PMRX系列吸热式气体发生器
PMRX-Series Endothermic Generator
吸热式气体，可用于低碳钢的渗碳和中碳钢保护气氛．此种气氛可用于光亮退火，正火和淬火．
The endothermic gas atmosphere, when enriched with natural gas, is suitable for gas carburizing and carbon restoration of the low and medium carbon steels. The atmosphere, as generated, may be used for clean annealing, normalizing and hardening of all carbon steels.
宝华威PMRX系列模块化吸热式气体发生器，采用模块化设计，产品系列由PMRX-50，PMRX-100，PMRX-200，PMRX-300等组成，额定产气量分别为50/100/200/300立方每小时。根据配置及产气量需求，设备由一根或多根反应管垂直安装在独立发生器内。反应气体是通过一套空气/燃气（天然气）混合系统按一定比例混合后的一种混合气体，此混合气体与反应管内的催化剂反应，产生如下成分组成的吸热式气体：
PowerMax “PMRX Series” modular design endothermic generators category are consisting of PMRX-50/PMRX-100/PMRX-200/PMRX-300 configurations, with corresponding endo gas output capacity at 50M3/H, 100M3/H/200M3/H individual module 100 m3/hour. According to output capacity requirement, the modular contains one to three vertical reaction retorts mounted in a rectangular designed and gas/electrical heating chamber. The gas atmosphere is generated by the endothermic reaction of an air/gas mixture in an externally heated retort containing a reaction catalyst. The approximate analysis of the resultant gas is as follows:

Endoinjector 混合系统 EndoInjector System
ENDOINJECTOR混合系统设计精密，用于控制发生炉在混合空气和燃气比率的精确性。由国外合作研发利用电子流量测量和精确燃气导入阀以持续性的导入气体进行混合，以此产生高质量的吸热性气体发生气。
燃气混合器拥有先进的技术，带有鼓风机的设计，使反应管得到最高的效用。实时监控软件连接时，根据实际用气需求量实时计算精确输出，实现发生器产气量自动调节，节能减排。
The EndoInjector is a precision gas mixing system designed specifically to provide an accurately controlled mixture of air and gas for endothermic gas generators. The system includes the Control-Carb gas control system designed by Atmosphere Engineering to utilize electronic flow measurement and precision gas injection valves to constantly provide the ideal gas mixture for high quality endothermic gas generation.
The EndoInjector incorporates the latest technology in regenerative blower design that is capable of significant turndown for multi-retort generators. When combined with the precise TrueTrim software, the EndoInjector delivers flow on demand throughout the working range of any generator down to 20% of rated capacity. This feature eliminates endothermic gas waste during production while maintaining the precise gas mixture required.
