I'm guessing you are talking about the low point drains. You can try putting some electric heat tape on the drains. You may try putting some other form of heat there even if it's a small space heater or a lamp. Just make sure if the water starts to drain/flow you don't have anything there that would cause an electrocution hazard. You may need to put a temporary boundary (think a box) around the drains to keep the heat in while doing this. What I've done in the past is drain the tanks before or while I'm leaving and driving home. And then leave the caps off until I'm home and then blow out the lines. Good luck.
