IMPROVED PERFORMANCE

Air Baffle

Optimizing the airflow in the work area is essential for a successful test. Repeat tests and maintain consistent, accurate results with Thermotron’s innovative air deflector. It is designed to evenly and forcefully distribute air directly onto the product,* ensuring that the entire product is conditioned. The superior airflow provided by the air deflector improves product temperature change rates, narrows temperature gradients and improves uniformity throughout the chamber working space.

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 configured and controlled via the 8800 controller. During conventional environmental testing, the workspace air temperature setpoint is reached before the product temperature reaches it. The product temperature will lag behind and approach the air temperature at an exponentially decreasing rate. The PTC reduces product ramp times by up to 50% by overdriving the chamber air conditioning system until the product temperature reaches the desired setpoint. In the example above, the workspace air temperature reaches 65°C and holds until the desired product temperature setpoint of 55°C is reached. As 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 the product during environmental testing. PTC works for both heating and cooling.

Energy Saving (optional)

This innovative feature increases cooling performance and reduces chamber energy consumption. Power Saver Plus mode works with the 8800 controller to determine whether to operate in single-stage or cascade mode, based on the temperature setpoint, humidity mode, and cooling throttle. Single-stage refrigeration systems operate faster in the higher temperature ranges, while cascade refrigeration systems operate faster in the lower temperature ranges. Power Saver Plus combines the advantages of both systems. It uses sophisticated control logic to allow switching between systems, thereby increasing cooling ramp times by up to 30%, all while reducing energy consumption.

Heating/Cooling Boost (optional)

Additional features enhance the cooling and heating performance of the chamber. LN₂ Boost and CO₂ Boost Liquid nitrogen (LN₂) boost and carbon dioxide (CO₂) boost are cooling injection systems that enable faster heat removal and dissipation from the product under test. Extra Heat This additional feature accelerates the heating capabilities of the chamber to improve the rates of change of air and product temperature.

8800 CONTROLLER

Intuitive, robust, safe

The exclusive Thermotron 8800 Windows®-based controller with 12-inch color touchscreen makes chamber operation and data collection easy and reliable. Quick navigation buttons provide shortcuts to user-selected screens.

The 8800 controller is standard on all SE Series cameras. With this controller, you get:

• Multi-level password-based security system to protect data

• Test data that can be downloaded in spreadsheet formats

• An activity register: records and maintains more than 15 years of chamber history

• Product temperature control to improve product change rates by overcompensating air temperature to control product temperature

• System Monitor to detect excessive refrigeration pressures and temperatures and alert users when problems occur

• Product dew point control to prevent condensation by keeping the product at a higher temperature than the dew point of the surrounding air (optional)

• ThermoTrak II™ for connecting up to 32 controllers to one PC (optional)

MODULAR HUMIDITY SYSTEM

Temperature-Humidity

SE Series chamber models include a patented, modular, full-range humidity system. Precise uniformity and tight control characterize the high-performance specifications of this humidity system. With excellent low humidity accuracy, the electronic humidity sensor (located in the work area) eliminates the need for thermocouple wicks and float tanks. A steam generator achieves high humidity volumes with consistent water vapor levels and more repeatable test results. The humidification system can be configured with a direct feed plant connection or a self-contained refillable water tank. If the water tank is used, the wet water purification and recirculation system is recommended to keep water within the working limits of the chamber. A demineralizer cartridge viewing window allows users to see the cartridge without opening the doors. The low humidity option incorporates dry air purge and a bubbler humidity system to control humidity to extremely low dew points. This eliminates the two problems associated with adding hot steam to a cold environment: heat that must be removed from the system and oscillation of the steam generator, which negatively impact test results. Humidity test numbers can be viewed, monitored and controlled using the 8800 controller. If you have a temperature-only chamber, the modular humidity system can be added as a retrofit in the field.

UNIVERSAL DOOR

The patented Universal Door can be installed in the side wall of the SE Series chambers, expanding the capabilities of the chamber by diversifying equipment usage, increasing laboratory productivity, and reducing capital investment costs. The Universal Door interfaces with interchangeable modules and accessories that feature different stress testing and simulation techniques, allowing the chamber to serve multiple purposes. With the Universal Door, a temperature chamber can become a HALT chamber, a thermal shock chamber, or a remote air conditioner without the need to purchase an additional chamber. The height of the Universal Door, modules, and accessories is consistent across all SE Series chamber models. The stainless steel door reduces moisture migration and heat loss.
