GEA RedAstrum – the compact heat pump solution for industrial uses and for local heat distribution networks

geaWith its new GEA RedAstrum series, GEA offers a highly efficient, standardized ammonia heat pump solution for indoor installation in industrial uses and local heat distribution networks. Distribution of heat to the users takes place via a water cycle. Heat exchangers, as they are already used in the efficient GEA Blu chillers, assure excellent heat transfer from the ammonia medium to the heating medium.

The heat pump provides heat at a temperature level up to 80 °C: which also makes it effective for preparation and supply of hot water in industrial processes.

Powerful and space-saving: the new GEA RedAstrum heat pump series

With its four model sizes, the new RedAstrum series covers the range of approx. 1 to 2.5 MW of maximum heating duty, with temperature increase of 40 to 70 °C and with a heat source at 40 °C. The GEA RedAstrum operates effectively in conjunction with sources that provide heat in the range of 10 to 40 °C.

Maximum efficiency is assured by quiet-operating, speed-controlled screw compressors from the GEA Grasso M series that are designed for application at pressures up to 52 bar and that demonstrate an optimal internal volume ratio. The typical rotor profile plays a key role here for the high energy efficiency of the RedAstrum. In addition to speed control, these compressors are equipped with continuously variable output slide control, which enables extremely low part-load operation as well as soft starts.

Its compact, narrow design (unit width of 1.4 or 1.6 m) and small footprint enable the GEA RedAstrum to be easily installed in existing machine rooms. As a result, it is exceptionally well suited to replace conventional heating systems. The RedAstrum is delivered in one piece, ready for connection, and comes from the factory with the GEA Omni™ control system, which can be quickly and intuitively operated with a color touch display by operating staff and service technicians.
