Waste Water - There are many applications for low pressure air in the waste water market, which range from simple aeration to air scour and filter backwashing. Most requirements are suited to our Side Channel and Diaphragm ranges as they are oil-free and offer many operational advantages over other makes and designs on the market. Most noticeable, is the saving on power and cost, as well as the ability to custom build the blowers to WIMES as required. As a specialist supplier in this market, we have also developed our blower range for frequency control, giving optimum operating efficiency. In addition, customers can specify their preferred motor manufacturer, which, unlike many other blower designs, can often be fitted in a direct coupled arrangement, eliminating the need for a belt driven system.
Sewage Treatment - Northey has been recognised for more than 40 years as the market leader in the manufacture and supply of sludge mixing compressors for the water industry. Our proven 'Hook & Claw' principle has been adopted as the preferred technology by many of the leading water authorities, due to its many operational advantages. In the application of sludge mixing, the Northey 'Hook & Claw' re-circulates and compresses the biogas without any oil contamination or contact between rotating parts. This ensures there is no possibility of oil carry over into the process as well as other problems associated with oil in the system - leakage through moisture drains and the blocking of ancillaries such as flame arresters. Many sites have reported excellent life costs and minimal maintenance, which has become more critical with the reduction in manned sites. Northey also offers rotary vane compressors for gas mixing, where capital cost is of primary concern.
Northey has also supplied many air blowers for sewage treatment, especially on small population plant where compact size, noise, efficiency, capital cost and running costs are all of equal importance. Developments in the area of variable speed have shown Northey compressors to be extremely reliable and capable of greater turndown ranges than many of its rivals.
Gas
- Biogas is one of the most difficult gasses to handle due to its moisture
content and corrosive nature. Northey compressors and blowers are proven to
work successfully on the most demanding applications such as, biogas mixing
systems and gas boosting for power generation. All of our packages and ancillary
items are designed to withstand the long term effects of the gas, both internally
and externally. As a result, many of our packages remain in operation well
beyond the anticipated life of the plant.
Power Generation - The effective handling of gas is critical in the
area of power generation. Not only does the compressor/booster need to generate
the required pressure and flow for optimum system operation, but it needs
to work with the highest reliability. From our extensive range of booster
sets and compressors, we can select to meet the
exact needs of the client.
