General Product Information
IGH EFFICIENCY
H
The design of the plates creates two separate channels
for a true counter current flow movement. This complex
hannel system results in high turbulence and high heat
c
transfer.
MATERIALS
The standard TTP Braze Plate Heat Exchanger has
plates and connections made of AISI 316L stainless
steel. The brazing alloy is 99.9% copper. An optional
TTP Braze Plate Heat Exchanger with marine grade
stainless plates and nickel brazing material is available,
see Notice on page 3. The use of these materials provides a high degree of corrosion resistance and suitability with a wide variety of fluids.
SELF CLEANING
TTP Braze Plate Heat Exchangers operate with high turbulence flow, even at low flow rates. This high turbulence keeps small particles in suspension minimizing
fouling and scaling.

General Installation
GENERAL INSTALLATION REQUIREMENTS
Ensure all plumbing / piping meets or exceeds
all local, state or national codes.
- Use isolation valves to isolate system components
- Install unions for easy removal of the braze plate
heat exchanger. It is recommended to use
dielectric unions or couplings to protect fittings
from corrosion when connecting dissimilar materials such as copper and galvanized iron pipe.
- Provision should be made to allow for thermal
expansion or vibration.
- It is recommended to provide provisions for back
flushing and / or chemical in-place cleaning.
- A water strainer is recommended on the water
inlet circuit to protect the heat exchanger from
restricted flow rate and/or blockage. The strainer should have a 16-20 mesh as minimum, a 2040 mesh is recommended.
OUNTING GUIDELINES
M
• The heat exchanger should be mounted in a manner
that allows sufficient space to perform maintenance.
• It is recommended that the heat exchanger be
mounted in a vertical position with the colored label
on the left side of the installation. When space and
piping restrictions require another position, the following guidelines should be applied:
Liquid-to-Liquid Single Phase Applications
- The heat exchanger can be mounted in any position that does not create the possibility of trapping
air or other gases in the heat exchanger.
- If the heat exchanger must be mounted with the
connections on the side, orient the heat
exchanger so that the connections for the fluid
likely to have entrapped air is at the top.
Two-Phase Applications
- Flush all piping prior to connecting to the heat
exchanger.
- Provisions should be provided in the piping to
allow air elimination and drainage of the system.
NOTICE
When boiler water is utilized as the hot water circuit,
a strainer may not be required on the inlet side of the
heat exchanger provided a water strainer is incorporated as an integral component in the boiler system.
WARNING
To prevent the over-pressurization of the heat
exchanger, a safety relief valve should be installed
in the piping in the vicinity of the heat exchanger.
The safety relief valve, if required, is to be provided
by the installer.
- The heat exchanger must be mounted in a vertical position.
NOTICE
For steam applications the heat exchanger must be
mounted in a vertical position only.
WARNING
The heat exchanger may have sharp edges.
Exercise caution when handling. Wear gloves.
- It is recommended that the heat exchanger be
supported by a bracket or stand with a bottom
support.
NOTICE
The heat exchanger should not be supported solely
by the piping or connections.
- Insure that severe vibrations or pulsation cannot be transmitted to the heat exchanger.
Install vibration absorbers in the piping and use
vibration absorbing material between the heat
exchanger and the equipment as needed.

1. Degrease and clean the soldering surfaces on
the piping and the heat exchanger connections.
2. Apply the flux to both surfaces.
3. For refrigerant applications, purge using dry
nitrogen gas on the refrigerant side to prevent
internal oxidation.
4. Heat the soldering area to approximately 1200ºF
(650ºC). Use a wet cloth to protect the heatexchanger while brazing.
WARNING
Do not heat the soldering area higher than 1200ºF.
Damage to the heat exchanger brazing material
could occur.
5. Keep the piping in a fixed position and apply the
solder.

General Installation
WARNING
Do not braze the heat exchanger in a horizontal or
lat position. Solder material may fall into the heat
f
exchanger or piping connection, creating a blockage
within the distribution channels . Direct the flame
away from the heat exchanger
Fig. 4: Solder Connection
WARNING
Do not heat the welding area higher than 1200ºF.
Damage to the heat exchanger brazing material
could occur.
Fig. 5: Welded Connection
THREADED CONNECTIONS
WELDING PROCEDURES
1. Prepare the edge of the connecting pipe for
welding with a 30º angle chamfer.
2. Place the connecting pipe into the heat
exchanger connection.
3. Use TIG or MIG/MAG welding method filling the
groove form by the two edges.
4. For refrigerant applications, purge using dry
nitrogen gas on the refrigerant side to prevent
internal oxidation.
5. Heat the welding area to approximately 1200ºF
(650ºC). Use a wet cloth to protect the heatexchanger while welding.
WARNING
When using electrical welding circuits, connect the
ground terminal to the joining tube, do not connect
to the back of the heat exchanger. Damage to the
internal channels and/or brazing material of the heat
exchanger could occur.
General Guidelines
• Use Teflon or Mylar tape or other sealant on the
male threaded part of the heat exchanger connection to prevent leakage.
• Use a back-up-wrench method when installing
threaded connections. DO NOT over torque the connection. Over tightening connection will damage the
heat exchanger.
6
Maintenance and Cleaning
ENERAL GUIDELINES FOR CLEANING
G
• A 5% solution of Phosphoric Acid or Oxalic Acid is
ecommended as a cleaning solution. Other types
r
of cleaning solutions such as ice making machine
de-scaler are available and may be used, check the
manufacturer’s instructions for compatability.
• Do not heat the acid solution when back flushing
through the heat exchanger.
• Flush the heat exchanger with fresh water when the
cleaning process is completed. A final rinse using a
solution of 1 to 2% sodium hydroxide (NaOH) or
sodium bicarbonate (NaHCO3) ensures all acid is
neutralized.
• For optimum cleaning the cleaning solution flow rate
should be a minimum 1.5 times the normal operational flow rate and preferably in a back flush mode.
WARNING
To prevent damage to the heat exchanger and refrig-
rant components, do not chemically clean the
e
refrigerant circuit of the heat exchanger.
NOTICE
In some applications the heat exchanger may be
subject to severe conditions, including high temperature and/or hard water conditions, causing accelerated scaling and corrosion rates, which will alter the
performance of the heat exchanger. In applications
where these factors are present it is important to
establish a regular maintenance and cleaning
schedule.

