R290 (Propane) is refrigerant grade propane, used as an alternative to R404A and R407 series refrigerants in new refrigeration and air conditioning systems. R290 (Propane) is a Hydrocarbon and although highly flammable it is an efficient refrigerant that has a low Global Warming Potential (GWP). R290 (propane) can also be used as a substitute refrigerant. Being an organic compound (hydrocarbon), it has no ozone depletion potential and a negligible direct global warming effect. To take into consideration however, is a certain contribution to summer smog. Pressure levels and refrigerating capacity are similar to R22, and its temperature behaviour is as favourable as with R134a. There are no particular problems with materials. In contrast to NH3, copper materials are suitable as well, so that it can be used in semi-hermetic and hermetic compressors. Common mineral oils of HCFC systems can be used here as a lubricant over a wide application range. Polyol esters (POE) and polyalpha olefins (PAO) offer even more favorable properties. Refrigeration plants with R290 have been in operation world-wide for many years, mainly in industry – it is a "proven" refrigerant. Meanwhile R290 is also used in smaller compact systems with low refrigerant charges like residential air-conditioning units and heat pumps. Furthermore, a rising trend can be observed in its use with commercial refrigeration systems and chillers. Propane is offered also a

Q : How to anti-freeze for laser system chiller? A : Three tips to guard your water chiller through winter. Working 24 hours Run the chiller for 24 hours per day and make sure the water under recirculation status. Empty the water Empty the water inside the laser, laser head and chiller after done with using. Add antifreeze Add antifreeze into the water tank of chiller. S&A recommends the antifreeze which is exclusive used for automobile. Note: all kinds of antifreeze contain certain corrosive property, not to be used for long period. Please use clean pipes with deionized water or distilled water after winter, and refill deionized water or distilled water as the cooling water. Warm Note: because antifreeze contains certain corrosive property, please dilute it strictly according to usage note before adding into cooling water. Antifreeze Tips Antifreeze usually uses alcohols and water as base with high boiling point, freezing point, specific heat and conductivity for anti-corrosion, anti-incrustant and rust protection. Three important principles of chillers antifreeze need to aware during usage.

Dairies require accurate temperature control. There is only once chance to cool the milk, so you`ve got to get it right. Many years ago it was determined that maintaining milk at a cool temperature preserves it. By utilizing a water chiller, the milk is cooled and preserved. What does the dairy water chiller do for dairies? A chiller provides a reservoir of ice water to rapidly cool milk in the vat after processing or after milking. The ice water is pumped out of the chiller and circulated through the water jacket of the pasteurizer and then returned to the glycol water chiller. For faster cooling, food grade propylene glycol can be added to the water to lower the freezing point. Who needs a chiller? Not every processing operation requires a chiller. Water chillers are necessary if you are using the vat as a bulk tank and need to cool the milk to storage temperature (<45 degrees) or if you are bottling milk. Milk must also be cooled to 45 degrees before being bottled and you will need some method of chilling the milk. Note that many cheese makers and yogurt makers do not need chillers because they can just run tap water through the vat to cool the milk to culturing temperature (typically 110 degrees to 85 degrees). Yogurt can be packaged at culture temperature.

There is so much more that goes into the milk cooling process than most people think. The dairy industry has evolved rapidly over the years, specifically in regard to the way the dairy farm produces milk. Milk Cooling: Just a few years ago, the average dairy farm worked on a pretty simple process. The milk was generally pumped from the cows and then sent straight to a refrigerated storage tank. The milk was then cooled over time and delivered by truck loads to local stores. Dairy farms were pretty much all designed the same and were relatively the same size. There was not room for growth or expansion, and the tank that was used 20 years ago at these dairy farms was still capable of maintaining the farm's milk supply in the present. New Changes: Just like everything in life, things are constantly changing. Many milk producers are installing larger variable sized milking parlors that can service as many as eighty cows at one time in extremely large operations. In order to rapidly cool such large amounts of milk safely, dairy farmers have turned to process water chiller. Process chillers offer computer controlled cooler tanks, and can have the cooler and refrigerant systems do

Choosing a process water chiller for your HVAC needs can be quite the hassle. There are so many different types of HVAC cooling systems out there. Systems include rooftop packaged unit, variable refrigerant flow (VRF) systems, geothermal or air source heat pump systems, and many others. With all of the options available to manufacturers, process chillers still seem to be the HVAC system of choice for large commercial buildings and other facilities. But the process chiller`s popularity has not stopped competing technologies from trying to gain the top spot by manufacturers. Process chillers offer design flexibility, better comfort, and lower total life cycle costs – all of which can make them a perfect choice for high performance buildings. Choosing Your Water Chiller The main concern with any building is energy efficiency, which is the process chiller`s best quality. Water cooled chiller with capacities of 400 tons are more efficient than any other mechanical cooling technology. Water cooled chillers can also function over a wide operating envelope. Warmer water temperatures with a cooling tower can increase energy savings. Air cooled water chiller can minimize your compressor run time, which will also increase energy savings. Process chillers are the most efficient choice when deciding how to get the best performance, sustainability, functionality, productivity, and cost efficiency.

