Step 1 — Calculation

Estimate your AS-C sticker needs

Enter the air volume to protect and the thermal amplitude. The calculation is based on our thermodynamic model validated in a CNRS laboratory.

Air volume to protect

20' container ≈ 33 m³ · Industrial cabinet ≈ 1-3 m³

Max temp (day)

Min temp (night)

Expert mode ▸ initial RH and thermal ramp

Initial RH (%)

Default : 65 % — typical European industrial workshop. Adjust for wetter or drier environments.

Default : 0.043 °C/min (typical outdoor daily cycle). Limit : 0.5 °C/min (storm thermal shock). The faster the ramp, the more stickers are needed.

Step 1b — Return on investment

Calculate your ROI vs calcium chloride

The AS-C sticker is a one-time investment. Tub CaCl₂ is a recurring consumable. Estimate your net savings based on your consumption and the market price excl. VAT.

Number of installations to equip

AS-C stickers per installation

From the calculator above. 1 sticker = 25 cm × 8 cm (200 cm²) covers ~20 L.

CaCl₂ consumption per installation (kg/yr)

Assumption : 2 kg tub replaced every 3 months (4 cycles/yr = 8 kg).

Average CaCl₂ price excl. VAT (€/kg)

Average price excl. VAT for 1-2 kg absorber tubs (Pingo, Humydry pro, ManoMano, Castorama Pro) : 4 to 7 €/kg.

Annual labour cost per installation (€/yr)

Assumption : 4 visits × 30 min × €80/h loaded + travel ≈ 200 €/yr. Adjust to your context.

Amortization horizon (years)

Total stickers : 250 · ≈ total area : 5 m²

Applied price : €4.49 /sticker (Pro pricing (AS-C 100)).

AS-C investment (one-shot) €923

CaCl₂ material cost avoided €2,000

Labour cost avoided €10,000

Total cost avoided (over the period) €12,000

Net savings +€11,078

ROI +1201%

Payback 5 months

Material impact over the period:

CaCl₂ avoided

400 kg

Brine avoided

~600 L

Excl. VAT : investment = N × stickers/install × €4.49/sticker (Pro AS-C 100 pricing, i.e. €449 excl. VAT per lot of 100 stickers ; volume discounts on quote) · savings = N × (kg/yr × €/kg + labour/yr) × horizon. Labour cost includes quarterly visits and travel. Full methodology →

FAQ

What is the MOQ (minimum order)?

The MOQ is 1 Pro lot (AS-C 20 = 20 stickers, from €159 excl. VAT). Pro lots of 20 / 60 / 100 stickers (AS-C 20/60/100) ; other formats made to order, on quote. Online orders are limited, per customer per day, to 3 AS-C 20 lots and 1 AS-C 60 or AS-C 100 lot; beyond that, on quote. Degressive pricing by order volume — tell us your target annual volume in the message.

How is the AS-C sticker installed?

The sticker 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 sticker work?

The AS-C sticker 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 / +70 °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.
