We are running a ~600 ton, Frick screw, flooded 2 stage ammonia system in hong kong.
Last week a sales man came to me and the manager to explain the significent financial savings of adding PermaFrost (.permafrostonline.com) into our system.
I have never been a believer of the "magic pill" as they normally do more damage than good.
Has anyone used this product? what does it do to to your plant.. any long term damage? or is it really all they say
Is it really going to mean I can run fewer screws more of the time? and cut my running costs by 20%?
I am after some real data(not pimped from one of the many PermaFrost websites) to advise my boss so he dosent make a big mistake that I have to clean up later.

Thanks
