Genuine Niagara No-Frost and Hygrol liquids

  • Niagara No-Frost LV-2 Liquid contains a blue dye for identification.  No-Frost LV-2 has a lower viscosity at low temperatures, and thus is used in systems that require operation at temperatures below 0oF (-18oC).
  • Niagara No-Frost KV Liquid is typically used at room temperatures above 0oF (-18oC) and is used for controlling the relationship between the dry bulb and dew point temperature.  KV is also blue in color.
  • Niagara Hygrol Liquid is a yellow-dyed liquid predominantly for controlling air humidity.  Hygrol liquid relies on its hygroscopic nature to absorb water from an air stream into which the Hygrol is sprayed.  Hygrol is a stable, non-corrosive liquid.
  • Niagara Clearfrost Liquids are additives used help maintain system stability.  There are several variations of Clearfrost available with uses including: corrosion inhibitor, foam depressant, alkalinity booster, and bacteriocide.
