Wastewater Treatment Ventilation: Polypropylene vs. Stainless Steel and GRP

Wastewater treatment plants face a number of challenges in terms of ensuring safe and effective ventilation. The chemicals used during the wastewater treatment process pass through metering equipment in a dosing system. In the system, the solution is at its strongest and the chemicals and their gases are often corrosive and can be flammable. Such chemicals and gases include methane, ammonia, phosphorous, pesticides and carbon dioxide. Consequently, wastewater treatment plants are, by their nature, one of the harshest engineering environments. ...


Lions Feel the Benefit of Quiet, Efficient Roof Fans

Avoiding Corrosion in HVAC & Protecting Employee Health

When installing a HVAC system, the main aim is usually to heat or cool the environment for employee comfort. Often underestimated is the impact that HVAC systems can have on employee health. Corrosion, caused by the presence of chemicals, is one of the biggest threats to HVAC systems and indicates an unsafe environment for employees. Corrosion damage and its consequences in HVAC systems are discussed below. What is Corrosion Damage? Corrosion mainly occurs in metals when they react with their environments; their refined form turns into stable...


Renewable Energy: Fans for Wind Turbines

The UK's offshore wind power capacity is set to nearly double by 2030, as a result of a new government initiative. Offshore wind has become an increasingly affordable source of clean energy due to plummeting costs. This, coupled with an increasing environmental awareness in consumers, is reinvigorating the focus on wind as a source of inexpensive, renewable energy. Wind turbines require fans to ventilate and cool several different areas to maintain and preserve the functioning of its equipment. These areas include the nacelle, generator, tra...

Space Saving Enclosure Ventilation: Roof Exhaust Units

An ever increasing problem with ventilating a control cabinet is having the space to fit a filter fan to the front of a cabinet. The density of equipment fitted often allows little space for the filter fan to fit to the door or have sufficient room within which to effectively cool the equipment. It may also be the case that the sides of the control panel or enclosure are surrounded by other panels, walls, or any other obstacles. The solution is straightforward and involves fitting a roof exhaust unit. Roof exhaust fans can be an effective al...

Process Cooling in Factories

Process cooling in industry is an important part of manufacturing. The cooling of products and removal of large amounts of heat throughout the year increases the efficiency of production processes and operations of equipment ranging from food processing, packaging, plastic injection molding to medical imaging equipment. With continuous innovation, there is often a reduced requirement for mechanical cooling. Processes are often cooled using just air. This has a number of benefits including a reduced operating cost. Airflow helps accelerate...
