CHD. The automatic dispensing system for all liquid chemicals and auxiliaries. By the THEN chemical dispensing system CHD chemicals and liquid dyestuffs can be dosed in quantities from 50 ml to several 100 liters from the chemical room to the individual apparatuses. Owing to the compact design and the use of pumps, you are independent of space conditions, by which a simple and cost-efficient installation is achieved. The liquids are volumetrically measured via two flowmeters and transported to the apparatuses by means of a pipe system. By the use of compressed air as a transport medium the water consumption is definitely minimized. Owing to the reproducible dosing accuracy, a reduction in the quantity of chemicals and of additional quantities is achieved. Apart from that the contact of the operating personnel with chemicals injurious to health is avoided. Each CHD module is completely mounted on a stainless steel frame and includes: Collector module for the connection of the chemical tanks to the pipeline system Transport pump PLC controller with Profibus connection (L2-DP) Rinsing water connection The system can be used as a standalone-system or be integrated into an existing EDP-system via interfaces to all common recipe formulation and control systems. The decentralised controlling system with field bus-interface and the variable, individual layout of piping make an extension of the distribution system with additional machines very easy. Functions: Fully automatic dosing of liquid products Short call-off times and high flow velocity Up to 56 chemical tanks can be connected, which means up to 56 products per line Taking the product-specific flow properties into account Data transparency through OPC-server and PC Expanded diagnosis through the use of SoftSPS (WinLC) Well arranged representation of system parameters (switched valves, etc.)
