Applications

Successful and effective processes start with good design and the right equipment for the task, combined with minimal environmental impact.

Our expertise in designing, installing, commissioning and servicing our bespoke air and gas handling systems helps you achieve these important objectives on site.

We are embedded in your team of engineers as your trusted advisor from the start of your project through to handover and beyond.

Aeration plays an essential role in the wastewater treatment process, delivering air to enhance aerobic biodegradation of organic materials. A well-designed aeration system directly impacts the efficiency of the wastewater treatment process, reducing the length of time the process takes, while increasing energy efficiency and cutting costs.

In a typical wastewater treatment plant, the process of air production represents over half of the total energy used. Our high-speed turbo blowers improve efficiency in wastewater treatment plants, saving up to 35% of energy consumption. Reduced running costs coupled with virtually maintenance-free operation have a substantial impact on the environment and total cost of ownership.

Uses:

Northey’s high-speed turbo blowers are used in a variety of applications, including:

  • Dissolved air flotation (DAF) treatment
  • Induced gas flotation (IGF) systems
  • Activated sludge treatment
  • Removal of suspended solids
  • Waste particle separation

• Integrated circuit cleaning

Our aeration equipment can be designed and adapted to accommodate most applications across a wide range of sectors. To find out more, please contact our specialist team.

Our side channel blowers and fans create continuous sheets of precisely controlled high-velocity air suitable for any application requiring controlled air flow, from moving goods on production lines to creating controlled air barriers to prevent moisture and debris entering your operation.

Uses:

  • Product drying – including bottles, cans, crates, cartons, jars, components, rubber or plastic extrusions, rods, tubes. automotive, printed circuit boards, packaged products
  • Cooling – including castings, extrusions (rubber or plastic), steel strip, light bulbs, ingots, metal extrusions
  • Product coating
  • Cleaning
  • Removal of surface moisture and/or debris

Whether you are mixing liquids, solids or gases, blending can be one of the most critical and challenging phases of the manufacturing process, and inefficient blending practices can lead to higher energy use and operating costs.

Northey’s Hook and Claw and Side Channel Blowers are built to help you optimise this critical process due to their dry and oil‑free design, which ensures the blending air is not contaminated with lubricating oil. They can be used across a wide range of industries.

Uses:

  • Flocculation
  • Polymer injection into sludge stream
  • Blending of chemicals
  • In-line pH control
  • Wastewater neutralization
  • Liquid-liquid dispersions
  • Fuel/oil blending
  • Catalyst additions
  • Dye blending
  • Dispersion of solids into liquid streams


Having power in the form of compressed air provides end-users with much more control over usage and air quality. Around 90% of all manufacturing companies use compressed air in their production and plant processes in some form or other and it is such an essential element in processing that we call it ‘the third utility’.

Northey’s two-stage high-speed turbo compressors with magnetic bearings provide high volumes of dry, oil-free compressed air at pressures up to 10 bar(g). These systems require negligible maintenance and offer proven energy savings of 35% over conventional piston compressors. These savings coupled with low maintenance costs are of tremendous benefit to high users of compressed air such as breweries, food production lines and the motor industry.

Uses

  • Washing and drying
  • Operating air tools on production lines
  • Moving product on conveyor systems
  • Packaging lines
  • Paint-spraying
  • Spray-drying
  • Coatings and additives
  • Cutting and welding equipment
  • Ejecting pieces from production moulds
  • Adjusting roller and feed machinery
  • Blowing plastic bottles
  • Efficiently performing basic tasks such as driving screws and turning nuts
  • Increasing production efficiency with air cylinders that power positioners, clamps, air chucks, and air knives
  • Finishing and packaging
  • Sandblasting and finishing metal
  • Operating automated machinery

Removal of phosphate from effluent is an essential part of wastewater treatment for utilities to comply with environmental legislation. The continuous dosing of ferric sulphate at water treatment works requires the application of reliable, high performance systems.

Northey has developed a suite of mixing system packages to be used in association with chemical dosing and water quality management systems. They can be mounted on skids or installed in kiosks. Applicable to both municipal and industrial water & wastewater treatment applications, they are ready for installation into existing structures.

Northey was a pioneer in ferric dosing and our skids are in regular use across the water utility sector.

Uses:

  • Phosphorous removal from wastewater
  • pH control for clean water and wastewater
  • Clean-in-place systems for industrial processing applications
  • Chemical precipitation in drinking water
  • Descaling in industrial applications

Northey specialises in the design and manufacture of compressors and vacuum pumps for handling a wide variety of gases.

The gas is compressed between precision machined rotors so there is no metal-to-metal contact and no need for lubrication, meaning no risk of gas contamination.

Uses

Our application experience is extensive and includes:

  • Boosting combined heat and power (CHP) engines
  • Gas mixing for anaerobic digesters
  • Biogas processing at solid waste landfill sites
  • Gas and emissions reclaim and recovery at petrochemical facilities
  • Industrial gas production and distribution – including argon, oxygen and hydrogen
  • Extraction of reactive gases in plastic foam production
  • Extraction of production gases in electronic component production

Natural gas flaring not only represents a lost economic opportunity but is also a major source of greenhouse gas emissions. Flaring of natural gas releases over 400 million metric tonnes of carbon dioxide equivalent (CO2e) emissions globally every year.

Vent and vapour gases often contain harmful volatile organic compounds (VOCs), so it is vital to ensure recovery systems are safe and reliable – with minimal maintenance requirements. Efficient use of natural gas resources not only helps meet global energy demands but also mitigates climate impact and reduces air pollution.

Remote sites, such as offshore platforms, are often unmanned and require low maintenance and long mean time between failures (MTBF) of equipment is essential.

Uses:

  • Petroleum refineries
  • Gas treatment and natural gas liquids (NGL) plants
  • Chemical production
  • Storage tank vent recovery
  • Floating production storage and offloading (FPSO) vessels
  • Purging and internal inspection of gas pipelines [CHECK]
