Enact Holdings: Stirling Ultracold's VAULT100™ Freezer Achieves Unprecedented Energy Efficiency Standards

Revolutionizing Laboratory Storage Solutions: Stirling Ultracold's VAULT100™ Freezer Sets New Standards in Energy Efficiency

In a significant advancement for laboratory equipment, Stirling Ultracold announces that its VAULT100™ upright freezer achieves an Environmental Impact Factor (EIF) score of 23, the lowest ever recorded for an ultra-low temperature (ULT) model in the ACT database as of March 28, 2025. This milestone is a testament to the company's ongoing commitment to sustainability and energy efficiency in laboratory settings. The VAULT100 freezer, which replaces the SU780XLE model, not only maintains the same storage capacity and external dimensions but also introduces an impressive temperature range of -100°C to -20°C. This allows for enhanced versatility in sample storage without compromising on energy use, making it an ideal solution for laboratories that require reliable access to stored samples.

The successful completion of the ACT Ecolabel audit by My Green Lab underscores the VAULT100's environmental credentials. Alongside its impressive EIF score, the freezer also earned scores of 35.3 for the EU and 35.4 for the UK, indicating a significant reduction in environmental impact compared to other models in the market. Stirling Ultracold's innovative approach, utilizing free-piston Stirling engine cooling technology, sets a new benchmark for energy efficiency. The newly developed M6D Stirling engine offers reduced power consumption and improved performance, which not only minimizes operational costs for laboratories but also aligns with the growing demand for sustainable laboratory practices.

CEO Clayton Newman emphasizes the importance of this achievement, stating that the validation from My Green Lab confirms the company's dedication to reducing environmental impacts within the lab equipment sector. The VAULT100 freezer's ability to maintain temperatures below -70°C for up to two minutes with the door open demonstrates its superior design and user-friendly features. This capability is particularly beneficial for laboratories engaged in time-sensitive research, where quick access to stored samples is essential. As Stirling Ultracold continues to lead the way in the ultra-low freezer market, the VAULT100 freezer represents a significant step forward in combining performance with sustainability.

In addition to the achievement of the VAULT100, Stirling Ultracold's focus on innovation positions the company as a frontrunner in the laboratory equipment industry. The introduction of energy-efficient solutions reflects a broader trend within the sector, as laboratories increasingly prioritize sustainability to meet regulatory requirements and societal expectations. The VAULT100's groundbreaking technology not only enhances operational efficiency but also contributes positively to the environment, reinforcing the importance of sustainable practices in scientific research.

As the demand for eco-friendly laboratory solutions grows, Stirling Ultracold's commitment to innovation and sustainability will likely influence the future of ultra-low temperature storage, offering laboratories a reliable and environmentally responsible option for their storage needs.
