Our popular Ultra-Low Temp Suite utilizes an innovative chamber-within-a-chamber design to support the stringent bio-repository and pharmaceutical requirements of ultra-cold temperature walk-in freezer vaults. It offers a more energy efficient alternative to the traditional “freezer farm” approach, while still delivering maximum capacity, multi-temperature storage flexibility, and frost-free product protection.
Each suite can be designed to your explicit size, temperature, and electrical-controls specifications, or you may adapt your operation to utilize one of our standard layouts. Commonly, the suite utilizes multi-door vaults that are capable of temperature setpoints of -60, -70, -75, or -80°C, located within -20 to -40ºC freezer corridors, that are designed to share a central cascade refrigeration system.
To maximize energy efficiency and reduce the need for mechanical maintenance, the Ultra-Low Temp Freezer areas are designed with no fans or moving parts. They produce extremely uniform storage conditions but are not designed to freeze products. In order to assist in preparing products for storage, we can design special compartments for blast freezing your products, if necessary.
This suite is ideal for biopharma production and biorepository applications. With flexibility of chamber depth and door dimensions, a variety of product storage containers can be utilized, including bottles, plates, small vials, bulk drums, and canisters. Built to include shelving or to allow full carts to be rolled into place, the suite offers multi-temperature storage for a wide variety of products, including samples of drugs and various biological products.
To maximize the utilization of your valuable floor space for bulk storage applications, the suite can be constructed as open walk-in space, rather than multi-door vaults, achieving temperature setpoints as low as -80°C. Entry to the Ultra-Low Temp Freezer is made thru a small unconditioned vestibule that leads into an anteroom conditioned to -20°C. This solution helps achieve the highest storage density and fastest recovery time possible while maintaining the frost-free performance we are known for.
Knowing that the products stored in at these temperatures are extremely valuable, if not irreplaceable, all critical systems are fully redundant. Each freezer compartment in the suite, as well as the personnel corridor(s), has duplicate refrigeration systems for full redundancy with automatic periodic switchover to exercise each system to help ensure proper function. We don’t stop there. Additionally, in the event of full power loss at your facility, the suite includes the unique option of refrigeration from a parallel LN2 system with controls powered via UPS. Finally, loss of power does not mean loss of product.
Our Ultra-Low Temp suite concept was first constructed in 1999 and that original freezer is still in use. The extremely high value of products stored in these freezers demands specialized expertise in design, installation, and maintenance. The Environmental Specialties team is uniquely qualified to excel in all three facets, delivering a world-class product backed by professional experts for worry-free performance year after year.
As the following table illustrates, not all ultra-low temp walk-in systems are created equal. Protect your high-value products with the proven technology and experience of Environmental Specialties.
Along with outperforming similar walk-in freezer systems, our suite also offers a number of advantages over traditional ultra-low temp (ULT) "freezer farms,” as outlined on the chart below.
Because our suite has a significantly lower chamber count than a commercial freezer farm, our clients often see as much as a 33 percent reduction in building space consumption when they switch.
Depending on the size of your existing ULT freezer farm, how much space would you save with one of the following standard layouts?
Further, our solution can also help drastically improve efficiency. Saving hundreds of thousands of both kWh and pounds of CO2 emitted annually, our solution can offer a 75 percent reduction in total energy consumption. The result is an economical, space-saving product line that combines maximum capacity, multi-temperature uniformity with energy efficiency and cost savings.
Environmental Specialties’ Ultra-Low Temp suites give you high-performance operation, significant cost savings, and greater dependability than ever before.
