What temperature is required for storing mRNA vaccines?

mRNA vaccines require ultra-low temperature storage between -70°C and -80°C. WinHyCare ultra-low freezers operate from -40°C to -86°C, providing the precise cold chain conditions needed. Our dual system models offer backup redundancy — if one compressor fails, the second maintains -70°C, ensuring vaccine safety.

Which WinHyCare freezers are suitable for vaccine cold chain programmes?

For mRNA vaccines: our ULT freezers (WDF-86V series from 188L to 838L). For live attenuated vaccines: our -40°C medical freezer (WDF-40V528). For routine vaccines (2-8°C): our blood bank refrigerators (WBC-4V series from 108L to 1008L). For transport: our mobile coolers (WDF-25H series) with multi-voltage support.

How do WinHyCare freezers maintain temperature during power outages?

Our blood bank refrigerators include 72-hour backup batteries for alarms and display. Ultra-low freezers feature VIP insulation panels that maintain temperature stability during brief outages, plus power failure alarms with remote contacts for immediate notification. We recommend connecting to UPS/generator systems for critical vaccine storage.

Do WinHyCare products support cold chain documentation and audit trails?

Yes. All our units feature USB data ports for downloading temperature records. Our blood bank refrigerators include standard thermal printers for automated temperature logging. Digital displays with 0.1°C resolution provide real-time monitoring, and remote alarm contacts enable integration with facility-wide monitoring systems.

Can WinHyCare mobile coolers transport vaccines from warehouse to vaccination sites?

Yes. Our mobile coolers are actively refrigerated (not passive ice-pack coolers), providing continuous cold chain maintenance during transport. They operate on AC 220V, AC 110V, or DC 12V vehicle power, and support three temperature modes: 2-8°C, -10°C to -25°C, and 22±2°C to cover all vaccine transport requirements.

What certifications do WinHyCare vaccine storage products hold?

All WinHyCare products are manufactured under ISO 9001 (quality management), ISO 13485 (medical devices), and ISO 14001 (environmental management) systems. Our equipment supports compliance with WHO, UNICEF, and national vaccine storage guidelines.

What is the largest capacity vaccine cold storage unit WinHyCare offers?

Our largest ultra-low freezer is the WDF-86V838 series at 838L — available in dual system, cascade, and self-cascade variants. For 2-8°C storage, the WBC-4V1008 offers 1008L capacity. Both are designed for regional distribution centres and large hospital pharmacies managing significant vaccine inventories.

Vaccine Cold Chain Solutions — Ultra-Low Freezers & Transport

Ultra-Low Temperature Vaccine Storage (-86°C)

mRNA-based vaccines such as those developed for COVID-19 require storage at ultra-low temperatures of -70°C to -80°C. WinHyCare ultra-low temperature freezers provide the precise, reliable cold storage these next-generation vaccines demand. Our ULT freezers range from 188L to 838L capacity, offering dual system, cascade, and self-cascade refrigeration technologies. Each unit features a 7-inch LCD touch screen, microprocessor-controlled temperature management with 1°C increment precision, and comprehensive alarm systems including high/low temperature, power failure, door ajar, and sensor failure alerts. With VIP insulation panels and CFC-free HC refrigerant achieving up to 50% energy savings, these freezers deliver both performance and sustainability for vaccine storage programmes.

Deep Cold Vaccine Preservation (-25°C to -40°C)

Live attenuated vaccines and certain mRNA formulations require long-term storage below -20°C. WinHyCare's -40°C medical freezer (WDF-40V528) provides microprocessor-controlled forced-air cooling with 0.1°C resolution digital display, ensuring your vaccine inventory remains at the precise temperature required. The 528L capacity is ideal for regional distribution centres and hospital pharmacies managing large vaccine stocks. Built-in alarm systems — including high/low temperature, power failure, door ajar, and sensor failure alerts — provide multi-layered protection. Password-protected controls prevent unauthorized temperature changes, while adjustable shelves and interior lighting ensure efficient daily operations.

Standard Cold Storage for Vaccines (2-8°C)

The majority of routine immunization vaccines — including inactivated, subunit, and toxoid vaccines — must be stored between 2°C and 8°C. WinHyCare blood bank refrigerators are engineered with forced-air cooling and electrical heat compensation to maintain a consistent 4±1°C, making them ideal for vaccine pharmacies. Our units feature 72-hour backup battery systems that keep displays and alarms functioning during power outages, a critical requirement in many regions. Five alarm conditions (high/low temperature, power failure, voltage abnormal, door ajar, and backup battery) provide comprehensive protection. A standard laser printer generates temperature records for cold chain documentation and audit trails.

Vaccine Transport & Last Mile Delivery

Maintaining the cold chain during vaccine transport is one of the greatest challenges in immunization programmes. WinHyCare mobile coolers are actively refrigerated transport units — not passive coolers that rely on ice packs. They provide continuous, reliable cooling during transit from distribution centres to vaccination sites. Operating on multiple power sources (AC 220V, AC 110V, DC 12V vehicle power), our mobile coolers support three temperature modes: 2-8°C for standard vaccines, -10°C to -25°C for frozen vaccines, and 22±2°C for platelet products. The whole-roll PE anti-collision structure ensures protection during road transport, while forced-air internal cooling maintains temperature uniformity throughout the storage chamber.

Cold Chain Monitoring & Compliance

Every WinHyCare storage and transport unit is equipped with comprehensive monitoring capabilities to support cold chain compliance documentation. USB data ports enable temperature log downloads for regulatory auditing. Digital displays with 0.1°C resolution provide real-time visibility, while remote alarm contacts allow integration with facility-wide monitoring systems. For organizations managing vaccine programmes across WHO, UNICEF, or national guidelines, our equipment meets the documentation and traceability requirements specified in Good Distribution Practice (GDP) and Vaccine Storage and Handling guidelines.