DOMESTIC WATER APPLICATIONS
• Typically the fluid circuit with the highest temperature and/or pressure should be connected to the left
side connections as indicated with the colored label.
• The circuit flows should be piped in a counterflow
arrangement.
• On instantenous water heating applications (applications without any storage tank) a flow switch must be
used to prevent overheating of the heat exchanger.
• A three-way tempering valve/anti-scalding safety
device is required.
DANGER
Fig. 8: Domestic Piping Arrangement
HOT WATER CAN SCALD!
• Water temperatures over 125ºF can cause
severe burns instantly, or death from scalds.
• Feel water before bathing or showering.
• Consumer Product Safety Commission and
some states recommend temperature settings
of 130ºF or less. Setting thermostat higher than
130ºF will increase the risk of scald injury and
cause severe personal injury or death.
• Water heated to a temperature suitable for
clothes washing, dish washing and other sanitizing needs will scald and cause permanent
injury.
• Children and elderly, infirm, or handicapped persons are more likely to be injured by hot water.
Never leave them unattended in or near a bathtub. If anyone using hot water in the building fits
this description, or if state laws or local codes
require certain water temperatures at hot water
faucets, take special precautions.
- Install an automatic mixing valve at the heat
exchanger or at each hot water faucet, bath
and shower outlet. Selection and installation must comply with valve manufacturer’s
recommendation and instructions.
- Use the lowest practical temperature set-
ting.

TEAM TO WATER APPLICATIONS
S
• Ensure the braze plate heat exchanger is mounted
vertically to allow gravity drainage of the condensate.
• The installer should use “Good Steam Practices”
which include a steam trap below the unit and vacuum breakers.
• The steam circuit must enter the heat exchanger’s
top connection, with the condensate leaving the heat
exchanger through the bottom connection.
• Provide steam traps at critical points e.g. in front of
the control valve, to prevent “pooling” of condensate.
NOTICE
Water Hammer and Other Deformations Caused By
Wet Steam: A high moisture content in the steam
could condense within the heat exchanger forming
pools of water at critical points, exposing the system and the heat exchanger to water hammer. One
critical point is the area ahead of the control valve
when the valve is located ahead of the inlet to the
heat exchanger. When the control valve is in the
close position the stationary steam in front of the
valve is subject to condense. Heat losses due to
radiation and/or faulty insulation can increase the
rate of condensation. Also, when the control valve
is in the closed position, condensation on the plates
of the heat exchanger occurs, producing a vacuum
or negative pressure inside the heat exchanger.
When the control valve opens to admit steam to the
heat exchanger, the differential in pressure causes a
sudden acceleration in the steam flow, pulling the
accumulated water into the heat exchanger at a high
velocity. The amount of energy produced by this
water at a high velocity can be very great, resulting
in heavy wear and tear and other mechanical damage in the heat exchanger, which results in potential
leaks.
Avoidance Practices: On low pressure steam systems or on applications with no-continuous processes, place traps prior to the control valve and other
critical points in the steam distribution system.
NOTICE
For sizing applications using steam it is recommended to contact Triangle Tube’s Engineering
Department.

APPLICATIONS
Condenser Applications
The heat exchanger must be mounted in a vertical
•
position to allow gravity drainage of the condensate.
• The refrigerant gas
must enter the heat
exchanger on the left
side (as indicated by the
color label) using the
upper connection.
• The cooling water must
enter the lower right connection of the heat
exchanger and exit from
the upper right connection. This will maintain
the counter flow concept.
Fig.13: Condenser
Applications
Evaporator Applications
• The heat exchanger must be mounted in a vertical
position.
• The refrigerant gas/liquid mixture must enter the
heat exchanger on the left side (as indicated by the
colored label) using the lower connection.
• The water must enter the upper right connection of
the heat exchanger and exit from the lower right connection. This will maintain the counter flow concept.
• The thermal expansion valve should be placed close
to the inlet connection of the heat ex- changer. The
thermal expansion val- ve
sensing bulb should be
placed on the refrigerant
outlet pipe approximately
12 to 24 inches from the
heat exchanger.
• A pressure differential
switch or flow switch
must be installed to prevent possible freeze-up
due to loss of water flow.