Why the temperature drops not be as fast as before? Some end users who use water chiller may have such experience, no matter what the chiller is. After using chiller for some period, they would feel that the cooling performance is worse than before. And that`s why chiller maintenance should be done regularly. The industrial water chiller is a device that provides constant temperature, constant current. They are widely used in the pharmaceutical industry, food industry, plastics industry, machinery industry and other fields. For this question, persons familiar with water chillers stated that generally speaking industrial chillers have a certain life expectancy. The good quality chiller can be used for more than ten years if used carefully and maintained regularly. [If the chiller was overloaded for a long period of time, the components of the industrial glycol chiller may be affected, which would lead to various failures in the industrial chiller," said a cooling specialist. There are many reasons for the poor cooling effect of industrial chillers, and the common reason is that industrial chillers were not maintained regularly. [If they were not regularly maintained, it will easily lead to more dust in internal parts of the industrial chiller, and the heat can not be effectively taken away. Also the equipment is in a high load running state for a long time, so the

The crowded 2018 Chillventa show was a mirror image of what is happening in the HVAC/R market. The HVAC/R sector continues to grow in volume, influenced by the increase in average temperatures, the growing need for personal well - being and the optimisation of production processes and quality of the food chain. The consequent rising interest among industrial funds towards the sector and consolidation by industrial groups through mergers and acquisitions has supported and is continuing to support the drive to technological innovation. We can refer to this as [smart" innovation, given that it concerns connectivity, natural refrigerants, electrification and integration with renewable energy, and simple human - machine interaction; in other words, all areas that contribute to making the undeniable opportunities offered by HVAC/R more accessible and socially acceptable. In terms of refrigerants, at Chillventa 2018 important developments were seen regarding solutions using R32 and R452B / R454B, useful for reducing the presence of R410A during the transitional period leading up to 2021 and the next important phase down of so called F - Gases. ( The regulation puts in place HFC phase down from 2015 to 2030 by means of a quota system and sectorial bans on high GWP refrigerants ). Even though the R452B / R454B solutions are de

The printing industry features a multitude of different technologies that can be used, from traditional printing (such as offset printing, rotogravure printing, screen printing, etc.) to digital printing (for example, inkjet or laser). The processes underlying these technologies are quite different, but they all share one need: to control humidity in the processing and storage environments. Storing or printing paper in a place where humidity is outside of the specified range can lead to a significant COST item, due to lost productivity (machinery stoppages) and rejects (print defects or low quality products). What are the reasons for these problems? Firstly, dimensional variations and the loss of substrate flatness. Paper is a hygroscopic material that, when its moisture content is not in equilibrium with the humidity of the surrounding air, gives up or absorbs moisture, thus varying its dimensions. For example, for a 16 x A4 print sheet, a 10% variation in ΔRHroom can create a 2 mm difference!

Why plastic process chiller? Process cooling in plastic processing is necessary as considerable amounts of heat have to be removed from the material, mold or machine, such as plastic injection, plastic extruding (sheet extrusion or profile extrusion), bottle blowing and film blowing etc. Before shaping, thermoplastic materials such as polypropylene, nylon and PET etc thermoplastic must be heated to their molten temperature. When molten, they can then be manipulated (injection molded, extruded etc) to a new shape. Finally they must be solidified them via cooling. what plastic process chiller do? Cool the hot plastic that is injected, blown, extruded or stamped to maximize productivity and improve the quality. cool down the plastic process equipment that is used to produce plastic products, such as hydraulics of the molding machine, gear box and barrel of the extrusion machine, to save energy and extend lifetime of the machine. We are professional to design any independent water chiller as per you cooling requirement, for any types of plastic pressing machine, such as plastic injection machine, sheet extrusion machine, profile extrusion machine, bottle blowing machine, film flowing machine, etc. Contact us now and you will

