TEHAG GmbH products

Extremely versatile and practical particulate filter system. Purely passive regeneration for exhaust temperatures from 230 °C (10 to 1 5 % load) without additional energy demand, control or additives. Very little space required both for original equipment und retrofitting. VERT* / LRV conformity, ABE, RDW certification and TR6S 554-compliant. Retrofitting subsidised by B6 Bau (DE). A reduction in particulate matter of > 99 %. Reduction of hydrocarbons (HC) and carbon monoxide (CO), at times below the limit of detection. Controlled monitoring of exhaust temperatures and counter pressure.

The »Active Wall-Flow HC-dosing« (AWF h) ) Particulate Filter System is a solution for vehicles and machinery that require low load profiles due to their areas of application and in which the exhaust temperatures repeatedly drop below the critical limits for purely passive regeneration. Depending on the vehicle or machinery application, the system au­tomatically starts regeneration of the particulate filter when the coun­ter­pres­sure exceeds a freely programmable value. During regeneration, the diesel is injected into the exhaust gas, which increases the temperature in the filter to around 600 °C. At these temperatures, the carbon contained in the filtered particulate matter reacts with the residual oxygen in the exhaust. This allows regeneration to work independently from the vehicle/machinery application, effectively eliminating downtime.

With the »Active Wall-Flow-electrics« (AWF-e) Particulate Filter System, we of­fer you a versatile particulate filter sys­tem for machinery and sys­tems that are operated regularly at a fixed location or within a limited deployment radius or for limited pe­ri­ods of time. These include lift­ing plat­­forms, municipal vehicles and in­dus­trial trucks, as well as stationary pow­er ge­ne­ra­tors. The filtered particulate is regenerated us­ing a heating coil that is integrated into the system’s inlet hood upstream of the filter element. The sys­tem is connected to an external power supply at the end of a shift, after deployment for a limited pe­riod of time, or when the filter mo­ni­­tor­ing system shows a cor­res­pon­ding mes­sage on the display. Once the system is connected to the mains, the re­ge­ne­ra­tion process can be star­ted.

Oxidation catalytic converters for combined heat and power plants (CHP plants), generators and drive motors.

The PTL filter monitoring is especially de­ve­lo­ped for constant functi­on mo­ni­tor­ing of diesel par­ti­culate ­fil­ter­ sys­­te­ms. The elec­tro­nical device measures the ex­haust tem­pe­ra­ture as well as the back pressure ahead of the fil­ter. To suit each vehicle type and effort, additional a mea­sur­ing probe for recording the num­ber of revolutions can be connected. By the default option the displaying of the ope­ra­ting states take place via a three-tone LED, which is installed in the cock­pit of the vehicle or rather engine. Possible mal­func­tions as well as the load status of the par­ti­culate fil­ter are able to be re­co­gni­zed im­me­dia­te­ly and can be eli­mi­na­ted by the dri­ver if ne­ces­sa­ry.
