See air purging in a new light – energy efficient Air Purger for NH3 systems
The Danfoss Intelligent Purging System (IPS) is an automatic, self-contained operating unit that helps remove non-condensable gases in a safe and energy efficient way. This helps maintain an optimum refrigeration capacity and system efficiency, allowing professionals to achieve maximum system performance.
Maximize system performance
- Automatic purging response to non-condensable gases in the refrigeration system
- Continuous monitoring of differential pressure between system refrigerant and purger refrigerant
- Reduction of plant power consumption
- 8 point purging functionality
- Built-in Modbus communication enable easy sharing of essential data
- Purger refrigerant charge less than 150 g of Propane (R290)
- Natural environmentally friendly green refrigerant with low GWP and high purging efficiency - 7.5% NH3 release
- Scans and purges when necessary
Easy installation and maintenance
- Cost-effective design with few mechanical and electrical connection interfaces
- Minimizes the risk of leakage thanks to the hermetic internal cooling system
- Plug and play, stand-alone unit eases installation and commissioning – low risk of potential error
- No need for any advanced settings
- Easy to handle with its compact design
- Fast and easy pump down before service
Improve operational safety
- Electronic smart purging helps reduce the risk of refrigerant release to the environment
- No need for oil management from the ammonia system
- Self-contained operating unit functions independently from the main plant
- Easy monitoring of past purging cycles data with operation log
- Self-diagnostics for unit and system operation to shut down in case of malfunction of air-purger components
- Advance Bubbler support functions included
- LLS 4000 support increase system protection level

Webinar

This on demand webinar is about how the proven IPS 8 design integrates with propane (R290) for reliable, demand-based purging in a compact, standalone unit. Understand how the IPS 8 adapts to system conditions, optimizes purging with R290, and benefits from a standalone, oil-free design.
Case stories
As Korea’s leading beer company, OB Beer accounts for more
than 80% of Korea's beer exports with more than 24 types of
beer exported to more than 24 countries around the world.
Founded in 1933, OB Beer produces high-quality beer at three
major breweries. Recently, the company replaced its manual air
purger in their breweries with the intelligent Danfoss IPS 8,
which now provides lower energy costs while maintaining
maximum system performance.
