Features

Air-cooled, precision temperature control, and long
selling chillers for open circuits. Renewal improves
detailed usability.

CL series is an air-cooled, high-precision open-circuit chiller (constant temperature water circulation system).
It is mainly used for temperature control of constant temperature water baths, and is ideal for circulation to temperature control water baths required for quality tests, etc.
This series is a long-selling product that has been refined for over 35 years.
CL-81/151/601 is reliable as in the previous model and their weight were reduced by 3kg/7kg/1kg each. In addition, the drain cock was repositioned from the rear side of the unit to the front side for better usability.

Temperature recording and safety device output are
possible, and optional program control are possible

The CL series allows for temperature recording and safety device operation signal output, and external temperature sensors can be used.
Also, by connecting to a program setting device (sold separately), temperature and time program control are possible.

Optional port tank allows for circulation in closed circuits

In addition to circulation to the water bath as a chiller for the open circuit, it can also circulate to equipment (= closed-circuit circulation) using a separately sold port tank.
Even for the one targets with high piping resistance such as rotary evaporators, circulation can be easily started with the
built-in priming pump.

(*1)Make sure there is no condensation on the unit
(*2)Use a low-temperature heating medium when using the product at a temperature of 7°C or less. (Contact us for details.) Pure water and distilled water cannot be used.
(*3)The temperature accuracy is when the inside of the water bath is sufficiently stirred. The temperature accuracy and power consumption vary depending on various conditions, such as the set temperature, environmental temperature, water bath capacity, and stirring state. We recommend using a lid for the water bath. The specifications of this unit include the performance values according to our specified measurement method
(*4)Temperature control accuracy at 25.0°C setting is ~ ±0.1°C using environmental temperature 25°C/clean water 5L/heat insulation water bath/lid
(*5)Capacity when the environmental temperature is 25°C and the circulating fluid is +10°C, and 50Hz. The cooling capacity will be reduced in environments exceeding 30°C.
