On a military base in east-central Alaska — where the average winter temperature is 16° F with lows that fall well below minus 50° at times — dependable, low-maintenance winter heating systems are critical for the active-duty military families and Department of Defense civilians who live on the military post.
The company that owns and manages the on-base military housing units was faced with a challenge when renovating the base housing mechanical systems. The original heating system circulators were outdated and inefficient. In addition, many of the older circulators were the three-piece oil-lubricated type with mechanical seals that required yearly maintenance and costly part replacements.
