Just a few years ago, there was a clear distinction between commercial and industrial refrigeration technology. Due to increasingly stringent environmental regulations and a growing demand for energy-efficient systems, ammonia (NH3) is increasingly finding a place as a refrigerant in the field of semi-industrial refrigeration technology. Due to its low global warming potential and relatively high enthalpy of vaporization, ammonia has become indispensable in many applications and represents a future-proof solution. To switch to natural refrigerants, skid manufacturers and contractors need components that simplify handling and implementation due to their low complexity. A multipack application is used as an example to show how semi-hermetic compressors can simplify the switch to natural refr ...
