In addition to extra capacity, new manufacturing equipment generates lots of extra heat. So our latest equipment purchase this year goes on the roof! On a bluebird day in Minnesota our HVAC contractor is installing a new 20 ton Lennox Strategos rooftop unit. According to the folks from Lennox, the Strategos is the most energy efficient rooftop unit in the industry. What's important to Lowell is that the added HVAC capacity helps maintain a constant temperature on our manufacturing floor and that's critical to machining conforming parts.
