A wide variety of other applications that require mitigating condensation within enclosures

ACTIVE-S PRODUCT INFORMATION

Only Active-S Controls Humidity by Absorbing and Releasing

The Active-S "Humidity Control Sheet" is a highly effective equipment maintenance product that prevents condensation, utilizing a special active fabric developed for a major Japanese telecommunications provider.

Active-S is not a desiccant Active-S Humidity Control Sheets are made of a macromolecule polymer, which is a super-absorbent material that "breathes," providing an active exchange of absorption and release. When humidity in the enclosure is high, the humidity control sheet absorbs the excess moisture, reducing humidity levels inside the cabinet. But when the cabinet becomes dry, the sheet "breathes out" the moisture, maintaining relative humidity at under 60% in the cabinet at all times.

View Active-S Presentation

Consistently maintains humidity level at or under 60% by absorbing and releasing moisture in the air
Fits any size enclosure, even tight spaces and curved surfaces
Requires no space, no maintenance, no power source
Long usage life - 10 years of proven field testing
Significantly reduces time and labor costs
Installs with double-sided tape, Velcro or magnetic tape
No moving parts to fail
Four sizes to suit enclosure capacity
Lowest applied cost

Simplify your Design, Lower your Cost

Conventional desiccants do not perform well after absorbing certain amount of moisture. ehumidifiers and hygrostats take up space and require power. No need for that anymore. The superior breathing characteristic of Active-S Humidity Control Sheets maintain high performance over a long period of time.

Simplified installation
No need for maintenance
High performance over a long period of time
Time and labor costs are significantly reduced
Lowest cost solution for controlling humidity

There are four different sizes to choose from to suit the capacity of the enclosures.

Calculate Active-S Size for Your Requirement

measure enclosure inside dimensions
Width(W) x Depth(D) x Height(H) = Cubic inches

Example 1:
Interior dimensions of cabinet: 20” Wide x 18” Deep x 24” High
Volume: 20 x 18 x 24 = 8,640 cubic inches
From the table, one AS-M will do up to 9,154 cubic inches

Example 2:
Interior dimensions of cabinet: 18.5” Wide x 14” Deep x 24” High
Volume: 18.5 x 14 x 24 = 6,216 cubic inches
From the table, one AS-M will do up to 9,154 cubic inches but 14.6” width of AS-M is greater than 14” depth of cabinet so to install sheet on side surface use 4 of the AS-P sheets

Precautions for Use

Take adequate measures to keep water out of cabinets before installing Humidity Control Sheet
The standard application is intended for use in a sealed space.Changes in usage environments may affect results.
