The Nextreme Recirculating Chiller Platform from Laird Thermal Systems offers reliable and precise temperature control of 3D printing systems used in additive manufacturing applications in a range of industries. The Platform can control the temperature of all sensitive electronics within 3D printing systems, including the power source, the laser or electron beam optics and the thermal print head. In addition, a chiller can be used to quickly cool smaller and/or highly detailed 3D printed objects to preserve fine design details.
To ensure high performance and long-life operation of 3D printing systems, laser and electron beam optics must be sufficiently cooled and maintained at a stable operating temperature. Precise cooling is also needed to help control the viscosity of the liquid powder as it is dispensed onto the surface of the thermal print head to preserve the deign details and quality of the printed part.
与其他冷却技术相比，基于压缩机的制冷系统提供了更高的性能系数。通过使用高性能变速电机，与传统的基于压缩机的系统相比，Nextreme Chiller静静地运行，能耗高达50％。通过使用环保R513A制冷剂，与传统的氢氟烃（HFC）制冷剂相比，Nextreme Chiller通过全球变暖潜力（GWP）提供类似的性能。
“3D印刷机从Nextreme Chiller在设定点温度的±0.1°C中实现温度稳定性的能力很大，”Laird热系统的液体冷却系统产品总监Greg Ducharme说。“Nextreme再循环冷却器系统可以加热和冷却流体以保持热设定点，提供更大的灵活性和减少实施单独加热元件的需要。”
For maximum uptime, the Nextreme Chiller features the optional hot swappable 5-micron water filter for filtering particulates from the coolant circuit, which means that the unit can continue operating even during maintenance. With no moving parts, an optical fluid level sensor offers higher reliability and increased uptime when compared to chillers that use mechanical float switches. The programmable alarm alerts the user when fluid level drops below acceptable operating conditions. To prevent damage to equipment in high pressure operating conditions, the chiller senses the supply fluid pressure and will alert users when low- or high-pressure limits have been exceeded.
The LCD touchscreen display allows the user to easily control temperature setpoints, flow and alarm settings and coolant type while coolant level can be monitored via the indicator window on the front panel.
Nextreme Chiller系列有三种标准型号，1800 W，2800 W和5000 W.所有这些型号都可以配置为满足特定的应用要求。
