GLYCOL COMMERCIAL CEILING AIR COOLERS
Applications and models
Intersam commercial glycol ceiling coolers are flat, low-rise and they are placed mainly on the roofs of the chambers. Its double air distribution achieves optimum air distribution throughout the interior of the enclosure. The range is composed of three main series, according to their use for high (IPA), medium (IPM) or low temperatures (IPB).
Glycol commercial ceiling air coolers features
The evaporator coils of these units are high performance and are built in 1/2 ”fluted copper tube and fin corrugated aluminum with gaps of 3.5, 6 and 8mm.
The frame, made of aluminum sheet, is provided with protection collars. This frame has a Venturi type production system for the application of thermostatic expansion valves.
Regarding their exterior structure, they are manufactured in aluminum painted in high resistance RAL-9018 polyester color. The vibrations in these machines are avoided thanks to the fact that their entire structure is compact and highly rigid. All its parts are easily removable for maintenance.
These evaporators are fitted as standard with helical fans with high performance protection grilles and are equipped with 315 or 350mm motors. diameter. Single-phase for 230V 50Hz, with degree of protection IP-54, with external rotor and low consumption. All motors are connected to a watertight general box, according to IP-55 regulations.
Finally, defrosting is carried out with 230V electric heaters built in armored stainless steel tube. Its vulcanized ends avoid derivations and are inserted inside the battery and the tray. They are connected to a watertight junction box.
All models in this range can be supplied with defrosting heating elements.
Options
We provide you with a wide variety of options when configuring these series. These options allow, for example, modifying the coil fins and tubes, applying anti-corrosion treatments when the installation conditions require it, incorporating heat coils, etc.
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 see in more detail all these and other options that also affect fans or the possibility of installing the complete valve kit (expansion valve, solenoid valve and shut-off valve) .
All 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 tested 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 condensation of water vapor on the evaporator surface. This factor varies according to chamber conditions, it increases for high interior temperatures and decreases for low interior temperatures, as indicated in the table attached to the brochure.
