Upstream Systems

Upstream® systems are engineered to achieve the same performance standards as NSF 55 Class A certified Halletts, but are for use where regulations do not require it that certification. Because Crossfire Technology is so powerful and efficient, there are Upstream models for surface and dug well water use where UVT levels are as low as 50%.

Upstream systems include flexible stainless steel hook-up hoses, and a Transient Voltage Surge Protector as standard. Auto shut-off solenoid valves and wireless remote monitors are options.

Why Upstream™?

  • Laboratory tested to 40 mJ/cm2 dose at END of lamp life — same as NSF/ANS55 Class A certification. Competing brands test at beginning at lamp life and at a potentially unsafe dose of only 30 mJ/cm2.
  • Tested at 50% and 75% UVT (UV transmittance) of water. Competing brands test at virtually pure 95% UVT.
  • Operates at a wide range of water and air temperatures and pre-treatment ranges, unlike competing brands with limited operating conditions.
