The JSR JSRC series is a cooled-heated circulating water bath designed to operate over a wide temperature range from -20°C to 120°C. It offers models with volume options of 7, 11, 22, and 30 liters to meet diverse laboratory requirements. The bath is applicable for sample temperature stabilization, viscometer connection, or applications requiring external circulation.

The unit features a microprocessor-based PID controller and Class A Pt-100 sensor, delivering ±0.1°C accuracy. With a CFC-free air-cooled compressor and direct immersion heating element, it operates stably across the wide temperature range. The stainless steel submersible pump enables both internal and external circulation modes; connections via ∅9 mm hose fittings allow easy integration with external circuits.

The bath tank is manufactured from electropolished seamless 304 stainless steel, the lid from bright 304 stainless steel, and the chassis from epoxy powder-coated steel. Safety features including over-temperature cut-off, overcurrent protection, and low water level cut-off are standard. Power input: 220V ±10%, 50/60Hz, single phase.
