Seems to me HEAT is the destroyer !!put the compressor in a box with a small 2,500 BTU air conditioner , but you need to change the thermostat inside the unit to one that will go lower ( as in 38 degrees .) Most air units the thermostat only go's down to 50 degrees . the box could house ALL the components , air filters and such , fill hose on the outside . ALL this comes from Home brewing .Built a 5 x 10 walkin insulated cooler room with a 5000BTU AC , worked great .
