FAQ: How Do Muira's LX and EX Series Models Differ?


Miura steam boilers are the best option for your company. They offer lower operating costs, excellent efficiency, and reduced fuel costs. There are several models available to meet your steam needs.

But are you wondering what the differences are between Miura’s LX Series and EX Series models? These top-selling steam boilers are both great choices, but it’s best to know how they differ to determine which option is right for your business or organization.

The LX offers a smaller footprint

The LX is a clean-burning industrial boiler that provides the smallest footprint per horsepower output between the two. In fact, with the LX, you can count on a boiler that takes half the space of a conventional fire-tube boiler and doesn’t require tube-pull space. The compact LX-50, 50 horsepower model, can fit through a standard doorway.

The LX features the lowest NOx ratings

Perfect for organizations subject to strict environmental regulations, the LX series offers naturally low NOx (nitrogen oxide) ratings. In fact, you can expect to see NOx levels as low as 9 ppm, depending on the model selected.

“LX boilers have the lowest NOx rating off the shelf of any manufacturer in the country,” explains Brandon Hargett of Boiler Masters Inc. in Greensboro, North Carolina, “and the newer LX lines at Miura have DFD control on their burners so they have better turn down now.”

The EX provides NOx ratings as low as 30ppm, also depending on the model.

The EX allows for dual fuel options

The EX offers flexibility with dual fuel options. Hargett states, “The EX series boiler is the boiler Miura has that's capable of burning #2 fuel oil as a backup fuel. So, you can opt for natural gas, propane, or #2 fuel oil. 

Design differences

While the LX series is known for its compact size, the EX series looks very similar to a fire tube boiler that has been turned up on its end — except it’s still made using Miura’s safe water tube boiler technology.

While the LX and the EX series may differ, both give you full steam in less than 5 minutes. Contact Miura today to learn more about our industrial boilers and ancillary products.
