EMS - Equipment Monitoring System

Future-proof your vaccine storage with the latest WHO PQS standards.

The updated EMS is designed to meet the latest WHO PQS (Performance, Quality and Safety) requirements for data logging and monitoring in Cold Chain Equipment. This ensures that our solutions remain at the forefront of global standards for vaccine storage and healthcare logistics. The integrated EMS system is available in levels 1-3 across the full VLS range.

Why WHO introduced new EMS requirements.

The new PQS specifications for EMS levels 1, 2, and 3 were developed to address key challenges and opportunities in cold chain management:

• Standardization: Previous systems lacked consistent data formats and interoperability, making integration with LMIS/eLMIS difficult.

• Local Access: Health workers and technicians often had limited access to performance data for troubleshooting and maintenance.

• Data Ownership: Unclear protocols for owning and sharing data between systems, leading to inefficiencies and data silos.

• Comprehensive Diagnostics: Beyond temperature, new requirements include logging door openings, power availability, compressor runtime, error codes, and temperature history.

• Future-Proofing: Machine-to-Machine (M2M) interfaces allow easy upgrades and evolving technology without replacing entire units.

• Global Health Alignment: Supports Gavi and WHO initiatives for data-driven decision-making in vaccine logistics and cold chain management.

 What this means for you.

With Vestfrost EMS, you get:

• Full compliance with WHO PQS standards

• Enhanced data integration for LMIS/eLMIS systems

EMS levels 1 - 3

 All EMS levels are built on the same base model, making upgrades simple:

 Replace display to move from Level 1 to Level 2.
Add SIM card for Level 3 remote connectivity

 Level 1

Basic local monitoring

Data logger with USB data access.

• Logs .pdf reports and raw data.
• EMS-reported data includes error codes, power availability, compressor runtime, equipment ID, door openings.
• Level 2 & 3 modules can be added by plugging into the USB connector.

Level 2

Advanced local monitoring

Level 1 + local display and alarm.

• Level 1 functions, and...
• Local users monitor display without needing to download data.
• Visual/audible alarms prompt action from local users when urgently needed.

Level 3

Remote and local monitoring

Level 2 + remote transmission.

• Level 2 functions, and...
• SMS/email alarms prompt remote users.
• Users can access data remotely.
• Data automatically routes to dashboards or future eLMIS systems.
