A storage and blast freezer protecting your products

The LSSU offers large scale temperature controlled storage capabilities specific for biotech and pharmaceutical environments.

In addition to large scale storage the LSSU holds the functionality of a blast freezer as well, and will then be a part of the process for producing vaccines, medicine or any other biotech and pharmaceutical products.

With the LSSU – we are reducing complexity – and – we make you problems go away

At LOWENCO, we provide ultra-low temperature storage solutions based on transformative, proven technology that allows biotech and pharmaceutical products to freeze to -80°C with only 0.15°C temperature deviation on the product itself, making the LSSU a reliable and safe cold storage solution.

Our LSSU features advanced blast-freezing capabilities that allow for the rapid freezing of products at ultra-low temperatures and provides a powerful method for safely freezing pharmaceuticals. Moreover, we specialize in optimized solutions for large-scale storage – meaning one LSSU replaces 35 upright freezers, reducing power consumption and leaving the smallest possible footprint. Our strong sustainability profile consisting of products with a long lifetime and 99% recyclability means we can reduce CO₂ emissions by up to 66% compared to traditional cold storage solutions.

Our ultra-low temperature cold storage units are designed to meet or exceed industry standards and regulations, ensuring that your products are stored in the safest and most reliable environment. Additionally, the LSSU operates on our low-energy technology making it highly energy efficient, reducing the total cost of ownership. Want to know more about our low-energy technology? 

Our advanced temperature monitoring systems provide real-time data and alerts to ensure that your products are always kept at the correct temperature. Over 150 alarms provide extensive monitoring allowing full control and preventive troubleshooting.

Ultra-low temperatures and blast freeze for biotech- and pharmaceutical products

Full redundancy and predicted maintenance ensure the safety of your pharmaceutical products

Our Large-Scale Storage Unit, the LSSU, operates on a fully redundant system, meaning that if one system fails, the other takes over. Ultra-low temperatures are critical for the preservation and storage of sensitive materials, such as pharmaceuticals, and other temperature-sensitive products. These materials require precise temperature control and monitoring to ensure their stability and potency. A fully redundant system provides an added layer of protection and security to ensure that your products are always stored in the optimal environment.

Our fully redundant system for ultra-low temperature cold storage provides multiple layers of protection to ensure that your products are always stored at the correct temperature, even in the event of a failure or power outage. Our redundant system features multiple compressors, refrigeration units, and backup generators to provide a seamless transition of power in the event of an interruption. Furthermore, our advanced HMI System, equipped with over 150 alarms, keeps you informed of any potential failures, providing you with alerts in case of system failure.

The LSSU is a high-quality and truly reliable choice for cold storage with low deviation. It offers a safe, easy-to-manage solution with full redundancy, extensive monitoring, and internal and local service.
