FAQs

Yes. Supermarkets are one of the sectors identified by Celsius Systems as using its technology. ENRG SAVR can be applied to refrigeration rack (pack) systems, suitable commercial refrigeration equipment such as display cabinets, multidecks, fridges and freezers.

Yes. Restaurants and food-service businesses can use ENRG SAVR on suitable commercial refrigeration equipment, helping to reduce unnecessary refrigeration cycles and potentially lower energy and maintenance costs.

Reducing unnecessary on/off cycling reduces the amount of work carried out by compressors and other refrigeration components. This can help reduce wear and tear, potentially increasing equipment longevity and reducing maintenance requirements.

Yes. Using less electricity for refrigeration can help businesses reduce the carbon emissions associated with their energy consumption. Celsius Systems positions ENRG SAVR as part of a wider approach to reducing energy waste and helping businesses work towards their sustainability and carbon reduction goals.

Yes. Because ENRG SAVR is designed to reduce unnecessary refrigeration cycles, it can reduce strain and wear on compressors and other components. This will contribute to lower maintenance costs and less equipment downtime over the life of the system.

Yes. By reducing unnecessary cooling cycles and energy consumption, ENRG SAVR is designed to help businesses lower their annual refrigeration running costs. The potential financial saving will depend on the individual refrigeration system and how it is used.

No. ENRG SAVR is designed to work with existing commercial refrigeration equipment rather than requiring businesses to replace their refrigeration units. This provides a way to improve the efficiency of existing equipment without the cost and disruption of a complete refrigeration upgrade.

No. One of its key advantages is that it can be retrofitted to existing refrigeration equipment. This means businesses can potentially improve the efficiency of equipment they already own rather than investing in an entirely new refrigeration system.

Yes. Celsius Systems states that ENRG SAVR is compatible with Automated Critical Temperature Recording Systems, allowing businesses to continue monitoring refrigeration temperatures alongside the energy-saving technology.

Every refrigeration system is different, so potential savings will depend on your equipment, usage and operating conditions. Celsius Systems can discuss your refrigeration requirements and provide a quote for ENRG SAVR.

ENRG SAVR fits over the thermostat sensor or temperature probe inside a refrigeration unit. Its specially designed food-grade construction is intended to mimic the thermal characteristics of food and stored products. This means the sensor is less affected by rapid changes in surrounding air temperature, allowing the refrigeration system to operate based more closely on the temperature of the products being stored.

ENRG SAVR comes with a 10-year warranty, giving businesses long-term reassurance that their investment is protected. With a decade of warranty cover, ENRG SAVR is designed to provide a long-term energy-saving solution for commercial refrigeration.

Celsius Systems states that ENRG SAVR can reduce the number of refrigeration cycles significantly, with reductions of up to around 85% referenced on its temperature monitoring information. The exact reduction will depend on the individual refrigeration system and operating conditions.

Celsius Systems states that ENRG SAVR can reduce refrigeration energy consumption by up to 30%, depending on the system and application. Actual savings will vary according to factors such as the type of refrigeration equipment, usage and operating conditions.

The typical return on investment (ROI) for ENRG SAVR is around 6–12 months, depending on the refrigeration equipment, how heavily it is used and the energy savings achieved. By reducing unnecessary refrigeration cycles and energy consumption, ENRG SAVR can potentially pay for itself through energy savings within its first year.

The ENRG SAVR itself was introduced to the market by Celsius Systems in 2025, but it builds on the company's more than 20 years of experience working with refrigeration temperature monitoring and energy-saving solutions.

Yes. ENRG SAVR is designed to work with existing commercial refrigeration systems and is stated by Celsius Systems to be compatible with all systems. It is fitted over the existing thermostat sensor (temperature probe) rather than requiring a complete replacement of the refrigeration equipment.

ENRG SAVR is designed to be simple and quick to install. The device fits over the refrigeration unit's existing thermostat sensor or temperature probe, meaning it does not require a major modification or replacement of the refrigeration system. No disruption to business during installation, refrigeration equipment continues to operate as normal.

Yes. ENRG SAVR is specifically designed for refrigeration applications where food and other temperature-sensitive products are stored. Its food-grade construction is designed to mimic the thermal characteristics of stored products while helping the refrigeration system respond more appropriately to temperature changes.

The key benefits include: • Reduced refrigeration energy consumption • Lower annual running costs • Fewer unnecessary refrigeration cycles • Reduced compressor and component wear • Potentially longer equipment lifespan • Reduced maintenance requirements • Less risk of equipment downtime • Reduced carbon emissions • A simple solution that can be fitted to existing refrigeration equipment • Suitable for a wide range of commercial refrigeration applications

ENRG SAVR helps reduce unnecessary refrigeration cycles. By influencing the way the thermostat responds to temperature changes, it reduces the number of `Start-Ups`, times the refrigeration system switches on and off, helping to lower energy consumption, running costs and wear and tear on refrigeration components.

ENRG SAVR is an energy-saving temperature monitoring device designed for commercial and industrial refrigeration. It works with a refrigeration unit's existing thermostat sensor to help the system respond to the temperature of the stored products rather than reacting unnecessarily to short-term fluctuations in air temperature.

ENRG SAVR can be used across a broad range of commercial refrigeration applications, including Cold storage facilities, walk-in chillers and freezers, upright fridges and freezers, bench fridges and freezers, grab-and-go multidecks, refrigerated display cabinets and beer and wine fridges.

ENRG SAVR is manufactured in the UK by Celsius Systems UK Ltd. The company supplies the technology to businesses both in the UK and around the world.

ENRG SAVR can be particularly useful for businesses with significant commercial refrigeration requirements, including supermarkets, restaurants, hotels, convenience stores, food manufacturers, food wholesalers, breweries, beverage companies and cold storage facilities.

Replacing commercial refrigeration equipment can be a significant investment. ENRG SAVR offers an alternative approach by improving the efficiency of existing refrigeration systems. By helping reduce unnecessary cycles, it can potentially lower energy consumption, running costs and equipment wear without requiring a complete refrigeration replacement. It is also a more affordable option, and can last for many years.

ENRG SAVR is designed to help the refrigeration system respond more closely to the thermal behaviour of stored products, rather than reacting unnecessarily to rapid air-temperature fluctuations. It is intended to optimise refrigeration operation while maintaining the required product temperature.
