HEAT EXCHANGING FOR THE EARTH A heat exchanger is designed to transfer heat from one fluid (liquid or gas) to another without contacting one other. Heat exchangers are used in commercial, residential and industrial applications to facilitate thermal energy exchange, and they can have several positive environmental impacts. By reusing heat that would otherwise be […]

As summer heat temperatures continue to rise, Power Mechanical is prepared with a fleet of chillers to assist your company’s needs!  A chiller is a mechanical system used to cool fluids, usually water or a water glycol mixture, for an array of applications. Chillers are commonly used to maintain a specific temperature range for providing […]

When we’re not building boilers or delivering your next mobile boiler room, the troops at PMI are looking for more ways to serve.  Did you know that the 2022 holiday season marks the 75th anniversary of the Marine Corps Reserve Toys for Tots program? This program has delivered hope and the magic of the Christmas […]

The commercial boiler used in your facilities provides various functions. It may provide hot water or steam for workstations, processes, HVAC, heating systems, and other applications. Without the boiler, you will not have the hot water or steam needed on demand. Unfortunately, you are now dealing with hot water issues. Maintenance and repairs on the […]

30 years ago an all-electric car would only be commonplace as a subject in a Popular Mechanics article, and highly unlikely to pass you out on the interstate. Today more than 20 million electric vehicles traverse the streets around the globe and the trend is expected to continue rising. Electricity has paved the way for […]

As summer etches forward, the hot topic of the year continues to be these fuel prices. With vacations being put on hold and commuters rethinking their daily driving habits, more and more people are looking for ways to save fuel costs. In the boiler room, cutting down on fuel expenses has been a longstanding objective. […]

Spring is the time of year that many plants begin planning and conducting annual maintenance on installed boilers and burners. Boiler combustion tuning is important to keep boilers performing their best through the changes in seasons. All combustion relies on fuel, heat, and air. It’s not often realized that combustion is no more than just a chemical […]

Steam is often a hot topic around here, after all, it is SteamNation! Yet boilers are at the crux of what most of our topics surround. Not all boilers however are steam boilers. While many facilities depend on steam generation, some boilers produce hot water for various purposes in industrial and commercial applications. At a […]

The last two years have been banner years for our Texas rental boiler market. One of our corporate goals for the year 2021 was to extend our rental fleet further into the Lonestar state. And as the old saying goes, “Go big, or Go home!” We went BIG during this period.  The last 24 months […]

The Boilers Gauge Glass The boilers gauge glass or sight glass as some may refer to it is an essential boiler room component. Boiler gauge glasses give operators a visual indication of the boiler’s water level along with an understanding of what’s occurring inside the boiler, or how the boiler is responding to certain changes […]

How to Optimize Boiler Room Effectiveness  At Power Mechanical Inc. there are two things that we love, building boilers, and building people. That being said anyone with even a short tenure around our company is quite familiar with many of the leading self-development titles like Zig Ziglar’s “See You at the Top”, “Think & Grow Rich” by renowned author […]

Boilers absolutely must be operated on level surfaces-  Seems a fairly obvious statement right? Boilers rely on being level in order to ensure both safe and proper operations. This is especially true with mobile boilers that are delivered and connected outside and then face changes in site conditions.  Surprisingly it’s not uncommon to find where […]

Combustion tuning of an industrial boiler is critical for continued efficient and effective boiler operations. When is the best time to perform a combustion tune of a boiler? First things first, there is no set standard on when a boilers combustion tuning needs to be performed. Daily monitoring of the burner’s performance will give operators […]

Oxygen present in boiler feed water is a killer for the tubes of a boiler. Water contains many elements that can either accumulate or erode the metal surfaces inside of a firetube boiler. Oxygen and Carbon Dioxide are present in most water sources and, when heated, the corrosive nature of these dissolved gases increases. As […]

Wintertime has arrived and it is in full force in many parts of the nation. With temperatures plummeting in many regions across the United States it’s critical to ensure that everyone is mindful of freeze protection. The winter months can bring brutally cold temperatures throughout many parts of the country. Areas in the Northeast where many rental […]

Redundancy is a term often used in mechanical and boiler room design. Redundancy is simply a reliability measure that is factored in when designing systems to ensure that should something fail, be in regeneration mode, being maintained or the like, there is a backup. Boilers rely on sufficient and reliable feedwater supply. Thus it is […]

A low water situation in a boiler is a potentially catastrophic situation. Data consistently supports that the majority of boiler accidents are a result of varying low water situations. When a low water condition begins in a boiler it can begin damaging the boiler even before there is an immediately noticeable problem. If the condition […]

Mechanical rooms rely on valves for numerous operations and processes. From boiler rooms, pump facilities, chilled water plants to simply valves for building zones, these components are critical for controlling fluids or gases to successfully operate. Different valves may have different maintenance and monitoring requirements. Incorporating all critical valves into a maintenance program will ensure […]
