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
