Frequently Asked Question

What is CFHN21 and what makes it special?

CFHN21 is a corrosion-free phase change material built from a blend of organic and inorganic components. It’s engineered to operate at sub-zero / frozen temperature ranges, intended for deep freezers, vaccine carriers (Freeze-On-Wheels), frozen food transport, and ice cream logistics.
Its key advantage: it remains non-corrosive, even in contact with metal surfaces, making it safer for direct use inside metal containers or systems.

It is designed to sustain low, sub-zero temperatures (frozen regime) in challenging ambient conditions, acting as an alternative to ice in mobile or stationary cold systems.

The holdover duration depends on factors such as ambient temperature, insulation quality, packaging design, and thermal load (mass of goods). You should test in your specific container and route to get realistic estimates.

Yes — CFHN21 is made for repeated thermal cycles. It retains performance through many cycles if handled properly.

You need to bring it to its frozen or solid state (i.e. pre-freeze it) under controlled conditions (deep freezer or cold chamber) before packing, so it can function properly during transport.
