Carel and B Cool have teamed up to build a fully modulating booster refrigeration rack for ships and boats – with positive results.
Around 60% of existing stores have already been retrofitted to natural refrigerants too for more than 700 stores’ having a total CO2 installation.
The show takes place February 6–8 in Atlanta, Georgia (U.S.), and will be held concurrently with ASHRAE’s Winter Conference.

With three successful installations, the chain cites 15–25% utility savings as a key motivator for choosing R744 over R448.
Its largest transcritical inverter unit with fully hermetic compressors will be commercially available in Europe next year.
The six-cylinder transcritical HGX56 CO₂ T is designed for industrial refrigeration and heat pump applications.
A new stainless-steel changeover valve can be used both for CO2 and ammonia.
Customers are also asking about larger compressors, with little faith in HFOs as a long-term solution.
Ideally suited for small- and medium-sized shops, the modular units can be installed packed or split, indoor or outdoor.
Hillphoenix’s energy analysis tool shows only 7% difference for the Florida store, with energy savings in cooler climates.
