P300 Recirculating Chillers

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.

Two recirculating chillers in one cabinet, up to 900 W cooling capacity, 24 V DC power supply The DmRC-C-900-24-KIT is a development kit suitable for applications requiring high water cooling performance in the smallest of spaces for water coolers. Based on miniature compressors, this "mini Recirculating Chiller" development kit provides two independent water cooling systems in a 19-inch rackmount insert, which can provide a combined maximum cooling capacity of 900 W. With this double chiller concept, DmRC-C-900-24-KIT can cool two heat loads independently of each other – the target temperatures for each of the two heat loads can be set individually. The compressors’ BLDC motors are speed controlled and offer low vibration and low noise throughout the speed range. Since the water circuit is pressurized, DmRC-C-900-24-KIT manages with very small tanks (2 x 275 ml) – without the risk of cavitation in the smoothly operating centrifugal pumps. Overpressure on the cooling system also prevents the ingress of bacteria and oxygen and thus extends the maintenance intervals. An electric air pump generates the pressure on the two water circuits and is also used for automatic complete filling and emptying of the cooling water circuits, simplifying the maintenance of the system. For customer requirements that cannot be covered by the DmRC-C-900-24-KIT, our thermal management specialists at AMS Technologies are happy to develop a completely tailor-made solution and offer all services from development through to series production. Specifications: Power Supply: <700 W (max. 29 A @ 24 V DC) Cooling Capacity (approximately): 900 W (2 x 450 W, TWATER +25 °C, TAMBIENT +25 °C) Temperature Range: ± 1 K (over-/undershoot at 250 W load ON/OFF), ± 0.2 K (continuous operation) Hydraulic Parameters: flow rate 1 lpm to 5.5 lpm @ 1 bar to 0.2 bar pressure drop at heat load Cabinet: rack-mount, 19”, aluminium housing Weight: 20 kg (Dry Weight: 19 kg) Dimensions (WxHxD): 440 mm x 220 mm x 350 mm (main body, without flanges)

High performance in a space-saving, mobile housing – this has proved to be a tried-and-trusted combination over many years in all fields of laser cooling, including optical assemblies, in laboratories, in the printing industry and on machine tools and for HSC milling. The practical arrangement of all the components in the compact housing means not only low maintenance requirements but low vibrations and noise emissions too. The P800 recirculating chillers are available for power ranges from 1 to 15 kW. P800 chillers provide active cooling and therefore contain a refrigeration circuit with a compressor and a heat exchanger for a variety of media. Both the refrigeration circuit and the cold water temperature are monitored and controlled by a central control system. The cold water is reliably fed to where it is required by a pump. An optional particle filter in the cold water outlet keeps the circuit clean, and a flow sensor for the return flow guarantees the required stable operation. The waste heat is either emitted to the environment via speed-controlled fans or transferred to a central water circuit via heat exchangers, so that the waste heat can be used, for example, for preheating the process water.
