Sometimes you can see disaster coming from a mile away, but often it’ll show up at your doorstep uninvited. One night in Boston, an over-pressurized water main broke, causing severe flooding throughout one of the city’s streets. Once the water had dissipated, crews scrambled to fix the pipe and restoration professionals began assessing damaged buildings. As it turned out, damage had reached one above-ground building and one below-ground building, leaving about five feet of water damage. The restoration contractor knew that moisture had to be drawn out within 72 hours to stop the growth of mold, so they needed a swift and responsive partner to provide a rental dehumidification solution. Thankfully for them, Mobile Air & Power Rentals was ready to get the job done quickly.
Knowing that time was precious, a sales representative arrived at the site within an hour to design a solution that would include rental heaters and rental dehumidifiers to draw moisture out of the buildings. Working through the night, the MAPR sales team designed a solution and drafted a proposal for the customer. The next day it was approved by the customer. The solution called for heat, dehumidification, and all the accompanying power and accessories to support the job. Delivery of the equipment started three hours after the proposal was approved, and technicians began their installation immediately. The equipment was completely installed by the next day, less than 72 hours after the flooding incident.
It took teamwork, determination, and perseverance to effectively handle this emergency. Thanks to the abilities of Mobile Air & Power Rentals’ sales and operations teams, the restoration contractor was able to it the ground running.

It goes without saying that methane is a crucial and versatile chemical used all across the country. It’s used for heating homes, generating electricity, fertilizing soil, and a host of other applications. Manufacturers of methane gas must continue their operations to provide a consistent supply of the substance, which means that any potential disruption must be dealt with immediately.
One manufacturer in Arizona had purchased a new chiller a few years back, only to find that it was beginning to fail and might completely break down before the end of the summer. The chiller was used for process cooling, and without it they faced a potential halt in production that could spell disaster for their operations. After researching the merits of buying vs. renting a chiller, the manufacturer decided that they needed a reliable partner to provide a rental chiller and to handle everything else through a full turnkey solution. When they contacted Mobile Air & Power Rentals, we were more than prepared to design, install, and service the solution they needed.
Once the facility and its cooling needs had been assessed, a sales representative designed a solution that called for a 440-ton air-cooled chiller. The chiller was promptly delivered to the site, and a manager and two technicians installed the rental chiller and its ancillary equipment in less than a day. However, in addition to commissioning and startup of the equipment, the manufacturer also required a certain amount of glycol in the chiller’s water to keep the temperature even lower than usual for their process cooling. This required extra care and setup to prevent any spillage of glycol into the surrounding environment, but it was no challenge for MAPR’s experienced technicians.
The timing of the installation couldn’t have been better — by the time the rental unit was installed, the manufacturer’s permanent chiller had just broken down. Having saved their operations, the rental chiller is set to stay at the facility until the end of the season, when outside temperatures will begin to cool. The chiller will receive monthly service, although the plant’s proximity to a rather dusty farm and Arizona’s monsoon season may warrant more frequent service than usual. With the chiller installed and a service plan in place, Mobile Air & Power Rental demonstrated once again its ability to provide turnkey solutions for any situation, regardless of the circumstances.

When a contractor begins the construction of a new building, there is almost no problem that can’t be overcome by its determination to finish on time. A common issue during winter construction is cold weather, which can hinder worker productivity, safety, and even certain processes like concrete curing.
One general contractor in Baltimore faced the limitations of a harsh winter and wanted to provide heating to its job site, but there was a significant drawback preventing it from doing so: there was no 460-volt electricity supply to power heaters large enough for the site. The contractor needed more than just a company that could rent out heating equipment, it required a partner that was ready to provide everything necessary to keep construction on track. The company contacted Mobile Air & Power Rentals, who was more than willing to take on the challenge. For Mobile Air & Power Rentals, this was our first chance to showcase our new versatility since the acquisition of American Equipment Group, or AEG.
The particular needs of this contractor called for a joint venture between American Power Rental (a division of AEG) and Mobile Air & Power Rentals. Mobile provided the necessary heating equipment for the job, and American Power Rental provided the generators to power the equipment. Two technicians and two sales representatives from both divisions spent a day installing equipment for the site. Mobile Air & Power Rentals provided four direct fire heaters, two rated at one million BTU and the other two at four and a half million BTU. To power these heaters, APR brought in two 45-kVA and two 70-kVA rental generators.
With all of the equipment installed, the construction site was ready to face the worst of winter in Baltimore. The contractor used the rental heating and power solution for about five weeks, with technicians servicing the generators once during that time. Thanks to Mobile Air & Power Rentals’ ability to accommodate any circumstances, this Baltimore construction site had the turnkey service it needed to finish the project on time.

