Obvious though it seems many facilities with steam-generating capability
overlook the economy and convenience of using some of that steam to heat water
or other liquids.
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 two steam inlet pressure
ranges: 2-15 or 15-200 psig. Heating is instant on demand and capacity can be as
much as 7,200 gallons per hour. Temperature variation is a maximum of ±4°F.
The standard coil material is copper but Admiralty and cupro-nickel coils are
available as special-service options.
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.
Should movement of the blending valve be restricted by foreign matter carried
in the water flow a yielding spring arrangement allows the diaphragm and stem to
move up uncovering a heat damper, the characterized blending valve. This damper
allows more cold water to enter the blended mix eliminating the possibility of
overheating or scalding.
Available sizes include 15, 30, 45, 60, 75, 90, 105 and 120 GPM models with
adjustable ranges from 105°F to 180°F.
Skidded Heater Systems
As installation costs increase and manpower availability decreases, it is
more important than ever to find the most economical method of installing
equipment. In most cases installing it yourself would cost less than hiring an
outside contractor, if you have the manpower, the time, and the expertise to
install the equipment. (when installing even the simplest piece of equipment, it
takes time to read the instructions, determine the materials needed, purchase
the materials, and complete the installation.)
The Skidded Concept
The skidded Constantemp® water heating system solves this problem by placing
the entire system complete with steam traps, strainers, gauges and
interconnecting piping on a frame or skid. Connect the steam, water, and
condensate piping, and the unit is ready to use.
All the guess work and preparation time is eliminated, and Leslie assumes
full system responsibility. There is never a question as to pipe size, distance
to the steam reducing valve, or proper trap installation. All the work is done
for you except for the utility connections.
The standard package has everything necessary to operate the heater. Optional
equipment available includes recirculation pumps, pumping traps, steam reducing
valve, and redundant safety shutdown devices. All connections are flanged and
are placed at the edge of the assembly. Even the largest unit will fit through a
standard doorway. Or we can custom design a complete system to suit your unique
requirements. Everything you need to get yourself in hot water FAST -
