votschtechnik Clean Room Hot Air Sterilisers (ISO 5), VHSF
Sterilisation for High Purity Environments
Simultech presents the VHSF series by vötschtechnik (Weiss Technik) — hot air sterilisation cabinets designed explicitly for ISO 5 clean rooms. These units use dry heat and controlled laminar HEPA air flow to sterilise or depyrogenate glassware, medical containers, and thermally stable equipment — all without chemicals.
The integrated HEPA circulating air filter is placed directly before the intake to maintain ISO 5 compliance, while laminar flow ensures homogeneous temperature distribution. 
Key Features & Benefits
Reliable Hot Air Sterilisation for Controlled Environments
The Vötschtechnik VHSF series is designed for precise and reliable hot-air sterilisation in ISO 5 clean-room conditions. Each unit combines high-performance airflow and temperature uniformity to meet GMP and FDA validation standards, ensuring safe sterilisation of glassware, metal containers, and laboratory tools.
Equipped with an integrated HEPA filtration system, the VHSF steriliser maintains particle-free air circulation, while advanced control technology provides accurate process monitoring and documentation. Available in pass-through and wall-mounted configurations, it supports seamless installation in pharmaceutical, medical, and biotechnology facilities where contamination control is critical.
With operating temperatures up to 350 °C and durable stainless-steel interiors, these clean-room hot air sterilisers offer long service life and consistent results. The VHSF range delivers the reliability and precision expected from Vötschtechnik by Weiss Technik, setting the benchmark for high-purity sterilisation environments.
1. ISO 5 class compliance — Meets clean room criteria per DIN EN ISO 14644-1 with HEPA filtration and sealed interiors.
2. High-temperature sterilisation — Operates up to 350 °C for full sterilisation, including depyrogenation cycles.
3. GMP / FDA readiness — Designed for pharmaceutical, biotech and medical manufacturing environments.
4. Uniform laminar flow — Ensures minimal temperature deviations across loads.
5. Flexible installation — Available as standalone, wall-mount, or pass-through versions (front/back doors with interlock).
6. Energy recovery & efficiency — Options include cross heat exchangers for waste heat recovery to reduce operating cost.
Additional standard / optional specifications include:
• Sealed, welded interior in GMP-grade stainless steel.
• Automatic door closing and electric interlocks in pass-through models.
• Pressure-controlled chamber, HEPA filter monitoring, and S!MPAC® system for process control and validation.
• Pharma qualification documentation (DQ, IQ, OQ) available.
Applications
VHSF clean room sterilisation is ideal for sectors including:
-
Pharmaceutical vials, bottles, ampoules
-
Medical components and instruments
-
Biotechnology production lines
-
Laboratory & analytical equipment requiring depyrogenation
-
Cleanroom manufacturing in ISO 5 environments
Because the process uses only hot air and no chemicals, it is clean, safe, and well suited for regulated environments.
