Themal Shock Test Chamber TSA Series

About

Higher performance

The TSA Series aims at fulfilling high-level requirements for thermal shock testing.
The advanced model achieves 1000-cycle consecutive tests without defrosting （option）, and offers reduced temperature recovery time, heat up and pull down time.
Features an eco operation mode for more energy savings.

Reduced power consumption

With the eco operation mode, operating time is shortened by temporarily suspending temperature pre-conditioning periods.

Reduced test duration

In 2 zone test, the TSA achieves 1000-cycle consecutive test （500-hour） without activating defrost operation usually required. This allows dramatic reduction of the overall test time.

TSA-71L		W410×H460×D370 / W1310×H1900×D1370
TSA-101L		W650×H460×D670 / W1550×H1900×D1370

Features

Short temperature recovery time
The maximum temperature recovery time at upstream air for 2 zone test （+150°C and -65°C） and 3 zone test is only 5 min. （10 min. for TSA-201S and TSA-301L）
Great uniformity
Horizontal air flow system offers excellent specimen temperature uniformity.
Efficiency thanks to specimen temperature control （option）
Thanks to this feature, the equipment achieves set temperature attainment with rapidity and accuracy.
STT function （option）
Thanks to the specimen temperature monitor with trigger, exposure time starts only when the specimen has reached the set temperature, leading to more precise test results.
User-friendly controller
The LCD touch-screen controller allows easy check of the test patterns, temperatures settings, test cycles and graph displays.
Reduced load current
Reduced operating noise

Energy-saving

Reduced operating time
The eco operation mode reduces the operating time by temporarily suspending following periods:
- Pre-cooling of the low temperature chamber during high temp. exposure,
- Preheating of the high temperature chamber during low temp. exposure.Thanks to the eco operation mode, power consumption is dramatically reduced especially for long exposure time, and tests requiring many cycles. （except TSA-41L）
Unique chamber structure
（Patent No. 3514735）
ESPEC’s unique design enables 1000-cycle （500-hour） without defrosting in 2 zone test. The structure prevents outside air to penetrate, which is usually causing frost. Constant environmental conditions are maintained, thus expanding the defrost-free operation range.

*Models supporting defrost-free operation
TSA-71H-W: 1000 cycles （500 hours）
TSA-201S-W: 500 cycles （500 hours）
Continuous operation is not supported for
some test conditions.
