Revamping and Retrofitting of Cooling Systems

Your cooling technology back to initial efficiency. Or more

Refurbishment of large towers or targeted anti-corrosion interventions, change of internal components and retrofitting with subcooling: it is not always necessary to replace a cooler or an industrial chiller. It is often more useful to give it a plus.

Retrofitting a Cooling System with a Control Panel: Frequently Asked Questions and Expert Answers

Variable-speed fans, controlled by inverters, adjust the airflow according to the thermal load.

Some main advantages can be enumerated, related to reduced water use and optimized operation during different seasons and times of the day.

Modern evaporative coolers use automatic blowdown systems controlled by conductivity sensors, partial recovery of discharge water, and optimized make-up strategies. Adiabatic systems, on the other hand—with the proper use of sensors and PLC-based parameter settings—use water only during periods of maximum thermal load, reducing overall consumption compared to traditional cooling towers (though with some loss of efficiency). The adoption of recovery circuits also allows part of the water to be reused in any cooling system that relies on this resource.

During the design phase, the use of selection and configuration software makes it possible to compare different solutions—chillers, cooling towers, adiabatic coolers, or dry coolers—by simulating their seasonal performance and heat loads. These digital tools also estimate energy and water consumption and help optimize system sizing.

Requirement: equipment refurbishment and change of parts

When people talk about “revamping” cooling systems, they think of “refurbishing” large concrete cooling towers. In reality, any cooler and chiller can be brought back to full working order: for example with anti-corrosion measures (for coolers not designed in fibreglass) or by replacing its internal components.

It is also useful to think about how to simplify the maintenance of coolers and chillers in order to facilitate future work.

Plant Revamping in Cooling Technologies

Solution: MITA operations for every cooling technology

We work with our Group partner TORRAVAL Cooling for the revamping of field-mounted industrial towers. We work on the revamping of all cooling technologies with anti-corrosion repainting (for those coolers not designed in fibreglass) and offer a very wide set of spare parts: motor-fan units, louvers and water distribution systems for the towers.

If required, we can make future maintenance of your cooling system easier: for example, by adding side doors to make it easier to inspect the internal components.

Retrofitting

Often people do not think about how much the efficiency of a cooling technology can be increased by retrofitting: an inverter system with PLC added to an industrial cooler optimises consumption, controls and automates operations.

Another example, in commercial refrigeration, is the addition of sub-cooling technology in refrigeration: especially in the case of chillers using natural refrigerant gases. And the increase in performance is guaranteed.

A further requirement is to make cooling equipment quieter: motor-fan units with special configurations and sound-absorbing hoods can help.
