FAQ

What is the MOQ (minimum order)?
The MOQ is 1 Pro roll (AS-C 10 = 6 m × 8 cm, from €169 excl. VAT). Pro formats 6 / 15 / 27 m (AS-C 10/25/50) and a 50 m large roll for m³ volumes. Degressive pricing by order volume — tell us your target annual volume in the message.
How is the AS-C ribbon installed?
The ribbon is delivered pre-adhesive. It sticks directly onto a clean, dry wall of the volume to protect (container inner wall, cabinet back, charger ceiling). Installed in under 2 minutes per sticker, no tools.
How does the AS-C ribbon work?
The AS-C ribbon uses a mesoporous SRD material (Self-Regenerating Desiccant) that adsorbs water vapour above 60% RH and regenerates spontaneously when the air dries out. No energy, no maintenance, unlimited lifespan. Learn more.
How does it differ from tub calcium chloride?
CaCl₂ dissolves in the water it captures → corrosive brine to collect and treat, replacement every 3 months, dozens of kg of waste/yr for a container. AS-C stays in place without saturation, waste or collection. Detailed comparison.
Is the product qualified for harsh environments?
Yes — tested in a CNRS climate chamber, validated in real conditions over 85 winter days on EV chargers (see field study) and in a port environment (Capsa containers). Compatible -20 °C / +60 °C.
Can I order samples?
Yes, we provide free samples for technical evaluation. State your needs in the form message.
What is the environmental impact?
AS-C is a zero-consumable, zero-collection-logistics, zero-replacement solution. Over 5 years it avoids dozens of kg of CaCl₂ brine per installation. Our sustainability approach.