While sizing a water chiller for your application, you need to entertain a few factors. First, let us understand the functioning of a chiller. A chiller is basically a compressor based cooling system which appears quite similar to an air conditioner except a different functioning. It is used for cooling as well as controlling the temperature of a liquid rather than air. The chiller will ensure to provide a stable flow, temperature and pressure once it has been set on a program as per the specific needs of a user. The Emerging Application Areas Chiller is also known as Chilled water cooling systems. It has become a preferred choice for various institutions where commercial conditioning repair is required. Schools and hospitals form good examples of the same. To understand chiller better, we can say that it is a compressor based cooling system which is similar to an air conditioner but it cools liquid and not air. Big commercial buildings which need a substantial amount of cooling use water chiller because of its cost effective feature. There is a decreased hazard now by not having refrigerant pipes surrounding the building. Harmful particles are tried keeping out of the system by using an internal strainer. Advantages of Installing a Chiller Air cooled chillers can be installed in open areas like parking space, roofs or even at the ground level areas. It will have all the benefits of a low installation cost as well as maintenance. They can also do this without using a plant room, c

If you want to have reliable temperature control over your fermentation and storage temperatures, we recommend looking into a complete glycol water chiller for your winery. A properly set - up / sized glycol system will allow you to independantly control your fermentation vessels, storage tanks and cellar - all at the same time with a single machine. How Does It Work? At the heart of a glycol system is the glycol chiller itself. A glycol water chiller is actually a refrigeration system that is used to cool a bath or tub of an antifreeze called "propylene glycol", or just "glycol" for short. This cooled liquid is pumped though a looped circuit of tubing connected to the input and output sections of the glycol chiller. This is your main cooling line. For every vessel you want cooled, just connect the heat-exchanger (ex: a jacket on a tank, a stainless steel plate exchanger, a stainless steel cooling snake, etc.) to the inlet and outlet legs of the main cooling line. Once connected, glycol will now circulate through the heat-exchanger and the vessel will be cooled. Control The Flow: Glycol is usually chilled below the freezing point of water. This makes it very effective for cooling, but if you would like to maintain a temperature higher than freezing for your wine, you will need to adjust the flow rate of the glycol through the heat exchanger. This can be done in one of two ways:

There are a variety of industrial and medical applications that require years of reliable refrigeration. The latest technology, which we specialize in at Amrta air conditionng, will ensure that your medical lab or industrial facility can achieve steady temperatures for every type of process. With our leased water chiller, you can maintain constancy while also being able to customize the temperature of each process through an easy to configure computerized dashboard. We thought it would be a good idea here to explain how a recirculating chiller works, especially to help a company in need of chiller leasing to keep their processes constant. We believe that our clients should be able to source chillers of the highest quality without paying too much for electricity and water. Exploring the Recirculating Water Chiller A recirculating chiller typically runs on a pump, such as a centrifugal pump. It works in a cooling loop, which begins with the compressor, continues with the condenser, moves to the expansion valve, and concludes with the evaporator. After the evaporation process is complete, the cooling loop begins again with the condenser. Each component in a recirculating chiller depends on the integrity of all parts within the unit. For example, if there is a blockage within the unit, then it will not function according to its design, and the temperatures that it provides for medical or industrial large processes will not be consistent.

What is free cooling and how can it reduce air conditioning operational costs? Free cooling provides significant opportunities to generate energy savings. It can take effect when the difference between the outside supply and return temperatures is as little as 1°C. This means that, in a 24/7 data centre with a typical room temperature of 24°C, over 95% of the year can be spent with free-cooling active. Concurrent free cooling In addition to energy savings through reducing the need for mechanical (DX) cooling, concurrent free-cooling also maximises the part-load efficiencies of components such as EC fans, inverter-driven pumps and centrifugal compressors. The variable speed control on such components allows load to be very precisely matched to cooling duty, reducing energy consumption and unnecessary wear. EC fans for example are up to 70% more efficient than AC fans at part-load. The use of temperature sensors and sequencer controls allows for cooling to be staged, ensuring a smooth transition from mechanical cooling to air free cooling. On sites with an air

How To Choose An Industrial Water Chiller Choosing the right size recirculating chiller adds to the economies of its use. The optimum size needed is based on the amount of heat your application is generating, plus additional power to maintain temperature under varying loads. Normally the manufacturer of the equipment you are cooling will supply heat removal information, which will include BTU/hr or watts to be removed along with flow rate and desired and inlet and outlet temperatures for the equipment. If information isn’t available, here’s how to calculate the heat load of your system: BTU/hr = (T1-T2) x gpm x 60 min/hr x 8.33 lb/gal x Cp T1 = temperature of coolant leaving the equipment, deg F T2 = temperature of coolant entering the equipment, deg F gpm = gallons per minute of coolant flowing through the equipment Cp = specific heat of coolant; Water = 1.0 Measure temperature with the same thermometer if possible of with two thermometers of known accuracy. Measure gpm using a flowmeter of by collecting the coolant in a known volume for a given period of time. Additional Considerations If ambient temperature of the cooling locati
