Our Goal

Heating is colloquially considered a luxury, and more in a country like Mexico, where the heat is taken as a daily. But when it comes to specialized industrial processes or performance and production in greenhouses, heating is not a luxury, it is an absolute necessity.

And as part of an industrial process, not a question that can be left to chance, is a matter of vital importance that may mean increasing the profit margin of a company, or total loss of investment in it.

Understanding this fundamental need, in Van Triest Engineering Group works to give the customer not only products of the best brands with proven quality, but also the necessary technical support for users who decide not see your confidence in your investment risk.

The mission of Van Triest Engineering is to provide the best product, best support and better care.

Zirkonium-dioxide probe (current probe) for a continuous measuring of oxygen concentration, in a range Lambda > 1 without special gas conditioning, in combustion gases, industry exhaust gases and in oven atmospheres.

Lambda-probe LS1 combined with Lambda Transmitter LT1 forms a system for direct and continuous measuring of O2 concentration.

Applications:

  • Industry and power plants of all kinds Approved by German Technical Inspectorate (TÜV)
  • Federal Immission Control Directives (BlmSchV) 13. and 17.
  • Optimised combustion
  •
