ALTISENSE

Overview

A CEMS is only as good as its sampling design, conditioning and data handling. We deliver CEMS as a specialist turnkey package, from the stack survey and sampling-point selection to shelter integration, DAHS and emission reporting, so that the system passes its quality assurance tests and keeps passing them.

How the system works

  • Continuously measures gaseous pollutants, dust and flue-gas conditions at stacks
  • Normalizes results to reference O2, temperature, pressure and moisture
  • Calculates emission rates and compares them against permit limits
  • Stores and reports data through a DAHS with audit trail
  • Supports furnace and combustion efficiency with O2 and flue-gas analysis

Turnkey scope. Stack survey, sampling design, analyzer selection, shelter integration, supply, installation, commissioning, calibration, DAHS integration, training and AMC, under one contract.

Typical system architecture

From the sensor in the field to the alarm on your phone: one engineered data path, designed, installed and supported by one team.
