Customer Testimonials

Guardian Manufacturing customers, Columbia Valley Fruits, First Fruits / Broetje Orchards, are pleased with the overall operation, reliability and delivery ozone for aqueous ozone applications. Watch Steve King, Quality Control Manager at Columbia Valley Fruits and Bob Franklin, Manager for Broetje Orchads discuss their experiences and overall benefits of Guardian's Ensure-ATS aqueoous ozone systems.

"The cost of ozone compared to former chlorine dioxide we used is much lower and again the byproduct being just water" states Steve King.

"With organics, we are extremely limited to what we can do in the orchard and also in storage.  Unlike in conventional fruit where we can use fungicides and anti oxidants, we are not allowed to do that with organics. Ozone fits that area very nicely," states Bob Franklin.
