Lauda - Ultracool UC14 Chiller (4.9kw @ -20°C) Rotary Evaporator Chiller

Energy-efficient process circulation chillers from −20 to 35 °C for laboratory and industrial applications. Great chiller for rotary evaporator, such as our 50 Liter Rotovap Kit.



This Goldleaf exclusive special model Ultracool chiller is perfect for low temperature and high cooling power laboratory equipment. We recommend this chiller for our 50L rotary evaporators and 50-150L reactors. Compared to other manufactures this model has plenty of power and is a great price.

Developed with a focus on energy efficiency, the new LAUDA Ultracool circulation chillers make it possible to reduce energy costs by up to 50% vs older built chillers.

The LAUDA Ultracool chillers can be conveniently monitored and controlled from a distance – via a connected remote control or the integrated web server. This allows convenient operation via mobile devices such as tablets or smartphones, and the relevant data can be stored in the LAUDA Cloud via an internet connection as an option.
