Reduce supermarket heating bill and CO2 footprint with Danfoss heat recovery unit
The Danfoss Heat Recovery Unit helps to eliminate the technical challenges of managing heat recovery. The HRU is an integrated solution managing and buffering the heat from the CO2 refrigeration pack – to be reused for space heating, hot tap water, or even sold to neighbors or district heating grids.
Remote controlling and monitoring
The HRU is packed with Danfoss’ automatic controller ECL which offers possibilities for external communication. Further Danfoss offers a web-based solution called Leanheat Monitor , which enables remote controlling, monitoring and alarming functionalities from the substation. Visualization via Leanheat Monitor provides easy access to monitoring and control of your HRU via PC or Smartphone and enables you to unlock your resources to focus on your primary business.
Construction and Installation
The HRU is designed as floor station and it is delivered in one piece, with possibility to be split into 3 parts, which allows the HRU to be transported through narrow corridors. All heat exchangers are produced with Micro Plate technology develop by Danfoss, which significantly increase substation performance and lifetime. Standard unit layout allows to prepare connection piping inside the building before station is delivered. Piping prepared with automatic welding machines ensure highest possible welding quality.

Getting supermarkets to net zero
With the world’s population expected to reach 10 billion people by 2050, sustainable food retail and storage are more important than ever. Yet this is an often-overlooked step in the decarbonization of society.
Supermarkets turned into heat suppliers
Supermarket chain focus on the green energy transition with Danfoss heat recovery units.
Introducing the Heat Recovery Unit for sustainable savings
In this video our product manager Dawid Lawreszuk explains how the Heat Recovery Unit operates and what benefits it provides for the supermarket in terms of energy efficiency and carbon footprint.
Case stories
Climate friendly solution
The HRU is environmentally friendly and it reduce CO2 emissions. Especially supermarkets can accumulate excess heat from cooling systems to heat up shop area. In some areas waste heat via heating networks can be transferred to household. System efficiency ensure short “return of investment” time and allows to save money for heating in longer term.
Prefabrication ensures jobsite efficiency
The HRU is produced based on a 3D model prepared by our design department. All components for example: heat exchangers, control valves, pumps and measuring equipment are virtually connected with piping. Based on 3D-drawings pipes are bent, cut and welded with support of automated machines ensuring supreme quality and short delivery time. Units are designed as modular constructions, which makes transportation and assembly easier. Heating units includes an electrical wired panel, which is functionally tested and ready to use after connecting power supply to the cooling substation on site.
Danfoss substation is a complete product: designed, produced and tested – ready for use. Danfoss has more than 40 years of experience in production of substations, which guarantees great functionality.
Features and benefits
The HRU significantly reduce heating cost (ROI in 1-3 years depending on current heating source)
The prefabricated substations reduce space demand with up to 30% compared to build-on-site solutions
Easy installation and use with remote access via Danfoss free cloud based ECL portal or via other protocols like Modbus
All Danfoss products are manufactured according PED 2014/68/ EU and is compliant to ISO9001/ISO14001/ IATF 16949 automotive
