THE FUTURE OF I G DESICCANTS

.

NEDEX PSgirlWhen Zeolite-based molecular sieve desiccants were first developed for use in insulating glass, they were just about as good as it could get. The whole concept of being able to selectively adsorb some vapours but not others was quite unique. Gas filling of units was on the increase, and the ability to grab water vapour but leave other gas molecules alone was tremendous. Earlier unit constructions contained crude desiccants like silica gel, or blends with 10 Angstrom desiccants.

.

These were designed to deal with solvent vapour and thereby prevent chemical fogging, a kind of rainbow condensation on the inside unit surface, because volatile solvents were often used to regulate the viscosity of sealant back then. But as well as dealing with those volatiles, they would also adsorb argon gas, causing under-pressure in the sealed unit cavity and distortion of the glass.

.

The advent of solvent-free sealant and selective molecular sieve desiccants meant that 3-Angstrom desiccant could be used to efficiently adsorb water vapour while the larger molecules of argon were not affected. At the same time, problems of units ‘pumping’ and putting unnecessary stress on the perimeter seal due to nitrogen being adsorbed and desorbed, over and over again as temperatures shifted, was virtually eliminated. A great bonus for users of hot sealants in particular.

.

But times move on, progress does not stop, and now there is a whole new generation of desiccant specifically designed for use in insulating glass.

.

World leaders in this field, Nedex Group, have refined a method that combines Zeolites with selected non-zeolite minerals. These are activated in a special process so that only water vapour is adsorbed but not argon or other gases, and to such an efficient degree that the available adsorption capacity is over 30% higher than all Desiccant Plantknown zeolite-based alternatives.

.

An independent test by TNO confirms capacities up to 28% where manufacturers of industry standard zeolite sieves generally claim between 18% and 20%.

.

Delta-T activity is high, typically 40 to 50oC. Gas desorption levels are tiny, well under half that specified by test regulations. And all deployed minerals are inert and harmless.

.

Environmentally far more friendly too, NANOMOL is manufactured entirely from natural mined substances, whereas separation of aluminium-bearing minerals from bauxite for the production of 1 tonne of zeolites can result in generation of up to 4 tonnes of caustic slurry heavy in iron and sodium hydroxide.

.

With all these advantages, you’d expect to see a high price tag on NANOMOL. In fact the opposite is true as Nedex owns and controls all processes from mining the raw minerals through to the finished product.

.

Warning: There have always been alternative desiccants from other industries like concrete processing. Many contain low-cost general absorbents like Calcium Chloride (CaCl)  which are caustic and will chemically react with moisture and become powdery and acidic. These are not properly suited to I G manufacture, and operators must be protected from contact with moist skin, eyes and lungs.

.

Members of the Nedex team were able to film operatives in one factory in China last year, adding Palygorskite to their mix to reduce weight and density of their desiccant, a lightweight fibrous mineral that is dangerously close to asbestos.

.

NANOMOL is none of these. Specially formulated and processed in unique equipment designed by experts over a three year period, it is safe, friendly, and puts a very big tick in all the boxes.
Adsorption capacity, Gas desorption, Delta-T activity, Health & Safety, Environment …and Cost.

.

Already more than 350 tonnes a week are rolling out of the Nedex plant headed for major I G plants worldwide, in cartons, metal drums and BigBags.
