AIRsteril ULTSA — Ultimate Small Area Cold Room Disinfection Unit (up to 110m³)

Description

AIRsteril ULTSA — Ultimate Small Area Cold Room Disinfection Unit

The AIRsteril ULTSA brings the same five-technology disinfection approach as the larger ULT range into a compact format designed for smaller cold rooms, single chiller cabinets, small display fridges, butcher chillers up to around 25m² floor area, and smaller bakery cold storage. One ULTSA treats up to 110m³.

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 using ULTSA specifically)
• Pichia anomala mould: 83% surface reduction in 24 hours; undetectable by day 2

Five Disinfection Technologies — Compact Format

1. UV-C germicidal irradiation
2. Photocatalytic Oxidation (PCO) with titanium dioxide catalyst
3. Superoxide ions for ultra-fine particulate removal (down to 0.0001 micron)
4. Targeted ozone for surface and corner reach
5. “Plasma Quatro” combined action

Same internal IP68 24V DC fan (150 CFM) as the ULT range, same baffle dwell-time geometry, same food-grade FEP-wrapped UV-C lamp specification — just in a smaller, lower-wattage cabinet sized for smaller rooms.

ULTSA installed in a working cool room — wall-mounted, continuous operation.

Technical Specifications

• Coverage: up to 110m³ per unit
• UV-C lamps: 1 × 20W food-grade FEP-wrapped (shatterproof)
• Cabinet: 550mm × 250mm × 125mm stainless steel
• IPX5 waterproof rating
• Power: 220-230V, 22W (very low energy consumption)
• Weight: 6kg
• Mounting: wall-mounted, 4 fixing points
• Operation: continuous 24/7/365
• Servicing: annual lamp change and internal clean

Applications

• Small butcher chillers and counter cool rooms
• Small bakery cold storage
• Restaurant walk-in cool rooms
• Café and food service cold storage
• Delivery vehicle cold storage and back-of-house
• Single-tenancy retail food cool rooms
• Multi-unit deployments where coverage is segmented (e.g. 2 × ULTSA = 220m³)

When to Choose ULTSA vs ULT

Use the ULTSA where the cold room is under 110m³ (around 25-30m² floor with standard ceiling height). For larger rooms, the ULT range gives better economy-per-cubic-metre and a single unit can cover up to 440m³. We can spec the right configuration on application — there’s no extra charge for sizing advice.
