Heat Recovery

Why Recover Exhaust Energy? A typical reciprocating engine is roughly 30% efficient, meaning 30% the fuel energy input goes to generate shaft horsepower. The rest of the energy is given up as heat, with typically 30% lost to the exhaust, 30% to jacket water cooling of the engine, and 10% to radiation and other losses. […]

Process Silencers

Controlling noise especially in industrial process manufacturing plants is not easy. Machinery such as large or small high speed positive displacement blowers, industrial fans, low pressure vents, centrifugal compressors, gas turbine engines, centrifugal blowers, vacuum pumps, etc. require noise control measures to meet a facility’s sound abatement requirements. As part of our product portfolio, we […]


The AT-IV Active system is a unique product designed for diesel engine gensets in the range of 500 kW to 4 MW employed in mission critical installations such as hospitals, data centers, financial institutions, and drilling rigs, or for engines operating in extreme temperature applications. The AT-IV system’s single housing assembly is modular and can […]

Some of the components within the systems include: – MIRA-MONITOR (PC Based System) – Analysis Controlled Injection System (SCR Controls) – Diesel Particulate Filter (DPF) Monitor Depend on MIRATECH to help you be more efficient in monitoring your emission […]

ACIS (SCR Controller)

This analysis controlled injection system measures the NO–concentration in the waste gas. Based on this measurement the amount of reactant to be injected into the waste gas channel is calculated. The NO-concentration for this closed loop control is continuously measured after the SCR-catalyst. (The emission monitoring values are updated every five minutes.) That makes it possible […]


The reliable, cost-effective MIRA-MONITOR provides users with a Continuous Parametric Monitoring System (CPMS) and helps gas and diesel engine users meet RICE NESHAP requirements by providing complete catalyst monitoring for total control over regulation compliance. Federal regulations adopted by U.S. EPA on March 3, 2010 require many owners and operators of non-emergency generators equipped with […]
