Thermal management system

Overview

Our solution

Our new thermal offer includes a large range of solutions, suitable for all situations,

from installing a ventilation system to exchangers or even a cooling unit.

Do not hesitate to contact us to find out the best thermal solution for your installation.

Risks associated with the lack

of thermal control

Random breakdowns and production halts result

in heavy losses

Thermal control of enclosures extends the service life of the components and

reduces their breakdown rate.

Sudden production halt

The appearance of hot spots increases the breakdown rate and endangers the

production process.

Example

Electronic equipment

Most electronic industrial control systems are equipped with axial fans for their own

thermal control. A failure of the fan can lead to a production halt.

Reduced service life of the fan is one consequence of the enclosure heating up.

Service life at 60°C (L10 at 20°C): 20000 h.

The service life of the equipment can drop from 50000 h to only 20000 h.

The internal temperature increases with a high degree of IP

In agressive atmospheres: dust, humidity, chemical agents, high temperatures, etc.,

the equipment is installed in industrial enclosures (IP54) in order to protect it from the

external environment. Nevertheless, it causes a reheating phenomenon which,

if left unchecked, will be responsible in the short term for a halt in the operation

of the components.

Example

Variable speed drives

A variable speed drive controlling a 45 kW (60 HP) motor is programmed to work at

temperatures ranging up to 50°C or 60°C.

The power dissipated by this variable speed drive inside the enclosure can reach 1360 W.

This contribution of heat inside the enclosure will cause the top temperature to rise

to 60°C and probably cause a halt in production.

Example

Batteries – Accumulators

Manufacturers recommend installing batteries in environments where the controlled

temperature is 15°C... 25°C.

Cold slows down the battery charging and discharging cycles. Heat increases the

evaporation of water in the electrolyte and speeds up the oxidation of the plates.

Using batteries at temperatures above the recommended value therefore reduces

their service life.

Reduction of the service life of the components

The service life of the components is considerably reduced if the temperature

and humidity in enclosures are not controlled. Repeated sudden variations speed

up the aging process.
