Bootstrap Gas Booster Packages (Nitrogen Gas Booster Systems)

MAXPRO Technologies Inc. designs, engineers, and builds a wide variety of high-quality “Bootstrap” Gas Booster Packages to boost nitrogen pressure. Here we will discuss what MAXPRO Technologies Bootstrap Gas Booster Packages are and how they work along with their typical applications and benefits.

What Is a Bootstrap Gas Booster Package?

Bootstrap Gas Booster Packages are capable of boosting gas pressures over a wide range from just a few hundred psi all the way up to 36,000 psi. Our bootstrap systems differ from our gas racks in that all of the components are mounted on the booster itself as opposed to our frame mount designs. Bootstraps are ideal for integration into applications where space is limited and when portability and economy are key considerations.

Since we can design and build our Bootstrap Packages around any of our 32 models of air-driven Maximator gas boosters, we are able to tailor them to meet your individual gas boosting needs.

How Does a Bootstrap Gas Booster System Work?

The term “bootstrap” comes from the fact that there isn’t any frame. All components load onto the booster, resulting in systems that are considerably smaller and more portable. They are also easy to integrate into existing machinery.

Along with the gas booster itself, Bootstrap systems include essential modular components:

  • Air Control Package – Drive air regulator and filter, air pressure gauge, shut-off ball valve, and fittings
  • Inlet Plumbing – Connects the gas source to the booster inlet ports
  • Outlet Plumbing – Collects boosted pressure gas from the outlet ports and provides a common connection to the customer’s application system.

Running a bootstrap gas booster system involves several key steps. Initially, the air drive is turned off using the included air shut-off ball valve. Next, the air regulator is adjusted so drive air pressure is correct to achieve the desired gas outlet pressure according to the booster’s pressure ratio. Once the air regulator is set, the shut-off ball valve can be slowly opened to start the booster. Once the booster is running, adjustable air pressure pilot switches then control the system.

Air pilot switches used on bootstrap packages are available in either normally open (“NO”) or normally closed (“NC”) configurations. The “NO” pressure pilot switch is connected to the booster’s high-pressure circuit side and is set to shut off pilot air to the booster once the outlet pressure reaches the desired level. The “NC” pressure pilot switch is connected to the inlet gas circuit and will shut off pilot air to the booster once the gas supply pressure drops below a certain level. High-pressure circuit “NO” pilot switches are standard on all MAXPRO Technologies gas booster package systems. “NC” pressure pilot switches are not standard but can be quoted.

System Applications

Our Bootstrap Gas Booster Packages work with a wide variety of applications across a range of industries. Some of these specific applications include:

  • Pressure component leak testing
  • Gas-charging accumulators
  • Low-pressure gas recovery from supply bottles – this is particularly important where costly gases such as helium, high purity argon, neon, and others are used.
  • Gas-assist injection molding
  • Pressurizing gas cylinders and shock absorbers
  • Boosting gas pressures from vaporized liquids
  • Boosting gas pressure from oxygen and nitrogen generators

Air Amplifier System AS-DLA15-1-1G-PS

Our Air Amplifier System AS-DLA15-1-1G-PS utilizes a Maximator Model DLA15-1 Air Amplifier and offers an ideal solution for boosting compressed air to pressure ranges higher than most typical shop air systems.

This is an ideal system for amplifying compressed air from 100 psi to 1,000 psi. It is equipped with a single-acting, single-stage air booster and is entirely pneumatically driven, no electric power required. Highlighted benefits include:

-Compact design that saves space

-Easy installation

-Only requires a supply of compressed air that is equal to or greater than 100 psi

Built into the system is a pressure switch that can be adjusted and set to pressures ranging from 435 psi to 1,000 psi. The main advantage of the pressure switch is that it automatically shuts off the system once the required pressure is reached. It can also automatically restart the system as compressed air is withdrawn from the system. Once the system senses a 10 percent drop from the set pressure, the amplifier will restart and begin to cycle again, creating more compressed air to refill what has been extracted. Combined with a 1-gallon sample cylinder attached to the system, this amplifier is ideal for small projects that require a few liters of compressed air to be ready on tap.

