Performance Field
The Environment is
Always a Consideration
Not only do these pumps use 80%
less energy (Meeting EU legislation
with ˝A˝ class energy rating) than a
standard commercial pump but
we also made the choice to use
components, processes and manu-
facturing capabilities which keep
the environment in mind. For
instance all of the magnets used
in the Viridian are time stable, non-
toxic ceramic magnets as opposed
to the more widely used rare earth
Neodium compounds which are
sourced only from Chinese mines.
Heating, Air Conditioning or
Chilled Water Systems
Taco Viridian pumps are built around
exacting specications to meet the
widest range of closed loop hydronic
heating and cooling applications.
They are suitable for use with uids
at temperatures from 14°-230°F (-10°
- 110°C), feature 175psi working pres-
sure and have a stainless steel impel-
ler and shaft. Continuous duty rated
with a built-in soft start-up circuit the
VR15 and VR20 can accept 110-240
volts and the VR25 and VR30 operate
on 230-240 volts supply power.
Lower Installation,
Commissioning and TCO Costs
A simple ethernet connection on the
pump gives instant remote control,
monitoring and adjustment without
requiring highly skilled network IT or
commissioning personnel. Any Virid-
ian pump can be accessed directly
through a common cross-over cable
from a connected laptop or through
a web enabled computer or smart
phone.
The in-line design and standard ANSI
class 125 anges make for a techni-
cian friendly installation. The pump
and motor form an integral unit with-
out a mechanical seal. The bearings
are lubricated by the pumped uid,
ensuring years of quite, maintenance
free operation.
To protect your investment in the
Viridian it provides overcurrent, line
surge and current limit protection,
thermal monitoring, heat sink status
and over temperature protection.
A convergence of efficiency, simplicity and technology; Taco introduces a new generation of wet rotor circulators
Given all the advantages stated above,
the total cost of ownership (TCO) of a
Viridian pump is by far the lowest for
its performance range.
Web Based Simplicity
Simply launch any common brows-
er, like Internet Explorer or Firefox,
type in “VIRIDIAN” or the pump’s IP
address in the browser’s address
line and you have instant, automatic
and full control over the pump(s).
The HTTP or FTP protocol ensures
a user-friendly, commonly used
environment.
