• 749L volume, stainless steel interior climate chamber
• Temperature range: 0 to +70°C, accuracy: 0.1°C
• Humidity range: 10 – 90% rh, accuracy: 0.5%
• Max loading of chamber: 200 kg (440.9 lbs.)
• Advanced Peltier technology is 90% more energy efficient than condenser cooled chambers

The Memmert HPP750eco constant climate chamber provides maximum energy efficiency in continuous operation. The HPPeco series chambers require low maintenance and have a long service life. The HPP750eco provides the perfect atmosphere for climate and temperature tests. The constant climate chamber is tailored to environmental simulation, material testing, and stability testing in accordance with ICH guidelines. It is a cost-effective, eco-friendly, and reliable solution for critical stability testing. 

Equipped with advanced Peltier technology, the constant climate chamber works around 90% more energy efficiently than compressor-cooled devices. Due to the environmentally friendly Peltier elements, the HPPeco has no need for refrigerants and requires no regular maintenance.

The main part of stability testing is performed at temperatures between +20°C and +30°C – close to the ambient temperature. The impressive cost effectiveness of the HPPeco with advanced Peltier technology can be seen in the graph below:
