What is savENRG® Arctic Vault?

The savENRG® Arctic Vault is a Phase Change material-based thermal backup system designed for Walk-in Freezers with a proprietary IoT-enabled geolocation and time-stamped temperature & humidity monitoring system to provide the following key risk mitigation benefits:
Extends temperature hold time during outages
Reduces compressor workload
Protects sensitive products

Why install savEnrg® Arctic Vault?

As a cold storage facility manager, ensuring consistent temperature control is critical for protecting inventory, reducing operational costs, and maintaining compliance with industry regulations. Integrating Arctic Vault into your walk-in freezers is a cost-effective, reliable, and energy-efficient solution to enhance temperature stability, reduce operational risks, and ensure compliance in your cold storage facility.

Maintain Temperature Stability: PCM acts as a thermal buffer, absorbing excess heat when the freezer experiences power failures or temperature fluctuations. This ensures stable temperatures and prevents spoilage, reducing the risk of costly product losses.

Extend Temperature Hold Time During Outages: In the event of a power failure or mechanical issue, PCM provides passive cooling, keeping the freezer at safe temperatures for an extended period. This allows more time to restore power without immediate reliance on costly backup generators or emergency interventions.

Lower Energy Consumption and Reduce Costs: By absorbing and releasing thermal energy, PCM helps optimize compressor usage, reducing run times and energy consumption. This leads to lower electricity bills and less wear on cooling equipment, extending its operational lifespan.

Reduce Load on Backup Generators: Instead of overloading diesel generators or battery backups during power failures, PCM reduces the cooling demand, improving energy efficiency and ensuring that generators last longer with lower fuel consumption.

Protect Temperature-Sensitive Inventory: For cold storage facilities handling vaccines, pharmaceuticals, frozen foods, or other perishable goods, PCM ensures that critical temperature thresholds are maintained. This helps comply with FDA, USDA, or GDP (Good Distribution Practice) regulations while reducing the risk of spoilage claims.

Support Sustainability Initiatives: By reducing energy consumption and optimizing cooling efficiency, PCM technology contributes to sustainability goals, lowers your carbon footprint, and enhances the facility’s overall energy efficiency.

How does savEnrg® Arctic Vault work?

Arctic Vault uses phase change materials (PCMs) to absorb, store, and release thermal energy, helping maintain stable temperatures during power failures or fluctuations. Here’s how it works:

PCM Charging (Freezing Phase)
PCM panels or packs are installed inside the walk-in freezer, typically on walls, ceilings, or shelving units.
When the freezer operates normally, the PCM absorbs cold energy and freezes at a specific phase change temperature (e.g., -10°C for a freezer).
The PCM remains solid as long as the freezer maintains its normal operating temperature.

Passive Cooling (Melting Phase)
If there is a power outage, equipment failure, or a door is left open, the temperature inside the freezer begins to rise.
As the temperature of PCM reaches its melting point, it absorbs heat from the surroundings, preventing the freezer’s internal temperature from rising too quickly.
This process extends the time before the temperature exceeds critical thresholds, protecting stored goods from spoilage.

Recharging Once Power is Restored (reFreezing Phase)
When power returns and the freezer resumes operation, the PCM refreezes, recharging itself for future thermal buffering.
The system continues to cycle through these charge and discharge phases, providing continuous thermal backup.

What is the benefit of actively monitoring the temperature & humidity for a savEnrg® Arctic Vault?

Actively monitoring temperature and humidity in a freezer with a PCM-based thermal backup system provides several critical benefits:

Early Detection of Temperature Deviations: Even with a PCM backup, prolonged power outages or mechanical failures can still lead to temperature excursions. Real-time monitoring ensures that you receive alerts if temperatures approach unsafe levels, allowing for quick corrective action.

Optimized PCM Performance: PCM effectiveness depends on maintaining proper charging (freezing) conditions. Monitoring ensures the freezer consistently reaches and maintains the PCM’s freezing point for maximum thermal backup efficiency.

Compliance with Safety and Regulatory Standards: Industries like pharmaceuticals, healthcare, and food storage require strict temperature control for product integrity. Continuous monitoring provides documented proof of compliance with regulatory bodies such as the FDA, CDC, or HACCP guidelines.

Protection Against Humidity-Related Issues: High humidity levels can lead to ice buildup, which may reduce freezer efficiency and impact PCM performance. Monitoring humidity helps prevent excessive frost formation, reducing maintenance needs and improving energy efficiency.

Extended Equipment Lifespan & Reduced Energy Costs: Monitoring helps identify inefficiencies, such as compressor overwork or door leaks, which can lead to higher energy consumption and wear on cooling equipment. By detecting these issues early, you can take preventive actions, reducing repair costs and extending the life of the freezer.

Improved Product Quality and Reduced Losses: A PCM system helps mitigate temperature fluctuations, but precise monitoring ensures you know how long the freezer stays within the safe range during outages. Preventing temperature excursions reduces the risk of spoiled inventory, protecting valuable products.
