Top performance, minimum footprint
As demand for efficient heating rises, GEA RedAstrum is the standard ammonia screw compressor heat pump meeting that demand across a variety of applications. Known for its wide capacity range as well as its high temperature lift, it features high-end components and a sophisticated, compact design.
GEA RedAstrum 修订:第二代螺杆压缩机热泵提供优化设计、新的氨级联蒸发器选项和扩展的型号范围。该系列现在有七种螺杆压缩机类型,它们基于成功的 GEA Grasso M 和 GEA Grasso LT 系列,采用特定的高压设计。
GEA RedAstrum 与成功的 GEA BluAstrum 概念保持一致,并配备了根据每个项目的要求配置和优化的热交换器。它结合了可靠性、低氨气充注量和最小占地面积的优点以及适用于各种供暖目的的灵活性和效率。
GEA RedAstrum 将热量传递到液体热载体,以提供 +55 至 +80 °C 的供应温度,可用于需要过程热量或将热量输送到本地或区域供暖网络的任何工业应用。
由于在 -10 到 +50 °C 之间的低温侧具有宽广的温度范围,GEA RedAstrum 能够使用来自废水、地下水和地表水的任何热源;或者使用液体辅助制冷剂,用于冷热联供应用。或者,为了以最有效的方式回收废热,热泵可以配备级联蒸发器,该蒸发器直接从制冷设备充入热氨气。
*) 辅助制冷剂 +40/+35 °C,热载体 +40/+70 °C
