Thermal Shock Chambers

Energy savings and high reliability in the new series New series thermal shock chambers have been developed to improve our existing models, in terms of reliability, but also in terms of efficiency. Compared to the previous TSA series, the power consumption has been reduced of 35-50%. Energy saving is achieved thanks to the Eco operation mode; the instrumentation automatically adjusts pre-cooling and pre-heating periods and runs operations with just the necessary energy. Improvements in chamber’s reliability. Particular emphasis was placed on removing unnecessary loads and stresses from the refrigeration...

* Equipped with options.

Characteristics Maximum 50% reduction in power consumption with Eco operation mode and new refrigerator control system ● Power consumption amount comparison example (Power consumption amount per cycle by comparing ESPEC chambers) –43% The new series incorporates an algorithm that calculates the minimum operation time for pre-cooling and pre-heating by constantly measuring the amount of heat required for these processes in eco operation mode. This feature can further reduce power consumption and remove the inaccuracies and hassles caused by adjustments based on preliminar y experiments. Tests...

Characteristics Further reductions in power consumption with 500-hour continuous tests 1000 cycles continuous operation EH Type Test start Test time 20-hour reduction (Defrost 1 hour x 20 times) Power consumption amount Consumed power amount to defrost once : 13.6 kWh Consumed power amount to defrost (20 times) : 272 kWh (option: defrost-free operation) Defrost-free operation is provided as an option so 500-hour continuous operation can be performed without interruption (if test conditions are set for 15-minute exposure). Until now testing was interrupted for defrosting when necessary, but ESPEC...

Characteristics The pursuit of high performance, high accuracy, and ease of use. Highly accurate temperature recovery ● Recovery rate & temperature uniformity TSA−202ES−W measurement example +123°C Test conditions High-temp. exposure: +125°C, 30 min. Pre-heating temperature: +145°C Low-temp. exposure: –40°C, 30 min. Pre-cooling temperature: 55°C – Dampers with integrated rectifying function minimize variation in exposure conditions due to specimen position within the test area. This reduces the overall test time and shortens temperature recovery time, especially during low-temperature exposure....

Characteristics Improved reliability. Use our chambers safely and with peace of mind for many years to come. Global safety design Cascade condenser To reduce thermal stress on the refrigerators and prevent corrosion in the circuit, the material and thickness of piping has been changed and this prevents refrigerant leaks. Th rough other cou ntless det ailed improvements, the reliability of the refrigeration circuit has been increased and it can be used safely for many years to come. ● Refrigeration circuit (Parallel refrigeration system: patent pending) The newly developed refrigeration system...
