What do I like about summer? Walking out of work when it's 90 F (32C) and getting chilled by the cold, LOL. With 5 2000 L water vessels heating at 155 C, 15 steam molding presses which all leak 4 bar steam out the sides every 2 minutes, and 6 extrusion lines giving off 440 F heat, the general plant climate is usually around 115 F (46 C) at about 95% humidity during midsummer. If you hold your breath, you're ok just standing. Take a breath and that's too much work, you are immediately soaked in sweat that it looks like you just jumped out of the swimming pool with your cloths on. We have a parts oven about 50x60 foot room that runs 135 F (57 C). With the humidity out on the manufacturing floor, you don't feel much of a difference walking in and out of the oven.
