What our large-scale solution include

What our large-scale solution include

Engineered for high-density storage volumes of up to 4,800 L/kg, these large-scale units deliver exceptional performance for ultra-low temperature applications.

 

The system maintains a stable temperature range from –20°C to –80°C, with product uniformity within ±1.0°C, ensuring consistent temperature reliability across the entire storage environment.

 

Temperature control is fully adjustable in 0.1°C increments via the HMI, allowing precise fine-tuning to safeguard sensitive materials.

Our blast freezers deliver rapid pull-down with uniform temperature control and a capacity of up to 2,400 L/kg, making them ideal for fast and reliable freezing of high-value materials.

 

Operating within a –20°C to –80°C temperature range, the system maintains product uniformity within ±1.0°C, ensuring every batch freezes under controlled and highly consistent conditions.

 

Temperature control is fully adjustable in 0.1°C increments via the HMI, enabling precise, repeatable freezing and thawing profiles tailored to individual process requirements.

 

Our solution enables products to be blast-frozen and transferred directly into long-term storage within the same environment, without unloading, repacking or any manual handling.

 

This workflow minimizes human touchpoints, reduces temperature exposur, and significantly lowers contamination and traceability risk.

 

A corridor creates a temperature controlled buffer that limits temperature shock when products move in and out of the ULT zone.

By reducing the difference between ambient and ULT conditions, it prevents moisture intrusion, limits frost formation and protects the integrity of stored materials during handling.


This controlled transition zone is a must in any ULT environment, ensuring safer product transfers and consistent and reliable temperature performance throughout the entire storage area.

 

Our corridor temperature range typically between +10°C to -25°C.

Maintains a drier storage environment by limiting moisture transfer and effectively minimizing ice buildup.

The tech space is built on top of the freezers on an integrated ceiling, creating its own dedicated area for maintenance and service.

 

In urban facilities with ceiling-height restrictions, this top-mounted setup can be challenging due to the required clearance.

To accommodate these environments, the compressor units can also be installed in an adjacent technical room and piped back to the LSSU, maintaining full performance while allowing the unit to fit in lower-ceiling spaces.

 

This design ensures uninterrupted operation during maintenance and minimizes temperature fluctuations and product risk by keeping engineers outside the controlled storage area.

The dry cooler is installed outside the building and removes excess heat from the refrigeration system by rejecting it directly to the atmosphere. This dramatically reduces the internal heat load and cuts HVAC energy use by up to 98%.

Build a seamless Cold storage environment

  • Fully integrated workflow
    Products are frozen and stored in the same large-scale cold storage architecture. No repacking or secondary handling is required, which reduces process complexity and operational risk.

  • Minimal human contact
    Operators only move a trolley between freezer modules. This reduces human error.

  • Higher product integrity
    Fewer touchpoints mean lower contamination risk, less temperature deviation, and better preservation of sensitive materials.

Choosing the right ULT storage  solution 

 

Choosing the right ultra-low temperature storage approach depends on several key factors like; how sensitive your stored materials are to temperature fluctuations, how much you need to store today and how your storage requirements may evolve in the future.

 

The guide below can help you assess which model best aligns with your operational profile and long-term strategy.

TRADITIONAL INTEGRATED ULT storage

Best suited for facilities with lower storage volumes, less temperature-sensitive materials and limited long-term expansion plans, where a straightforward multi-freezer setup can meet operational requirements.
  • Storage capacity is typically around 200-400 kg/L per unit, meaning multiple individual freezers are often required to reach the desired storage volume
  • With more units, facilities must allocate larger floorspace for spacing, servicing and HVAC support, creating a more complex layout over time
  • Each freezer operates independently, meaning the system have higher overall energy consumption, with no shared efficiencies between units
  • Traditional panel cooling delivers less uniform airflow due to older engineering principles and the way products are tightly packed inside the freezer, which limits circulation around each product
  • The cooling design and inventory configuration lead to extended temperature recovery following door openings.
  • With multiple standalone freezers and no shared redundancy, system stability often depends on backup solutions

purpose-built LArge-scale ULT Storage

Ideal for organizations handling highly sensitive biologics, expecting significant future growth or needing centralized, efficient and scalable ULT infrastructure designed for long-term performance.

  • Purpose-built systems offer storage capacities up to 4,800 kg/L per unit, enabling much higher output per square meter
  • With fewer larger freezers, facilities can achieve a more compact footprint, using up to 75% less floorspace compared to multiple standalone freezers
  • The integrated storage solution operate at a system level, rather than per unit and therefore delivers up to 80% lower energy consumption
  • The entire storage solution is engineered with forced airflow design, ensuring uniform temperature control around every stored item - even when the storage volume is high
  • The advanced cooling technology and the inventory design increase the temperature recovery time
  • The system architecture incorporates built-in redundancy, allowing the storage environment to remain stable without relying on external backup solutions

FAQ

Our compressor skid is designed for flexibility:


+10°C to –40°C on the same skid
–40°C to –80°C without changing the skid

 

 

The LSSU can be configured with different storage formats tailored to your needs.

Whether you work with bottles, bags, Cryovault containers, or full pallets of small products , we customize the internal layout to ensure maximum density and safe, stable handling.

Lead times typically start from 3 months and up.

Yes. To prevent permafrost buildup, we provide a built-in underfloor ventilation system.

 

A dedicated fan and duct network continuously moves air between the LSSU base and the concrete, ensuring no cold migration into the slab.

Absolutely. Our systems are supported by LOWENCO certified local technicians in both EU and US, with a dedicated Asian service team being added soon.

The LSSU is purpose-built for sensitive biologics that tolereate no temperature excursions from setpoint.

 

Large walk-in cold rooms cannot deliver controlled, uniform temperatures throughout the entire storage environment.

 

The LSSU is engineered for pharmaceutical-grade uniformity (±1°C), fast recovery and stable conditions, something traditional walk-ins simply cannot achieve.

In many urban and city facilities, ceiling heights are limited to around 16’, which makes it challenging to accommodate the standard 20’ clearance required when the compressors are mounted on top of the LSSU.

 

Although the top-mounted compressors are our standard configuration, they do not have to be placed there.

When ceiling height is a constraint, the compressor skids can instead be installed in an adjacent technical area and piped back to the LSSU.

 

This solution enables the LSSU, at its standard height of 12’ to be installed in lower-ceiling spaces without compromising performance or serviceability.
