1. Large volume systems with high
mineral content in water.
2. Systems exposed to untreated
quantities of makeup water.
3. Old systems severely contami-
nated with scale and rust buildup
inside piping and heat distribu-
tion units.
4. Process applications.
5. Commercial service water ap-
plications.
6. High water pressure applications,
requiring pressure relief setting
in heating system more than 30
PSIG (tall buildings). See notes
below.

Notes:
1. Contact heat exchanger manufacturer for heat exchanger
shell-side and tube-side piping and circulator require-
ments. Tube-side flow and temperatures must meet
heating system requirements.
2. Contact heat exchanger manufacturer for sizing heat
exchanger.
3. Heat exchanger shell-side circuit requires its own expan-
sion tank as shown.
4. Heating system circuit requires its own expansion tank,
as shown, plus its own relief valve set to protect heating
system and heat exchanger piping and components.
5. When individual isolation valves are used, individual
boiler and level controls may be required.
