Transcritical Booster Systems
Simple integrated systems designed
for supermarket applications.
Each Onyx unit harnesses the advantages of CO2 through an integrated multi-temperature solution.
Units feature a two-stage compression cycle with a common condenser and liquid line for medium temperature (MT) and low temperature (LT) applications. This two-stage design prevents significant losses as big heat exchangers aren’t necessary to condense the LT side. Just one way in which this range ensures efficiency.
Meticulously-designed suction temperature controls and oil reticulation add to each system’s durability.
A UPS system manages important valves and keeps pressure stable during a power failure.
Each unit includes a frequency inverter fitted on the compressor, electronic expansion valves, speed-controlled condenser fans and detailed, user-friendly controls.
|Number of compressors –MT/LT||2/1||3/2||4/2||5/2|
|MT capacity (kW)||75 – 115||126 – 155||150 – 192||187 – 250|
|LT capacity (kW)||7 – 11||14 – 22||14 – 33||14 – 33|
|Frequency range (Hz)||30 – 80||30 – 80||30 – 80||30 – 80|
