Product Description

Tono Frost 593 is a pre-inhibited propylene glycol, used as an industrial coolant, antifreeze heat transfer agent. The inhibitor package is designed to protect brass, copper, solder, steel, cast iron, aluminium and other metals commonly found in industrial cooling and heating systems.

The effectiveness of Tono Frost 593 in preventing corrosion has been proven in extensive laboratory and in actual service tests. Using TONO FROST 593 for heat transfer applications instead of brine solutions or uninhibited propylene glycol reduces maintenance costs and improves heat transfer efficiency and equipment life.

Product Highlights

Freeze Protection Volume

Tono Frost 593 helps save upto 2-4% against normal propylene glycol quantity required for desired freeze protection.

Corrosion Control
Corrosion Control

Tono Frost 593 does not oxidize to form highly corrosive organic acids and thereby do not lead to corrosion of metal, pitting, pinhole and stress cracking.

No Bio Fouling
No Bio Fouling

Tono Frost 593 protects water based HVAC systems from freezing, corrosion and bio-fouling.

Key Features and Benefits

  • Pre-Inhibited for corrosion prevention
  • NAP (Nitrite Amine Phosphate) free
  • Extended Life Coolant (ELC)
  • Added preservatives for longer shelf life
  • Compatible with hoses and rubber fittings
  • Does not scale with hard water
  • Non-toxic for F&B applications
  • Eliminates need for SCA (Supplemental Coolant Additive)
  • Does not contain silicates which causes aluminium heat rejection losses
  • Non foaming nature – reduces nucleate and hot spot boiling

How To Use

Old System

Un-inhibited brine or glycol must be descaled online/offline and passivated prior to dosing of Tono Frost 593.
Contact your nearest CSL Representative to dilution recommendations.

New System

Prior to addition of Tono Frost 593, a thorough pressure test must be completed. New systems contain many impurities and foreign matter like dirt, grease, soldering deposits and can degrade properties of coolant. It is important to clean and passivate the system.
