POA

​Designed for laboratories that cannot afford compromise, the Stirling Ultracold VAULT100 PRO ULT freezer delivers superior sample protection, faster recovery, lower operating costs, and simplified serviceability.​​​​​​​​​

Description

​The Stirling Ultracold VAULT100 PRO​ delivers superior sample protection, faster recovery, lower operating costs, and simplified serviceability.​​​​​​​​​

  • ​Temperature range: -100°C to -20°C
  • Quick Change free-piston Stirling Engine
  • Industry-leading temperature uniformity
  • Rapid temperature recovery after door openings
  • Adaptive cooling technology eliminates traditional on/off cycling
  • Samples remain protected even during routine access events​

​The VAULT100 PRO maintains exceptionally stable storage conditions, helping preserve valuable samples and minimise temperature excursions.

Unlike traditional ULT freezers that can require lengthy refrigeration repairs, the VAULT100 PRO features a bolt-on condenser assembly that allows refrigeration system replacement in approximately one hour. This innovative design enables service to be completed before product temperatures reach critical thresholds, helping safeguard valuable research and biological materials.​

​Built for Maximum Uptime

The Stirling Ultracold VAULT100 PRO​ features a quick-change refrigeration system that allows qualified service personnel to replace critical refrigeration components in approximately one hour—without hot work requirements​.

​Benefits include:

  • Industry-leading reliability
  • Fastest mean time to repair
  • Six-year engine and thermosiphon warranty
  • Fewer service disruptions
  • Reduced operational risk​

Powered by Stirling engine technology with only two moving parts, the VAULT100 PRO eliminates many of the failure points associated with traditional compressor-based systems.​
