Simple solutions to complex problems

While ATI’s sleek, sophisticated products use advanced engineering to ensure outstanding performance, they are also very easy to use. For example, our popular SunPower T5 lighting fixtures are plug & play; Essentials Pro is a comprehensive water care system that provides 28 essentials elements in a simple, 2-part solution; and ATI Labs ICP-OES water analysis tests your water and RO for over 40 parameters at the same time.


ATI products are more affordable than you might realize and offer good price/performance ratios. Compared to similar offerings, you will find our products are competitively-priced and outperform the competition.
