Evaporative towers

Evaporative towers, also called cooling towers, are thermal machines employed for the cooling of process water thanks to the direct thermal transfer with air and the physical process of evaporation.
The contact of the water with cooler air causes the evaporation of part of the water, which is achieved absorbing and thus dissipating heat.

The term free flow is referred to a special kind of plates employed in heat exchangers, with typically large and wide passages and no contact points.
The peculiar configuration of the plates lead to a plates pack in the exchanger that allows the free flow of dirty fluids rich in suspended particles through the plates without clogging the exchanger.


Glycol water

Glycol water is water with the addition on mono ethylene glycol, an anti-freeze fluid essential in applications with heat exchangers, cooling systems and free coolers in order to ensure frost-protection of the plant during the coldest winter season.
Pipings of cooling plants exposed to the low winter temperatures are in-deed facing the risk of severe and costly damages and bursts, due to the expansion rate of water when freezing within the hydraulic circuits.


Heat pumps

Heat pumps are devices that employ a thermodynamic cycle using a heat exchanger in function of evaporator, a compressor and another heat ex-changers as a condenser.
Depending on the seasonal need, the thermal cycle can be reversed in order to produce heat or cold, and thus heating or conditioning, absorbing thermal energy from the outside or from the inside based on the need.

Heat recovery

Cooling applications within industrial processes using heat exchangers often allow to study and implement heat recovery solutions, increasing the overall energy efficiency.
The heat generated by the production process which is dissipated to ensure the proper operating conditions of the plant can indeed be recovered and reused for heating tasks required in other steps of the production process or to obtain warm water for sanitary use.

Heat exchanger

A passive device employed for heating and cooling tasks using the physical principle of thermal transfer between two fluids having different temperature levels.
There are several typologies of heat exchangers, plate heat exchangers, shell and tube, blocks and finned battery exchangers, each one offering efficiency levels to be evaluated depending on the kind of thermal application.

Immersion Exchangers

Immersion exchangers are a kind of dimple jacket exchangers where the cooling or heating effect is achieved through direct immersion in a thermal transfer fluid.
This kind of heat exchanger also allows to leverage geothermal energy, for example with direct immersion of the exchanger in seawater on lake water.

No plume towers

Evaporative towers have a characteristic white plume coming out of the tower, clearly indicating their evaporative cooling process: this is in fact water vapor, resulting from the evaporation process.
In case the plume can be annoying, or even dangerous for example com-promising visibility in the nearby of an airport, it is possible to have no plume towers with retro-fit systems to tear it down. Wet-dry systems can also be employed to eliminate the problem at the origin.
