ConclusionsConclusionsConclusionsConclusions
Close cooperation between compressor and system
manufacturer is essential during system design.
Mixing scroll and semi-hermetic compressor technology in a
booster system does not require any special design change.
Using Scroll Compressors with proven Digital Technology
instead of costly Semi-Hermetic compressors with inverterinstead of costly Semi-Hermetic compressors with inverter
keeps the investment cost competitive. They are a superior
solution also in Hybrid Systems, in which its advantages are
multiplied.
CO2 has been the refrigerant choice also for small format shops
where Scroll Technology represents a reliable, cost-effective,
energy efficient and compact solution.
Therefore, combining Scroll and Semi-Hermetic Compressor
Technology in a system, convenience store operators can
afford to make the transition to CO2.

  • 20. ConclusionsConclusionsConclusionsConclusions Close cooperation between compressor and system manufacturer is essential during system design. Mixing scroll and semi-hermetic compressor technology in a booster system does not require any special design change. Using Scroll Compressors with proven Digital Technology instead of costly Semi-Hermetic compressors with inverterinstead of costly Semi-Hermetic compressors with inverter keeps the investment cost competitive. They are a superior solution also in Hybrid Systems, in which its advantages are multiplied. CO2 has been the refrigerant choice also for small format shops where Scroll Technology represents a reliable, cost-effective, energy efficient and compact solution. Therefore, combining Scroll and Semi-Hermetic Compressor Technology in a system, convenience store operators can afford to make the transition to CO2.
