HIGH
EFFICIENCY SHELL & COIL HEAT EXCHANGERS
Shell
& Coil Heat Exchangers are
designed for steam-water, water-water
and glycol applications. They are designed
according to the
counterflow principle for highest heat transfer efficiency.
ELGE® manufactures two styles of shell
and coil heat exchangers referred to as the Type-A
and the Type-MD. Both styles are available in
multiple sizes that can handle virtually any heat exchanger application from
60,000-to 3,600,000 BTU. The unique ELGE® shell and coil design, used for
over 50 years, has proven itself to be extremely efficient and durable. ELGE®
heat exchanger packages are so efficient that when used in a steam to water
application they will typically discharge condensate as low as 100° F
extracting nearly 98% of the usable energy from the incoming steam. When
used on water to water applications the water being heated can reach
temperatures within 5° F. of the incoming primary water source.
HIGH
PERFORMANCE: the unique coil arrangement
has
a large heat transfer area and high heat transfer coefficients.
COMPACT
AND LIGHTWEIGHT: closely packed tubes makes our shell and coil
exchangers compact and lightweight. Small footprint makes it easy to
install where space is limited and hard to access.
LOW
MAINTENANCE COSTS: corrugated tube design produces a high turbulent
flow, which reduces deposit build-up and fouling. This means longer
operating cycles between scheduled cleaning intervals.
HIGHER
TEMPERATURE DIFFERENTIALS: helical design allows for higher
temperatures and extreme temperature differentials without high stress
levels and costly expansion joints.

The Type-MD heat exchanger uses a
very specialized dimpling process on the copper coil to maximize
the surface area for ultimate heat transfer.
Each tube layer is carefully twisted along its axis inside the
copper shell maximizing the number of tubes and surface area
inside any given shell size. |

The Type-A heat exchanger
consists of a copper coil (battery) within a steel pressure
vessel. The spiral wound coil is manufactured from smooth
drawn copper tubing with a special oval cross section. This
ELGE® design maximizes the total number of copper coils that
can be enclosed in a given size shell. In addition, the coil
layers are separated by spacers forming flow channels inside
the shell. This unique ELGE® design maximizes surface area
and heat flow characteristics within the shell making it the
most efficient heat exchanger on the market today. |
