WARNING
WARNING
1For safety use
Do not touch cooling fin with bare
hands during maintenance operation.
The edgy fin may cut your hands.
Do not touch cooling fin with bare
hands.
-1 -
Leaving inflammable and combustible
solution out at room temperature or higher,
it (ethanol and etc.) may evaporate, catch
fire and explode. Ventilate well before use
and use care when handling these
solutions.
Use extreme caution when using
inflammable and combustible solution.

2-1 Use application
2-2 Specification
Do not remodel the product.
Make sure that it should not be used
out of intended use.
Remodeling and improper use may cause
electric shock or breakdown.
WARNING This is the cool water circulating machine to
cool down the liquid in the bath with using
cooling machine and circulate the liquid
externally by circulating pump, and to cool
down generating heat part of evaporator,
reaction bath and other devices.
Circulation to open system can be performed
when sealing up cover, which is one of the
options, is used.

Spec.

*1 The instrument does not incorporate heater.
Use antifreeze when using the heater at 5⁰C or less.
*2 Conditions
• Room temperature: 20⁰C • Water: 14 L
• Circulation amount: Maximum • Setting: 5 to 35⁰C
• Power source: AC200V 50/60Hz
• Heat load: Cooling capacity: smaller (approx. 90％)/ Cooling capacity: larger (approx. 110%)
• Cooling machine performs ON/OFF operation depending on use conditions (Room temperature,
load, type of secondary refrigerant and the condition of stirring in the bath) and the temperature may be
out of this range, because the cooling machine protection timer works.
• Cooling machine performs ON/OFF operation when preset temperature is from 4 to 10⁰C, and
the temperature may be from ±2 to ±5⁰C depending on use conditions (Room temperature, load, type
of secondary refrigerant and the condition of stirring in the bath), because cooling machine protection
timer works.
*3 Condition
• Room temperature: 20⁰C• Circulation flow: maximum • Power supply voltage: AC 200V 50Hz
• Cooling capacity is ±10％of indicated capacity.
• Cooling capacity varies depending on use condition such as room temperature, load, type of
secondary refrigerant and the condition of stirring in the bath.
*4 Condition
• Water temperature: 20⁰C
• Power supply voltage: AC 200V 50/60Hz
• Circulation capacity id ±10％of indicated capacity.
• Circulation capacity varies depending on the type of secondary refrigerant and etc.
*5 Alarm output is contact output (a-contact).
Contact capacity • AC 250V/DC 30V 3A Max.

* Circulation capability varies depending on the diameter of discharge nozzle, the
condition of piping, the type of secondary refrigerant and etc.
In case that the circulation is not sufficient, use high pressure pump HPP, which
is one of the options.
* When the circulation pump performs cutout operation, it may cause malfunction of
the pump. For this reason, use bypass valve in order to circulate during operation.
* Cooling capability change starts when the measured temperature
reaches at +4⁰C.
* Cooling capability varies depending on use conditions such as room
temperature, power supply voltage, type of secondary refrigerant, stirring
in the bath and etc.
