🖼️ Behind every masterpiece is a carefully controlled environment.

In galleries, museums, and archival storages around the world, quiet systems work around the clock to protect history. One of the most crucial elements in this effort is something rarely noticed: humidity control.

Fluctuations in humidity can cause irreversible damage — warped canvases, cracked book bindings, even the growth of mould and microorganisms on fragile materials. While air conditioning plays a role, it often leads to overcooling and energy waste, without addressing the core issue.

For instance Canberra museum and art gallery had consistently struggled to achieve the humidity levels required for the long term preservation of art works. Desiccant ventilation was found to be a viable option without consuming excessive energy while still being able to achieve 50% RH, Two DST 102L desiccant dehumidifier rotors were selected and installed into a system The system controls the humidity in the gallery to 50%RH +/- 1.5%RH at 230C.

This stability ensures the art of Sidney Noland is stabilised for future generations to enjoy and protects their substantial value (Worth more than the building)!

Desiccant dehumidifiers offer a precise solution 👩‍🎨 :

-Humidity control independent of air conditioning
-Reduced energy use — no overcool/reheat cycles
-Hot water (including solar) can be used for sustainable dehumidification
-Stable, consistent climates ideal for preserving artworks, books, and microfilm

Institutions across the globe — from the Library of Alexandria in Egypt to the Imperial War Museum of the UK — have relied on these systems to protect collections for future generations.

Preservation isn’t only about what’s seen — it’s also about what’s carefully maintained behind the scenes.

❄️Achieving Low Dewpoints with Leading Japanese Technology🗾

Seibu Giken, now in its 60th year, continues to lead the way in desiccant rotor innovation for all types of relative humidity control.

One of the most demanding challenges? Preventing ice formation in -40°C freezer environments. That’s where the DST RLZ series excels — delivering reliable, low dewpoint performance down to -50°C with minimal modification.

👉Why does this matter?

In food processing, any air infiltration into a -40°C space can cause frost, delays, scanner failures, and even safety risks from slippery surfaces. With properly dried air:

-No frost forms
-Existing ice sublimates
-Production stays efficient and safe

The RLZ104 unit is currently supplying ultra-dry air to a plate freezer for meat cartons, achieving dewpoints of -50°C. For faster deployment, the RLZ82 hits -40°C dewpoint with a standard setup and a 5°C pre-cooler.

✅Also ideal for:

-Loading docks
-Freezer door condensation control
-Energy savings

📲 Let’s talk if you’re facing RH challenges in low-temp environments. We have the solution.

Seibu Giken was the first company to develop a Silica-gel rotor and it is used in all DST desiccant dehumidifiers.

The silica gel is chemically bonded to the rotor, which means that there is no desiccant carry-over to the air. It also means an excellent lifetime. After 10 years of operation, the Seibu Giken rotor retains more than 90% of its original capacity.

Another important feature of the silica gel bond on our rotors is that it can be washed if it becomes contaminated.
This is especially important for rotors working under harsh conditions!

Recently we have been lucky enough to assist National Archives all across Australia with humidity control. This is significant for these facilities as preservation and maintenance is essential for the 40 million+ items of national memories that are exhibited online and in person.

In 2012, National Archives in Villawood had DST model RA061R installed which has since proven to be efficient and reliable with no component replaced in its first 8 years other than standard filter replacements.

DST also provided mold remediation equipment when an infestation of unconditioned stocks was identified.

DST has since assisted the National archived of Darwin with two RL071R models which are larger versions of the unit that provide humidification and significantly decreases the change of mold.

With over 800,000 rotors delivered DST’s Seibu Giken of Japan are the world leader of rotor technology.

Seibu Giken invented the use of stable desiccant silica gel in rotors in the 1980s which has allowed the use of desiccants in high efficiency commercial applications.

A storm water pipe burst in the ceiling of Mounties RSL Club NSW flooding the gaming room and foyer. One of our largest desiccant units was installed in non-trading hours of 3am-9am with Riverwall Constructions & Restorations.
No loss of trading and a very happy client. Success!
