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.
