Low temperature circulator 
Model CCA-1112A • S
♦ Slim design for space-saving installation
CCA-1112A
◊ It has a slim design with a space-saving footprint of 205W × 405D mm.
◊ CCA-1112A and CCA-1112S are standard chillers with a cooling capacity of 500W (at liquid temperature of 20°C) and a discharge pressure of 0.04MPa. These chillers have a proven track record of being integrated into rotary evaporators, machine tools, analytical instruments, and more.
◊ For aqueous samples, one aspirator and one evaporator (either N-1300 or 1210B series: up to 1L sample flask) can be connected. For solvent-based samples, one solvent recovery unit and one evaporator (either N-1300 or 1210B series: up to 500mL sample flask) can be connected.
◊ The environmentally friendly natural refrigerant model CCA-1123A • S are also available.
♦ Designed with space efficiency and user-friendliness
As a space-saving model, it can be installed in tight spaces such as on, under, or beside laboratory bench.
Easy-to-use design down to the smallest detail. The filter is made of a material that will not deteriorate even if washed with water. It can be easily replaced by simply opening the louvers
The insulated hose connects easily by simply inserting it—no tools or clamps required. The direction of the circulation nozzle can be adjusted 360°, reducing strain on the tubing.
♦ External input • output terminals
By connecting the chiller CCA-1112A to the rotary evaporator N-1210B series with a dedicated communication cable (optional), it is possible to link with the evaporator (start • stop operation) without using the vacuum controller NVC-3000.
CCA-1112S is equipped with an alarm signal output terminal. Upon receiving the alarm signal, it can stop the connected device or activate a commercially available warning light.
♦ Cooling of heat-generating parts of industrial machinery, analytical and measuring instruments
CCA-1112S can be widely used for cooling heat-generating parts of industrial machinery and analytical and measuring instruments.

◊ Examples of custom orders
EYELA chillers are designed to accommodate the characteristics of the connected devices, their functions, system configurations, and various requirements associated with integration. We also produce customized models and special-specification products to meet specific needs.
| Remote control function | Remote control of chiller power, temperature control ON-OFF, and pumps. |
| Bypass line・Valve・Relief valve | It reduces the decrease in stirring efficiency within the reservoir caused by pressure loss at the circulation destination, as well as alleviates the load on the pump. |
| Circulation pressure control | The valve and pressure gauge are installed in the bypass line to adjust the circulation pressure. When a certain back pressure is detected, the relief valve activates. |
| Power cord extension | When extending the power cord for installations located far from the primary power source, ensure the proper gauge and length of the extension cord to avoid voltage drops or power issues. |
| Tip-over prevention countermeasure | Installation of earthquake-resistant auxiliary brackets and L-shaped brackets. |
