Recirculating Cooler
Operating manual
1.Intended use
JULABO recirculating coolers have been designed to control the temperature of specific fluids in a bath tank. The units feature pump connections for temperature control of external systems (loop circuit).
JULABO recirculating coolers are not suitable for direct temperature control of foods, semi-luxury foods and tobacco, or pharmaceutical and medical products. Direct temperature control means unprotected contact of the object with the bath medium (bath fluid).
1.1.Description
PID2 |
ATC3
RS232
SMART
PUMP
The recirculating coolers are operated via the splash-proof keypad. The implemented microprocessor technology allows to set and to store different values that can be indicated on the MULTI-DISPLAY (LED). Three menu keys facilitate adjusting setpoints, warning and safety functions and menu functions.
The PID temperature control adapts the heat supplied to the thermal requirements of the bath.
Absolute Temperature Calibration (ATC3) provides a high temperature stability in the bath. With the 3-point calibration an offset is adjusted at three temperatures to ensure an accurate temperature pattern at the selected spot in the bath over the full temperature range.
Electrical connections:
The serial interface RS232 allows modern process technology without additional interface.
The excess temperature protection conforming to IEC 61010-2-010 is a safety installation independent from the control circuit. This protection can be indicated and set on the MULTI-DISPLAY (LED).
The early warning system for low level signals that bath fluid needs to be refilled before the low level protection conforming to IEC 61010-2-010 causes a complete shut-down of the main functional elements.
The pump capacity (electronically adjustable via the motor speed) enables to adapt to varying conditions for internal and external temperature applications.
2.Operator responsibility – Safety instructions
The products of JULABO ensure safe operation when installed, operated, and maintained according to common safety regulations. This section explains the potential dangers that may arise when operating the circulator and also specifies the most important safety precautions to preclude these dangers as far as possible.
The operator is responsible for the qualification of the personnel operating the units.
5
Operator responsibility – Safety instructions
The personnel operating the units should be regularly instructed about the dangers involved with their job activities as well as measures to avert these dangers.
Make sure all persons tasked with operating, installing, and maintaining the unit have read and understand the safety information and operating instructions.
When using hazardous materials or materials that could become hazardous, the circulator may be operated only by persons who are absolutely familiar with these materials and the circulator. These persons must be fully aware of possible risks.
If you have any questions concerning the operation of your unit or the information in this manual, please contact us!

Safety instructions for the operator:
Avoid strikes to the housing, vibrations, damage to the operating-element panel (keypad, display), and contamination.
Make sure the product is checked for proper condition regularly (depending on the conditions of use). Regularly check (at least every 2 years) the proper condition of the mandatory, warning, prohibition and safety labels.
Make sure that the mains power supply has low impedance to avoid any negative effects on the instruments being operated on the same mains.
This unit is designed for operation in a controlled electromagnetic environment. This means that transmitting devices (e.g., cellular phones) should not be used in the immediate vicinity.
Magnetic radiation may affect other devices with components sensitive to magnetic fields (e.g., monitors). We recommend maintaining a minimum distance of 1 m.
Permissible ambient temperature: max. 40 °C, min. 5 °C.
Permissible relative humidity: 50% (40 °C).
Do not store the unit in an aggressive atmosphere. Protect the unit from contamination.
Do not expose the unit to sunlight.
Appropriate operation
Only qualified personnel is authorized to configure, install, maintain, or repair the circulator.
Persons who operate the circulator must be trained in the particular tasks by qualified personnel. The summarized user guidance (short manual) and the specification table with information on individual parameters are sufficient for this.
Use
The bath can be filled with flammable materials. Fire hazard!
There might be chemical dangers depending on the bath medium used.
Observe all warnings for the used materials (bath fluids) and the respective instructions (safety data sheets).
Insufficient ventilation may result in the formation of explosive mixtures. Only use the unit in well ventilated areas.
Only use recommended materials (bath fluids). Only use non-acid and non corroding materials.
6
Recirculating Cooler
When using hazardous materials or materials that could become hazardous, the operator must affix the enclosed safety labels (1 + 2) to the front of the unit so they are highly visible:
1 |
Warning label W00: Colors: yellow, black |
|
|
Danger area. Attention! Observe instructions. |
|
|
(operating manual, safety data sheet) |
|
|
|
|
2 |
Mandatory label M018: |
Colors: blue, white |
Carefully read the user information prior to beginning operation.
Scope: EU
or
2 Semi S1-0701 Table A1-2 #9
Carefully read the user information prior to beginning operation.
Scope: USA, NAFTA
Particular care and attention is necessary because of the wide operating range.
There are thermal dangers: Burn, scald, hot steam, hot parts and surfaces that can be touched. Warning label W26: Colors: yellow, black
Hot surface warning.
(The label is put on by JULABO)
Observe the instructions in the manuals for instruments of a different make that you connect to the circulator, particularly the corresponding safety instructions. Also observe the pin assignment of plugs and technical specifications of the products.
2.1.Disposal
The recirculating cooler contains a back-up battery that supplies voltage to the memory chips when the unit is switched off. Do not dispose of the battery with household waste!
Depending on battery regulations in your country, you may be obligated to return used or defective batteries to collection sites.
The product may be used with oil as bath fluid. These oils fully or partially consist of mineral oil or synthetic oil. For disposal, follow the instructions in the material safety data sheets.
This unit contains the refrigerant R404A, which at this time is not considered harmful to the ozone layer. However, over the long operating period of the unit, disposal rules may change. Therefore, only qualified personnel should handle the disposal.
Valid in EU countries
See the current official journal of the European Union – WEEE directive. Directive of the European Parliament and of the Council on waste electrical and electronic equipment (WEEE).
This directive requires electrical and electronic equipment marked with a crossedout trash can to be disposed of separately in an environmentally friendly manner. Contact an authorized waste management company in your country.
Disposal with household waste (unsorted waste) or similar collections of municipal waste is not permitted!

Risk of oil leaking from the refrigeration system (compressor) of the recirculating cooler into the cooling water in case of a fault in the cooling water circuit!
Observe the laws and regulations of the water distribution company valid in the location where the unit is operated.
Notice:
Danger of corrosion of heat exchanger due to unsuitable quality of cooling water.
Due to its high content of lime, hard water is not suitable for cooling and causes scale in the heat exchanger.
Ferrous water or water containing ferrous particles will cause formation of rust even in heat exchangers made of stainless steel.
Chlorinated water will cause pitting corrosion in heat exchangers made of stainless steel.
Due to their corrosive characteristics, distilled water and deionized water are unsuitable and will cause corrosion of the bath.
Due to its corrosive characteristics, sea water is not suitable.
Due to its microbiological (bacterial) components, which settle in the heat exchanger, untreated and unpurified river water and water from cooling towers is unsuitable.
Avoid particulate matter in cooling water.
Avoid putrid water.
