewpoints. It also adds a bubbler humidity system which allows small amounts of moisture to be added to the air in the humidity chamber for low humidity control. This eliminates problems associated with adding hot steam to a cold environment which creates two problems: heat that needs to be taken out of the system and steam generator oscillation.
Product Temperature Control

Product Temperature Control (PTC) is a software and thermocouple system used to increase product temperature ramp rates with user-defined temperature offsets. This feature is set up and controlled through the 8800 Controller.

During conventional environmental testing, the workspace air temperature setpoint is achieved before the product temperature reaches it. The product temperature will lag behind and approach the air temperature at an exponentially decreasing rate. PTC reduces product ramp times by up to 50% by over-driving the chamber’s conditioning system until the product temperature achieves the desired setpoint.

In the above example, the workspace air temperature reaches 65°C and holds until the desired product temperature setpoint of 55°C is achieved. Once the product temperature approaches the setpoint, the air temperature converges with the product temperature so both are at 55°C. This ensures accurate test results for your product during environmental testing. PTC works for both heating and cooling. This feature is standard on most models.
Reinforced Floors

Reinforced floors are used in multiple Thermotron chambers. Their purpose is to increase weight handling as well as assist in distributing product load weight.
Shelves

Often times products under test need to be placed on shelves or racks for optimized testing. Shelves and racks are custom made for each application. Every chamber comes with one adjustable shelf, more can easily be added.
Water Purification and Recirculation System

The Water Purification and Recirculation System is an optional feature on humidity systems for Thermotron equipment. This system purifies water to be within the recommended working limits of the chamber and the recirculation aspect takes water that has already be used in the humidity system and reuses it after it has been purified.
Access Port
Access ports are available to easily reach into the environmental chamber to adjust the product under test. Most climate chambers come with one standard port. Additional ports can be added to the environmental chamber. Access Ports are constructed of stainless steel, heliarc welded to the interior liner. Environmental chamber users select the access port size and location at no additional charge. Port availability may vary depending on environmental chamber model. Custom options are available.
The following are the most standard sizes:

3" (7.5 cm)

4" (10 cm)

5" (12.5 cm)

6" (15 cm)

8" (20 cm)- HALT Chamber Only
Custom Colors
You are probably used to only seeing a Thermotron environmental chamber or electrodynamic shaker in just one of two colors – blue and gray. But we can in fact paint your piece of test equipment any color you like, provided you let us know which one.

Custom paint color is an available optional feature for equipment purchased from Thermotron, and the process is quite simple. During the quote process, you work with our Sales and Application Engineers and simply notify them what color you want your test equipment to be painted. We primarily work with RAL and FED-STD-595C – Color Standards, but if you provide us with a color and the standard it comes from we will work with our paint supplier to ensure that your environmental chamber or electrodynamic shaker is painted your specified color.

So, why would you want to have your climate chamber painted a different color? There are many reasons here are a few of the most common:

Branding – customers want to have their equipment painted to promote their brand, and incorporate their branding colors into items their staff and customers see every day.

Grouping – Some customers with many Thermotron chambers in their lab need them to be color coordinated by function, ability, or size.

Safety – We have also had customers request that only certain parts of the environmental chamber or electrodynamic shaker are painted. For example we had a customer paint all electrical panels bright orange to highlight potential safety hazards.

There are many unique reasons to specify a paint color on your environmental chamber or electrodynamic shaker, almost as many as there are colors. What color would you put on your test equipment?
Dry Air Purge

This option enables reduced moisture operation at low temperatures, dewpoints at -40°C. The system consists of a flow meter, regulator and control solenoid for program operation. It utilizes compressed air as the supply source and is very helpful in minimizing moisture in the chamber. This feature is built within the chamber, so no additional floor space is needed.
Humidity

Many Thermotron environmental chambers have the optional feature of humidity to diversify the utility of the climatic chamber. Precise uniformity and tight control characterize the high-performance specifications of the humidity system. Thermotron humidity systems can be configured for a direct-feed facility hook-up or using a water reservoir. The system’s steam generator achieves high volumes of moisture with consistent water vapor levels and more repeatable test result.

The SE-Series Temperature Humidity Chambers have a patented, modular, full-range humidity system. This allows a temperature chamber to be retrofitted and upgraded to a temperature humidity chamber.

Humidity tests can be monitored through the environmental chambers’ controllers.
Product Dewpoint Control
The Product Dewpoint Control (PDC) feature uses algorithms programmed into the 8800 programmer controller to automatically maintain the product to be warmer than the surrounding air. This allows the 8800 to implement the best possible ramp rate to the desired temperature/relative humidity conditions while preventing condensation on the products under test. In the simplest configuration, the product temperature control sensor becomes the PDC sensor when in dewpoint mode. In these chambers, a second control module was added so that 7 additional thermocouples could be distributed inside the chamber. The 8800 algorithm then uses a minimum of eight thermocouple readings (PDC thermocouple + 7 extras) to maintain the correct offset between product temperature and chamber air temperature. The PDC option will be available to customers like other options we provide such as humidity, low humidity, purge, etc. PDC can be retrofitted to existing chambers if the software is updated.

8800 controller algorithms operate the chambers heat and humidity systems in such a way that the chamber air dewpoint remains at a temperature that is lower than the products temperature. Thus, prevents condensation from forming.

Quiet Package

A quiet package is an optional feature that minimizes the noise levels coming from environmental test equipment. Depending on the equipment (electrodynamic shaker or climate chamber) and the size of the environmental test equipment, the quiet package will look and vary in functionality. For more information contact your local sales representative.
Serial Communications Panel

Keep connected with the Serial Communications Panel, featuring computer, Internet, Ethernet, and USB connections all while powering the 8800 Controller. The Serial Communications Panel provides the ability to securely export and transfer sensitive test data including graphs and reports. Included in the Serial Communications Panel are: 2 USB Ports, Ethernet, RS-232, and GPIB/IEEE-488 (optional).
System Monitor

Thermotron's built-in System Monitor streamlines troubleshooting by providing continuous self-diagnostics on refrigeration suction/discharge pressures and temperatures. This reduces maintenance and troubleshooting time by indicating the system malfunction or trip. The feature also tracks running time to aid in preventive maintenance scheduling and restarts the chamber after nuisance trip or power loss (different restarts can be programmed as well).
