Cooling Tower Inspections

Wet Evaporative Cooling Towers should be inspected by competent Cooling Tower Engineers as failed or deteriorating components compromise performance and can lead to an unexpected catastrophic and costly failure.

TEC’s thorough Cooling Tower Inspections are carried out by experienced engineers who can determine L8 compliance and the integrity of the structure and internal components. Our inspections cover all types of cooling towers and include the following:

Cooling Tower Maintenance and Repairs

Wet cooling towers are designed to expend waste thermal energy to the ambient environment. Well maintained cooling towers conduct this process efficiently and safely whereas poorly maintained towers can become susceptible to the following problems:

Cooling Tower Cleaning and L8 Compliance (Legionella)

The Health & Safety Executive (HSE) states: “Where possible cleaning should be undertaken twice per year or more frequently where deemed necessary by the risk assessment. The Cooling Tower should also be cleaned after any shutdown in excess of a one month period (less for special applications), after completion of any major alteration to the tower or to the cooling system or where microbiological monitoring indicates a particular problem”.

Cleaning is designed to minimise the possibility of bacteria developing, in particular in areas where water vapour condensates but where chemically treated water does not come into direct contact, this can include drift eliminators, internal structural components, side walls and fan-stacks and even the packing itself where water distribution is uneven.

Cleaning also improves thermal performance as the easier it is for water to flow down against rising air the greater the heat transfer.

Cleaning should be carried out by Cooling Tower Specialists who understand the structure and composition of cooling towers. All cleaning performed by TEC conforms to ACoP L8 and involves using high volume low pressure washing with a feed of sodium hypochlorite. This technique avoids damaging the pack which is so often caused by inexperienced water treatment companies using too high a pressure.

All internal components and where necessary the external surfaces are thoroughly cleaned removing all signs of bacteria, sludge and scale. This is washed into the basin and then removed by hand or liquid ring vacuum suction tanker and on completion a Certificate of Cleaning in accordance with ACoP L8 is issued.

Cooling Tower Thermal Efficiency Surveys

Wet Cooling Towers are the most effective cooling systems, however, old or poorly maintained Cooling Towers can be inefficient and therefore consume a high level of energy in relation to the thermal energy expended.
The ratio of Electrical Energy used to Thermal Energy expended is the Coefficient of Performance (COP), a high COP indicates an efficient system whereas a low COP indicates inefficiency.

This example indicates that the cooling tower is inefficient by 38.8% and that in the same ambient conditions it would take 1 KW of Electrical Energy to lose 54.9 KW of Thermal Energy against an original design of 89.2KW.

This COP factor can then be used to calculate the cost of operating the tower and the energy wasted due to inefficiency.

Data from actual cooling tower in operation

Based upon the above data, energy costs can be derived, in this instance the cost of additional energy to achieve the required design performance amounted to £9,555. Couple this with unnecessary water loss and additional water treatment costs this medium sized tower was costing more than £16,000 per annum to operate than it should.

TEC provided a solution to improve efficiency and significantly reduce the cost of operation. We are committed to ensuring that Cooling Tower assets perform efficiently, effectively and economically and are able to provide advice on all aspects of operation.

Cooling Tower Parts and Spares for all Makes and Types

In addition to our site based activities TEC also supply components for cooling systems and our annual spend on cooling system components is in excess of £4 million with direct sales accounting for a little over £1 million including exports.

With a spend of over £4 million per annum covering every conceivable type of cooling system our established supply chain includes all the leading cooling system manufacturers including:

Balcke – Marley

Balcke - Duerr

Davenport

GEA

Hamon

Baltimore

Polacel

Film

Carter

Evapco

Mita

BAC

In addition, we have also built up a supply chain of parts manufacturers and are able to source the following directly from the manufacturers themselves;

Our extensive knowledge of cooling systems and library of drawings and our technical staff regularly identify systems and their components from the vaguest of descriptions.

We regularly supply and export components throughout Europe and the middle east complete with all the necessary export documentation and logistics. We also require our supply chain partners to maintain a stock of critical items for immediate delivery all of which combines to provide a first class support service for clients and our own field based engineers.
