Chillers typically cool water, which is then circulated to provide comfort cooling throughout a building or other location. Chillers can be classified by compressor type, including centrifugal and positive displacement. Chillers used to cool industrial processes are discussed under Industrial Process Refrigeration. In May 2019, Frigel Firenze launched new modular chillers; 3FX chillers. Seven models come with screw compressors and the remaining five come with scroll compressors.
Standard set point range is 20°F to 65°F (-7 to 18°C) with extended range from 0°F to 80°F (-18°C to 27°C). HVAC chiller suppliers offer only the chiller and often aren’t able to provide reservoirs, pumping systems and controls. Berg engineers work with you to custom design the water cooled chiller package that will meet your economic and functional needs. The process of the metering of the refrigerant and resulting pressure drop causes the temperature of the refrigerant to drop. This water cooled chiller comes pre-piped and pre-wired and requires a minimum of installation effort and occupies a small amount of floor space. The cost of water can add up quickly, especially if process equipment is running for several shifts a day.
These types are water-cooled chillers and air-cooled chillers, with each offering their own set of advantages and disadvantages. It should be noted that although industrial chillers are used to cool down pieces of equipment, they aren’t actually “chilling” anything. An industrial chiller does not make an object colder, rather, it simply removes the heat. Our industrial air chillers and water chillers remove heat from either water or air and circulate it through a heat exchanger to cool the surrounding air or equipment. Never settle for a chiller not designed for your specific needs to save money. You’ll spend more over time due to inefficiencies in the misuse of the cooler.
Large chilled water hoses are used to connect between rental chillers and air conditioning systems. Artificial Intelligence continues to advance in everyday practical applications. Machinery such as chiller systems will benefit from AI algorithms that can detect potential failures before they occur. Predictive maintenance leverages the collection and analysis of chiller system operational data to determine when maintenance actions should be taken prior to catastrophic failure. As chillers systems represent the heart of most modern HVAC systems, the prevention of catastrophic failures that produce significant “downtime” will save on emergency repair costs as well as reputation.
Building occupants similarly carry great expectations, that the HVAC system will function as intended . to create a comfortable interior environment regardless of the conditions external to the building. Our custom-capable product line includes an industrial-grade lineup of in-stock items available for quick shipment. You can also choose to partially or fully customize our chillers to meet your specifications.
When your cooling water supply isn’t cool enough, let a PCR water-condensing chiller provide the temperature you need. Built like the big expensive chillers yet compact enough to fit where you need them without breaking your budget. A distinct advantage of using water is the fact that it is non-corrosive, has specific heat value, it is non-toxic and inexpensive.
In addition to standard I/O and RS-485 serial communications, analog and DeviceNet™ communications are optional. Rack mounting recovers desktop or floor space, permitting stacking of related devices and mobility, depending on the rack style. The heat is then removed from the fluid by an air or water-cooled refrigeration circuit. Coolant temperature stability is ±0.1°C within a set temperature range of 10 to 35°C.
One can select chiller variations that can be analyzed based on initial cost and overall system operating costs. Clearly, there are multiple different chiller options, and careful analysis, rather than a blended kW/ton value, is required to make the best selection for your situation. For operating costs, VPF systems will always have lower operating costs as there is less pressure drop in the system due to fewer pumps and accessories at the pumps, but also because the pumps will be more efficient. The VPF pumps allow the designer to select larger, more efficient horsepower pumps instead of smaller, constant volume, low efficiency circulator pumps typically found on the primary side of the primary-secondary system.

We focus on bringing our unique, innovative stamp to each of our industry-leading technologies. From compressors and blowers to gas generators, dryers, controls, and service, our ultimate goal is to deliver outstanding value. Portable Air has one of the largest air-cooled chiller fleets in the industry. Our vast selection of portable, trailer-mounted air-cooled chiller units is guaranteed to increase your productivity resulting in less downtime for your project. For over twenty years Chillking has been building industrial and commercial chillers.
Optimize your buildings’ energy efficiency with today’s advanced chiller technology. If ambient temperature of the cooling location is above 20°C, add 1% to the calculated wattage for each 0.5°C above 20°C. Future growth cooling needs or variability of heat output of existing unit. If ambient temperature of the cooling location is above 68°F, add 1% to the calculated BTU/hr for each 0.9°F above 68°F. Select a circulator when temperature stability is whats desired, select a chiller when heat removal is whats desired.
Fluxwrap by North Slope Chillers is a convenient and simple temperature solution that’s not afraid of double-duty. Whether you seek to heat or cool, liquid from your compact chiller unit circulates through Fluxwrap, regulating the temperature of your containers and equipment and providing consistent temperature control. Large commercial buildings that require a substantial amount of cooling often use water chillers because they are cost effective and there is a reduced hazard by not having refrigerant piped all over the building.
Also, load programs can quickly and easily apply actual building rate structures to an analysis, including any ratchet charges, consumptions charges, and demand charges. To properly analyze each option, chiller selections should be provided with an unloading curve in at least 10% load increments. This is sufficient for an analysis and will yield relatively accurate results without much effort. Selecting the right chiller is generally dictated by capacity, and there are many philosophies on the best way to control, operate, and calculate system operational costs. If you have a building with a medium to large cooling load then its recommended that you do not use only one oversized chiller to handle the entire cooling load. This is not efficient and if it fails you will have no cooling capability left.
Cooling and climate control systems, in contrast, are usually used for cooling spaces where precise and constant temperature control is not as critical. HEC recirculating chillers satisfy low capacity temperature control demand in the range of 140 to 1200 watts. A refrigerant-free, thermoelectric peltier element controls temperature from 10.0 to 60.0°C, with precision of ±0.1°C under stable load conditions. 15 alarms support functional troubleshooting, and can be observed on the LCD display or over serial communication. Low noise and vibration, compact dimensions and flexible power requirements are suitable for laboratory benchtop service. CustomChill units are the best way to provide safe, accurate, highly reliable thermal control of your system.
The absence of a compressor in the absorption coolers results in direct or indirect firing and controlling the capacity through the amount of heat entering the system. These pumps handle the entire system head at the required system flow rate. The system minimum flow is maintained by using a flow meter or measuring the pressure drop across the chillers to determine system flow to control the bypass valve. A sample project is also presented to illustrate the variation in initial chiller costs.
