E CLEAN EXHAUSTSWITH ECS PURIMUFFLERS

Catalytic Purifiers have been known and accepted for some time as an efficientmeans of cleaning up gases in exhaust streams that are either toxic, noxiousor both.

All internal combustion engines emit hydrocarbons as unburnt fuel and carbonmonoxide. Hydrocarbons can cause bad odours whilst carbon monoxide can causeharmful effects ranging from headaches to death at I000 parts per millionafter 2 hours. Regulations of many Governmental departments require CO levelsto be less than 50 ppm and often 35 ppm 3n the working environment.

Even with reasonable ventilation these levels can often not be achievedwithout some form of emission control. By combining the unwanted gases withair and passing over a catalyst at operating temperature a high proportioncan be removed to carbon dioxide and water.

It has previously been acceptable to replace the muffler with a purifier butwith present day regulations requiring increasingly lower noise levels, thesilencer often can not be removed and still meet the required decibel level.

The effect of these new requirements is to increase the complexity, time,cost and problems of installation. In some cases it is just not possible toinstal a purifier and a muffler.

ECSoffers a range of muffler/purifiers which are designed to replace theexisting muffler. Simply unbolt the original muffler and replace it withan ECS Purjmuffler.
