Ecoline Reciprocating Compressors with IQ Module
Ecoline reciprocating compressors offer maximum energy efficiency in full and part-load and are designed for a wide range of applications such as supermarkets. They off er high freedom in the selection of refrigerant, including R1234yf, R1234ze(E), low-GWP blends and natural refrigerants. The intelligent IQ module leads to high energy efficiency. In combination with the Varistep mechanical capacity control, users can infi nitely adjust compressor capacity between 10 and 100 per cent – a true alternative to frequency inverters.

OS.A95 Screw Compressors for Ammonia
The energy-efficient OS.A95 screw compressor series is suitable for ammonia applications. The natural refrigerant has zero global warming potential and does not damage the ozone layer. Their cooling capacity and automatic Vi adjustment make OS.A95 screw compressors suitable for a wide range of applications in air-conditioning, medium and low temperature systems as well as in heat pump applications. A key component of the OS.A95 series is the integrated double slider, which can be used to infinitely adjust the compressor’s cooling capacity and internal volume ratio within a wide application range for greater efficiency. The integrated IQ module enables precise, stepless compressor control in accordance with the requirements of the superior system controller.
