NSC Chiller Selection Guide - North Slope Chillers
Step 6: Final selection. Finally, consider that the remaining application requirements such as power characteristics, control options, footprint, agency listing, colour, etc. are met by the selected standard Pfannenberg chiller. Choosing a standard chiller will bring you greater reliability, easier service with common spare parts and global
Case studies of the chiller selection process are provided. Sample chiller bid forms are also provided (Chiller Bid Form and Simplified Chiller Bid Form). Topics include types of flow and temperature sensors, styles of and selection criteria for control valves, controller requirements and interfacing issues, performance monitoring, and
As each industrial environment is different, Pfannenberg designed a 6-steps guide to help you select the proper chiller for your application: Step 1: Determine the heat load. It is
1- Minimum chiller capacity. When choosing a cool air chiller, the characteristics of the area used and the capacity of the device used are taken into account. Where the area used is very cold and the temperature difference between day and night is very large, cool air chillers are preferred. However, in such cases, it should be
Suggested Chiller Fluid. The most common and acceptable coolant is a mixture of 50% distilled water and 50% glycol (polycool EG-25). This combination will provide the best results for set-point temperatures between -25°C and +80°C (-13°F and +176°F). Although ethylene glycol is not required for set-point temperatures above freezing (0°F

The predominate types of chiller compressors are scroll, screw and centrifugal. The capacity of scroll chillers nominally ranges from 10 to 300 tons. To provide larger capacity, a scroll chiller will typically

When specifying a chiller installation, a working knowledge of chiller performance factors is crucial to obtaining the right product fit. 3. Process fluid performance. The main factors to bear in mind when considering the appropriate cooling fluids for a process are their performance characteristics and their equipment compatibility. 4.
Industrial chillers typically come as complete packaged closed-loop systems, including these components: Chiller unit. Evaporator - Typically one of two types of evaporators are used: Shell and Tube Evaporators and Brazed Plate Evaporators. Compressor - Typically one of four types of compressors are used: Reciprocating. Centrifugal. Scroll. Screw.
The evaluation criteria used to select a chiller involve the owning costs and the operating costs. The owning costs include acquisition, installation, and replacement costs; salvage value; discount rate and financing method; and fixed or periodic costs such as insurance and property taxes. These costs are exclusive of costs associated with
All Capacities Air-cooled chillers without condensers must be rated with matching condensers and comply with the air-cooled chiller efficiency requirements. 1.2.2.2 Water Cooled Chiller Table 2. Water-cooled chiller efficiency requirements. Equipment Type Size Category Units Path A (For chillers designed to operate near full load capacity)
Step 6: Final selection. Finally, consider that the remaining application requirements such as power characteristics, control options, footprint, agency listing, colour, etc. are met by the selected standard Pfannenberg
Chiller selection step 1: Specify circulated water temperature. The temperature of the circulating water is determined from the optimal temperature of the workpiece (device or process subject to cooling by the chiller). (1) Determine the optimum temperature of the workpiece to cool. (2) Determine the temperature of the circulating water.
Chiller selection requires a great deal of technical knowledge as refrigeration technology has changed considerably in the last 20 years. If you''re considering replacing a chiller which has come to the end of its lifespan, looking to upgrade to a more
