Important Notes When Ordering DamaTajhiz Air-Cooled Screw Chiller

• Manufacturing of air-cooled chillers with reciprocating compressors in other capacities is possible upon customer request.
• Compressors used in DamaTajhiz air-cooled screw chillers across all capacities are from globally recognized brands such as Copeland, Bitzer, and Danfoss.
• When ordering and purchasing a DamaTajhiz air-cooled chiller, carefully check its approximate dimensions to ensure it can pass through the entrance door and be transported to the installation foundation.
• When ordering and purchasing the required air-cooled chiller, make sure to obtain the approximate weight of the unit to prepare necessary reinforcement of the installation foundation and proper crane selection for unloading and installation.
• Changes in technical specifications and equipment used in DamaTajhiz air-cooled screw chillers are possible based on customer requirements and may affect pricing.
• When selecting air-cooled chillers, pay attention to the difference between nominal and actual capacity, especially considering outdoor design temperature in summer. Key factors include proper heat transfer surface design in condenser and evaporator (tube length, diameter, and quantity) to minimize the difference between nominal and actual capacity.
• Due to high costs of purchase, installation, and operation of HVAC systems including air-cooled chillers, it is strongly recommended not to rely solely on contractors’ suggestions and always consult experienced HVAC engineers for capacity selection.

General Features of Air-Cooled Screw Chillers

In general, air-cooled screw chillers have the following advantages:

• No compressor damage in case of liquid refrigerant return
• Smaller size compared to reciprocating chillers
• Significant energy and cost savings
• High efficiency and COP at full load operation
• Longer lifespan compared to other compressor types (with easier and cheaper maintenance)
• Smooth, low-vibration operation with reduced noise compared to other compressors
• Continuous and precise capacity control based on load demand (unlike step control between 25%–100% in other compressors, which may cause temperature fluctuations)
