Filtering dust by inertia

  Current industrial filtration methods often require costly maintenance, and filter membrane replacement on an ongoing basis. Tshwane-based Rand Technical Services (RTS) offers robust, highly-effective inertial spin filter technology for industrial dust and exhaust separation, which is virtually maintenance-free. Spin filter units are a high-efficiency application of cyclone technology. Air to be separated is blown […]

Combined dust sample probe improves measurements

  Durag’s D-RX 250 combined sample probe is used for continuous monitoring of dust concentrations in flue gas ducts, dust extraction pipes and similar applications. Besides measuring dust concentration, volume flow and temperature, the absolute pressure in the flue is also measured. These measurements enable the figures to be converted to normal conditions. The combined […]

Raw coal sampling system

When monitoring the efficiency of a combustion process, it is important to know and understand the nature of the coal being burned. Generally, a proximate analysis will include the following: heat value; moisture content; hardness (Hard Grove index); sulfur content; ash content and volatility. These parameters are essential when optimising the combustion process at coal-fired […]

Low voltage motor protection relay

The NewCode relay from NewElec is an ISO 9001:2000 compliant, locally designed and manufactured three phase electronic motor protection relay. The relay is fully configurable with the aid of free front-end software or a man-machine interface unit (MMI). An on-board data base stores fault and event records, which are date and time stamped. The front-end […]

Distributed control system for small to mid-size process applications

Honeywell recently announced the release of Experion LX, a purpose-built distributed control system for small to mid-size operations with continuous and batch process control applications.
