Question 17

Good AfternoonI have two questions for the USA Lab -40Â°C to 200Â°C 6L Heater Chiller UHC-10/4 equipment:1. Is that chiller appropriate to connect with some kind of heat exchanger in close loop (e. g. cold plate), to maintain temperature of this cold plate at -40 Â°C (when stored in some kind of uninsulated box). 2. Is the refrigerating wattage equal to 1.9kW also at -40 Â°C level? I would like to maintain the surface of cold plate (which is connected to the chiller) at -40 Â°C, while on this cold plate lies the sample which generate heat about 450 W.Best RegardsIwona Herbik View answer
