pressure washers for oil & gas industry

Pressure Washers for Hazardous Environments

These hazardous areas are common obstacles many businesses need to work around. To ensure the safety of their employees, facilities, and assets, companies must take special precautions to ensure all their equipment is compatible with these environments, and the use of industrial pressure washers is no exception.

The equipment we offer for hazardous areas can be powered by either:

  • Diesel engine
  • Electric motor
  • Air motor

 

Advantages

The main focus of these types of products is safety, but when comparing industrial pressure washing systems for hazardous environments to standard equipment, the biggest difference is the electrical components. All of the components (power supply cable, connection to the motor starter, connection from the motor starter to the motor, heater, and controls) meet the requirements of the specific hazard which makes these components, larger, heavier, and more complex.

 

Equipment Sizes

For all our equipment systems, there is no size limitation. We have provided Custom Equipment Solutions that are as small as 1.0 hp to as much as 150 hp, from 100 psi to 15,000 psi, flow rates of less than 1 GPM to 30 GPM. The configurations are almost limitless.

 

Available Materials

For these systems, where possible, non-sparking materials are used. All components need to be certified to meet the area classification requirements. The term "Explosion Proof" generally refers to equipment that is designed to operate safely in an area where the potential for fire or explosion exists due to flammable gases or vapors, flammable liquids, combustible dust, or ignitable fibers or flyings.


Standards & Requirements

There are standards, requirements, and certifications available for just about every classification of a hazardous environment. The important thing is to make sure that every component is certified for use or operation for the specified hazard.

Our designs use components that are listed or certified by recognized authorities (like UL, CSA, IEC, ATEX, CE, ETL, ITL, etc.) for use in a specific area classification that is equal to or greater than the classification of the area where it is to be used. These components are installed in accordance with the specified standards (NEC, NEMA, IEC, API, DNV, ABS, etc.).

In some cases, the entire pressure washer is certified.

 

Niagara Industrial Pressure Washers

The Niagara Product Line includes "explosion-proof" pressure washers with either air motor or electric motor drives with steam cleaners and hot water pressure washer versions using electric heaters and steam heat exchangers.

There are options available for NEC, IEC, ATEX (or any other) complaint or offshore (API, ABS, DNV, etc.) compliant equipment.

Should the standard configuration not meet the application requirements, the Niagara design team can provide custom equipment to your specifications.

Hazardous Environments

Hazardous work environments These hazardous areas are common obstacles many businesses need to work around. To ensure the safety of their employees, facilities, and assets, companies must take special precautions to ensure all of their equipment is compatible with these environments, and the use of industrial pressure washers is no exception.

These hazardous areas are common in the Petroleum Industry and include facilities such as:

  • Drilling rigs
  • Refineries
  • Pipelines
  • Chemical plants
  • Tankers (rail, truck, and ship)
  • Fuel stations (both commercial stations and local service stations)
  • Dry cleaners
  • Spray applications using flammable & combustible materials
  • Dipping & coating processes
  • Manufactures of organic coatings
  • Solvent extraction plants
  • LPG storage & handling sites
  • Pharmaceutical plants
  • Grain elevators

 

Hazardous Area Classes

Hazardous areas are classified in accordance with the National Fire Protection Association (NFPA), the American Petroleum Institute (API), and the Instrument Society of America (ISA). In these cases, the primary hazards are ignitable substances (like dust around grain elevators and pharmaceutical manufacturing, gasses or liquids such as in the oil and gas industries) that either are or could be present in a specified area. The classes and divisions refer to the specific hazard and likelihood of them being present.

 

Classifications Overview

Class I (gases) locations where flammable or ignitable gases are in the air in sufficient quantities to produce explosive or ignitable mixtures.

Groups A, B, C & D further classify gases according to explosive pressure and therefore the most difficult to contain with Group A being the most difficult.

  • Division I an area where the hazard can exist under normal operating conditions.
  • Division II an area where the materials are handled but under normal conditions are contained, hazardous materials are present only in case of equipment failure or accident.

T1-6 temperature rating, the "T" rating of heat-producing equipment must not exceed the ignition temperature of the flammable material present.

 

Class II (dust) area where the presence of combustible dust presents a fire or explosion hazard.

Groups E, F & G classified by electrical conductivity and ignition temperature but generally grouped as metallic, coal, or grain.

  • Division I an area where the hazard can exist under normal operating conditions.
  • Division II an area where materials are present only in case of equipment failure or accident.

T1-6 same as in Class I.

 

Class III (fibers) atmospheres containing easily ignitable fibers such as rayon, cotton, flax, jute, hemp, and other similar fibers.

  • Division I an area where these fibers are manufactured, handled or used.
  • Division II an area where these fibers are stored or handled.

 

Additional Regulations and Classifications

The NFPA is the sponsor of the National Electrical Code (NEC) which is the national standard for electrical equipment and electrical installations. These requirements generally state that approved (UL, CSA, etc.) components are to be installed in accordance with NEC practices designated for the specific classified area and environment.

The National Electrical Manufacturer's Association (NEMA) publishes a classification system for electrical enclosures. Those types typically used in the pressure washer/steam cleaner industry are as follows:

Type 1 for indoor use, provides protection against limited amounts of falling dirt.

Type 3R for outdoor use provides protection against falling rain.

Type 4 for indoor or outdoor use providing protection against windblown dust and rain, splashing water, and hose-directed water.

Type 4X meets type 4 requirements and protects against corrosion.

Type 7 for indoor use in locations classified as Class I, Groups A, B, C, and D.

Type 9 for indoor use in locations classified as Class II, Groups E, F, and G.

Also, certain combinations are available such as NEMA 7 and 4 or NEMA 7&9/4X, which are common in the petroleum industry.

Outside of the U.S., there are other governing bodies with their classifications such as IEC (International Electrotechnical Commission).