Equipment Considerations for Hydrogen Applications

Due to the inherent dangers of working with pressurized hydrogen, it is important to utilize high-pressure equipment that is reliable even in hazardous conditions. An understanding of the specific considerations for these types of applications helps ensure workplace safety and compliance with industry standards.

Importance of Using the Right High-Pressure Equipment

When compared to other types of fuel, hydrogen has a very wide flammability range. It is therefore vital that high-pressure equipment used in hydrogen applications does not have any weak points, as hydrogen may press against these points to create cracks or leakage. If the equipment cannot safely contain hydrogen, there are several hazards to be cognizant of.

When pressurized hydrogen causes a crack in the piping system, it may lead to explosions. This is particularly dangerous because hydrogen requires such low amounts of energy to ignite. Hydrogen flames are difficult to see in daylight and do not produce smoke, making them challenging to identify without getting hazardously close.

In addition to the risks surrounding hydrogen explosions and flames, other hazards to note include:

  • Hydrogen embrittlement. When hydrogen causes a material to lose ductility and become brittle.
  • Hydrogen permeation. A phenomenon wherein hydrogen ions penetrate thin diaphragms, leading to inaccurate measurements.
  • Hydrogen asphyxiation. A significant risk when hydrogen accumulates during a leak.


Factors to Consider When Selecting High-Pressure Equipment

When selecting the appropriate high-pressure valves, fittings, and tubing, there are many factors to consider:


High Pressure Valves

High pressure hydrogen valves must meet strict industry standards to ensure high performance even in harsh environments. Factors to consider when choosing a hydrogen gas valve include:

  • Temperature range. The valve must be able to operate well at a wide range of temperatures.
  • Regulating stem design. A regulating stem controls the flow of gas.
  • Seat material. Metal seats create a tighter shut-off, resulting in improved equipment longevity.
  • Valve body patterns. There is a range of patterns available depending on the needs of the application.
  • Sizes and ratings. Choosing the appropriate size ensures the valve will perform well under the required pressure.


High Pressure Fittings

Factors to consider when choosing high pressure fittings include:

  • Types of fittings. There are a range of fitting types to choose from, including adapters, couplings, and elbows.
  • Sizes and ratings. Depending on the size, fittings may have a pressure rating of standard, medium, high, or ultra high.
  • Quality control and industry standards. High pressure fittings should meet quality control standards such as those set by ASME.


High Pressure Tubing

When choosing high pressure tubing, it is important to consider both the diameter size and the pressure ratings. Tubing with a smaller diameter will generally withstand higher pressures than tubing with a larger diameter.

When paired with the proper equipment, hydrogen has a vast array of applications, including:

  • Fuel cells
  • Power plant generator cooling
  • Chemical
  • Petroleum refining
  • Oil and gas
  • Hydrogenation of unsaturated fatty acids in vegetable oils
  • Hydrogen fueling stations
  • Glass manufacturing
  • Aerospace applications
  • Welding, annealing, and heat-treating metals
  • Pharmaceuticals
  • Fertilizer and ammonia production
  • Waterjet
  • High pressure food processing
  • Semiconductor manufacturing

How to Repair Spool Valves

Maximator® dry air spools (DAS) can be used for liquid pumps, gas boosters, and air amplifiers. They are suitable for dry air, nitrogen, and other severe operating conditions (e.g., air dew point below 0° F and ambient temperature below 0° F). The following article covers how to repair and lubricate the spool valve.

Tools Needed:

  • Spool tool remover – Sold by Maxpro
  • Hammer or mallet
  • Pliers
  • Repair kit- Includes O-rings and a snap ring
  • Grease – We recommend Kluber Lube, Polylub GA 352 P High Temperature Grease. This grease has good long term adhesion and water resistance.

