BUFFMAX Use and Care Manual (May 2016) Page 3
Section 2: TECHNICAL SPECIFICATIONS
2.1 STANDARD EQUIPMENT
The following standard equipment is installed and
supplied with the tank:
4 standard size connections
½’’ NPT automatic air vent with shut-off
valve to facilitate replacement
2 ½’’ diameter temperature and pressure
indicator.
Immerson well
3 x ½’’ connections to localize well or
adding one
Fiberglass insulation limitating the heat
loss to½°F per hour
¾’’ Drain valve
Adjustment legs
Lifting lugs (ASME 120, 175 et 200
gallons models only)
2.2 OPTIONAL EQUIPMENT
The following items are optional on the tank;
Please see the engineering specifications for
more details about the product.
2 extra tappings
Custom tapping diameters
Class 150 Flange tappings
Elastomer insulation for chilled water
application avoiding condensation risk.
2.3 BUFFER TANK
The BUFFMAX optimizes runtimes and limits
on/off cycling of the energy source. When the
minimum system load is lower than the energy
source’s minimum capacity, the system will
generate short cycles. This causes premature
wear of the equipment and substantially
decreases the system’s energy efficiency.
2.4 STORAGE TANK
Any hydronic heating system with the BUFFMAX
stores energy like a battery. When a demand is
made for limited heating (for example, when
there is little difference between indoor and
outdoor temperatures) or when it is used with a
low-capacity energy source, the energy required
will first come from the tank’s thermal storage.
2.5 HYDRAULIC SEPARATOR
Adding a BUFFMAX tank to a hydronic heating
system helps to evacuate air, eliminates
impurities, and ensures the optimal functioning of
the pumps—not only for the energy source but
also for the distribution system.
