EJ Thermal Technologies Inc., a supplier of high performance reliability test systems, has introduced a line of three new LM-80 qualified LED reliability test systems. The HyrdoTower, the Hydropac II and Hydropac IV systems are designed for use by LED manufacturing and packaging companies and are geared to improve testing performance, flexibility, and temperature accuracy.

Reliability test systems are used by LED manufactures to increase the efficiency in testing High power/High brightness LED

The HyrdoTower Tower is a self-contained pentagon shaped system which has up to four independent precision controlled thermal platforms designed to elevate and control the temperatures of LEDs for reliability testing. The tower contains proprietary HydroFlo Amplifier technology that optimizes water flow to the system's four thermal platforms. The HydroTower utilizes a liquid-to-liquid heat exchanger that allows the user to connect to a facility closed loop water system, or a chiller or a liquid to air heat exchanger (Radiator-style).

The system allows LED manufactures to increase the efficiency in testing High power/High brightness LED's and offers a high degree of flexibility. The systems' modular design allows very precise temperature accuracy of  +/- 2 C, at a temperature range of 55-105°C. The independent temperature control of each thermal platform allows the system to be used for 4 separate purposes at the same time, such as burn-in, reliability testing, and engineering product development.

EJ Thermal has also introduced two new bench-top version called The HydroPac II-LM80 and HydroPac IV-LM80. The HydroPac II offers one thermal platform with two test positions and can accommodate power loads up to 3,000 Watts with a temperature range of 35-85°C (optional 105°C). HydroPac IV offers two independently controlled thermal control zones and up to 4 test positions, and can handle power loads to 6,000 Watts at 35-85°C.(Optional 105°C).
