FreezeSafe

FreezeSafe is a reliable, single-use freeze temperature indicator designed to protect temperature-sensitive goods during storage and transit. Offering irreversible visual evidence, FreezeSafe ensures instant detection of exposure to unacceptably low temperatures, making it ideal for pharmaceuticals, biologics, vaccines, and food products.

When temperatures fall below the pre-set threshold, FreezeSafe changes color permanently from clear to magenta, providing an immediate accept/reject decision point for quality assurance teams. This simple yet powerful solution helps logistics operators and supply chain professionals prevent the distribution of compromised goods.

Each indicator supports full traceability with serialized batch numbers, strengthening compliance with cold chain management standards. FreezeSafe is a cost-effective safeguard against freeze damage, ensuring your shipments remain safe, effective, and compliant from manufacturer to end-user. Trusted worldwide, it’s an essential tool for reducing product loss and ensuring regulatory compliance across South Africa’s pharmaceutical and food industries.
