Haldex recently announced that the new Multi-Treatment Cartridge Plus (MTC+) will soon be offered as standard on all Haldex DRYest and PURest air dryers. The coalescent filter on the outlet passage of the patented MTC+ removes 40% more of the fine oil and hydrocarbon particles from the air system than competitive air drying cartridges, Haldex claims. Once the air has passed through the desiccant bed of the cartridge, the coalescent filter removes the oil particles remaining in the air stream.
At the same time, the MTC+ is said to remove more than 99% of contaminants from the system, effectively eliminating oil while still maintaining its high adsorption capability. Using a five-stage process to deliver dry, clean air, the new cartridge is claimed to give three
times the drying capacity of competitive air dryers.
This drying capacity does not impede air flow, says Haldex. By preventing oil contaminants from building up in the air system reservoir, the MTC+ ensures adequate air volume is available for system components downstream of the dryer. This reduces corrosion and freezing problems caused by inadequate air flow, and reduces the opportunities for oil contaminants to migrate to the air valves and other brake components.
The new cartridge is also said to last longer, and instead of a spin-on mount, a four-bolt slide-in and -out design allows for quick replacement while the air dryer is still on the vehicle. Available on all new Haldex DRYest and PURest Air Dryers, the MTC+ will fit directly in the applications of the MTC with no modifications necessary to DRYest and PURest Air Dryers already in operation.