Overview of the Spool Valve Repair & Lubrication Process

  1. Loosen four cap screws that hold the spool housing to the end cap to release any air trapped in the spool valve.
  2. Remove the snap ring from the spool valve housing.
  3. With a long screw driver or wooden dowel, from the ½” FNPT side of the housing, push out the spool plug and spool from the housing.
  4. Clean the spool and bore of the housing sleeve. Check the O-rings for wear and the spool sleeve for scratches. Replace if necessary.
  5. Put a light coat of grease on the O-rings and in the bore of the spool sleeve.
  6. Insert the spool into the spool sleeve, small side first, gently moving the spool from side to side with very little pressure on the end of the spool. DO NOT FORCE. The O-rings fit loosely on the spool and can be cut if they are forced in.
  7. Install the spool plug and snap ring, then tighten the four cap screws that hold the housing to the end cap.

Product Spotlight: Maxpro’s High Pressure Relief Valves

Pressure relief valves are intended to protect system components from over pressurization. The pressure relief valve is often set at 10% over maximum system operating pressure to allow the system to operate up to the maximum working pressure rating. The maximum allowable working pressure for the system is based on the lowest rated system component. The size must be chosen to allow the rate of relief flow to equal or exceed the potential various sources of over pressurization. Materials of construction must be chosen to be compatible with the fluid or gas that will be encountered. Poor material choices could lead to faulty operation of the relief valve and failure to relieve overpressure as intended.

Features of MAXPRO®’s High Pressure Relief Valves

High Pressure Relief Valves

Proportional high pressure relief valves from MAXPRO® are designed with simplicity in mind. The goal is to support long term reliability, performance, and serviceability, while providing the safety relief valve function. The relieving function is accomplished by an adjustable spring force acting upon a stem that presents two unequal areas for inlet pressure to act upon, causing stem lift off the seat. The higher the spring force, the higher the relieving pressure. With the proportional relief valve design, higher system pressure causes higher stem lift, resulting in higher relieving flow. This “unbalanced stem” design also provides for smoother operation over those that simply lift from the stem area under the seat and minimizes the reseating pressure window as well as hysteresis of the set pressure. These valves are not poppet style relief valves. At a preset pressure, poppet style relief valves “pop” full open for maximum flow, and then snap closed at some reseating pressure. Poppet style valves tend to be more complex to achieve the pop-open action.

MAXPRO® offers proportional relief valves with four minimum/maximum set pressures to support most applications. Choose from:

Note: The sensing pressure enters the side port and exits the bottom port. MT3RV and MT10RV have two standard side ports. The second port can be for a tee for a gauge or vent line, or the extra side port can be plugged if preferred. MT25RV and MT66RV have one sensing port.

Choosing the Right High Pressure Valve

MAXIMATOR high pressure valves are designed to safely operate at pressures of 15,500 psi for a 1-½” medium pressure valve up to 101,000 psi for an Ultra-High Pressure Valve. High pressure valves are used to regulate flow in various fluid handling operations across a wide range of industries, including aerospace, automotive, military, and mining industries. Selecting the best, high pressure valve for your application is crucial.

There are many factors to consider when choosing a high pressure valve. Below, we highlight some key factors to consider when choosing the right high pressure valve for your application.

Factors to Consider When Evaluating Your High Pressure Valve Needs

Important factors to consider when evaluating whether a particular high pressure valve is right for your fluid handling application include:

  • Process medium: The valve should be able to handle the process medium, whether it is in gas, liquid, or steam form, inert, abrasive, or corrosive, and hot or cold.
  • Pressure rating: It should be rated to handle the range of pressures expected in operation. Consider upstream and downstream pressure for the maximum, normal, and minimum flow rates.
  • Temperature: The valve should be rated to handle process medium temperatures.
  • Flow rate: A high pressure valve should be properly sized to ensure it has the proper flow rate capacity.
  • Connection type and size: It should have a connection type and size that fits the inlet/outlet piping.
  • Valve style: Do you need a manual valve or an air actuated valve? If air operated, should the valve be air-to-open (normally closed) or air-to-close (normally open)?
  • Construction material: A high pressure valve should be constructed of material that can withstand the process medium and operating conditions (temperature, pressure, flow, etc.). For example, stainless steel is suitable for fluid handling operations involving corrosive materials.
  • Application: It should be appropriate for implementation in the system.
