Cooling Capacity 250-3,500 W @+20 °C; Process Fluid Flow Rate 4 lpm @3.5 bar; Temperature Stability ≤±0.1 K; Coolant Temperature 10-35 °C Termotek’s piko series of recirculating chillers is a further development of the supplier’s successful P300 series. piko chillers are active cooling systems suitable for applications which require a particularly high degree of temperature stability of ±0.1 K. Being plug-in coolers, piko chillers are suitable for integration in a wide variety of systems. The chillers’ heights vary according to the power: sizes ranging from 3 to 12 RU (rack units) with a refrigeration capacity of 250 W to 3.5 kW are available as standard. While standard piko chillers operate on 230 VAC, the special version piko 24/48 VDC is designed for 24 or 48 V DC and can therefore be integrated in the low-voltage circuits of customers ex works. The service-proven cooling concept of the P300 series is continued in the piko, which also uses deionised water for the cooling medium as well. A new feature offered by the piko series is a special controller platform, providing the complete monitoring of the entire process, registering all relevant parameters in real-time and therefore guaranteeing extremely high levels of accuracy – also possible from any location if the optional remote mode is used. A new design feature contributes to the high operational reliability of the piko coolers: all components can be accessed from the front, which means that the unit no longer needs to be taken out of the mounting rack for maintenance work. Key Features: Size- and Service-optimized 19” Concept Temperature Control (Cooling / Heating) Cooling Capacity: 250 W to 3.5 kW (@+20 °C Water, +20°C Ambient) Loop Cooling Water Flow: +10 to +35 °C New Modular Controller Platform Extremely High Level of Temperature Stability: ≤0.1 K Particularly Low Maintenance High Level of Reliability Suitable for a Variety of Fluid Media Like Deionised Water or Water Containing Defined Additives Reduced Noise and Vibrations Energy-efficient and Space-saving Innovative Design Service-friendly Front Panel Access Flow Measurement and Monitoring Adjustable Water Bypass Valve Remote Start Via 24 VDC Signal Speed-controlled Fan 50 Hz/60 Hz Design 24/48 VDC Version for Low-voltage Circuits Available Refrigerant R134a RS 232/485 Interface Applications: Cooling of Systems Requiring a Particularly High Degree of Temperature Stability
