Large rapid temperature transformer box
Large rapid temperature change test chamber: The test space of this model is 2.7m ³, with non-linear cooling and a cooling rate of 10 ℃/min. Model: ES
Product details
Product Features
Reasonable structural design, optimized refrigeration design, wind speed variable frequency regulation, fast temperature rise and fall speed (linear SC and nonlinear C cooling methods are optional).
High control accuracy, temperature fluctuation ≤ ± 0.5 ℃, temperature deviation better than ± 1.5 ℃.
The temperature change rate is fast, and the mechanical cooling rate meets the temperature rise and fall requirements of 5 degrees per minute, 10 degrees per minute, 15 degrees per minute, and 25 degrees per minute. Coupled with a liquid nitrogen assisted cooling system, the cooling rate can reach 30 ℃/min.
The experimental volume can be increased from 64 to 1000 liters, which basically meets all customer needs.
Humidity requirements can be customized as needed.

Product Usage
Environmental Stress Screening (ESS) is specially designed for rapid temperature change testing that meets customer requirements.
Environmental Stress Screening (ESS) refers to a method of testing for screening the climate, thermal, or mechanical stresses that a sample may come into contact with, which could lead to premature failure. For example, it can detect deficiencies in electronic module design, materials, or production.

Through Environmental Stress Screening (ESS), unreliable systems that have entered the production testing phase can be identified as a standard method for quality improvement, effectively extending the normal working life of products.

A: Electronic component environmental stress screening (impact fatigue) service life curve F: product defect T: time 1: early defect 2: service life 3: aging stage
