Upsite Technologies Testimonials

"Ongoing optimization of our IT infrastructure is the be-all and end-all for us. Thanks to KoldLok we saved more than €46,000 in electricity costs this year and achieved a full return on our investment in a period of only three months."

“After having hands on experience with nearly every available product on the market, HotLok is by far the superior choice. Not only does it create the best seal, but its universal mounting system and finger grips make it the easiest to use and reuse.”
