JP Jensen Ventilation, formed in 1879, is one of the oldest companies in the world specialising in processing PVC-coated material. JP Jensen’s wide range of services includes everything from ducting system planning and assistance with installation, to reconditioning. Customers may choose between buy, rent, investment or logistic solutions.
Amongst the product range is JP Superjoint – a patented coupling for ductings, to ensure straighter airflow and airtight systems. The speed of the air changes if the cross-section of the ventilation canal changes, as is the case with traditional steel couplings, zip and carbon couplings. It is also certified that the same ducting connections have a leakage of different grades. Changing the speed results in an alteration of the dynamic pressure, with consequent loss of energy. A straighter and tighter tube in the coupling area leads to better results at the end of the ventilation canal and reduced costs for high kW performance.
JP Superjoint is a patented solution for creating a straight airflow in a flexible ducting. This is a unique solution designed to eliminate the two most common energy thieves in the underground ventilation system, airflow (turbulence) and leakage in the joints. Depending on the size of ventilation system, the JP Superjoint offers savings in the range of 10-20%.

Lubrizol Engine Control Systems (ECS) is pleased to offer the Combifilter, an electrically regenerated diesel particulate filter. The Combifilter is comprised of an integrated diesel particulate filter and silencer assembly and a regeneration station. The filter assembly typically removes >90% of diesel particulate (PM) from the engine exhaust. The filter particles (soot) are stored in the filter centre body until the filter centre body is regenerated.
Regeneration is a process by which the loaded filter centre body is heated to the temperatures necessary to burn the collected particulate into trace amounts of inert ash, thereby renewing or regenerating the filter centre body and maintaining an environmentally safe workspace.
The filter assembly can be further combined with an AZ oxidation catalyst for the reduction of the gaseous pollutants CO and HC. ECS designs and manufactures the Combifilter to effectively reduce Particulate Matter (PM) from mining, materials handling, off-road, and on-highway vehicles. The Combifilter has been evaluated by numerous global governing bodies for verified emissions reductions.

Neotronics

Neotronics claims that its new Impact gas detector stands above the competition due to its ease of maintenance and calibration.
The Impact utilises an intelligent cartridge sensor system having a life of 12-18 months. When expiry of the cartridge is indicated by a calibration failure it is simply replaced and the instrument re-calibrated.
The Enforcer calibration accessory is a portable device into which a canister of traceable test gas is screwed. The Impact is simply clipped into the Enforcer and, at the touch of a button, calibration commences. In under two minutes, calibration is complete and the Impact will indicate pass or fail accordingly. The controlled exposure also greatly reduces test gas wastage with approximately 200 calibrations available from each canister.
The company claims that the combination of cartridge based sensors and the Enforcer calibration system drastically reduce running costs and downtime, ensuring that the Impact is available when required.