As medicinal and recreational cannabis becomes legalized in more and more states, the overall popularity of cannabis, as well as related business opportunities, continues to grow. One such opportunity within the cannabis industry is the sale of biomass, or harvested organic material. Whether for use as fibre, fuel, or for CBD extraction, hemp biomass is proving to be an increasingly robust business venture for those who grow, process, and utilize the product.
That said, the endeavor is not without its difficulties. One business in the Gulf region, which processes harvested hemp in preparation for use as biomass, needed a temporary drying solution for the warehouse where their hemp is hung and dried. Normally their hemp is naturally dried on its own, but a busy season made it necessary to accelerate the drying process. Knowing that it was critical to choose a partner who could design and install an innovative solution like no other, the business called on American Spot Cooling to help them out.
Although the hemp biomass sold from this processing plant can be used for numerous applications, its quality needed to be suitable for CBD extraction. This means drying the product to a specific moisture content that produces the most oil during the extraction process. As of right now, most leaders in the rental equipment industry are scrambling to find the standard for hemp drying solutions, but American Spot Cooling is known to think outside the box and find the right solution, which is why we got the call. One of our drying specialists designed a unique solution for the warehouse that was powered by our rental generators. Once the rental HVAC equipment was prepared and loaded onto trucks, two installers punched in the coordinates of the plant and set out to install ASC’s industry-leading drying solution.
After a day of installation, the warehouse was equipped with the right combination of machines to provide ideal atmospheric conditions for producing the desired moisture content in the biomass. The processing plant used the rental drying solution for about a month and a half, long enough to prove that ASC's design had worked just the way it was planned.

At any hospital, an operating room must meet certain temperature and humidity conditions for the sake of patient health and safety. Keeping the space cool and dry limits the growth of bacteria and thus the possibility of an infection. These requirements are a problem for many older hospitals, whose dated cooling systems struggle to keep up with the demand. One hospital in Oklahoma was not meeting the necessary conditions for their operating room, and was at risk of shutting the room down if proper temperature and humidity could not be restored soon enough. They decided to hire an engineering firm to install new HVAC equipment in the hospital, who had, in turn, called American Spot Cooling to implement temporary cooling in the meantime.
By using psychrometrics and airflow calculations to better understand how temperature, humidity, and air flow affect each other in the operating room, an ASC sales representative engineered a solution for the hospital. The plans were approved by the firm, and equipment was delivered within a week. A member of the American Spot Cooling management team then went to assist a mechanical contractor in a semi-permanent installation of the site.
To provide the necessary temperature and humidity control, two 30-ton air conditioners, a 1,500 CFM desiccant dehumidifier, and a variable frequency drive was installed on the hospital roof. The units were brought up to the roof via crane, connected to hard ducting, and wired into the hospital’s automation system. Permanent equipment was installed in November. Until then, the rental air conditioners and rental dehumidifier served the strict condition requirements of the operating room for just over a year in total.

Considering the massive population of a highly developed planet as well as the widespread presence of online shopping among American consumers, it’s no surprise that shipment facilities are known to be hectic, where the nonstop work can be crippled by any delay. One such facility in Boston faced potential disaster when their water cooling system broke down the weekend after Independence Day. Their chiller system consisted of two distinct halves. One half of newly installed chillers that were not yet ready for use, and the other half was a chiller from 1975 that was on its last breath. When the old chiller broke down, the facility called American Spot Cooling and Power Rental for emergency service, and a representative arrived on site Sunday morning.
The representative determined that the old chiller had about 800 tons of cooling power, and then presented an engineered solution to the facility. With a 4:00pm approval of the rental agreement, the equipment was delivered by 6:30pm. Because of the immediate demand for cooling, four nearby 200-ton chillers were used, as opposed to waiting for a larger unit from other branches around the country. Otherwise, hundreds of employees would risk overheating at work and the facility would face a shutdown until cooling was restored. The permanent chiller system used 13,000 volts, so rental generators were also supplied to power the rental chillers. A 1000 kW unit and a 500 kW unit thus accompanied the chillers, and the equipment was installed overnight; within 12 hours of delivery the temporary cooling system was up and running.
Three technicians, a service manager, and an operations manager facilitated the install. They made sure to take extra safety precautions on the job, such as craning equipment and running 1000 feet of hose to the rooftop mechanical room. A mechanical contractor was then hired to remove the piping from the broken chiller, then to tie in the rental chillers to the system. After the installation was complete a technician made daily onsite inspections of temperature and liquid flow, until the facility could finish installing their new permanent system. Once the new chillers ran without fail for 24 hours, American Spot Cooling and Power Rental was able to pull out their temporary cooling and power equipment.

