The Gram ER 660W refrigerator: performance and safety for your biomedical applications
The Gram ER 660W refrigerator is a biomedical storage device specially designed to ensure optimal preservation of the most sensitive samples and biomaterials. This model stands out for its ability to maintain a constant temperature and a controlled internal atmosphere. With a net volume of 484 litres and a robust design, the ER 660W meets the most stringent safety and performance standards.
One of the key features of this refrigerator is its Gram BioLine air distribution system, a technology that ensures uniform temperature distribution throughout the chamber. This system minimises temperature fluctuations, even when the door is opened frequently, to prevent any risk of sample degradation. In addition, precise control of internal humidity helps prevent condensation and reduces the likelihood of contamination, a crucial advantage for storing fragile biomaterials.
The ER 660W also features an ergonomic control panel that provides continuous and intuitive monitoring of parameters. This device includes individually programmable audible and visual alarms that immediately alert you in the event of abnormal temperature variations or prolonged door opening. A voltage-free contact allows the refrigerator to be connected to an external alarm system for enhanced security, which is essential in situations where even the slightest failure can have critical consequences. The screen lock function and alarm logging ensure reliable management in accordance with the most demanding quality protocols.
The ER 660W is designed with durability and flexibility in mind. Its stainless steel interior guarantees optimal resistance to intensive use and facilitates cleaning, reducing the risk of cross-contamination. Modular shelves and drawers allow the interior layout to be adapted to the specific needs of each user, whether for reagent bottles, blood samples or temperature-sensitive pharmaceutical products.
Designed to operate in an ambient temperature range of 10°C to 43°C (or up to 38°C for the glass version), the ER 660W maintains its performance even in harsh environmental conditions. Its 60 mm thick polyurethane foam insulation, combined with the use of environmentally friendly HFC-free refrigerants such as R290, demonstrates Gram's commitment to sustainability and environmental protection.
Compliance with ATEX Category 3 Zone 2 standards allows the ER 660W to be installed in potentially explosive areas, making it a versatile solution suitable for a wide range of industrial and medical contexts. In addition, the unit's low noise level, rated at only 48.5 dB(A), ensures optimal user comfort, even in shared workspaces.
The Gram ER 660W refrigerator is a cutting-edge technological solution that combines precision, safety and environmental friendliness to meet the most complex needs of healthcare and scientific research professionals. Its ingenious design, multiple customisation options and superior performance make it the benchmark choice for storing the most sensitive biomaterials.
