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.

Configuration

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.

-4 -

* 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.
