Unfired Water Heaters

Leslie Constantemp® heaters use a tightly-coiled circulating exchanger to transfer heat energy from the isolated steam flow to the desired liquid. These systems can take advantage of very low steam pressures and can deliver liquids at precisely defined temperatures. Available sizes include 15, 30, 45, 60, 75, 90, 105 and 120 GPM models with adjustable ranges from 105°F to 180°F.\ Learn More
