TES Video: Savings & Temperature Stability



is among the top two operational expenses for a cold storage facility.

High Costs

Peak demand charges can be up to 70% of your electricity bill.

24 hours a day

Temperature control is required around the clock to keep food safe.


Viking Cold’s Thermal Energy Storage System makes it possible for cold storage facilities to protect what is vital while intelligently storing and deploying refrigeration to reduce energy costs. Our Thermal Energy Storage System is a passive system that never needs maintenance and works in parallel with existing refrigeration systems. As a result, electricity peak demand is reduced by up to 90 percent, a significant cost savings.

The system can be easily installed without any upgrades to your current refrigeration equipment, adding redundancy and maximizing savings.

Peak Period Reduction English


Protection From Rising Peak Energy Charges

Viking Cold’s System stores thermal energy during low cost periods of the day and uses it during high cost periods of the day saving you up to 90% of peak demand charges.

 Protection That Lasts

The Viking Cold solution is designed to last 20 years, has no moving parts and is maintenance free. Unlike competing products, the system is easy to install and works alongside your existing refrigeration equipment.

 Thermal Backup Protection

When the power goes out or mechanical systems fail, Viking Cold systems keeps your facility cold. Your business is protected from costly product loss.

 Protection In Real-time

Our monitoring and reporting system provides predictive tools to protect your business. When refrigeration begins to degrade, alarms provide early warning before expensive problems arise.

 Protection For Your Bottom Line

Viking Cold Solutions™ will work with your company to install a system tailored to your business, with many flexible purchase options to protect your balance sheet.

Anyone that pays an electric bill knows that cooling measures such as air conditioning and refrigeration require a lot of energy and cost a lot of money. So imagine the energy requirement and expense of running the refrigeration systems found in cold storage warehouses, supermarkets, and food processing facilities where temperature must be maintained at a specific level to avoid product spoilage. It’s a costly operation, but fortunately new technologies are emerging to provide thermal energy management to companies looking to cut refrigeration costs through improved energy efficiency.

reduced electricity costs, lower utility bills 4 Thermal Energy Storage Benefits That Will Improve Your Bottom Line

Viking Cold’s Thermal Energy Storage (TES) has many benefits for commercial businesses with high refrigeration based loads. Here are four of the main benefits that TES can provide. 1. Big Savings Imagine a world where gasoline costs $3 per gallon, but you could buy the same gasoline at night for $.75 per gallon. What time of the day would you buy your gasoline? You probably would buy the $.75 per gallon gasoline at night, store that energy in your gas storage tank and then use it during the day.
