1. WHAT IS THERMAL ENERGY STORAGE (TES)?
TES is the storing of excess thermal energy (energy in a system due to its temperature) for future use.
2. HOW DOES YOUR THERMAL ENERGY STORAGE SYSTEM WORK?
The Viking Cold TES system leverages existing refrigeration equipment in low-temperature facilities to freeze Phase Change Material (PCM) when energy costs are lower and system efficiencies can be exploited. This allows intelligent controls to turn off refrigeration equipment during periods of high energy costs while the PCM maintains temperature stability and low energy consumption. The result is 20% to 35% lower energy costs, 38% greater temperature stability and more efficient, longer lasting refrigeration systems.
3. WHAT IS INCLUDED IN THE VIKING COLD SOLUTIONS TES SYSTEM?
Our Thermal Energy Storage system includes three components:
  • Phase Change Material (PCM)
  • Control System
  • Remote Monitoring & Reporting Portal
4. WHAT IS A PHASE CHANGE MATERIAL (PCM)?
Phase Change Materials (PCM) store and release energy when they transition between their solid and liquid states. While changing phases our engineered PCM absorbs 300 times more heat than food.
5. IS YOUR PHASE CHANGE MATERIAL SAFE TO USE?
All our PCM formulations are comprised of deionized water and inorganic salts. They are food safe, environmentally friendly, non-toxic and non-combustible. The entire system is also 100% recyclable.
6. ARE THERE ANY MECHANICAL PARTS IN YOUR TES SYSTEM?
No. There are no mechanical parts (pumps, motors, actuators, compressors, etc.) in our TES system. They leverage existing refrigeration equipment. The PCM is housed in self-contained cells mounted in stationary positions throughout the facility.
7. WITH WHICH REFRIGERATION SYSTEMS DOES YOUR TES SYSTEM WORK?
Our solution is refrigeration system agnostic and works with any properly maintained system.
8. WITH WHICH CONTROL SYSTEMS DOES YOUR TES SYSTEM WORK?
Our TES system is extremely flexible and can be integrated with any existing control system. We also have our own control system that can drive the refrigeration system in conjunction with our PCM.
9. DOES THE VIKING COLD TES SYSTEM AFFECT OTHER FREEZER COMPONENTS?
No. Our system actually integrates with existing racking systems, does not reduce any storage space, does not limit sprinkler or fire suppression systems, will not affect your commodity classification and will not impede or disrupt any logistical operations in your facility. In fact, the system’s controls and remote monitoring actually improve overall efficiencies and allow for predictive maintenance of other system components.
10. CAN YOUR SYSTEM BE INSTALLED INTO EXISTING FACILITIES (RETROFIT)?
Yes. Viking Cold systems can be installed as a retrofit, refurbishment or in new construction projects. The sooner they are installed, the sooner that facility will start to see reduced energy expenses, improved temperature stability and increased refrigeration system efficiencies.
11. WHAT ARE TYPICAL ENERGY SAVINGS?
Our clients save between 20% and 35% of their energy expenses while maintaining greater temperature stability.
12. DOES THE TES SYSTEM MAINTAIN TEMPERATURE STABILITY?
Yes. Our TES system is engineered to maintain temperature stability within the specific temperature range for each facility; providing fewer fluctuations and a 38% slower rise in temperatures.
13. CAN YOUR SYSTEM PROVIDE THERMAL BACKUP PROTECTION?
Yes. In the event of power outages or equipment failure, we have seen temperatures remain stable three times longer with our TES system installed.
14. DOES THE TES SYSTEM IMPROVE REFRIGERATION EFFICIENCY?
Yes. The Viking Cold system maintains stable temperatures while allowing the existing refrigeration system to be turned off for extended periods of time. When the systems are running, they run at full capacity at times when ambient temperatures are lower, enabling greater refrigeration efficiency and less energy usage. The reduced mechanical run time of the refrigeration equipment also leads to less maintenance and longer equipment life.
15. DOES YOUR SYSTEM INTEGRATE WITH ON-SITE SOLAR POWER GENERATION?
Yes. Our system pairs very well with onsite solar/PV generation to dramatically increase solar ROI. Our solar clients have seen a reduction of 39% annualized energy expenditures and 95% overnight grid reduction, directly addressing grid challenges related to the “duck curve”.
16. HOW LONG WILL YOUR SYSTEM LAST?
The life of the Viking Cold TES system is 20+ years.
17. HAS YOUR TES SYSTEM BEEN APPROVED OR VERIFIED BY ANY OUTSIDE PARTIES?
Yes. Our system installations have been accepted and funded by numerous utilities as part of energy saving incentive programs, as well as being proven effective in a third-party validation study (click here) performed by the California Energy Commission’s Emerging Technology Coordinating Council.

Food Engineering Logo Food Engineering names Viking Cold among most innovative cold storage technologies

Viking Cold has been included by Food Engineering in an article looking at leading innovators in the field of food refrigeration. The Thermal Energy Storage (TES) system at the core of Viking Cold’s offering was incorporated within the industry title’s selection of new and exciting methods for temperature-controlled management of refrigerated and frozen foods. Alongside mentions for Messer and Tippmann Innovation, the piece highlighted the growth in demand for TES as increasing numbers of processors and cold storage providers understand the energy-efficiency and cost-saving benefits that TES can bring. Collin Coker, Vice President of Sales and Marketing, underlined the untapped potential for high energy users to “wring out more value with thermal energy storage”, using the system’s intelligence controls to reduce consumption at peak periods or when pricing levels are at a premium. The benefits of TES listed by Food Engineering included that fact that it is environmentally friendly while providing a highly efficient, stable and resilient environment for protecting food products. Coker went on to explain the versatility and low maintenance demands of the system, with the ability to install cells on top of racking in a diverse range of food environments, from smaller processors and walk-in freezers up to larger distribution centers. At a Dreyer’s Ice Cream facility for Nestlé with a two-pallet position racking system and a lower roof, for example, cells could be incorporated into the design of the ceiling. “They (the cells) sit up there. They do their thing. They act as a very sophisticated heat sink. There’s no mechanical interface or requirements,” Coker said. Food Engineering is a monthly magazine and associated website that cover manufacturing technologies in the areas of processing, packaging, food safety, plant operations, material handling and automation.
