CFHN21 | Corrosion Free Phase Change Material
CFHN21 is a specialized pcm designed from a blend of organic and inorganic components. Engineered to perform at sub-zero temperatures, this corrosion-resistant material is ideal for use in environments requiring reliable cold storage, such as deep freezers, vaccine carriers (FOWs), frozen foods, and ice cream transportation.
Thanks to its unique formulation, PCM CFHN21 offers an efficient and eco-friendly alternative to traditional ice, particularly in mobile or stationary temperature-controlled systems. It maintains a consistent low-temperature range over extended periods, even under challenging ambient conditions. Additionally, its non-corrosive nature ensures safe, direct contact with metal surfaces, making it a practical solution for various cold chain logistics applications.

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.
What temperature range / application does CFHN21 target?
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.
How long can CFHN21 maintain frozen / sub-zero temperatures in transit or storage?
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.
Is CFHN21 reusable / can it be recharged?
Yes — CFHN21 is made for repeated thermal cycles. It retains performance through many cycles if handled properly.
How do I “charge” or precondition CFHN21 before use?
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.
