Danfoss Maneurop® inverter reciprocating VTZ High Precision and Cost Effectiveness at the Core of your Process Danfoss Maneurop® - VTZ reciprocating inverter compressors 11 – 166 kBtu/h multirefrigerant units R404A, R407C and R134a - for commercial and process cooling applications prevent you from oversized and short cycling systems by automatically adapting to the current load in your commercial package air conditioning, chillers and rooftops. Use the compressor package that utilizes variable speed technology. ±0.3°C precise and stable temperature control improves process and equipement reliability

Refrigeration compressors are normally selected to correspond with maximum expected system loads. Since loads vary throughout the year, the compressor designed for maximum loads turns out to be oversized during long periods (it has been estimated that on average systems are running partially loaded at least 85 % of the time). The conventional regulation systems used for compensating this excess capacity are on / off controls, pressure regulation unloading valves or hot gas bypass. In comparison with these methods, the Danfoss variable speed VTZ Compressor Drive TM offers a superior, innovative...

2- One qualified “plug & play” solution Reduced set up time and lower installation costs No need to select the appropriate drive to the compressor: the solution is prequalified and you get easily your code for ordering. Lower installation and commissioning time: the drives are factory preset in all parameters to run with an external 0-10 V signal and for optimum performance on the whole VTZ Compressor DriveTM range. Many integrated functions for reduced costs in additional equipment Smaller cables and electric devices ratings & lower electrical power supply contract: the built-in soft starter...