Each year, one grocery distributor hosts a charity event for the Special Olympics, where proceeds are donated to the organization. The year end festivity for the fundraiser features many different attractions, such as a car show, chili cook-off, petting zoo, and amusement rides. Most importantly, the event takes an opportunity to honor Special Olympic athletes, both in attendance and not.
For each year’s event, American Spot Cooling and Power Rental is called upon to consistently provide the festivity with rental air conditioning and power. With a total of about 60,000 square feet of tented area, ASCAPR keeps the events going and the attendees feeling comfortable. Between all of the tents there are 21 25-ton rental air conditioners installed over the course of three to five days, along with several hundred kilowatts of power from multiple rental generators. Throughout the duration of the event, technicians monitor and maintain the equipment to keep attendees cool and happy.
This is one of ASCAPR’s most important (and favorite) yearly events. Not only do we demonstrate our ability to provide rental cooling and power service to an event type application, but we also get to help support the Special Olympics and show appreciation for its athletes.

When a company was faced with the constraints of two new pump stations hundreds of miles apart, one gas line, and no room for interruption of pump service they reached out to American Power Rental hoping to find a solution. They had finished constructing their gas pipeline pumps ahead of schedule, and needed a temporary power supply until local utilities could install a permanent source of power to the stations. Fortunately American Power Rental excels at thinking outside the box and was able to engineer a turn-key solution that fit the exact needs of this company.
After days of planning, American Power Rental facilitated the set up of two job sites simultaneously. Using an eight person team, consisting of our most experienced technicians, management, and engineers, each site was built without a glitch.
At each site, technicians installed five (5) paralleled generators, each rated at two (2) megawatts, providing a total of eight (8) megawatts of primary power with two (2) megawatts on standby. The rental generators were supplied by onsite rental fuel tanks with a 3 day run capacity, and both the generators and fuel tanks were protected by containment berms. Several miles of camlock cable brought the power through a 3,000 amp disconnect to a pair of step up rental transformers, where the 480 volt line was converted into the 4,160 volts needed to power the gas pumps.
Although this is a temporary setup, the pump stations are expected to utilize the rental power distribution for months and American Power Rental will continue to provide service to these sites as long as necessary. Technicians will monitor and maintain the sites 24 hours a day, and their onsite expertise will provide uninterrupted liquid gas pumping until local utilities can establish stable line power.
10 August 2018When a customer called early in the morning with a problem that needed to be solved quickly, the American Spot Cooling and Power Rental team was ready to roll. The problem was that the concrete the customer was pouring was out of specs due to being too high in temperature. We arrived on site within the hour of the call, assessed the situation, and calculated a solution. We then were able to get equipment on site within the same day and operational the following day. The ASC/APR team utilized a 60 ton chiller along with taps that the customer installed on his tank, allowing the concrete to be within specifications and the customer to continue performing their work.

American Spot Cooling received a phone call from a large regional hospital on the east coast of Florida that was experiencing mechanical failures to multiple chillers through out the facility causing the chilled water temperature in the building to rise. Although a competitor of American Spot Cooling and Power Rental had promised a rental chiller they suddenly couldn’t deliver at the last minute. Fortunately, our Florida sales representative was able to line up a 400 ton air cooled chiller right away, and within 6 hours of the initial call the hospital was back up and running - despite the space constraints calling for tight positioning of the chiller and space to run hose without blocking hospital egress.
