The WAVE SL990
freeze drying 2.0
The SL990, the larger version of the SL770 is the second machine of a completely
new series of freeze drying machines.
We re thought freeze drying from the bottom up for this new model.
Every piece of the SL990 is made to
improve productivity, save time and energy.
Fastest extraction capacity
The SL990 uses a completely new type of coldtrap, The SL990 Coldtrap moves right next to the material, reducing the travel of vapour to a minimum and increading the extraction time to the absolute minimum.
Fastest deicing
No other method reaches our deicing speeds, we took deicing of a capacity of up to 220 Kg from a usual 5 hrs to 20 minutes. Using a hot gas bypass and electric heating the coldtrap heats up very fast, the ice then falls of the coldtrap and after a short time the next batch can be loaded.
Fastest reloading
While the machine is deicing you can already charge the machine with the next batch of material.
Shockfroster included
Below the drawers unit the machine houses a shockfroster unit for all of the 72 trays which are 400 x 600 mm (european standard), while the machine is drying one batch it already freezes the next one.
Complete new design
The sliding door enables to load the machine from the side and avoids using sticks or huge chambers usually necessary to access tablets in such large machines. Another advantage is that we have completely eliminated all cables from the chamber.
The icebox saving 40% of energy
The sink below the drawers unit is used to catch the ice as soon as it unsticks from the coldtrap, from here it falls to the icebox on the lower side of the machine.The ice is then used to cool the refrigerant for the next batch saving up to 40% of energy of a run, more than silicon oil based machines can save.
Handheld HMI
The unit is equiped with a handheld HMI and can also be accessed remotely, no need to run over to the machine to see what is going on, take the HMI with you.
When the machine is working and the unit is closed, the sind can be used as a workplace to prepare the material for the next batch and place it to the shockfroster, another advantage and time saving feature.
YES it moves and its transparent !
The chamber itself is moveable to make way for the melting ice when it falls down, also it is really transparent acrylic glass, this way you can actually watch the material as well as the ice build up as it happens.
The SLS990 is the larger version of the SL770, with a tray area of 18m2 and an extraction capacity of 220Kg, it manages up to 50% more power than its smaller brother.
The SL990 uses industrial vacuum technology, it uses only top brnded material such as a Blitzer compressor, Siemens controler, Leantech rails, Edwards pumps and more, the device is manufactured in our factory in Vienna.
Wave has its headquarters in Austria. We supply and support customers throughout Europe. The SL990 is equipped with remote maintenance. Spare parts are always available.
We also have a service center in the US that serves our US customers.
The SL990 features a completely new design and approach to freeze drying. The drawers can be accessed from the side, the lower part of the machine is a shockfroster, you can quickly load from the shockfroster to the machine without losing time. Defrosting is faster and cleaner than on any other machine and the ice is reused to save energy on the next batch.
Our goal is to offer the best price-performance ratio for freezedryers. Price on request - a leasing with one of our partners is also available.
The SL990 uses a sliding transparent vacuum chamber to make way to collect the ice and to make use of it for the next batch of production reducing energy usage up to 40%.

The SL990 uses the lifgo railsystem to move the chamber and drawers unit along the chassis.
The lower unit houses a shockfroster that can store all
72 drawers. Once the machine is defrosted it can be quickly loaded with the frozen goods and the next batch can be produced.
A strong Blitzer compressor enables the SL990 with
up to 220 Kg of extraction capacity.
A completely new approach to freeze drying enables fastest turnarrond ever in the industry; loading from the side avoids using sticks to access trays deep inside a tube; the sink drawers unit does not touch the wall and enables maximum capacity for ice.
When the machine is drying, the left part serves as a workbench to prepare the next batch that can be prefrozen in the included shockfroster.
After the drying process the chamber moves away from the coldtrap and quickly releases the ice that is reused to cool the compressor for the next batch.
