Thermal Shock Chamber TSA series

Product catalog summary
Overview: The document discusses the TSA Series Air to Air Thermal Shock Chambers by ESPEC CORP, focusing on enhanced energy efficiency and reliability. Key improvements include the Eco operation mode and a new refrigerator control system.
Specifications: The TSA series achieves 35-50% energy savings over previous models. The Eco mode optimizes energy use by adjusting pre-cooling and pre-heating periods. The design minimizes thermal stress and enhances temperature uniformity.
Procedures: A parallel refrigerator control system uses two small refrigerators to optimize power consumption, allowing precise control and reduced power usage during stable low-temperature conditions.
Features: Features include a vertical sliding door for easy access, a round cable port, and an optional wattmeter. The defrost-free operation option supports continuous 500-hour testing.
Test Standards: Compliance with international standards such as MIL-STD-883H, MIL-STD-202G, IEC 60068-2-14, JASO D 014-4, and EIAJ ED-2531A is ensured. The chambers meet global safety standards, including ISO 12100:2010 and CE marking.
Instrumentation: Equipped with a color LCD touch-screen for simplified operation, the chambers offer enhanced test halt and continuity functions, allowing tests to resume or restart as needed.
Refrigeration System: The new system enhances reliability by reducing thermal stress and preventing corrosion, designed to prevent refrigerant leaks for long-term safe operation.
Chamber and Utility Requirements: Specifications for EL, ES, and EH models are detailed, with air-cooled and water-cooled versions. Power supply requirements vary by voltage, with specific amperage, air supply, and cooling water supply rates outlined.
Performance Specifications: Designed for two-zone or three-zone testing, the chambers maintain temperature fluctuation at ±0.5°C. Details on pre-heat, pre-cool limits, and recovery conditions are provided.
Construction and Materials: Constructed with rust-proof treated steel and stainless steel interiors, insulation is provided by glass wool and rigid polyurethane foam. The refrigeration system uses a mechanical cascade system with specific refrigerants.
Safety Devices: Includes leakage breakers, circuit breakers, overheat protection switches, and various relays and protectors for safe operation.
Accessories and Options: Accessories include specimen baskets and shelf brackets. Options for extended testing without defrosting are available, reducing test time and power consumption.
Warnings and Cautions: Users are cautioned against using explosive, flammable, or corrosive substances. Reading the user manual before operation is emphasized for safety and proper use.

Thermal Shock Chamber TSA series-2

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...

Thermal Shock Chamber TSA series-4

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 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....
