Sams Advanced Climatic Technologies Private Limited

ESPEC developed the TSD-101-W with an interior of 28"x16", while strictly limiting the overall size of the system. The footprint is reduced by 40%, as well as lowering power demand by 60% compared to conventional units. The TSD-101-W has been upgraded to our latest touch-screen controller, which includes a 7" screen and Ethernet access. Uploading/downloading of programs and data can be accomplished over your network. The TSD includes a unique feature called Specimen Temperature Trigger (STT). This STT function actively monitors the temperature of the product and only advances the program to the next step once the product has reached the desired temperature. The STT dynamically reduces the overall testing time by adjusting the soak period according to how much product is being tested.

Product Details:

• A flexible cabling tube (for monitoring or powering samples) that comes out the side, rather than a moving pipe that sticks out the top.
• A cool-down mode allows the operator to safely remove the samples quickly after a test is completed.
• An option for a window makes checking on the samples easier.

Site requirements:

• Main Power: North American standard 208V (alternate international power
• Cooling water supply
• Quiet operation with sound levels below 65dB

Available options:

• Paperless recorder with color display and CompactFlash storage
• Strip chart recorder
• Computer interface (IEEE-488 or RS-232)
• Viewing window
• Additional STT thermocouple inputs
• Additional flexible cable tube

Two-zone chamber capable of exposing specimens to a uniform thermal stress. These two-zone thermal shock chambers are designed to specifically meet the needs of MIL, IEC, JASO and other international testing standards. You can choose from 11L or 100L to fit your testing. They come mounted with The N-instrumentation for improved operability and visibility, making remote monitoring and control via an Ethernet connection possible from your desk. Thermal shock chambers that apply uniform levels of thermal stress to specimens and that can be used in a wide range of fields, from research and development through to inspections and production
With increased modularization and digitization, more electronic parts are used on automobiles in various locations. However, these parts are constantly exposured to high temperatures due to the heat generated by the engine and gears, and the parts are rapidly cooled down by water splashes from the road and rainwater. The developed "Air to Liquid Thermal Shock Chamber" is ideal for reliability and endurance testing of electronic parts exposured to such rapid thermal shocks. The cold chamber adopts a water chamber to apply the specimen to rapid thermal shock. It is impossible to achieve with an air to air thermal shock chamber, thereby creating a thermal shock environment that is more similar to the actual environment.

Unique thermal shock system:

• This unique thermal shock system uses different types of chambers for both the hot and cold chambers, an air chamber for the hot chamber and a water chamber for the cold chamber.

Labor-saving thermal shock testing:

• Conventional thermal shock tests using a water chamber were required manual operation into the water chamber. 
• The specimen is transferred between chambers automatically; the testing can be performed simply by setting the program and reduces labor and time.

Traditional three-zone thermal shock chambers can be quite large, as three separate chambers are used. The TSA series has just one chamber, substantially reducing its size. Instead, it circulates cold, hot, or ambient air as needed. The conditioned air is pre-cooled or pre-heated beyond the setpoint, allowing quicker recovery of the desired condition after transfer. New Eco-Mode is standard for all models. Eco-mode manages the pre-conditioning and modulates refrigeration systems to reduce energy usage. Savings of up to 50% over previous models is possible, or as much as 2,000 a year.

Features:

• "EL" models are lower cost models with only two-zone capability, lower performance, and partial savings of Eco-mode.
• "ES" models have higher performance, three-zone capability, and larger heating/cooling performance that fully benefits from Eco-mode innovations.
• The TSA-73EH-W is configured especially to meet the popular Mil-Std 883 1010 method, from -65 to 150°C.

1000 cycles without defrosting?:

• The new TSA models have a new patent-pending option that allows them to do thermal shock testing for 1000 cycles (or 500 hours) without needing a defrost step. This can save significant test time (other chambers may need defrost every 20-100 cycles), as well as saving additional energy.

Product Details:

• Test samples don't move
• Horizontal airflow design assures uniform results
• Extremely compact systems with a vertically sliding door for added space savings
• Utilizes the latest refrigeration technology: electronic expansion valve and scroll compressor
