PROPYLENEGLYCOL COOLANTS «NORDWAY PRO»
- intended for use in various systems with operating temperatures from +90°С to –33°С
«Nordway-PRO» is a high quality heat transfer liquid/coolant based on monoethyleneglycol used for various types of cooling equipment.
Depending on the concentration the “Nordway-PRO” water mixture can be cooled down to –30°С.
Recommendations: application in refrigeration systems characterized by operating temperatures down to –33°С and as a concentrate for other.
OPERATIONAL BENEFITS
Anticorrosive protection. Considering the lack of normative documentation for refrigerants and cooling liquids, all data on corrosion protection was obtained according to GOST 28084 which was developed for evaluation of automotive anti-freeze additives, which are used at high temperatures and in systems which differ significantly from refrigeration systems by used metals and their interplacement methods. Refrigerants are applied at negative temperatures, at which corrosion processes are repeatedly slowed down.
ECOLOGICAL ADVANTAGES
The safest products which meet requirements for the impact on materials and environment include coolants based on propylene glycol and acetates, which solutions belong to Class 4 (low hazard products). Propyleneglycol has been widely used in cosmetic and pharmacological industries, as well as in the food industry in the form of approved food additives.
