I have a mint condition Melcor liquid Chiller, model MLA270DH-2-115 which has 270 watts cooling capacity and an accuracy of plus or minus 0.25 degrees Celsius. the liquid reservoir holds 450 mL and the flow 0.5 gallons per minute or 1.9 litres /minute. Retail cost of this solid state TEC cooling unit is $2,730 US.
Asking price $500 US minimum and again I'm up for negotiation on cash trade combinations if you have something of interest to me.
