In addition to the single-phase units, there are also three-phase (T) models, indicating suitability for more demanding commercial or industrial applications where higher power and different electrical supply are required:

A2WHPR32M/012T (Code 20191958): Hydro Unit M 012T, with a power size of 12kW T. This "T" likely denotes a three-phase electrical supply, offering more stable and powerful operation for larger systems.
A2WHPR32M/014T (Code 20191959): Hydro Unit M 014T, with a power size of 14kW T. A three-phase unit with increased capacity.
A2WHPR32M/016T (Code 20191960): Hydro Unit M 016T, with a power size of 16kW T. The largest three-phase unit listed, designed for substantial heating and cooling requirements.

The "A2WHPR32M" prefix in the description likely refers to the product series, possibly indicating "Air to Water Heat Pump R32 M" (R32 being a common refrigerant type), suggesting it's an air-to-water heat pump system. The numerical suffixes (004, 006, etc.) directly correspond to the nominal power output in kilowatts. The inclusion of both single-phase and three-phase options highlights the product's adaptability to various electrical infrastructures and load requirements.
