Footprint and Operating Requirements

How much space does the ColdBlock Digestion System occupy in the lab?

The ColdBlock Digestion System is designed so that the digester operates within a standard fume hood, the controller sits on bench space and is connected via cable and the chiller sits on the floor connected by hoses. The digester has a footprint of approximately 9.25” W x 23.5” L x 11” H and a weight of 35lbs. The controller has a footprint of approximately 8” W x 24” L x 24” H and weighs approximately 40 lbs. The chiller has an approximate footprint of 15” W x 26” L x 21.8” H and an approximate weight of 180lbs.

What are the power and ventilation requirements? 

The ColdBlock digestion system requires a single-phase connection to 30 A, 208-240 V circuit with NEMA L6-30 outlet.

The fume hood should have a draw of at least 400 cu ft./min (0.03 m3/min).
