BOCK® semi-hermetic compressors: Your sustainable choice for all HVAC-R needs

Danfoss BOCK® compressors are your go-to choice for commercial and industrial refrigeration systems worldwide, spanning air conditioning, cooling, heating, heat recovery, and heat pumps. Our commitment to a greener future has led us to innovate efficient and reliable CO2 and other low-GWP refrigerant compressors, ensuring functionality, economic efficiency, and environmental responsibility go hand in hand.

But that's not all; we're also pioneers in semi-hermetic hydrocarbon compressors for refrigerants like R290 (propane) and R1270 (propene), meeting all F-Gas Regulation requirements for long-term use. Welcome to the sustainable world of Danfoss BOCK® compressors.

Features and benefits of semi-hermetic reciprocating compressors:

Natural refrigerant—R744 and R290—and low-GWP refrigerant ranges to fit all application requirements.

CO2 transcritical and subcritical applications

ATEX HC models available

Versatility: suitable for a wide range of stationary and mobile applications

Efficiency: flexible performance tailored to specific needs, leading to cost savings

Reliability: exceptional durability, even in challenging conditions

Eco-friendly: compliant with environmental regulations and standards

Oil pump reliability: reliable oil supply, even in smaller capacities

Natural Refrigerants in Focus

Embracing the Future: Natural Refrigerants in Focus

The changing global climate is a reality we face every day, with our planet growing increasingly. As an industry, we have a responsibility to take action. With 15% of the world's electricity consumption used for refrigeration and air conditioning, the way we manage, control and optimize cooling will become even more important.

In the compressor development we have been committed to natural refrigerants since 1993, offering a range of compressors for CO2 (R744) and hydrocarbons (HC). Additionally, we invest in developing compressors that use low-GWP refrigerants to continue driving innovation in the synthetic refrigerant sector.
