Applications and models

Intersam industrial ceiling evaporators with double air distribution are placed in conservation chambers and refrigeration of all kinds of genres.

This Intersam range is composed of four main series, depending on their use for high ( IPIA), medium (IPIM), low (IPIB) and very low temperature (IPIT).

Industrial ceiling evaporators features

As for its high performance evaporator coils, they are built in 1/2 ”fluted copper tube with fins. corrugated aluminum, with spacings of 4.2, 6, 8 and 10mm.

On the other hand, the frame is made of sheet aluminum and is provided with protective collars. It has a Venturi type production system for the application of thermostatic expansion valves.

Regarding its exterior structure, the manufacture is made of aluminum painted in polyester RAL-9018 color high resistance. The entire structure is compact and highly rigid, thus avoiding vibrations. It should be noted that all its parts are easily removable, which makes maintenance easier.

The units are fitted with helical fans with high performance protection grilles as standard and are provided with 400, 500, 630 and 800mm diameter motors. They are three-phase motors for 400V / 50Hz, with IP-54 degree of protection, with external rotor and low consumption. Its bearings are provided with a special grease for low temperatures, down to -50ºC. The motors are connected to a watertight general box, according to IP-55 regulations.

Finally, defrosting is carried out using 230V electrical resistances that are built in armored stainless steel tube and are inserted inside the battery and the tray. These resistors avoid derivations thanks to their vulcanized ends and are connected to a watertight junction box.

The models in this range can be supplied with defrosting resistors.


We provide you with a wide variety of options when configuring your equipment. These options allow, for example, modifying the coil fins and tubes or applying anti-corrosion treatments when the installation conditions require it, among others.

As for defrosting, you can opt for an electric defrost on battery and on a tray, by hot gas in battery with resistance on a tray, but you can also opt for a defrosting with an isolated drain tray.

In the downloadable brochure on this page you can consult in more detail all these and other options that affect fans and equipment valves. .

All the options to be included in the equipment must be made upon request and under the prior study of the technical department of Intersam. The powers of the forced draft evaporators are checked in a dry atmosphere according to the ENV-328 standard. The nominal powers indicated in this catalog correspond to the test powers (SC2) multiplied by a coefficient (latent heat factor), in order to include the increase in capacity caused by the condensation of water vapor on the surface of the evaporator. This factor varies according to chamber conditions: it increases for high interior temperatures and decreases for low interior temperatures .
