UV Sterilizing Garment Cabinet

What is the UV Sterilizing Garment Cabinet?

A UV sterilizing garment cabinet irradiates stored garments with 254 nm UV-C lamps during timed cycles. It provides supplementary surface disinfection for reusable garments stored between wears. It is a supplementary measure only.

Overview

Two to four UV-C lamps of 15–30 W each are placed along the side walls and ceiling, providing irradiance of about 0.5–2 mW/cm2 at the garment surface. Timers of 15–60 minutes run the cycle, and door switches cut lamps when doors open. The interior is reflective stainless steel to increase dose, while hanging rods rotate or garments are hung spaced apart to reduce shadowing. Some models combine UV with filtered ventilation. Units are 304 stainless steel with UV-blocking glass, and power is 220 V at 60–150 W. Lamp life is about 8000 hours. UV degrades some fabrics with long exposure, so cycle time should be validated with the garment supplier.

How does it work?

A garment cabinet provides enclosed storage with controlled airflow so that garments remain dry and particle-free. Basic units have stainless steel or powder-coated steel shelves and hangers with louvred or perforated doors. Ventilated versions draw room air through a prefilter and HEPA filter and circulate it over the garments, keeping positive pressure inside so dust cannot enter. UV-C lamps at 254 nm irradiate hanging garments for surface disinfection, with timers and door switches for safety. Some units include heated drying or nitrogen purge for sterile garments. Doors are glazed for visibility, and interiors are smooth for wipe-down. Units are sized for 1 to 6 persons and supplied as single or multi-door freestanding cabinets.

What are the key features?

• 254 nm UV-C lamps, 2–4 units of 15–30 W
• Timer cycles of 15–60 minutes
• Door safety switch cuts lamps on opening
• Reflective stainless steel interior
• UV-blocking glass doors
• Lamp hour counter

What are the technical specifications?

A typical uv sterilizing garment cabinet configuration offers UV wavelength of 254 nm, lamp power of 2–4 × 15–30 W, irradiance at garment of 0.5–2 mW/cm2, timer of 15–60 min, width of 600–1200 mm and capacity of 3–10 garments. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The UV Sterilizing Garment Cabinet is used in reusable garment disinfection, gowning rooms, laboratory coat storage and biotech facilities. Across the wider Garment Cabinets class, laboratories also deploy it for gowning rooms, pharmaceutical production and electronics cleanrooms.

Which standards and certifications apply?

Relevant standards and methods include ISO 14644-1 (cleanroom classification), ISO 14644-5 (cleanroom operations), EU GMP Annex 1 (sterile manufacturing), GB 50073 (cleanroom design code), IEST-RP-CC003 (garment system considerations) and IEC 61010-1. Certification candidates for this model are CE and ISO 9001 manufacturing; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Place garment cabinets in the gowning vestibule or clean-side change room, away from draughts and wet areas. Clean the exterior and interior with cleanroom-compatible disinfectants at defined intervals, and replace prefilters every 3–6 months. UV lamps lose intensity after about 8000 hours and do not treat shadowed fabric folds, so they supplement and do not replace laundering. Define garment rotation, cleaning and sterilization cycles, and log them. Do not hang wet garments, and avoid storing personal items in the cabinet. Verify that airflow does not raise particles within the gowning room.

How do I select the right UV Sterilizing Garment Cabinet?

Use UV cabinets as a supplement where reusable garments are stored between wears. They do not replace laundering or sterilization. RFQ: lamp count, timer, material and garment capacity. Final selection should be confirmed against the facility design specification and supplier test data.

How does it compare with other Garment Cabinets variants?

Choose by the cleanliness of garments to store and the risk of contamination. For general ISO 7–8 areas, a ventilated steel cabinet may suffice; for sterile or ISO 5–6 garments, use HEPA-ventilated or sterile-purged units. Count the garments per shift and choose the number of compartments or hanger positions, noting coverall volume of about 0.05 m3 per garment. Check door type, glazing and locks, as well as whether UV disinfection is helpful. Verify materials, stainless steel 304 for pharma and powder-coated steel for electronics. Confirm dimensions for gowning-room layout, typical widths 600–1800 mm, and the electrical supply.
