ECO2 Booster integrated system (BIS)

The ECO₂ Booster integrated system (BIS) is a high-performing, efficient, compact, full CO₂ refrigeration and space heating solution. Recovering the waste heat, which would normally be lost to the atmosphere, and directing it an area of the store or office. Reclaiming the wasted heat for space heating resulting in a more efficient and economical solution.

Key Themes: Heating Solution

• Utilises waste heat, and transfers it directly to store via cassettes using CO₂
• Remote gas cooler with integrated false load evaporator
• Variable speed driven compressors and Varistep secondary compressors for improved capacity control
• Typically provides 25-30^oC cassette comfort heating throughout the day
• Maintaining store temperature around 21^oC
• No need for secondary traditional heating or cooling methods
• Removes the typical condensing units, freeing up space and reducing planning issues
• High pressure CO₂ Marstair cassettes
• Developed with RDM pack and heating solution interconnectable with various front end
• Indoor or outdoor applications
• Designed and manufactured in the UK
• GWP = 1

Key Themes: Cooling Solution

• The BIS has the capability to provide additional cooling through a separate cooling circuit, reducing the risk of thermal shock and removing the need for a separate cooling cycle
• Separate expansion valves provided at each cassette
• Parallel Compressor included to improve efficiency
• Heating cycle unaffected

Maintenance

• All major components and access points in the plant are accessible. Standard products are accessible from the front and side panels provided
• Flexibility in design will ensure Space Engineering can find the right solution
• Technical and commissioning support available

• Since 2016, Space Engineering have built and supplied twelve packs to various clients. All installed and running effectively.
• An increase in demand for innovative solutions is clear with seven packs having been built since 2020. A further five committed to be installed in 2023.
• This is evident the industry is accepting and moving towards more innovation in an attempt to reduce gas emission and the negative impact on the environment
