The MACRO SCIENTIFIC WORKS PVT LTD REFRIGERATED CIRCULATING LIQUID / WATER BATH “MAC” MSW-270(R) is a precision laboratory temperature control system designed for applications that require stable, repeatable, and efficient cooling or heating of circulating fluids. Built with an SS-304 stainless steel inner bath chamber and lid, it offers excellent corrosion resistance, dependable hygiene, and long service life in demanding lab environments. The powder-coated CRC sheet outer body provides a durable protective finish, while the high-grade PUF insulation between the inner and outer chambers helps minimize thermal losses and improve energy efficiency. This refrigerated circulating bath is engineered for enhanced thermal performance with high condensation efficiency, a hermetically sealed compressor, and environment-friendly CFC-free refrigerants. Its microprocessor-based autotune PID temperature controller enables tighter temperature regulation, making it suitable for processes that depend on consistent bath temperatures and low fluctuation. The internal circulation system improves temperature stability and uniformity across the bath, supporting more accurate results in analytical, research, and industrial lab workflows. The unit features a temperature display resolution of 0.1°C, giving users precise visibility into operating conditions. A powerful stirring circulation pump with 15 Lpm capacity at zero head ensures effective fluid movement for uniform temperature distribution. The model supports an adjustable temperature range, with this configuration listed as ambient to -5°C at zero delta (ambient 25°C). The bath is designed for approximately 3 to 4 litres of liquid fill capacity with a gross tank capacity of 6 litres. This refrigerated circulating liquid bath also helps reduce tap water consumption, lowering operating costs and minimizing wastewater generation. It is suitable for laboratories and facilities that need controlled chilled water circulation, temperature stabilization, and efficient cooling performance. For best operation, water should not be used below 5°C; ethanol is recommended below 5°C, and silicone oils or similar media should be used above 90°C. With its combination of precision control, robust build quality, and efficient refrigeration, the MAC MSW-270(R) is a reliable choice for professional lab temperature management.
