Applications
The ECA 450 is ideal for professionals concerned about
combustion efficiency, environmental compliance, or both.
It enables plant maintenance engineers and managers,
industrial boiler/furnace service technicians, energy
coordinators, compliance officers, environmental auditors
and safety managers to ensure that industrial equipment is burning
efficiently while environmental regulations are being met.
