Description

Located in Ottawa, Canada, VLN manufactures customized Water Jet devices for industry specific applications including aerospace, heavy equipment, power generation and automotive parts manufacturing. Specifically, we manufacture "forced pulsed and cavitating" water jet machines and Electro-discharge machines.

TST started developing Heat Protection equipment in 1990. We have thorough experience and a big network which continously gives us feedback on the function of our products.

VLN Tech offers several types of cavitating nozzles, the most advanced one being the so-called ‘reverseflow' cavitating nozzle. This nozzle not only functions better under fully submerged environment, it also works in air. Briefly, this nozzle consists of a central main high- speed jet surrounded by a stream flowing in the reverse direction. Both flows are taken from the same pump. This causes very severe turbulence in the interface between the two streams. As stated before, this turbulence is the source of cavitation. The nozzle can be custom designed for any application.

Are you looking for cooling garments that doesn't require neither electrical hook up nor batteries, or use strange chemical reactions? • You work in hot environments, maybe with complicated protective clothing? • You suffer from a disease which makes you feel worse in warm environments? • You want to perform at your maximum in a demanding sport? Our cooling products have energy elements, which absorb heat. They do it without having to provide any external energy!

An inveterate inventor, Dr. Vijay believed a high-frequency forced pulsed water jet could be developed for use in industries such as aerospace to remove coatings from aircraft parts and equipment. In 1998, after retiring from the National Research Council, Dr. Vijay founded VLN Advanced Technologies Inc. with the mission of developing and commercializing his new waterjet technologies.
