Freeze 75 – and you have a temperature under control

temperature under controlA device operates OK until it reaches stable operating temperature … a typical situation in praxis usually caused by a faulty component or faulty (cold) joint. Localization of such a fault is easy only if we can cool down (locally) a given component or a given joint. It´s often possible to suppose a source of malfunction, but to be able to localize it exactly, we´d need to change temperature of only one component or only a small PCB area. Right for this purpose a well known spray Freeze 75, is designed, able to cool down (freeze) a given component very significantly – in laboratory testing down to -52°C.

And what about other possibilities of usage?
There are a lot of them. For example a local (preventive) cooling at soldering of temperature-sensitive components like temperature fuses or cooling of sensitive components near a soldered joint (for example soldering of a relatively bulky RF connector at a sensitive RF component, protection of plastic parts etc.) Another unusual help is at removing a rubber-like sticky substances from various places and textile. A typical example is removing of a chewing gum. Freeze 75 is also used in medicine, in machine engineering for shrinkage of small components etc.

How does the Freeze 75 function?
Again we´ll call for help a grammar school physics. When we go out of a swimming pool, we usually feel cold, even though there´s a warm weather outside. The reason is the water evaporating from our skin. Evaporating liquid consumes heat from a given surface. This is also a case of Freeze 75, which is filled by liquids with boiling point deeply below the frost point thus taking a lot of heat from a surface on which it is applied. Freeze 75 is non-flammable, non-explosive at all usual conditions and it also doesn´t attack plastics. It´s only advisable to be careful at components sensitive to sudden temperature changes. For absolutely highest safety in critical applications, the Freeze 75 Super is available, which is non-explosive at any circumstances.
