Canadian company ready for stricter Tier 4 Canadian emissions regulations

April 8, 2016 | By Rehana Begg

Hunter_Ultrasonics_-_April_2016_release_imageToronto – Canada’s Off-Road Compression-Ignition Engine Emission Regulations now have stricter standards than those first introduced by the Government of Canada in 2006. The Regulations have now moved to Tier 4, which now requires all off-road, commonly known as “nonroad” vehicles to be fully complaint in Canada by 2018. And, if your vehicle operates in the United States, the EPA is mandating Tier 4 compliance even sooner – by the end of 2016.

Hunter Ultrasonics, a Canadian-based company, is uniquely positioned to help all nonroad equipment owners maintain their exhaust systems within these tougher Tier 4 emission regulations. The company’s patent pending ultrasonic cleaning equipment, which is assembled in Canada, is currently set-up to handle the specific large filters used by nonroad equipment and vehicles.

Ken Hunter, founder of Hunter Ultrasonics, who has been a leader in industrial ultrasonic cleaning since 2010 says, “For the Tier 4 nonroad equipment requirements mandated by the Canadian and United States governments, we have developed a patent pending technology and are the only provider in the Canadian market currently able to service all our customers’ nonroad needs. This includes maintaining not only diesel particulate filters (DPFs), but also a whole range of components including exhaust gas recirculation (EGR) coolers and diesel oxidation catalysts (DOCs). We pride ourselves in developing solutions that save our customers time and money.”

Hunter Ultrasonics can handle components from all types of equipment including excavators and other construction equipment, farm tractors and other agricultural equipment, heavy forklifts, airport ground service equipment, and utility equipment such as generators, pumps, and compressors.


Ultrasonic cleaning, or “sound wave” cleaning, is the safest and most non-invasive way to clean ceramic DPF’s. Working at a microscopic level, the equipment uses cavitation bubbles to blast away any fouling. The benefits are:

Harmless to soft metals like aluminum and brass
Harmless to other materials like plastics, rubber, fibre gaskets, and glass
Thermal cracking is completely eliminated
Removes, dirt, oil, grease, lubricants, and carbon
Multiple filters can be cleaned at once reducing down time
Filter substrates are safe from high pressure air knives
Uses green environmentaly friendly cleaning solutions
