Produces chilled water in a single unit
Houses the evaporation-compression cycle in a single package; the evaporator, compressor, condenser and control system all come together.

Chillers
A packaged cooling unit that produces chilled water through an evaporation-compression cycle. It rejects heat directly to the atmosphere in air-cooled types, or through a cooling tower or dry cooler in water-cooled types.

Why it matters
What does a chiller do?
From comfort cooling to process cooling, a chiller handles this job in a single package wherever a system needs chilled water.
Air-cooled or water-cooled option
An air-cooled type is preferred when the water supply is limited; a water-cooled type working with a cooling tower or dry cooler is preferred when higher efficiency is required.
Capacity staging and part-load efficiency
Scroll, screw or centrifugal compressor options keep the unit running efficiently even under the facility's variable load.
A shared solution for comfort and process cooling
The same operating principle is applied at different scales, from an air handling unit's cooling coil to industrial process cooling.
Types
Sub-types of chillers
All three produce chilled water; what sets them apart is where they reject heat and their compressor design.
Air-cooled chiller
Rejects condenser heat directly to the atmosphere; needs no additional water circuit and is installed outdoors on a roof or on the ground.
- Requires no water source
- Simple to install and maintain
- Performance is affected by outdoor temperature
Water-cooled chiller
Rejects condenser heat into a water circuit, which is then rejected to the outside through a cooling tower or dry cooler.
- Higher COP (efficiency)
- Requires a cooling tower or dry cooler
- Common in large-capacity central-plant applications
Screw / centrifugal, multi-compressor chiller
Delivers high efficiency even at part load, using multiple compressors or a speed-controlled compressor.
- High efficiency at part load
- Preferred at large facilities with variable loads
- Requires more complex control
Selection criteria
What data determines the right chiller?
Capacity alone isn't enough. Once the six points below are clear, the choice narrows to a single model.
ParameterWhy it mattersWhat we need from you
Cooling capacity
The chilled water flow rate and the inlet/outlet temperatures together determine the capacity.
kW
Heat rejection type
Whether the unit is air-cooled or water-cooled; determines the need for a water source and a cooling tower/dry cooler.

Refrigerant type
R134a, R410A, etc.; determines environmental regulations and the pressure class.
Refrigerant name
Compressor type
Scroll, screw or centrifugal; determines the capacity range and part-load efficiency.
Compressor type
Chilled water temperature regime
Inlet/outlet temperatures (e.g. 12/7 °C); determines the evaporator size and the flow rate.

Electrical supply and control
Power, phase and the need for integration with building automation determine the control selection.

FAQ
Questions from the field
The questions we hear most often when quoting chillers.
What is the difference between an air-cooled and a water-cooled chiller?
An air-cooled chiller rejects condenser heat directly to the atmosphere and needs no additional water circuit. A water-cooled chiller instead carries this heat to a cooling tower or a dry cooler through a water circuit; it generally runs at a higher efficiency but needs extra equipment and maintenance.
How is chiller capacity determined?
The required chilled water flow rate, the inlet/outlet temperatures (for example from 12°C to 7°C) and the outdoor design temperature are evaluated together to determine the capacity (kW).
How do you choose between scroll, screw and centrifugal compressors?
Scroll compressors are preferred at small and medium capacities, screw compressors at medium-to-large capacities, and centrifugal compressors in large, continuously running applications; the part-load profile and the energy-efficiency target influence the choice.
Does a chiller need a cooling tower or a dry cooler?
Not with an air-cooled chiller. With a water-cooled chiller, a cooling tower or a dry cooler is needed to reject the heat from the condenser circuit.
Do you only serve Istanbul?
No. While our office is on Istanbul's Anatolian side (Ataşehir), we supply and ship across Istanbul's European side, the surrounding provinces and the Marmara region, and Turkey as a whole — covering your equipment end to end, from a single source.
