However, if lower temperatures are required, the Low Temperature Chillers are designed for a -40° to +35°C temperature range. A dry cooler is essentially a fluid cooler that uses air, a relatively dry, non-liquid fluid to accomplish process cooling. Fluid coolers more accurately refer to cooling equipment that uses fluids to regulate process temperatures. Dry coolers are equipped with fans that pull air from the cooler’s exterior to sustain the heat exchange process. To ensure efficient process cooling, a suitable difference in temperatures between the cooling medium and the air within the dry cooler must be maintained. A dry cooler is a cooling device that uses air to achieve process temperature regulation. The cooling done by a dry cooler is based on the principles of sensible heat rejection. A typical unit requires a cooling medium channeled from an associated process that enters a dry cooler and exchanges accumulated heat with the air circulating within. Through our unmatched expertise and industry knowledge, we respond directly to the needs of businesses seeking digitalized and eco-conscious HVAC solutions.
8.2.2Switch on-air breaker of compressor and condenser, modify the setting-up value for temperature, after press the “ON/OFF” key (switch on/off key), the unit displays “On” state and then start the unit up. Because the special gravity of R22 is heavy than air, it will spread and may cause people to strangle if leakage occurs. So good ventilation has to implement if your air-cooled screw chiller is indoor. 7.3.3Water pipe system should install a paddle flow switch and interlock with compressor control to ensure enough water flow. 3)Adopt new technology DAC weave interior screw threat, high efficient heat exchange tube to ensure good cooling characters. 1)Fin type air-cooled condenser adopts imported high purely, seamless screw thread copper and special aluminum fin after mechanical expanding joint closely. Cooling circulating compressor absorbs low-pressure, over-heated refrigerant gasify from dry type evaporator and changes the refrigerant into high-temperature. The computer control system increases precision and reliability. It may regulate energy multi-steps to make output cooling energy to best match practical running load. Air cooled screw chillers are also widely used in plastic processing and plastic machinery including plastic injection molding, plastic extruders, and extrusion lines, blowing molding machines.

Manufactured in the United States the Air-Cooled Chillers from BV Thermal Systems are rigorously tested to ensure that chillers meetOur requirements before we would ship any unit to you. The Air-Cooled feature a hot gas by-pass which routes the hot, uncondensed refrigerant back through a reservoir coil thus eliminating the on/off cycling of the compressor. Utilization of the hot gas by-pass allows for greater stability and thermal protection for the pump, motor and compressor. On the other hand, industrial chillers incorporate refrigeration units in their cooling setup.
Chillers use coolant/chiller fluid which may be cooled by air or water in their associated condenser. This is the basis for the differentiation into water-cooled and air-cooled chiller variants. This device removes heat from a load and transfers it to the environment using a refrigeration system. This heat transfer device is the preferable cooling machine in power plants and other large-scale facilities. It is simply a system consisting of ethylene + water or water reservoir and circulation components. The cooling fluid is circulated from the reservoir to the equipment undercooling. There are also air-cooled chillers, which disperse heat-using fans. In this post, we review the difference between the two technologies, leaving the choice of which one to pick to you.
Recording operating conditions such as flow rates, pressures, fluid levels, and temperatures helps build a useful record of your system. While it was standard to do bi-monthly checks today’s continuous monitoring technology allows you to keep accurate daily logs that will help you narrow down maintenance issues before there’s a bigger problem. Heat Recovery Chillers from Motivair are designed to optimize overall chiller efficiency by simultaneously producing chilled water and hot water. Chillers used in plastic fabrication typically take on one or both of two roles, cooling the plastic products and cooling the machinery used to make them. The chiller units are also used to keep the barrel of the extruder, and hydraulics of the molding machine cool. This not only saves on energy but it also helps extend the life of the plastic fabrication equipment. Instead of utilizing a mechanical compressor the absorption chillers use a heat source to be the driving force behind the refrigeration cycle. These chillers typically use two liquids, one to cool and one to absorb.

Only sporadic periodic cleaning of air condenser coils might be needed if the air-cooled system is operating in a dirty environment in order to avoid the fouling. If fouling is accumulated, your system will develop higher operating discharge pressure, which may increase power consumption by the chiller. Water-cooled systems also have operation and maintenance issues; although it mostly depends on the quality of water used and surrounding conditions. Ozone, being a powerful oxidizer, can also help reduce this biological problem. When water evaporates from a cooling tower, it leaves behind all its solid matter. The only way to deal with this problem is to add water to the tower periodically to compensate for the lost water in a process which is called blow down. It prevents proliferation of dissolved solids, which may cause a bigger problem in the form of scale and rust formation. Generally, maintenance of this system is much more demanding than for an air-cooled system.
The final takeaway is that water-cooled chillers have a longer life, higher efficiency, larger capacity and refrigerant containment. Air-cooled chillers have a lower efficiency, yet are getting much better with technology advances, lower maintenance costs and less to install.

You might need to use chillers with multiple compressors that can work independently from one another so that if 1 compressor fails the chiller can still remain partly operational. Instead you should use multiple chillers, in parallel, of different sizes to meet the changing seasonal load at optimal performance with redundancy built in. For example you have a building with a cooling load of 2,200 Tons, then you should use combinations such as two 1,200 ton chillers or two 900 tones and a 500 ton or a 1,000 ton and two 700 ton chillers etc. Vapor absorption chillers will use a heat source to move the refrigerant around the system rather than using a mechanical compressor. The refrigerant in these chillers move around between areas of different temperature and pressure. Arrived in March 2014 to KIG were four immaculate Trane RTAA 125 ton chillers.
