Alpha condenses in its own name etymology the meaning of a new beginning, the very first letter representing at the same time the DNA dominant factor in the market arena, what we confidently expect this outstanding and innovative product will be for the next decade and hopefully more.

At IWT, as part of the Tecniplast group, for the past 30 years we have been engineering and manufacturing with relentless efforts and passion cage and rack washers as the core and central activity of our organization and by now we can proudly say that we installed close to 1100 RW units in Lab Animal facilities all around the world, from Canada to New Zealand, from Siberia to Brazil… a very tangible sign of constant commitment, persistent focus and great product ideas, then well executed!

The founding pillars of this great journey have always been 3 in our minds: first outstanding validated cage throughput, combined (and this is the difficult part!) with increasing energy efficiency and remarkable flexibility, for the buildings as well as for the users!

Now I can tell that the Alpha RW, along the line of its glorious predecessor models, the 700 series, the 900WP/GP and the current Atlantis family, will take these pillars to the next and unprecedented level.

“Having seen the new RW Alpha Rack and Cage Washer during its launch at the FELASA Congress, I was impressed by the new improved washing motion which allows a greater wash capacity, and the new presentation rack design makes loading of difficult items, such as food hoppers, enrichment items and lids, easy and efficient. I think the RW Alpha Rack and Cage Washer is awesome.”


Carla Smith, Bioresources Manager, Telethon Kids Institute, Perth Western Australia

“I recently attended the FELASA Congress and was able to be at the launch of the new RW Alpha Rack and Cage Washer from IWT.  Some of the features that really excited me about the RW Alpha Washer include the Emergency Rope that replaces the emergency bar, what a fantastic idea, and what this means is no more accidental leaning on the emergency release bars when loading or unloading the chamber. 

Also, this smart idea takes up less space, which means the washer has greater washing capacity! The reduced door weight, the easier close / engage function of the door and pop out gasket are other features that will increase the ease of use and minimise push-pull forces, making washroom operations less difficult.

I was amazed by the new floor layout, which once again is more user friendly, overall, IWT have created a new Rack and Cage Washer that functions as well (if not better) than the ‘gold standard’ Atlantis Rack and Cage Washer and which incorporates many ergonomic features that make washing quicker, simpler, easier and more efficacious.”
