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

Acid Coil Cleaner leaves the aluminum surface clean and shining bright

Improper refrigerant levels, dirty coils, and worn out compressors or condensers can result in inefficient performance of air conditioning system. An inefficient system tends to force the compressor to work harder than is required decreasing its life span and thereby leading to higher energy bills. The primary energy required in operating an air conditioning system comes from the compression of refrigerant. The hotter the compressor receives the processed refrigerant, the more energy is necessary to force it through the condenser. The refrigerant needs to become cold enough to absorb more heat from the process, therefore an external chiller such as an open evaporative condenser or air blast unit is required. It is crucial for effective air-conditioning operation that the condenser is able to easily reject heat through the cooling airflow and the heat exchanger coils. Energy consumption builds up as the refrigerant vapor pressure increases, where the refrigerant is not sufficien...

How RO Antiscalant works?

  Reverse Osmosis technology provides an efficient and reliable method for purifying water for various purposes). It can remove impurities such as salts, minerals, and other contaminants as well as microbial contaminants from the Membrane. Water molecules pass through RO membranes despite dissolved solids and other contaminants being rejected by the membrane. RO membranes are basically thin, dense, and semi-permeable membranes. However, the major significant challenge in Reverse Osmosis System is Scaling. Why does it happen? The formation of scales on the RO (Reverse Osmosis) membrane is primarily caused by the presence of certain dissolved minerals and salts in feed water. Scale refers to the accumulation of mineral deposits, such as calcium carbonate, calcium sulphate, and silica which can severely impact the efficiency and the lifespan of the RO membrane. RO Membrane scaling may lead to cause ·          Excessive Energy Consumption...
