GP Energy Products · Service & Emergency Response

A boiler failure in the middle of winter is not an abstract problem. It is a building full of people without heat, a production line that cannot run, or a facility that cannot operate until steam is restored. The question is not whether you need a solution. It is how fast you can get one on line.

GP Energy Products maintains a rental fleet of boilers and heat exchangers specifically for these situations. From a 34 HP dual-fuel unit for a smaller commercial application to a 350 HP outdoor-construction Sellers for a facility that needs high-pressure steam fast, the fleet covers a meaningful range of real-world emergency and planned outage scenarios. Here is what is available and how to think about which unit fits your situation.

When a rental boiler makes sense

There are three scenarios where a rental boiler is the right answer. The first is an unplanned failure, where a boiler has gone down unexpectedly and the facility cannot wait weeks for parts or a replacement unit to arrive. The second is a planned outage, where a facility is taking its primary boiler offline for service, retubing, or inspection and needs to maintain operations during the maintenance window. The third is a temporary load, where a construction project, a seasonal spike, or a process change creates a demand that exceeds current capacity for a defined period.

In all three cases, the rental approach solves the same fundamental problem: the facility needs heat, steam, or hot water now, and the permanent solution is not available yet.

“The question is not whether you need a solution. It is how fast you can get one on line. GP Energy’s rental fleet is maintained and ready to deploy across Eastern PA, Southern NJ, and Delaware.”

The GP Energy rental fleet

The fleet spans a range of capacities, pressures, and fuel configurations. Most units can operate on natural gas or No. 2 fuel oil, which is a meaningful advantage when a site has fuel supply constraints or when utility gas pressure is interrupted during an emergency.

Kewanee L3S-50 · 50 HP
15 PSI steam · Dual fuel natural gas / No. 2 fuel oil · Steam boiler

Kewanee M115 · 34 HP
30 lb hot water or 15 PSI steam · Dual fuel natural gas / No. 2 fuel oil

Burnham 4FL-209-45-G · 52 HP
15 PSI steam or hot water · Dual fuel natural gas / No. 2 fuel oil

Bryan CL210-S-150 · 50 HP
150 PSI steam · Natural gas atmospheric · High-pressure steam applications

Burnham · 250 HP
150 PSI steam · Dual fuel natural gas / No. 2 fuel oil · Enclosed in sea container for outdoor deployment

Sellers · 350 HP
150 PSI steam or hot water · Natural gas / propane · Outdoor construction, no shelter required

Sellers · 125 HP
150 PSI steam or hot water · Natural gas / propane · Outdoor construction, no shelter required

High-pressure steam deserves specific attention

Most commercial heating applications operate at low pressure, typically 15 PSI or below. But industrial processes, laundry facilities, food production, sterilization applications, and certain institutional buildings require high-pressure steam in the 100 to 150 PSI range. That is a different category of equipment, and not every rental fleet carries it.

The GP Energy fleet includes three units capable of 150 PSI steam output: the Bryan CL210-S-150, the 250 HP Burnham in the sea container, and the 350 HP Sellers. For an industrial facility that needs high-pressure steam restored quickly, having those units available in this region matters. Most rental boiler providers operate at low pressure only.

Heat exchanger rental for hot water applications

Not every thermal emergency requires a boiler. In buildings where steam is available but domestic hot water or hydronic heating needs to be restored, a rental heat exchanger can be the faster and simpler answer. GP Energy maintains two rental heat exchangers for exactly these situations.

Rental heat exchangers

HX-250 Steam to Water Heat Exchanger
Capable of providing 717 GPM of hot water at a 30-degree delta T using 125 PSI steam. Includes one system circulator pump with a 30 HP motor and VFD (208/230/460V), a 30 PSI steam pressure regulator, two steam control valves, a steam trap, and a flash tank. Complete packaged system ready to deploy.

HX-72 Heat Exchanger (Thermal Solutions H2O Max Model H72)
72-gallon tank volume. Capable of producing 828 GPH of 120°F domestic hot water with a 55 GPM house circulator pump. Boiler water supply 180°F, return 160°F, cold water inlet 40°F. MAWP 150 PSI. For domestic hot water restoration where the boiler is intact but the water heating system has failed.

Outdoor units change what is possible

Two units in the fleet deserve specific mention for facilities where getting equipment inside the mechanical room is not possible during an emergency. The 250 HP Burnham is housed in a sea container, meaning it can be deployed to a site, connected to existing piping, and operated without any shelter or enclosure. The 350 HP Sellers and the 125 HP Sellers are outdoor-construction units built for the same purpose. If the mechanical room is inaccessible, flooded, or too small to accommodate the rental unit, outdoor deployment is not a workaround. It is the plan.

GP Energy Products has operated the Proactive Boiler Response Team since the company’s early years. The rental fleet is maintained, tested, and ready to deploy across Eastern Pennsylvania, Southern New Jersey, and Delaware. If you manage a facility with a boiler that is aging, overloaded, or overdue for inspection, the time to know what is available in the rental fleet is before you need it, not after.

Need a rental boiler or heat exchanger?

GP Energy Products maintains a rental fleet spanning 34 to 350 HP, 15 to 150 PSI, for emergency deployment and planned outage coverage across Eastern PA, Southern NJ, and Delaware. Electric, hot water, and steam units available. Call before the emergency or call during one. We will respond either way.
