Designed to significantly advance pumping systems for
commercial buildings, Grundfos has introduced a
state-of-the-art TPE3 in-line pump that features
best-in-class technologies that deliver greater efficiency
for heating and cooling applications. The newest addition to
Grundfos’ portfolio of intelligent pumping solutions, the
TPE3 showcases a Permanent Magnet Motor, leading-edge
hydraulic efficiencies, a series of advanced control modes,
multi-pump functionality, and easy install, monitoring and
commissioning that boost system efficiency and deliver
overall greater heating and cooling performance.
Balanced systems without balancing valves
The TPE3 is more than a pump: Grundfos’ Flow Limiting
Function eliminates the need for a pump balancing valve and
thereby reduces the pressure loss. This improves the overall
performance of the system and reduces initial costs.
Moreover, it features a built-in heat energy meter that can
monitor heat energy distribution and consumption, preventing
excessive energy bills caused by system imbalances.
Integrated ΔT control
With the TPE3, the ΔT is never too high or too low. TPE3’s
integrated ΔT control cuts down on the costs of a
differential temperature sensor, as it can operate based on
the measured difference between flow temperature and return
temperature. This is done via the built-in sensor and
connecting one external sensor directly to the TPE3, which
allows the pump to take charge of the system’s need for flow
based on differential temperature.
Optimized applications
The TPE3 is an all-round in-line pump that can be used in
all heating, cooling and district energy systems. In some
applications, the TPE3 makes an especially significant
difference in terms of comfort and system efficiency –
examples include:
Increased boiler protection
Use in non-condensing boiler systems results in increased
boiler protection and reduced operation costs. Combine the
TPE3 with an external temperature sensor that measures the
return water temperature. By adapting the flow in the
by-pass line, the pump is in charge of the water temperature
entering the boiler, which ensures that the right
temperature is maintained at all times.
Increased system efficiency in single-pipe heating
systems
The TPE3 is useful in one-string heating systems, increasing
system efficiency. In single string systems, the design is
typically made with constant flow. The result is increased
return temperatures from the system in low load situations.
A TPE3 pump solves this problem and ensures that ΔT is
maintained as originally intended.
For domestic applications: Hot water guarantee
without the energy waste
In domestic hot water applications, instant hot water is
required when the tap is opened. Traditionally, a throttled
constant speed pump runs around the clock every day to
ensure this, wasting significant amounts of energy. The TPE3
has a temperature control mode – based on the signal from
either its own internal temperature sensor or an external
sensor, the pump will continuously maintain the desired
temperature of the water.
Multi-pump functionality
Wireless technology enables the TPE3 to connect with up to
four single TPE3 pumps – they can be controlled jointly in
either cascade mode, alternating mode or duty/standby
without the need for any other pump controller unit.
Built for easy monitoring, installation and commissioning
With many configurable relays and analog inputs, the
complete TPE3 I/O package allows for better system
monitoring and optimal pump regulation. It also comes packed
with functionalities that allow for easy installation and
commissioning via the pump display, including the
possibility of connecting to Grundfos GO for intuitive
handheld pump control and full access to Grundfos online
tools.
