Today's HVAC systems have high demands. HVAC systems are not only required to meet energy and performance standards but also provide building owners with exceptional benefits. Oil-free systems meet and exceed these standards and demands.
Danfoss' pioneering oil-free technology and application expertise helps HVAC professionals design systems that reduce operating costs and maintenance for high demand building such as data centers, hospitals, educational institutes and other applications where minimal downtime is a critical concern.
The Danfoss Extended Oil-free program (EXO) brings together all key components for high-performance oil-free systems, including Danfoss Turbocor® compressors, advanced controls, and our range of valves for oil-free applications: OFC, OFB, and PTS. These technologies ensure maximum energy efficiency and reliability in even the most challenging building environments.
Build the perfect oil-free system today that reduces the risk of chiller downtime, decrease sound levels, and obtain higher operating cost savings by using the Danfoss EXO program.
Wide portfolio that is optimized for oil-free HVAC systems
Reduced maintenance and applied costs with a shorter payback
Most efficient, exceptionally quiet, very lightweight and compact oil-free systems
Dedicated technical and customer service around the world
PTS improve the performance and reliability of both oil and oil-free centrifugal chillers and heat pumps. These valves offer extremely fast operation, within just 5 seconds, to prevent compressor surge and ensure stable system performance during both startup and shutdown.

Discover how the OFB tight oil-free shut-off ball valve enhances reliability and prevents refrigerant migration in Turbocor® chillers and heat pumps. If you are interested in the newly developed tight oil-free shut-off ball valve engineered for oil-free chillers and heat pumps featuring Turbocor® compressors, read more here.
The OFC valve was designed to improve oil-free systems efficiency and reliability.
Explore how Danfoss's Application Development Center in Haiyan, China tests showed the OFC check and stop valve can boost energy efficiency by 3% in water‑cooled chiller systems with Turbocor® compressors—unlocking potential savings in both system design and operating costs, in the article here.
PTS stepper motor staging valves for fast, reliable surge prevention in oil-free centrifugal chillers and heat pumps. The valves open quickly at startup and release pressure at shutdown, enabling stable operation, optimal compressor pressure ratios, high flow capacity and long-term efficiency in demanding applications.
OFC type check and stop valve are designed for delivering a discharge solution that improves performance and reliability of oil-free centrifugal compressors with magnetic bearings.
NRV and NRVH can be used in liquid, suction and hot gas lines in refrigeration and air conditioning plants with fluorinated refrigerants. NRV and NRVH can be supplied with flare and solder connections. They are also available with oversize solder connections providing flexibility in the use of check valves.
Brazed plate heat exchangers featuring our unique Micro Plate™ technology. Experience superior heat transfer with our brazed plate heat exchangers featuring our revolutionary Micro Plate™ technology.
Danfoss motorized ball valves are used as safety devices when a remote shut off of the flow circulation is needed in the refrigerant line, for example in case of flammable refrigerant leak in the system.
Energy consumption is a key driver for building owners when it comes to chillers. Depending on the building size, type, and use, as well as the surrounding climate, you need different options for your chiller designs to provide the most value to your customers and differentiate yourselves in the market.
In air flow and indoor air quality-related applications, condition monitoring functionality improves system uptime and competitiveness by preventing issues before they occur.
Energy efficient and environmentally friendly heat pump solutions are essential in all modern heating and cooling of residential and commercial spaces.
