Cooling Towers

Cooling Towers – Aqua Cooling can design, supply and install a range of cooling towers, whether you require a one-off unit or a multi-cell solution. The size tower and level of thermal performance are unlimited and we can design completely bespoke options. Our factory assembled cooling tower range includes both open and closed design towers and crossflow, counterflow, forced draft and induced draft models.

Help With Product Selection

We’re aware that sometimes the cooling tower sector can appear quite daunting to clients and prospective customers. Whilst there are so many different types and configurations possible, in the main the type of cooling tower needed is dictated by the design criteria and operating conditions required for the specific application. Sizes and models of tower do vary considerably but our engineers are on hand to help you fully with product selection and system design. We’ll ensure you have the most efficient and cost-effective option for your application or process and we’ll help you every step of the way, from initial enquiry right through to delivery and installation.

Design Options

Our range includes towers manufactured in a variety of base materials, including galvanised steel, stainless steel 304 or 316 and GRP. Our glass reinforced plastic – or GRP – models are non-corrosive, unaffected by water treatment chemicals which improves lifespan but also making them ideal for coastal locations and/or marine applications.

Models include low profile towers, which are often suited to inner city applications and if noise pollution is an issue we can add silencers and centrifugal fans to give a low noise solution. We also offer closed circuit towers with cooling coils which give additional water quality advantages. Technical excellence and robust engineering play a huge part in the design of our cooling tower units. We offer a product that is highly reliable, yet cost effective, with ongoing maintenance kept to a minimum, resulting in a unit that’s built to last but offered at a competitive price point.

Types Of Cooling Tower

Below is a brief overview to the main types of cooling towers available:

> Crossflow – the air and water flow effectively cross each other, the air flows horizontally and the water drops vertically through the fill media.

> Counterflow – air is pushed up vertically, counter to the water which is flowing vertically. This means it’s not possible to take advantage of the gravity flow so pressurised spray systems are used to spray the water onto the fill media.

> Forced draft – air is pushed, or forced, by blowers located at the base of the air inlet face.

> Induced draft – fans are used to pull the air up and through the fill media. The fans are commonly sited on the top of the cooling tower unit.

How Do Cooling Towers Work?

Fundamentally, cooling towers are an organic heat exchanger. Warm or hot water from a process is cooled by passing it through the tower and then back out into the process. A cooling tower enables the water to meet the air so that some of the water evaporates, lowering the overall water temperature.

Water is pumped, usually from the basin of the tower or a sump tank below the cooling tower, through pipework to the process. This is then returned to the cooling tower, where it is either sprayed by nozzles or returns to a tank at the top of the tower – to gravity drain onto fill media to maximise air to water contact. The water flows over the fill media or packing and meets air, which is then either pulled or pushed through by fans. This is evaporative cooling.

Open vs Closed Cooling Towers

Closed circuit cooling towers and open circuit cooling towers both cool the process water but just go about it in different ways.

With an open circuit cooling tower, the process water comes into direct contact with the external air stream, with the hot/warm water being distributed over a specialised fill or packing. This gives a platform for the evaporative cooling to take place as the air and water interface. The water is cooled as it passed through the packing and then collected in a basin below. The air now heated and moisture laden, leaves the fill and is discharged into the atmosphere. The issue here is that any contaminate within the air is passed into the cooling water. Also, as the water is treated for biocides and softened, these can build up in the system over time.

A closed-circuit tower has an internal or external heat exchanger and the process water is separated from the ambient air, therefore maintaining its quality and cleanliness at all times. The disadvantage is that the heat exchanger adds to the size of the cooling tower and therefore price is significantly higher.
