Integrated cold storage solution

Engineered as one centralized infrastructure

Our large-scale cold storage solution consolidates capacity into a centralized, integrated infrastructure designed around your facility, storage requirements and long-term capacity needs.

 

Aligned with Pharma 4.0 principles, the architecture reduces complexity, connects systems with your facility's wider data ecosystem and creates a more scalable and manageable cold storage infrastructure.

LOAD ONCE | BLAST FREEZE | STORE LONG TERM

  • No repacking between processes 
    Move products in the same trolley or inventory configuration between freezing and long-term storage, reducing unnecessary handling and process steps.

  • Fewer operator touchpoints 
    Reduce manual transfers and interventions across the cold storage workflow, lowering operational complexity and the opportunity for handling errors. 

  • Protect product conditions
    Fewer transfers mean less exposure outside controlled storage conditions and a more consistent cold chain for sensitive materials.

When does a large-scale cold storage solution become relevant?

 

Choosing the right ultra-low temperature storage approach depends on several key factors.

Upright freezers can be a practical solution when storage requirements are limited.

 

But as capacity grows, adding more individual freezers also increases the number of assets, facility interfaces and operational requirements that need to be managed.

 

At scale, it becomes relevant to evaluate cold storage as infrastructure rather than as individual equipment.

Individual upright freezers

A practical solution at lower storage volumes

Upright freezers work well when storage requirements are limited and capacity growth is predictable. But as volume increases, every additional freezer add another asset to power, monitor, maintain and qualify. 

 

  • Storage capacity is typically around 200-400 L per unit. Lower storage density means more individual freezers are required as capacity grows.
  • Footprint grows with every added freezer. More units require more GMP floorspace, HVAC capacity, maintenance and validation.
  • Energy scales with asset count. Each freezer operates independently, so total energy consumption increases as more units are added.
  • Traditional panel-cooled designs can be more sensitive to inventory configuration and tightly packed products, which may restrict airflow.
  • With a single refrigeration system per unit, resilience often depends on spare capacity, backup freezers or operational contingency plans.

LArge-scale COLD STORAGE

Designed for growing and high-volume storage requirements

When cold storage starts to affect floorspace, utilities, operations and long-term expansion, an integrated approach allows capacity to be managed as infrastructure rather than as a growing collection of individual assets.

  • Storage capacity is typically up to 4,800 L per unit. The GMP freezers consolidate significantly more storage into each unit, increasing storage density per square feet.
  • Fewer, larger units create a substantially more compact cold storage footprint and release valuable facility space by up to 75%.
  • Up to 73% lower energy consumption due to Integrated refrigeration architecture that delivers large-scale capacity with significantly lower energy demand.
  • Forced-air circulation designed to maintain uniform conditions throughout the storage environment, supporting ±1°C product temperature uniformity.
  • Dual-redundant refrigeration architecture designed to maintain critical storage conditions if a cooling component is unavailable ensure no operational downtime.

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.
