What is the difference between this and the HCP humidity chamber?
Both appliances simulate temperature-humidity combinations. Whereas the HPP constant climate chamber can be operated in a temperature range from +5 °C to +70 °C, the HCP humidity chamber works in the range from +20 °C (8 °C above room temperature) to +160 °C – and with humidity, to +90°C. The HPP is based on Peltier technology, while the HCP humidity chamber is equipped with the tried and tested Memmert all-round surface heating. Through the use of Peltier elements, the HPP constant climate chamber is designed for long-term experiments, such as ongoing stability tests in accordance with the ICH guidelines, and at temperatures close to ambient temperature and over many months can save up to 90% of energy compared to compressor-cooled appliances.
Does the performance of the Peltier elements decrease over the years?
The core of a Peltier element consists of semiconducting materials, which are virtually wear-free. Two aspects determine its duration of life: manufacturing quality and above all an extremely sensitive temperature control. Memmert has a leading position in this field due to its in-house development of the own controllers. Thus the gentle switchover between hot and cold minimizes the thermo-dynamic stress on the modules.
Since the first IPP Peltier-cooled incubator was launched in 2000, thousands of Memmert Peltier appliances have been sold. Until now there have been no complaints or repairs because of the failure of a Peltier element.
