BOCK® hydrocarbon compressors: The natural choice

Hydrocarbons are gaining ground as a natural refrigerant alternative in applications like supermarket refrigeration and chillers. Danfoss BOCK®'s hydrocarbon compressors are based on the HG well-known platform, and offer long-term reliability and safety for system manufacturers, users, and investors.

Our specialized HC compressors come with safety modifications and are optimized for hydrocarbon use. However, please note that only trained experts should operate them, adhering to safety measures and an agreement on hydrocarbons as a refrigerant (BOCK Art. No. 09996).

Features and benefits of hydrocarbon compressors:

Optimized total cost of ownership (TCO): cost-effective HC compressor version available, including non-ATEX option

Highest efficiency: achieve maximum efficiency for your operations

Sustainable solution: embrace an eco-friendly approach with hydrocarbon compressors

Holistic design: specifically tailored for hydrocarbon applications

Reliable long-life design: benefit from over a decade of experience in various applications

Wide & safe operating range: the market's largest reciprocating HC range offers versatility and safety, even in special applications

Differences to a standard HG compressor

The HC compressor program encompasses 7 model sizes with 25 capacity stages from 5.4 to 281.3 m³/h (50 Hz). They are optimized for all hydrocarbon requirements and varies from the standard HG-series:

  • Oil sump heater (necessary)
  • Thermal protection thermostat (recommended)
  • Special oil charge
  • Durable driving gear for demanding applications with hydrocarbons
  • Electronic motor protection
  • INT69 G enclosed for installation in the switch cabinet

ATEX compressors

Safe compressors for explosive atmospheres: BOCK®s ATEX/IECEx compliance

First European manufacturer to offer ATEX/IECEx compliant compressors. These components are essential for equipment operating in explosive atmospheres, adhering to stringent safety standards.
Our reliable semi-hermetic gas-cooled HG compressors serve as the foundation for applications in potentially explosive environments, backed by our quality management system compliant with EN 80079-34, meeting ATEX and IECEx requirements.
