Arrived at KIG in August 2016 was this super clean .5 ton Cold Shot Air Cooled Chiller. Low profile design, outdoor rated, 1.5 hp pump, 208/230 volt three phase power. All these units had brand new controls added by a certified technician. If running straight water and industrial temps (about 55°F), unit will achieve about 12,000 btu/hr. For fluid temps in the 40° to 50° range, expect about 40 tons of capacity.
KIG has refurbished, tested, and provided dozens of this series and style chiller with outstanding track records in the field. Unit has dual fans, a brazed plate exchanger within the polymer tank, and a 2 hp process pump. In addition to the standard temperature range of 48°F to 70°F, KIG can configure these units for 28°F Glycol temperatures also (de-rating applies). This is an indoor chiller; it must be in an ambient environment of 55°F to 95°F. We ran and tested this unit thoroughly in our 13,000 square-foot chiller facility prior to shipping.
Because an industrial chiller works on a continuous cycle, this low-pressure liquid is then transferred back to the evaporator where the whole cycle will repeat itself. Delta T Systems is introducing a completely new single and dual zone temperature control heater/chiller combo package. GCI’s versatile family of DS Series Icewagon™ chillers is engineered for general purpose applications, where performance, cost, and operating flexibility are key requirements. Both air and water condensing models are available, and the series comes with compressors sized from 1 to 12 hp to meet a broad range of industrial cooling needs. Rugged yet compact, the DS Series incorporates many of the features found on larger, more expensive chillers.
Choose from air-cooled and water-cooled comfort cooling chillers, each offering a unique set of advantages to consider for your application and budget. 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.
Comparing the same 200-ton chiller plant, the water-cooled plant would cost roughly $80,000 more to build. The water-cooled plant would save the owner around $53,040 per year in energy costs, which in turn would mean it would take 1½ years to get a return on the investment. As stated above, 1 ton of cooling is equal to 12,000 Btu, so a 200-ton chilled water plant has 2.4 million Btu. The most common chilled water delta T is 12°F; in the equation, the system requires a chilled water flow of 400 gpm, which equates to 2 gpm per ton. Btu is the cooling or heating load; 1 ton of cooling is equal to 12,000 Btu. There also should be a decoupler between the primary and secondary loop.
In this blog, we perform a chiller efficiency comparison to help you determine which type of chiller is right for your HVAC system and your overall commercial facility. The vapor-compression industrial refrigeration system uses a circulating liquid refrigerant as the medium which absorbs and removes heat from the space to be cooled and subsequently rejects that heat elsewhere. Chillers are also often used for industrial or medical applications.
