IPro Genius is the cherry on top of Emerson’s CO2 booster system

At this year’s AHR Expo in Chicago, Emerson had their IPro Genius programmable controller on display. The IPro Genius controls high-pressure controls and bypass valves effectively to help maintain a constant flash tank pressure which is one of the keys to full efficiency when using a transcritical CO2 booster system and adds to the larger system to ensure optimal results for commercial refrigeration.

Systemes LMP installs CRYSTAL CO2 unit at Canadian ice arena

R744 technology innovator Systemes LMP has created a CO2 system for artificial cooling of ice slabs called the “CRYSTAL”, already installed at an ice arena in Canada. The CRYSTAL is a multi-compressor unit with an operating capacity of 30 to 140t ideal for new constructions of ice rinks under renovation. Thanks to its state-of-the-art design, the unit features total heat recovery of the compressors, which can be used for commercial space heating, hot water, mechanical room.
