Product catalog summary

Overview

The ESPEC compact thermal shock chamber is designed for high-performance temperature cycling tests on small and low-volume specimens. It features rapid temperature recovery, a compact footprint, and compliance with stringent test standards such as MIL-STD-883E.

Key Specifications and Performance

Temperature recovery time: Less than 5 minutes between +150°C and -65°C zones without auxiliary cooling.
Test area volume: 10.9 liters, accommodating larger specimens such as 210×297mm printed circuit boards horizontally.
Temperature uniformity: Within ±1.5°C for specimens during high and low temperature exposures, ensuring consistent stress application.
Vibration reduction: Soft-move mode minimizes shock to specimens during transfer between temperature zones.
Compliance: Meets MIL-STD-883E and other relevant test standards.

User Interface and Safety Features

Color LCD touch-screen panel for intuitive operation, displaying test patterns, temperatures, cycle counts, and trend graphs.
Specimen protection mechanisms include drive unit brakes and additional safeguards to prevent specimen dropping.
Automatic halt of test area drive and door locking during operation for user safety.
Cable port for easy wiring of specimens for power application or measurement during tests.

Environmental and Energy Considerations

Energy-saving features include electronic auto-expansion valve control and titanium interior materials.
Compact vertical design requires minimal installation space (26 inches footprint).
Use of HFC refrigerant compliant with the Montreal Protocol to protect the ozone layer.
Material labeling and design facilitate recycling of components.
Optional paperless recorder for digital temperature data logging on memory cards.

Test Standards and Compliance

The chamber supports a wide range of temperature cycling profiles compliant with TSE-11-A and MIL-STD-883E standards, covering temperature ranges from approximately -65°C to +150°C with precise control and repeatability.

Options and Accessories

Safety and control options: Leakage breakers, circuit breakers, overheat and overcool protectors, door switches, emergency stop switch, external alarm terminals.
Specimen handling: Stainless steel specimen baskets (5 mesh), cable port rubber plugs, specimen power supply control terminals.
Data recording: Digital temperature recorders (1 to 6 channels), paperless recorders with Compact Flash memory support.
Auxiliary cooling injectors using liquefied CO2 or nitrogen to reduce temperature recovery times.
Communication interfaces: GPIB, RS-232C, E-BUS, RS-485 for integration with external control and monitoring systems.
Additional accessories: Power cords, fixture for floor mounting, color customization of chamber exterior.

Safety Devices

The chamber incorporates multiple redundant safety features including automatic drive halt on door opening, overheat protection for both high and low temperature chambers, thermal relays, compressor protection switches, and motor inverter safeguards to ensure safe operation.

Summary

The ESPEC compact thermal shock chamber offers a high-performance, user-friendly, and environmentally conscious solution for thermal shock testing of small specimens. Its rapid temperature recovery, precise temperature uniformity, and compliance with rigorous standards make it suitable for demanding test environments. The extensive options and safety features enhance operational flexibility and user protection.

A temperature recovery time of less than 5 minutes is achieved in 2 zones ({150Ž and |65Ž) without auxiliary cooling. By realizing a temperature recovery time of less than 5 minutes for the upstream air in the 2 zones ({150Ž and |65Ž), we have achieved performance equivalent to that of a large thermal shock chamber without having to use auxiliary cooling by means of liquid carbon dioxide, which was required in previous compact thermal shock chamber. Complies with MIL-STD-883E and other test standards. This compact thermal shock chamber satisfies the temperature cycle test requirements of MIL-STD-883E...
