Fricke und Mallah-我们加速您的干燥和加热过程
我们的座右铭我们加速您的干燥和加热过程自公司成立以来一直是我们的核心使命。了解并加速烘干和加热过程，以使我们的客户能够尽可能高效地生产，这是我们的日常实践。
英博士。德克-H。弗里克和迪普。-ing。Marcel Mallah以高频技术为重点学习电气工程，随后在科学和工业环境中获得了经验。
1995年，他们决定成立Fricke und Mallah微波技术有限公司。从那时起，Fricke und Mallah已经成为工业和研究的可靠合作伙伴。
我们已经为木材、陶瓷、塑料和食品工业制造了高质量的微波系统，微波功率高达1兆瓦。这包括微波加热系统，其中微波加热室可以完全电动提升，以允许100%的清洁和维护。所使用的微波发生器和天线，其额定功率可达20千瓦，均由内部制造。其他活动包括电力电子学和微波专用测量技术的发展。
在我们的电磁场和温度场深度建模专业部门，7名高频工程师主要使用CST®和COMSOL®软件，以有计划的方式通过有根据和逼真的模拟使客户和研究项目成功。他们补充我们非常有效和创新的机械和电气设计部门。
一个微波测量站、一个电磁兼容室和许多微波实验室烤箱和温度测量设备可用于初步研究和开发任务。与汉诺威大学电热过程技术研究所也有密切联系，该研究所密切参与热场和电磁场的模拟。
同时，我们是世界领先的微波发生器和系统（加热和等离子体系统）的制造商之一，基于固态微波技术。目前，我们生产和提供基于固态微波技术的微波发生器，功率范围为250瓦-6千瓦，频率范围为915和2450兆赫。我们的固态微波发生器配备了特殊的技术智能，用于自动和非常快的功率调整和均匀的场分布。这些发生器可以与紧凑的RF组合器相结合，允许在单个端口上产生更高的微波功率。固态微波发生器的特点是自动电子功率匹配（不需要更多的机械3根调谐器！）不到几毫秒。
在磁控管技术领域，Fricke和Mallah提供单独的微波组件（波导、调谐元件，如手动和电动三根调谐器、隔离器等）和适当的电源，此外还提供定制的紧凑型封装磁控管头。我们的低纹波开关电源在2 kW/2.45 GHz，3 kW/2.45 GHz，6 kW/2.45 GHz和5 kW/915 MHz非常适合监测和控制所有重要的磁控管工作参数，如高电压和高电流。这保证了磁控管始终工作在理想的工作点（更长的寿命）。
作为建筑扩建的一部分，2016年生产面积增加了1,250平方米，而办公大楼占地1,200平方米，共3层。技术扩展包括生产大厅的完整Bekranung，以及高达1兆瓦的电力供应。这使得安装功率高达600千瓦的微波系统可以在连续运行中进行测试。
Fricke und Mallah微波技术GmbH是德国领先的微波炉供应商之一，该公司拥有40名高素质的员工。
