Scroll compressors
Danfoss scroll compressors H and S series have been used for more than 10 years in R410A HVAC units. With a very wide application envelope they suit varied applications such as rooftops, chillers or process cooling, reducing the number of items held in reference and inventory. The Danfoss Scrolls with IDVs come with an even wider operating envelope for higher flexibility in system designs for a wide range of applications.

Available for R452B, R454B and R32 lower-GWP alternatives.
Innovative features for higher system reliability
A new level of compressor robustness and system reliability:
Intermediate discharge valves: Reduce the load on mechanical parts at start up, provide safer operation at high condensing and evaporating temperatures and contribute to better liquid management
Surface coating on thrust bearing and polymer bearings: Improves compressor robustness in low lubrication conditions (start-up)
Organ pipe: Maintains safe oil level at part-load in manifold configurations
Integrated discharge temperature protection*: Prevents operation outside the operating envelope
Integrated non-return valve*: Reduces refrigerant migration from high-pressure to low-pressure side after compressor shutdown
Modified gas flow path (snorkel) and sealed lower bearing: Improves flooded start capabilities and overall compressor robustness against liquid slugs. Additional Reverse Vent Valve on DSH 090 to DSH 184 prevent damage from reverse rotation in case of wrong phase connections. On the large platform (DSH 240 to 485), it is monitored by the electronic board.
Unparalleled manifold compressor performance
Today, almost 90% of all commercial scroll air conditioning systems use manifold compressors.
Compressors in manifold configurations offer:
Flexibility in staging
High part-load efficiency
Improved uptime
Low applied costs
Lower sound levels
Mastering the manifold designs over the years, Danfoss addresses the complex challenges that our customers face in extending their system capacities when using multiple scroll compressors.
Our safe compressor operations with static and dynamic manifold piping design offers best in class performance under both full-load and part-load conditions. Each of the Danfoss large compressors is equipped with an oil equalization connector and oil sight glass rendering it ready for use in single, tandem or trio configuration with no additional cost.
The Danfoss manifold configurations offer a wider capacity modulation. Our even and uneven manifold configurations up to 120TR in one circuit offer wide staged capacity modulation. For example, a system with six manifold compressors in two circuits offers capacity modulation from 17% to 100%. This enables higher part-load efficiency compared to screw technology in a system of equivalent capacity. Danfoss IDV technology, implemented in the 7.5-40 ton range of the fixed-speed Danfoss Scrolls DSH and Danfoss inverter Scrolls, further enhances energy efficiency under part-load conditions.
Mechanically, the sound level is also significantly lower than alternative compression technologies in larger capacities.

CH
The Danfoss CH series scroll compressors, including the CH290 and CH485 variants, are engineered for a wide range of HVAC applications such as rooftops, chillers, and process cooling. Renowned for their reliability, efficiency, and versatility, these compressors utilize R410A refrigerant and are designed to minimize environmental impact with a focus on reducing carbon footprint and ozone depletion potential. With a reference service life of 10 years, the CH series ensures long-term performance and sustainability. Ideal for commercial and industrial use, these compressors offer compact size and high efficiency, making them a preferred choice for modern HVAC systems.
DCJ
Danfoss DCJ series scroll compressors are manufactured using the most advanced machining, assembly, and process control techniques. In the design of both the compressor and the factory, very high standards of reliability and process control were the first priority. The result is a highly efficient product with the highest reliability obtainable, and a low sound level.
DSG
Danfoss DSG compressors excel in process chillers, comfort cooling, and heat pumps, offering efficiency with R1234ze and R515B refrigerants. The DSG range targets process chillers, comfort cooling, and heat pumps in the 40 to 240T range (650kW@50Hz), specifically optimized for these refrigerants. These compressors achieve higher efficiency without expanding their footprint. The DSG range stands as a reliable solution, offering efficient performance across diverse industrial cooling and heating applications.
