Senna

refrigeration booster unit
Senna

Senna is our newest range of transcritical CO₂ refrigeration units, designed to combine simplicity, compactness, and high reliability. The Senna range includes eight sizes, each with a wide choice of compressor models: MINI, SMALL, TOP MAXI, PLUS, LARGE-200, LARGE-300 and LARGE-400. Sizes MINI to PLUS are only 850 mm wide, making them ideal for installation in plant rooms with restricted footprint and/or where access is through narrow doors.

The Senna range is ideal for medium-sized commercial refrigeration systems in food retail, food storage, process cooling and other similar applications. It is available in single temperature or dual temperature (MT and LT) configurations. Senna units can be customized with cladding for sound insulation or outdoor installation. They can also be supplied as a plug-and-play mono-block version, mounted on a skid with an integral gas cooler, complete with refrigerant piping and electrical connections.
