High-Performance 15–25°C CRT Packs for Reliable Thermal Packaging

  • Maintaining a strict temperature range between 15°C and 25°C—known across industries as Controlled Room Temperature (CRT)—is one of the most challenging aspects of modern cold chain logistics. Unlike frozen or deep-chill shipping, CRT applications require thermal packaging that can both absorb ambient heat on hot summer days and release heat during freezing winter transits.

  • At PCMCOOL, we specialize in manufacturing premium 15–25°C Controlled Room Temperature Packs designed to bridge this gap. Utilizing our advanced, high-latent-heat phase change materials (PCMs), these thermal packs act as an automatic thermal buffer. They ensure your high-value, temperature-sensitive cargo remains perfectly stabilized within the 15–25°C threshold, regardless of unpredictable external weather conditions during global transit.

Why Choose Our Phase Change CRT Pack Solutions?

When transporting pharmaceuticals, biologics, or luxury goods, standard water-based gel packs are entirely ineffective for CRT parameters because they freeze at 0°C and melt too quickly. Our specialized phase change material packs offer engineered thermal precision.

The Technology Behind 15–25°C CRT Packs

Our 15–25°C Controlled Room Temperature (CRT) Packs are formulated using eco-friendly organic phase change materials with a precise thermal transition point centered exactly at 20°C. 

When ambient temperatures rise toward 25°C, the pack absorbs the excess heat by transitioning from a solid to a liquid state. Conversely, if ambient temperatures drop toward 15°C or below, the pack releases stored latent heat, preventing the payload from freezing. This dual-action thermal regulation provides unparalleled cargo protection.

Pharmaceutical & Vaccine Logistics

A vast majority of modern small-molecule drugs, pills, and specialized medical medical devices mandate strict room-temperature storage. Exposure to extreme heat degrades chemical stability, while cold shock can compromise liquid formulations. Our Controlled Room Temperature CRT Packs are the trusted choice for pharmaceutical freight forwarders executing international distribution.
