Industrial chiller FAQ
Answers to common questions about buying, installing and maintaining an industrial chiller.
Where are industrial chillers used?
Anywhere a process or machine produces heat that must be removed at a controlled temperature: plastic injection and extrusion, mold and hydraulic oil cooling, laser and CNC machines, food and beverage lines, pharmaceutical production and building air conditioning.
What types of chillers are there?
Chillers are either vapour-compression (driven by a compressor) or absorption (driven by heat). Compression chillers are further divided by how the condenser rejects heat: air-cooled units use fans, water-cooled units use a cooling tower. Alborz builds air-cooled compression chillers and cooling towers.
How do I choose the right capacity?
Start from the heat load of your process, not from compressor horsepower. For a water circuit, Q = flow × specific heat × temperature difference: 10 m³/h of water warmed by 5 K carries about 58 kW. Actual capacity also depends on the leaving water temperature and the ambient air temperature, so send us your process data and we will size the unit free of charge.
Air-cooled or water-cooled: which is better for me?
Air-cooled chillers need no cooling tower, use no make-up water and are simpler to maintain, which suits sites where water is scarce or expensive. Water-cooled systems are more efficient at large capacities but need a cooling tower and water treatment. Our engineers can compare both for your site.
Which compressor brands do you use?
Scroll compressors, mostly Copeland. The compressor brand can be chosen by the customer. Refrigerant circuit components are Danfoss.
What warranty and after-sales service do you offer?
According to our catalog, chillers carry a one-year warranty and lifetime after-sales service covering all parts.
Do you supply chillers outside Iran?
Yes. We have supplied Alborz chillers to customers in Iraq. Send us your project details and location, and we will discuss the right model and how the order and delivery can be arranged for your country.
What should I send to get a quotation?
Your application (for example injection molding machine tonnage), the required water temperature, an estimate of flow or heat load, the ambient temperature range at your site and the available power supply. If you are not sure, describe the process and we will ask the right questions.
Why buy a chiller from a manufacturer rather than a trader?
A chiller runs for long hours and wears like any machine. Buying from the manufacturer means direct access to the engineers who built it, spare parts and the circuit drawings, which shortens downtime when something needs repair.
