The technological heart of the CGA product is the Aluminium ROLL-BOND exchanger. Such exchanger is made with a sandwich of two Aluminium sheets between which is obtained a canalization, thus allowing the flow of the convenient exchanging fluid (no matter if in a gas or liquid state).

The ROLL-BOND system features an excellent heat exchange, granting the 100% of primary exchange in force of the well-known high thermal conductivity of Aluminium.
The high production flexibility allowed by the technology permits to create a large number of different patterns for the channels, thus granting the exchangers to be adapted to any possible demand. Moreover the Aluminium sheet can be easily machined, bent, cut, painted and therefore adapted to every special application demand.

These extraordinary characteristics and the low unit costs support its use as a heat exchanger element in a large number of applications.

And - obviously - as evaporators for refrigerators: this is the consolidated use since over thirty years of continuous success.
