FREOR offers 5 ways to improve energy efficiency in commercial refrigeration


Amid a potential global energy crisis that may significantly impact the economy, the environment, and people’s well-being worldwide, FREOR wants to encourage its clients and partners to contribute to energy conservation.

As a manufacturer of commercial refrigeration equipment, FREOR knows how essential such equipment is for supermarkets. Yet, according to a study on energy management by the EHI Retail Institute, refrigeration equipment also accounts for a huge 48% share of supermarkets’ energy consumption.

However, refrigeration systems can be an easy and effective place to start saving energy in grocery retail – since even minor improvements can drastically boost overall energy efficiency.

FREOR aims to help retailers not just reduce their energy bills but also avoid possible energy shortages. Here FREOR offers several tips that can significantly impact a store’s energy consumption and help avoid an energy crisis.

FREOR suggestions to consider for improving energy efficiency

  1. Switch to environmentally friendly propane gas (R290) refrigerant. Our Green Wave R290 refrigeration equipment, which operates with natural, non-toxic R290 refrigerant, can help supermarkets save up to 30% on energy compared to HFC systems.
  2. Invest in energy-effective cooling solutions like FREOR’s Hydroloop system. Refrigeration equipment operating on a Hydroloop system use up to 30% less energy than traditional cooling systems. And with a Hydroloop Glycol or Hydroloop Hybrid system, excess heat can be reused to warm store premises and water – a huge gain towards becoming even more energy efficient.
  3. Use Dual Air Curtains and night curtains on the refrigeration equipment. FREOR’s most popular multideck JUPITER comes with Dual Air Curtains installed by default, minimizing temperature differences inside the equipment for energy savings of up to 20%. Additionally placing night curtains over open refrigerated display cases during a store’s non-working hours can yield even bigger energy savings.
  4. Pick commercial refrigeration equipment with glass doors or lids. Doors reduce the amount of energy needed to maintain the right temperature inside. Refrigerators with glass lids or doors can save up to 75% of the energy used by open cabinets.
  5. Go with LED lighting and energy-saving fans, which are standard on FREOR refrigeration equipment. FREOR uses energy-saving electronically commutated fans, which are up to 30% more efficient than traditional AC fans. LED lighting, meanwhile, not only improves product visibility but, more importantly, consumes less energy and induces less heat, resulting in less electricity used to keep products at the right temperature. Of course, the most basic way to raise energy efficiency is to always turn lighting off during non-business hours.

Today it is more than necessary than ever for supermarkets to rethink their commercial refrigeration energy usage and start taking action to save energy. Even simple steps, like turning off lighting when a stores is closed and using night curtains on open refrigeration displays, can significantly improve energy efficiency. Now is the time to invest in energy-efficient cooling solutions, and FREOR is always ready to help to achieve energy conservation goals.
