Sumitomo Cryogenics HC-4E Indoor Water-Cooled Compressor
We are selling this unit as is. The extent of our testing was removing the front panel to attach a power cord, plugging in, flipping the green main power switch, and then lifting the black power switch. The unit turns on, makes a constant, steady whirring sound, and the exterior starts to get cold. The pressure gauge is cracked (as you can see in the pictures) and does not change or do anything when the unit is powered on. We are unable to do any further testing. The power cord was previously removed before it came into our care. We can ship with the cable we used for testing this item if you are interested.
