Ice rink chillers are newly developed refrigeration machines for the ice skating rink and ice rink arena application. Oumal chiller is specialized in design and manufactures various models of ice rink chillers and ice rink refrigeration system. Oumal manufactures refrigeration equipment designed specifically for ice skating rinks. Oumal  does it all chillers From small 4 ton packaged residential chillers to 500 ton industrial grade refrigeration plants’. Our engineers will select the right chiller for your ice rink project. We offer a wide range of chillers and sizes from small quiet chillers for residential ice rinks to air and water cooled commercial/industrial chillers for larger, full size or multiple ice pad facilities. Ice rink chillers manufactured from Oumal equipped with hermetic scroll compressor or semi-hermetic screw compressor, the cooling capacity range is from 1.5ton to 300ton with the temperature controlling range from -10℃ to -30℃. For an ice rink project, the refrigeration system or the ice rink chiller is the most part. Because this refrigeration system is providing constant cooling source to make sure the ice inside your ice rinks yard keeps at a proper temperature. A refrigerated ice rink utilizes an ice rink chiller that draws the heat out of the ice, ensuring it stays frozen despite temperatures rising well above freezing. Yet the chiller won't run if the ice sensor reads a temperature below its threshold of operation. The size of the chiller depends on the size of your ice rink. A 4-ton ice rink chiller is about the smallest available. It is adequate for rinks up to 800 square feet (20' x 40') 10 tons is a common size chiller for ice rinks. A 10 ton chiller is adequate for up to 1800 square feet (say, 32' x 56') Want an Olympic-sized hockey rink (100 feet by 200 feet)? Order yourself a massive 200 ton hockey rink chiller! There are, of course, various other chiller sizes and we will build you a custom-sized chiller for your ice rink.  

Without proper temperature regulation, a lot of manufacturing processes that are heat sensitive will either deteriorate or result in an altered finished product. Various types of industrial chillers are available for widespread use in metallurgy and industrial welding. Industrial welding chillers for resistance welding like spot welding, MIG welding, and TIG welding can help improve product quality and process efficiency. Welding chillers are commonly used for resistance welding and its variations such as spot welding, as well as TIG and MIG welding. Chillers or recirculating water systems are used to control electrode tip temperature. Over time, chillers have progressively replaced recirculating city-water systems because they are less costly to operate and can provide more accurate temperature control. Welding heat is the most significant parameter to control, because it directly correlates with how much current can be consistently applied to each weld. When using a chiller, steadier welding current can be produced and therefore a consistent amount of heat is applied to every weld. Welding tips last longer, and welded part production improves, all while ensuring project repeatability. In production environments with multiple welders or robotic welding systems, one central chiller can be used to manage all equipment. A general rule for sizing chillers is to plan for a 1-ton of chilling for every 100KVA of welder capacity. All of oumal welding process chillers feature a variable-speed compressor and condenser fan for higher efficiency, precision temperature control within 0.5°℃, reliability and quieter operation. They are available as portable units (1-30 tons) or as large-capacity packaged chillers (40, 50, or 60 tons). Modular chillers are available over 60 tons. All of our chillers can be used on new welding equipment, or be used to upgrade or replace existing welding chiller systems. Oumal has been manufacturing temperature control units and process chillers for over 15 years. Our team of knowledgeable engineers can help with any welding chiller solution. Our insightful sales and support staff are available to assist with application questions, as well as standard and custom product specifications that ensure successful installation, operation, and maintenance. A more accurate way of determining appropriate chiller size is by computing BTU using a standard formula that also accounts for the duty cycle. To calculate for resistance welding: BTU/hr = (welder KVA) x (duty cycle) x (0.85) x (0.6) x 3415 BTU/hr To calculate for resistance welding: BTU/hr = (welder KVA) x (duty cycle) x (Eff power supply) x (Eff heat collection) x 3415 Eff. power supply = the percentage of output to input power Eff. heat collection = the percentage of heat absorbed by chilling water (varies by approximately 50-70%) Duty cycle = weld time on/ time elapsed Our process chillers can easily be customized and used to fit any welding need, as a spot-welder cooler, TIG-weld...

Winery Glycol Chillers-industrial chillers suitable for wineries The chiller is a multifunctional refrigeration machine used to cool liquids (usually glycol/water mixtures). It circulates to adjust the temperature of many different processes: distillation tower coolers, heat exchangers, fermentation tanks, etc. The most important thing in your process when controlling temperature and time is that industrial chillers will provide a continuous supply of coolant for work. Why does my brewery need a chiller? Your cooler provides cooling liquid to condense the vapor in the distiller and cool the mashed potatoes from the high temperatures of the cooking process. Historically, water was used to cool the distiller-in some selected distillers, this method continues to this day. Because of their rapid cooling capacity and water-saving features, most people now turn to chillers. The chiller allows the glycol/water mixture to operate in a closed loop, which means there is no waste. In addition, the faster the syrup cools, the less likely it is for bacteria to grow. What should I pay attention to when buying a chiller? Brewery chiller Our 12-ton air-cooled chiller can handle a heat load of 142,800 BTU/hour or 41.85 kW. The wineries we work with usually use this model. First, make sure that the chiller to be installed has sufficient heat load. Also known as cooling capacity, thermal load is the rate at which the chiller cools the process fluid. We don't want you to know how much BTU/hr or kW you need to maintain (we will help you here), but not all chillers can withstand the extreme temperature fluctuations used in the distillation process. Quickly cooling 65°C mashed potatoes to 26°C before fermentation may cause pressure on an incorrectly sized cooler. How to choose the right chiller? Each winery we work with is unique and requires different production schedules, space requirements and future growth plans. Once you have determined the size of the distiller and masher, we can begin to help you design the winery cooling system. Knowing when your equipment is running will also play a big role. For example, as the winery grows, you may decide to increase production by adding night shifts – this will almost always require a larger chiller than you originally purchased. Discussing your future growth plans with a process cooling technician can help you save on long-term costs for the brewery while reducing potential pressure on the chiller. In a winery, your chiller has multiple processes that require its continuous support. Therefore, the ideal cooling process should be designed together with the rest of the distillation equipment and purchased at the same time as the distiller. Discuss your cooling chiller system needs with engineers who understand the distillation process is the key to choosing the right cooler, and we will customize the chiller for your company

Because the screw chiller, industrial chillers sometimes used in some flammable dust, gas or chemical fields. At this time, the chiller needs to be explosion-proof in the electric control, motor, fan and other places for safety.
