Industrial Chiller Systems Built Around Real Cooling Loads
An industrial chiller system should be matched to process, building profile, condenser side, maintenance access and energy target. Proper first-pass design avoids oversizing, poor part-load operation and field changes after delivery.
01
Unstable Load
Variable production facilities, data halls and grow rooms require capacity control, not just one nameplate number.
02
Wrong Heat Rejection
Water access, ambient temperatures and cooling tower limitations determine if air, water, or evaporative equipment is suitable.
03
Weak Part-Load Fit
Full-load COP only does so much for assessing the real energy profile of the plant. IPLV and load hours should be considered together.
04
Service Risk
commissioning, replacement parts, control training and warranty coverage are just as important as compressor selection.

Koven Load-to-Chiller Fit Map
Air-Cooled vs Water-Cooled vs Evaporative vs Magnetic Bearing Chillers
When comparing industrial chiller models, buyers need more than a brand name. The important consideration is which condenser approach, capacity band and maintenance style will suit the site.
| Decision Dimension | Air-Cooled Chiller | Water-Cooled Chiller | Evaporative Chiller | Magnetic Bearing Chiller |
|---|---|---|---|---|
| Site condition | Best where tower water, pumps or water treatment are hard to support. | Best where tower loop and plant-room support already exist. | Best where outdoor heat rejection needs better condenser performance in hot weather. | Best where the plant runs many hours at changing load. |
| Capacity band from Koven data | 30-760 RT screw; 63-160 RT scroll |
93-1,000 RT screw | 46-210 RT scroll; 70-1,000 RT screw |
170-1,250 RT |
| Part-load review | Check ambient profile and fan power. | Check tower water temperatures and pump strategy. | Check water quality and drift control. | DOE notes that magnetic-bearing chillers gain more value in plants with many part-load hours. |
| Maintenance profile | Focus on condenser coil access, airflow and controls. | Focus on water treatment, tubes, pumps and tower condition. | Focus on water quality, condenser cleanliness and outdoor access. | Oil-free bearing design can reduce oil-related service work, while controls skill still matters. |
| Procurement risk | Noise, high ambient design and roof load need early review. | Tower package, water treatment and plant-room layout need scope clarity. | Water plan and local climate data must be agreed before purchase. | Power quality, controls support and technician training need a clear plan. |
Compare COP and IPLV together
DOE FEMP purchase guidance recommends considering both full-load efficiency and IPLV. This advice is valid as most commercial chiller plants do not operate at maximum capacity full time.

Chiller System Choices Are Moving Toward Part-Load and Refrigerant Review
Selecting modern chillers has become more than just determining the cooling capacity. Customers also consider factors such as the number of hours the plant will operate at part load, the ease of service access, the preferred refrigerant path, and the overall long-term plant costs.
IPLV belongs beside COP
AHRI lists ANSI/AHRI 550/590 and ANSI/AHRI 551/591 for rating water-chilling packages and heat pump water-heating packages using the vapor-compression cycle. Ask for both full-load and part-load data during evaluation.
Low-GWP planning affects specs
EPA describes the AIM Act HFC phasedown and sector restrictions that apply to refrigerants used in air conditioning and heating equipment. Review refrigerant choices, such as R1234ze and R1234yf, early in the design process.
Maintenance is part of TCO
DOE suggests that the elimination of oil in magnetic-bearing designs can reduce the maintenance costs associated with oil-related service issues. However, this is dependent on factors such as controls setup and load profile.
Standards belong in the RFQ
Use ANSI/AHRI 550/590 for I-P rating language and ANSI/AHRI 551/591 for SI rating language when a project asks for rated chiller data. Keep ISO, local electrical code and witness-test forms separate from capacity claims.

Open ToolChiller Buyer FAQ
How much does an industrial chiller cost?
The purchase price is affected by several factors, including capacity, type of compressor, condenser type, refrigerant, control features, the extent of testing required, shipping logistics, and the location of the project. Comparing a 100 RT modular chiller with a 1,100 RT magnetic bearing centrifugal chiller, you’ll find the purchasing processes differ greatly. Start by submitting the load profile, desired chilled-water temperatures, condenser limitations, power supply, and site plans to receive comparable quotes. Compare purchase prices, energy consumption, maintenance access, and the risk of a shutdown.
Which is better, air-cooled or water-cooled chillers?
Air-cooled chillers are ideal for installations without access to tower water. If you already plan to install and maintain a tower, water pumps, and water treatment systems, water-cooled chillers can offer significant energy savings.
How do I choose between screw, scroll, centrifugal and magnetic bearing chillers?
Scroll chillers are suitable for smaller cooling loads and modular staged plants. Screw chillers are widely used in industrial and commercial chiller system applications in both medium and high-capacity ranges. Centrifugal and magnetic bearing chillers are best suited for large central plants, with magnetic bearing chillers being particularly effective in situations where part-load efficiency and oil-free compressor operation are essential.
What chiller type is best for a data center?
Data center owners prioritize reliable operation, consistent chilled-water supply, precise control at part load, and ease of maintenance. Koven Air has provided a two-unit installation of 1100 RT water-cooled magnetic bearing centrifugal chillers to a data center facility. The selection should be based on redundancy requirements, condenser water conditions, controls, power quality, and a clear local service plan that aligns with the PUE target of the facility.
What is the difference between a commercial chiller and an industrial chiller?
A commercial chiller often serves comfort cooling, whereas an industrial chiller may be used for production process, data room cooling, cold storage, or controlled agriculture.
Do magnetic bearing chillers use oil?
Magnetic bearing chillers suspend the compressor shaft using magnetic force, eliminating the oil system found in many traditional compressors. This feature, along with the reduction in oil-related maintenance, is highlighted by DOE as a benefit of magnetic bearing technology. However, to ensure proper functioning, the facility still needs a skilled controls technician, consistent water quality, stable power, and appropriate commissioning. An oil-free compressor cannot compensate for an inadequate plant design.
What information is needed for chiller sizing?
When selecting a chiller, you should begin by providing the required cooling capacity, the desired inlet and outlet water temperatures, ambient design conditions, the process fluid being cooled, the available power supply, site elevation, and the permissible equipment footprint. Next, provide the annual load profile, the desired redundancy level, refrigerant preferences, and any local service restrictions. Koven Air can assist in reviewing this information before making a model selection.
Does Koven Air provide installation and commissioning support?
Yes. Koven Air can send qualified technicians to the site to provide installation guidance and troubleshooting assistance. Any issues encountered within the warranty period are promptly addressed.
