Manufacturer's Description

Advanced general purpose circulating water baths offer a range of accessories to suit your specific laboratory or process application. High-strength cabinet construction with 304 stainless steel interior tanks withstand the most critical applications in demanding laboratory environments. Circulating models are available in heated only versions, temperature range 5°C above ambient to +100°C, or combined heated/refrigerated models for operation from 0° C to +100°C.

General Features:

  • Choose from four popular cabinet sizes
  • Temperature range from 5°C above ambient to +100°C, uniformity ±0.1°C; refrigerated model rated at 0°C to +100°C, ±0.1°C
  • Microprocessor with RTD probe provides simple, accurate and repeatable temperature control while optimizing control parameters during operation
  • Single stage, centrifugal pump with independent supply/return ports for maximum circulation
  • Reversible stainless steel rack allows for optional reduction of working depth by 2" (50mm) Built to UL and CUL criteria for safety and performance
  • Includes 10± power cord with plug

Microprocessor Controller:

  • Digital temperature display, simultaneously shows set point and actual water temperature
  • Recessed control module protects against dirt and moisture
  • RS-485 communications port is available as an option

Dual Independent Over Temperature Safety System:

  • Adjustable high limit control prevents critical process overtemp conditions at any point over the bath operating range, protecting the bath and its load; interrupts heat, flashes visual warning and automatically resets when temperature returns to normal
  • Fixed over temperature safety, factory set 105°C, shuts off bath power; push button manual reset

Cabinet and Tank Construction:

  • Integrated industrial strength pump for internal circulation maintains precise temperature uniformity throughout the liquid medium
  • Rounded corners for better water circulation, improved uniformity and easier cleaning; includes a built-in drain with on/off valve
  • Moisture-proof blanketed fiberglass insulation surrounding water chamber improves temperature stability and energy efficiency
  • 304 stainless steel construction resists chemicals, simplifies cleaning
  • Long-life heating elements for quick response to controller
  • Protective non-skid rubber feet protect the lab bench
  • Attractive front panel bezel for easy cleaning
  • Mounting clip for immersion glass thermometer; thermometer sold separately

Refrigerated Model:

  • Refrigeration system allows accurate control at temperatures near or below ambient conditions
  • Quiet-running, hermetically sealed refrigeration system
  • High volume heat removal capacity rated at 3000 BTU/Hr at 27°C (nominal)
  • Ideal for use with 60%/40% ethylene glycol/water mixture to prevent icing at temperatures below 10°C
  • Independent ON/OFF switch for refrigeration system; system can be switched OFF for operation above ambient temperatures

Multi-Purpose Circulating Water Baths (UL and CUL Listed):

  • Temperature Range: 5°C above ambient to +100°C, uniformity ±0.1°C; maximum temperature dependent on altitude and load.
