Climate chamber TH series

thermostatictemperaturehumidity

Description
The TH series humidity‑freeze test chamber is a climatic test system designed for accelerated aging and qualification of photovoltaic (PV) modules according to IEC 61215 protocols. It reproduces alternating high humidity/high temperature and sub‑zero conditions to evaluate module resistance to moisture ingress and thermal stress. The chamber is suitable for crystalline silicon, thin‑film and concentrator PV modules, and for R&D, production control and third‑party certification.

Overview
Designed to support IEC 61215 Humidity‑Freeze (MQT 12), Thermal Cycling (MQT 11) and Damp Heat (MQT 13) sequences, the chamber cycles modules between 85°C/85% R.H. and −40°C for 10 complete cycles (or per applicable profile). It accelerates lifetime assessment to predict outdoor durability over multiple decades and is aimed at manufacturers, testing laboratories and research institutes.

Product Details
Tests performed in accordance with IEC 61215:2005 and related standards. PV modules are subjected to repeated cycles between 85°C at 85% R.H. and −40°C in a closed climatic space. The protocol assesses moisture penetration, thermal mismatch and mechanical integrity after defined cycle counts.
