Memmert HPP260eco Constant-Climate Chamber, 256 l, 0°C to +70°C

Unrivalled precision for stability testing: the Memmert HPP260eco

The Memmert HPP260eco constant-climate chamber is the gold standard for stability testing, climatic testing and controlled storage in laboratories and research facilities. With a generous volume of 256 litres, this model offers the ideal capacity for medium-sized sample batches whilst maintaining a compact footprint. Thanks to innovative Peltier technology, the HPP260eco operates extremely energy-efficiently, virtually vibration-free and whisper-quiet. Whether for ICH-compliant stability tests (Q1A) in the pharmaceutical industry or demanding material testing in industry – the HPP260eco delivers absolutely reproducible results under highly stable conditions.

Focus on energy-efficient Peltier technology

At the heart of the HPP260eco is the highly efficient Peltier heating and cooling system. Unlike conventional compressor-cooled units, this technology saves up to 90 per cent in energy costs during partial-load operation. Sustainability is another key advantage: as the system operates entirely without refrigerant-based cooling units, it is virtually maintenance-free and environmentally friendly. The precise fine-tuning of the Peltier elements enables extremely small temperature fluctuations, which is a critical quality feature for your validation, particularly during sensitive long-term tests.

Active humidity control for precise conditions

A key performance feature of the HPP260eco is its active digital humidification and dehumidification. An external water tank and a self-priming pump are used to precisely control the relative humidity within a range of 10% to 90% rh. Homogeneous distribution within the chamber is ensured by an optimised ventilation system, so that identical climatic conditions prevail at every point in the chamber. This stability is essential for compliance with strict quality standards and the validation of your processes in the pharmaceutical, cosmetics and food industries.

Maximum control with the TwinDISPLAY

The Memmert TwinDISPLAY ensures intuitive operation and seamless monitoring. Two high-resolution TFT colour graphic displays show all relevant parameters, such as temperature, humidity and fan speed, at a glance. The integrated ControlCOCKPIT software enables legally compliant documentation of process data via USB or Ethernet – a must for GLP/GMP-compliant environments. With the innovative AutoSAFETY system and electronic temperature monitoring, your valuable sample is also protected against deviations at all times.
