Originators of the “Flexible Water Tube” design
Bryan Water-PakTM brings packaged efficiency
to large volume hot water needs
Efficient
“Flexible
Water
Tube”
Design
Bryan Indirect Water Heaters incorporate the
Bryan bent water tube that provides rapid
internal water circulation. The result is maximum heat transfer, and the flexible tubes eliminate the chance of thermal shock. All tubes are
easily removable and replaceable without
welding or rolling.
Bryan
Heat
The Bryan Water-PakTM Indirect Water Heating System is a
proven method of providing large volumes of hot water, with
intermittent draws, for a variety of applications. Circulation
between the tank and heat exchanger maintains the required
temperature in the tank. Our years of experience in this field
have perfected the Bryan Indirect Water Heater.
Simplicity of Indirect Heating
The indirect heat exchanger method of heating water is
extremely simple. The primary water in the heater is maintained at a constant temperature and recirculated only within
the heating vessel. The heat exchanger, placed in the primary
water, absorbs heat and transfers it to the water flowing
through its copper tubes.
Efficiency in a Compact Unit
The Bryan Water-Pak is a completely packaged system
comprised of the Indirect Water Heater, Storage Tank and
Circulation Piping, all mounted on a structural steel skid. All
components are factory wired and assembled, requiring field
hookup only on the cold and hot service water connections,
the electrical supply, fuel source, and the vent connection.
The Bryan Water-Pak utilizes the superior "Indirect" feature
of the water heater, resulting in a high efficient and scale-free
operation. The service water does not come in contact with
the high temperature heating surfaces, consequently, there is
little possibility of scale and corrosion. Thousands of Bryan
Indirect Water Heaters have been installed during the past 40
years, most all of them still rendering efficient service.
The Bryan Water-Pak is engineered to provide a compact
packaged unit for large volume water heating requirements.
Available in many selections of Heater-Tank combinations,
horizontal or vertical. Designed for long life, low maintenance
and continued maximum efficiency performance.
Each component of the Bryan Water-Pak is easily replaceable. The entire unit need not be replaced, as is often required
by other types of water heater equipment.
Storage tanks and water heaters comply with the recommendations of ASHRAE 90-75.
Exchanger
The heat exchanger is the key to the Bryan
Indirect Water Heater. It leads to all the advantages listed on this page, making the Bryan
Indirect Water Heater a perfect choice in dozens
of applications.
The heat exchanger is constructed of heavy
copper tubing which transfers heat from the
primary water to the water flowing through the
exchanger. The heat exchanger is designed for
two or four-pass flow with low pressure drop. It
can easily handle the entire BTU output (or any
desired portion) of the heater.

Water-Pak Selection
Water-Pak units are built to furnish a very wide selection of
recovery rates, storage capacities and configurations. Both
horizontal and vertical tanks are available to best fit into the
space allocation. In addition to the combinations of "settings"
shown below, other combinations, arrangements and sizes
are possible. Fuel selection includes gas (atmospheric or
forced draft), oil, gas-oil or electric (consult factory).
1. Select Heater Model based on "Heater Specifications" table
below.
2. Select storage capacity from "Storage Tank Specifications"
tables, horizontal or vertical tank depending on space
Selection Procedure Example
A requirement of 800 gph at 100° rise. Storage capacity 1000
gallons. Fuel, gas. Tank lining, cement.
1. From "Heater Specifications" table, select Model No. CLM120-WT Gas, rated at 1,152 gph, 40° to 140° rise.
2. From the "Storage Tank Specifications" tables, suppose
you select the 1045 gallon horizontal tank.
3. Then the setting shown in diagram "AH" (horizontal tank)
would be appropriate.
