Leslie Constantemp Feedforward Steam Water Heaters

Brand: Armstrong International

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.

Leslie Constantemp steam heaters are available in Inlet pressure ranges: 2-15 psig. Heating is instant on demand with capacities up to 7,200 gallons per hour.

Temperature variation is a maximum of ±3°F. The standard coil material is copper but Admiralty and cupro-nickel coils are available as special-service options.

The heart of the Leslie Constantemp steam water heater is the feedforward blending device.

The hot and cold water blend ratio is accurately proportioned to maintain the set temperature for all flow demands.

Water is blended instantly; automatically; with virtually no lag in response time.
