MK-System in Transport Refrigeration Unit (TRU) Applications

Operation of the MK-System (trailer application)

The filter becomes loaded with soot during reefer operation. While the engine is running, the backpressure is rising as the soot accumulates in the filter. The HUSS control monitors the status of the filter continuously. When the maximum backpressure set-point is reached, the HUSS control automatically shuts of the reefer engine and initiates the regeneration cycle. The regeneration takes about 20 minutes to finish. After the regeneration sequence is completed, the HUSS control re-starts the engine so that the clean filter may begin collecting soot again.

Operation of the MK-System (bobtail application)

The filter becomes loaded with soot during reefer operation. While the engine is running, the backpressure is rising as the soot accumulates in the filter. The HUSS control monitors the status of the filter continuously. When the maximum backpressure set-point is reached, the HUSS control alerts the driver that the filter needs to be regenerated. The sequence is initiated by turning off the reefer engine, pressing a button to power the HUSS MK-system, and pressing the Start button of the controller for 5 seconds. The regeneration takes about 20 minutes to finish. After the regeneration sequence is completed, the driver may re-start the engine so that the clean filter may begin collecting soot again.

Advantages of the MK-system in TRU Applications

absolutely independent from exhaust gas temperature

the filter regenerates reliably, with no regard for the exhaust gas temperature generated by the engine

more than 85% filtration efficiency

more than 85% of the harmful soot particles remain in the filter and don’t reach the ambient air. This is designated as a CARB Level 3+ device

verified and proven

The MK is approved by VERT and CARB, is part of the BAFU and MSHA list and fulfills the requirements according to TRGS554

completely independent operation

does not require an external power supply, no catalyst coating needed, no manual filter swapping for external regeneration, simply regenerate automatically (trailer) or while safely parked (bobtail)

robust design

the filter modules are made of stainless steel. The entire system is designed for longevity and realibility

wide engine range

we offer systems for both trailer mounted as well as bobtail applications
