Phase Change Material IN19 | For Deep Freezer & Frozen Food Transport
IN19 is a specially formulated inorganic material that changes phase at sub-zero temperatures without causing corrosion. It is well-suited for use in low-temperature settings such as deep freezers and Freeze-On-Wheels (FOWs). As a practical substitute for traditional ice, PCM IN19 ensures stable and long-lasting cooling for both stationary and mobile cold storage systems. It performs reliably even in extreme ambient temperatures, making it an effective choice for maintaining cold chain integrity.

Frequently Asked Question
What is PCM IN19 and what is its primary application?
PCM IN19 is a sub-zero inorganic phase change material specially formulated to maintain very low temperatures without causing corrosion. It’s ideal for deep freezers, mobile freezer units (Freeze-On-Wheels), and frozen food transport systems.
How long can IN19 keep things frozen or maintain the required low temperature?
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut elit tellus, luctus nec ullamcorper mattis, pulvinar dapibus The “holdover time” depends on multiple factors: ambient temperature, insulation, internal heat load (mass of goods), and how well IN19 is preconditioned (frozen) before use. You should test it in your specific setup to know real performance.leo.
In what forms or packaging is IN19 offered?
IN19 is available in formats like pouches and bottles, allowing flexibility in designing shipping containers or cold storage systems.
How long can IN19 keep things frozen or maintain the required low temperature?
The “holdover time” depends on multiple factors: ambient temperature, insulation, internal heat load (mass of goods), and how well IN19 is preconditioned (frozen) before use. You should test it in your specific setup to know real performance.
Is IN19 reusable or rechargeable?
Yes — IN19 is meant for repeated phase change cycles while retaining performance. Its durability depends on operating conditions, temperature extremes, and handling.
