3. Air cooled industrial chiller applications
Air-cooled chillers are intended for outdoor installation and operation. Air-cooled machines are directly cooled by ambient air being mechanically circulated directly through the machine's condenser coil to expel heat to the atmosphere. No remote cooling tower is typically required with packaged air-cooled chillers. Eurostars air cooled industrial chillers are mainly applied in the following fields:
Induction heating equipment, diathermy equipment
High frequency, medium frequency power supply, IGBT quenching equipment
Die-casting machines, injection molding machines
Rectifier equipment, resistance welding machine
Single crystal furnace, continuous casting mold machine, glass melting furnace
Food, chemical, air compressors, central air conditioning

7.Industrial Chiller Installation Precautions
Although Eurostars provides chiller installation guidance service, if you already have some experiences in chiller operation and installation, you can choose to proceed by yourself to save labor cost and time.
But pay attention to a few more details, the chiller will return you better performance and longer service life. 
Here are the precautions that you need to know before proceed:
(1)Selection of installation location.
For air cooled chillers,we need an open space with good ventilation. Make sure there is no barriers or walls within 1m around it, otherwise there will be trouble for air flow and heat dissipation. The point is we need to make sure the heat out from the chiller can be removed outside, instead of circulating within a small space.The distance to block also ensures space for maintenance. If you are planning to install an air cooled chiller in a space with poor ventilation, you need to consider mounting air duct on top of the chiller near the condenser fans, so to make sure heat removal.

In below picture, Case1 is a chiller located in drafty condition, Case 2 is a chiller located in poor ventilation environment.


For water cooled chillers, we just need to reserve enough space for maintenance, as the heat from the chiller is removed through water to the cooling tower.
(2)Ground for locating the chiller.
 Industrial chiller must be placed on solid and level concrete floor which is able to support the weight of the chiller. The levelness of the floor should be within 6mm. Chillers vibrate when running, if the floor is not solid nor flat, the chiller will easily displace, especially for portable chiller with casters. Rough ground will amplify the vibration of chiller, which will lead to serious troubles after long time running.
 
For a large chiller unit, say models higher than ESSA-15IDTN, we need to build concrete foundation for it. It is necessary to make 50-100mm absorbing gap fill with sands or pitch all around the foundation. On the foundation, there should be bolt holes for fastening the chiller base and concrete foundation together.
 
After the above things are done, let's put the chiller on the foundation. Then we need a level meter to check if there is any incline. If there is, put parallels between chiller base and concrete foundation to adjust it.

(3)Pipe, wire and filter preparation
*In a Eurostars chiller specification sheet, there is connection size and max amps for the unit. Correctly select the pipe and wire size by referring to it.
*If you are not so confident with the water quality in your location, filtration is a necessity to avoid the chiller water circuit from trouble.Y type filter is suggested.
*Make sure you are clear that which port you should connect to. Although there will be sign of inlet or outlet of every Eurostars chiller, double check it please.
