LTC4 Refrigerated Circulating Baths

Product catalog summary

Overview: The document provides comprehensive details on the Optima™ range of refrigerated and heating circulating baths and recirculating chillers by Grant Instruments. These systems are designed for precision cooling in low-temperature applications, available in both open-loop and closed-loop formats. They are recognized for their quality, reliability, and compact design, and come with a 3-year warranty.

Specifications: The Optima™ range includes 18 models with varying thermostats and refrigeration units, operating between -47°C and 100°C. Recommended liquids include silicone oil, water-antifreeze mixtures, and water, depending on the temperature range.

Model Showcase: The TC120-R2 model is noted for its versatility, with a temperature range of -25°C to 100°C and stability of ±0.1°C. It features a digital thermostat, a powerful integral pump, and user-friendly design elements.

Factors to Consider: Key considerations when selecting a system include sample immersion needs, cooling power requirements, cool-down time, external device temperature control, and additional features like temperature ramping and programmable controls.

Technical Specifications: Detailed technical specifications are provided for thermostats and refrigeration units, including stability, uniformity, setting resolution, and communication interfaces. The performance of optional high-pressure pumps and their impact on cooling power is also covered.

Models and Accessories: Various models and kits are available, with options for external probes, remote switching devices, and vertical turbine pumps. Specifications for each model include capacity, dimensions, and weight.

Recirculating Chillers: The RC series offers robust cooling solutions for industrial and scientific applications, with temperature ranges from -10°C to 60°C or -5°C to 60°C. They provide a cost-effective alternative to mains water cooling, featuring digital controllers for precise temperature settings.

Key Features: The RC series includes automatic optimization with the UL TUNE facility, mobility with lockable wheels, and built-in safety mechanisms. Four models are available, with three functioning as recirculating chillers/heaters and one as a dedicated chiller (RC3000G).

Applications: These systems are used in electronics for cooling etch baths and glass coating, in industry for print head cooling and calibration system probes, in academia for cooling lab equipment, and in research for seed research and cooling scientific units.

Specifications: The temperature range is ambient 20°C, with most models ranging from -5 to 60°C. Stability varies from ±0.25°C to ±0.5°C, and cooling power varies by model, with the RC3000G offering up to 3000W at 20°C. Heater power is up to 1.5 kW, except for the RC3000G. Maximum liquid flow rate is 15 L/min with a pump head pressure of 1.6 bar at 1 L/min. Reservoir capacity ranges from 1.1 to 2.5 liters.

Accessories: Available accessories include the RC BYP bypass, RC PR pressure gauge, PRES priming reservoir, external probe for remote sensing, and rear connecting fittings for various hose sizes.

Dimensions and Weight: The RC350G and RC400G weigh 42 kg with dimensions of 510 mm height, 600 mm depth, and 370 mm width. The RC1400G weighs 53 kg with dimensions of 590 mm height, 630 mm depth, and 380 mm width. The RC3000G weighs 88 kg with dimensions of 640 mm height, 840 mm depth, and 490 mm width.

Factors to consider when choosing your system n Do you need to immerse samples within a tank? Consider the working area required. The table on p. 2.4 shows the dimensions of the top opening and the min/max liquid depths n Cooling power required at a given temperature For example, if your operating temperature is 0°C, and you need 500 W cooling power, you will need the R4 (or R5) refrigeration unit with any of the controllers. Alternatively to calculate the power required use the following formula: W= n Cool-down time required to reach that temperature W = average cooling power V = total system...
