TONO FROST 593: The Ultimate NSF-Certified Solution for Food & Beverage Heat Transfer

In the world of food and beverage processing, maintaining thermal efficiency, ensuring product safety, and minimizing operational downtime are all non-negotiable demands. Whether it’s for cold storage, chilling equipment, pasteurization lines, or fermentation control, the choice of heat transfer fluid can significantly impact both performance and compliance.

TONO FROST 593, developed by Chemtex, is an NSF HT1-certified inhibited propylene glycol solution engineered to meet the highest standards of safety, performance, and efficiency in food-grade environments.

What is TONO FROST 593 ? TONO FROST 593 is a blend of food-grade propylene glycol and a corrosion inhibitor package designed to provide:

  • Long-lasting protection against rust, scale, and corrosion

  • Stable thermal conductivity

  • Wide temperature operability

  • Food safety compliance for indirect contact

In a market flooded with products, NSF certification stands as illumination of reliability and trust. Unlike many pre-inhibited glycols, TONO FROST 593 retains freeze protection, even in extreme low temperatures, while ensuring zero compromise on safety or performance.



What Does TONO FROST 593 Offer to the Industry?

In applications where temperature-sensitive environments are paramount, poor-quality or improperly inhibited glycol-based fluids can create major problems such as metal corrosion, system inefficiency, unexpected breakdowns, and high maintenance costs.

Rely upon these advantages

  • Saves Power: Heat transfer systems lose efficiency as glycol degrades or sludge builds up. TONO FROST 593 maintains an optimal heat transfer rate, ensuring chillers, pumps, and compressors aren’t overworked—leading to significant energy savings.

  • Protects Metallurgy:  It protects metals like Stainless Steel, Copper, Brass, Aluminum, Cast Iron. This helps to prevent system failure due to pitting, leakages, or scaling, reducing repair costs and increasing uptime.

  • Maintains Freeze Protection: Ensures uninterrupted protection in sub-zero applications, making it ideal for frozen food storage, chilled water systems, and brewery fermentation cooling.

Why Make the Switch?

The most important aspects are

  • Safety: Compliant with international food safety standards

  • Low Maintenance: Protects metallurgy and reduces downtime

  • Eco-Friendly: Non-toxic, biodegradable, and sustainable

  • Cost-Effective: Reduces energy bills and long-term repairs

Make the switch to TONO FROST 593—where thermal efficiency meets food safety

Replacing Sodium Hypochlorite with Double Chain QAC based Disinfectant

Replacing Sodium Hypochlorite with Double Chain QAC based Disinfectant Remember that pungent smell when mass disinfection of public places occurs. That same irritating smell you can relate to in swimming pools, and your eyes itch and redden, and your skin itches, and there is a big board saying “Chlorine in pool”, that’s hypochlorous acid, viz., when sodium hypochlorite breaks down. Sodium hypochlorite/ Hypo (NaOCl) is inorganic chlorine based liquid disinfectant, available as aqueous solutions of 5.25% - 6.15% (household bleach) or concentrated 12% NaOCl solutions. Large quantities are also used as a disinfectant in water and wastewater treatment and sanitary equipment. In food processing, sodium hypochlorite is used to sanitize food preparation equipment, in fruit and vegetable processing, mushroom production, hog, beef and poultry production, and fish processing. Typical Uses of Hypo: ·       2%: Shock Chlorination of Wells · ...

Role of Polyelectrolytes in Wastewater Treatment

  Effluent Treatment or Industrial wastewater treatment consists of mechanisms and processes which are used to treat water that have been contaminated by anthropogenic, industrial or commercial activities prior to its release into the environment. Industrial wastewater serves as one of the important pollution sources that add up in polluting the water environment. The sewage sludge produced is subjected to sludge treatment. Many problems are associated with wastewater collection and treatment such as foaming, solid accumulation, high BOD, sludge de-watering, heavy metals and offensive odour.   But such treatments are no more complicated processes, since there are chemicals that are applicable for the treatment. These chemicals follow various treatment mechanisms in various different standards, which include from chemically treating raw wastewater before discharging it into the environment, to recovering valuable resources from sludge treatment and wastewater. Conventional tr...

The Role and Importance of Demulsifiers in Oil and Gas Industry

  Demulsifier helps to extract oil and purify water, which is especially important in crude oil production and wastewater treatment.   It is a substance that separates an emulsion into components and destabilizes water-in-oil emulsions. In Crude production, Water-in-oil emulsions are typically produced, owing to the presence of emulsifying agents such as surfactants, slits, fine solids, drilling mud, clay, water, and other impurities. These impurities are undesirable need to be removed which would otherwise shackle the quality of the crude.   How does It work? Demulsifier consists of two liquids that are not mixed with each other and tiny droplets of one liquid are evenly distributed throughout the volume of the other. This kind of liquid is called dispersion medium, and the droplets are called dispersed phase. During the demulsification process, a demulsifier accumulates on the surface of the droplets and groups them together.   The process of separating a...
