Key Takeaways
Reliable temperature monitoring solutions for COVID-19 vaccines safeguard efficacy by ensuring strict cold chain compliance from ultra-low storage to final administration.
The Pfizer vaccine requires meticulous thermal management across multiple distinct stages including long-term deep freeze and short-term refrigeration.
Automated alerts from advanced wireless
monitoring systems Seamless local network data access enables healthcare leaders to analyse long-term environmental trends and proactively prevent vaccine spoilage.
As the word begins to turn again with the introduction of a COVID-19 vaccination, this has not been without significant planning and preparation. Behind the scenes, the rollout of these vaccines has involved a vast amount of infrastructure and instrumentation to support hospitals and vaccine hubs. In 2012, ECEfast began using Hanwell systems and technology for temperature monitoring solutions. Almost 10 years later, we are now their largest distributor in the world. With this experience, we provided advanced temperature monitoring solutions for COVID-19 vaccines throughout NSW, using Hanwell technology, ensuring vaccinations are stored at the necessary temperatures.
Why are temperature monitoring solutions for COVID-19 vaccines important?
For vaccines to work as they should, storage at the correct temperature is vital. The Pfizer vaccine for example, has several temperatures it can be stored at depending on when it will be delivered. It starts with a shelf-life of 6 months at temperatures below -70C. Once thawed for use when needed, the shelf life drops to 5 days when stored between 2 and 8 C. Above 8 C, it has a life of 2 hours undiluted and 6 hours diluted, ready for injection.
At each of these stages, temperature monitoring data must be readily available to ensure vaccines are being stored at the perfect temperature. By using Hanwell technology, this data is always easily accessible.
How does wireless temperature monitoring solutions for COVID-19 vaccines work?
The Hanwell system used, is designed to monitor the temperature of refrigerators and freezers within hospitals /vaccine hubs and alert staff directly, assisting in keeping drugs and vaccines safe from damage and the public safe from harm.
A high accuracy sensor is placed in each fridge or freezer and connected through Hanwell EMS (environmental monitoring software). When the temperature within one of those fridges breaches pre-determined settings, a buzzer will sound to alert the staff. Normally someone would need to go to a PC to view the alarm but with Hanwell, this is a thing of the past. The alarm notification and actions will be delivered to a nominated printer for staff to quickly identify and rectify.
Because this system also stores the data on a local network, it can be used by senior staff to access, analyse, and identify any potential trends that may cause problems in the future.
Where are Hanwell temperature monitoring solutions used for COVID-19 vaccines?
Hanwell wireless monitoring systems are installed in all Sydney metro Local Health Districts.
They provide important temperature monitoring and alerts for drugs and vaccines in 90% of Sydney hospitals. Almost 1000 fridges and freezers are now monitored automatically on the NSW Health network.
Hanwell is a known and trusted platform throughout NSW Health. With this dependability and infrastructure in place, these systems have also been extended to include Covid-19 Vaccine Hubs for RPA, Westmead and Liverpool Hospitals.

Frequently Asked Questions
Why are specialised temperature monitoring solutions for COVID-19 vaccines required?
Vaccines like the Pfizer formula have strict, multi-tiered thermal requirements to remain effective. They demand precise tracking across various stages, moving from ultra-cold storage below -70°C down to standard refrigeration levels between 2°C and 8°C before patient delivery.
How do wireless environmental monitoring systems protect vaccine integrity?
High-accuracy wireless sensors continuously track refrigerator and freezer conditions, sending automated alerts to staff the moment a pre-determined threshold is breached. You can explore our dedicated hardware like
What happens if a COVID-19 vaccine is stored above its recommended temperature?
Storage above optimal limits severely reduces vaccine shelf life. For instance, an undiluted vaccine may only remain viable for two hours at room temperature, making continuous, automated monitoring absolutely essential to avoid costly medical waste.
Where are these automated vaccine monitoring setups currently implemented?
These reliable systems are widely deployed across major metropolitan vaccine hubs and local health districts, automatically safeguarding almost 1000 fridges and freezers on the public health network. For tailored support with your clinic or laboratory infrastructure, please
