Description   Aqua Logic¡¯s Delta Star in line TITANIUM water chillers were first introduced to the aquatic market in 1989. Known for their quality craftsmanship and exceptional performance they quickly became the industry standard that all other brands have tried to achieve. For over 15 years this same attention to quality and performance still goes into every unit we manufacture. TITANIUM is the only heat exchanger material proven to be 100% fish and coral safe in saltwater systems. The Delta Star is built with an oversized helical titanium coil in the heat exchanger to maximize BTU transfer efficiency. The quite, internal, spring mounted hermetic motor/compressor provides years of reliable service. Their low profile and compact design allows for easy placement in tight places. Each unit comes with a Black ABS plastic cover. A pump is required with Delta Star chillers to move water thru the heat exchanger. Please see section below for recommended pump selection chart. Applications: Aqua Logic manufactures chillers for a wide variety of applications. Since ¡°one chiller does not fit all¡± chillers are designed and build for specific uses. For example Marine Reef Tanks are typically maintained at a constant temperature of 76¢ª - 78¢ªF while bait tanks are cooler, around 50¢ª - 55¢ªF. Research applications may require the chiller to maintain a wide range of temperatures as low as 35¢ªF during some portion of the experiment and as high as 80¢ªF during other times. Each of the scenarios requires the chiller to be manufactured with different parts so they operate at their maximum efficiency. Our ¡°standard¡± units (1/5-1/2 hp) are for applications where the temperature to be maintained is in the range of 65¢ª - 80¢ªF such as reef tanks and warm water fish exhibits. The cool water units (option A with coldwater cap tube) are designed for a temperature range of 50¢ª - 65¢ªF for bait fish and temperate fish exhibits. For those applications where the unit will need to maintain a very cold temperature, such as lobster tanks, cold water fish exhibits or research applications then our Option B with TXV would be required. Our Standard and Option A units are manufactured with a capillary tube of a size and length that allows a fixed amount of refrigerant to enter the titanium coil of the heat exchanger. This amount of refrigerant does not need to change since the water temperature being maintained remains relatively constant. These units are less expensive then the Option B units. Option B chillers have a thermal expansion valve that constantly regulates the amount of refrigerant going to the heat exchanger based on the temperature of the water that it needs to maintain. Colder water requires more refrigerant flow and warmer water requires less. All our Delta Star chillers 3/4hp and larger chillers come with the option B feature. You need to keep the above in mind when ordering your chiller. If you need a chiller for your lobster tank the chiller from aquarium store, catalog, or online retailer may not work for you. If you have any questions or not sure which chiller is right for you contact our office for help with your specific application.
