Description
AIRsteril ULT — Ultimate Range Cold Room Disinfection Unit
The AIRsteril ULT is a continuous-operation air and surface disinfection system designed specifically for working cold rooms, meat processing chillers, boning halls, butcher cold storage, bakery storage, and commercial food cool rooms. A single ULT4 unit treats up to 440m³ — typically around 100m² floor area with a standard cold room ceiling height. Smaller variants (ULT1, ULT2, ULT3) are available for smaller volumes.
Independent Lab-Validated Performance
- 58.1% average shelf life increase in mixed-produce cold storage (ALS Laboratories, Rotherham)
- 76% reduction in airborne contamination (ALS cold room trial)
- 45% improvement in surface hygiene (ALS cold room trial)
- EU beef trial: Total Viable Counts driven from 1,000–2,500 cfu/cm² down to 41–96 cfu/cm² — well below EC 2073/2005 regulatory target of 250
- Listeria monocytogenes: reduced to undetectable within 3 days (ALS lab testing)
- Pichia anomala mould: 83% surface reduction in 24 hours; undetectable by day 2
Five Disinfection Technologies in One Sealed Unit
- Dual UV-C germicidal irradiation
- Photocatalytic Oxidation (PCO) with titanium dioxide catalyst
- Superoxide ions for ultra-fine particulate removal (down to 0.0001 micron)
- Targeted ozone for surface and corner reach
- “Plasma Quatro” combined action
Air is drawn in by an internal IP68 24V DC fan (150 CFM), passes through a baffle system that maximises dwell time in the UV-C chamber, and leaves the unit as an active cleaning agent that continues to work on airborne and surface contamination throughout the room.
