Heating / Cooling Circulator

Lab1st provides you with comprehensive temperature control equipment, which can be adjusted from -120℃ to 300℃.

Currently we provide 3 standard production lines: Refrigerated (Cooling) Circulators (DL series, DLH series), Heating Circulators (UC series, OBC series) , Heating and Cooling Circulators (DC series, HR series, HRV series). We also provide corresponding customized services, such as adding PLC control functions, etc.

PID temperature control process and accuracy can reach ±0.1°C

The liquid storage tank and circulation pipeline are made of 304 stainless steel with good corrosion resistance.

Multiple protection of overvoltage, delay, overcurrent, overheating, leakage, etc.

Microcomputer control, full digital display, easy to operate.

Heating Circulator

Lab1st provides 2 series Heating Circulators--UC  Series anf OBC Series to meet the different requirements.

  • Lab1st UC series is a hermetic heating circulator with a temperature range from room temperature to 200°C/300°C. The machine adopts electric heating mode, through the circulation pump output heat conduction fluid to heat the materials in the supporting reaction vessel. It is widely used in laboratory, pharmaceutical chemical industry, petrochemical industry and other high temperature environment.
      • Desktop design, compact structure
      • Open bath for internal / external applications High temperature design, reaching 300℃
      • High precision
  • Lab1st OBC series is a kind of heating bath circulator, with temperature ranges from RT~99°C or RT~180°C. It can provide heating fluid to jacketed reactors or other devices. Heat transfer fluid can be water or oil according to specific temperature requirements. It is widely used for drying, concentration, distillation, dipping in chemical reagents, dipping medicines and biological products.
      • Economical design, reliable quality
      • Open bath for internal / external applications
      • The circulation pump is powerful and suitable for use with reactors
      • Moderate accuracy

    Cooling Circulator

    Lab1st offers 2 series of Cooling Circulators--DLH series hermetic cooling circulator and DL series cooling bath circulator to meet the different requirements.

    • Lab1st DLH series chillers are Hermetic Cooling Circulators with operating temperatures ranging from -20C/-30C/-40C/-80C/-120C to room temperature. The liquid storage tank adopts full hermetic design, which is not easy to absorb moisture at low temperature and prolongs the service life . And the system has an exhaust port that can successfully complete the thermal fluid filling. Moreover, it's with microcomputer control and full digital display, easy to operate. It also with high and low voltage protection, overload protection, over current protection, grounding protection and other protection functions. Note: The ultimate temperature of the chiller is affected by the load, heat preservation effect and the environment of the application site.
        • Prevent steam from condensing in the coolant
        • Design of plate heat exchanger and small volume liquid tank to achieve rapid refrigeration
        • Optional temperature range and cooling capacity
    • Lab1st DL series Cooling Bath Circulator has an operating temperature ranging from -20C/-30C/-40C to room temperature. With large capacity open bath and external circulation system, it can be used as a separate chilling tank, and can also provide low temperature coolant externally. The refrigerant outlet is equipped with a pressure gauge to display the refrigerant pressure at the outlet. The system is microcomputer control, full digital display and easy to operate. It also with high and low voltage protection, overload protection, over current protection, grounding protection and other protection functions.
        • Simple design, economical and practical
        • Open bath for internal / external applications
        • Suitable for occasions with low temperature control accuracy, such as the condensation tube of a rotary evaporator

    Heating & Cooling Circulator

    Lab1st provides 3 series Heating Cooling circulators--DC series, HR series and HRV series heating cooling circulators to meet the different requirements.

    • Lab1st DC series heating cooling circulator is an open table type circulator with compact structure and small footprint, which the temperature range is -5℃ - 95℃. Its realize inside and outside circulation, achieve "constant temperature" in the liquid tank and the compressor can be started at high temperature. Intelligent control system, rapid temperature rise, stable temperature make it easy to operate. 
      • Desktop design, compact structure
      • Open bath for internal / external applications
      • High precision
      • The compressor can be turned on to quickly cool down at high temperatures
    • Our HRV series hermetic heating cooling circulators have a working range of -100°C to 200°C, and are widely used in pharmaceutical, chemical, biological and other industries to provide heat and cold sources. The machine adopts a fully enclosed pipeline design and is equipped with a high-efficiency plate heat exchanger, which reduces the demand for heat transfer fluid and improves the heat utilization rate of the system to achieve rapid temperature rise and fall. The heat transfer medium is in a hermetic system with an expansion tank. The heat transfer medium in the expansion tank does not participate in the circulation. Whether it is high temperature or low temperature, the expansion tank is kept at 60°C, which effectively reduces the risk of the heat transfer medium absorbing moisture and volatilizing during operation.
      • Wide operating temperature range, with heating and cooling functions
      • PT100 temperature sensor, overvoltage, delay, overcurrent, overheating, leakage, protector, etc.
      • Higher power devices can be customized
      • Can be upgraded to PLC remote control
