Water cooler range
offers
reliable active/passive cooling
Intertec has launched a family
of high-performance water
coolers, specially designed
to work in combination with
passive cooling systems. The
combination of active and pas-
sive cooling technologies provides
process control and instrumenta-
tion engineers with the means to
configure field protection cabinets
and shelters with extremely reli-
able cooling. The combination is
ideally suited to protecting remote
and mission-critical control and instrumentation equipment.
The two cooling technologies can work together to handle
extreme climatic conditions, or maintain continued operation
in the event of one system failing. Should electrical power fail
completely, the passive cooling system continues to operate
indefinitely –maintaining lowshelter temperatures until main-
tenance work can be performed.
ThenewfamilyofIntertecwatercoolers–dubbedHybricool
– are housed in tough GRP enclosures, which are suitable for
use in the harshest of environmental conditions.
Hybricool water coolers offer an IP rating of IP65 and can
alsobe provided in versions suitable for use inhazardous areas.
A range of sizes and cooling capacities allows users to select
optimal cooling solutions for all common scales of outdoor
protection applications from enclosures, to larger cabinets
and walk-in shelters.
Passive coolingoperates bynatural convection and requires
no electrical power. Intertec’s passive cooling systems typically
employ water as a medium to store the coolness of the night
and use it to moderate temperatures throughout the day. This
form of cooling is widely used for ‘off grid’ applications where
electrical power is unavailable and/or unreliable, and in remote
locations, such as on SCADA systems for pipelines and oil and
gas wellheads.
A passive cooling system can typically limit the maximum
internal temperature of cabinets and shelters to around 10 °C
above minimum night-time temperatures, making it ideal for
applications in arid and desert climates.
The addition of an Intertec Hybricool water cooler reduces
the dependence on low night-time temperatures, opening up
applications inamuchbroader rangeof climates andgeographi-
cal locations. Such hybrid or ‘semi-passive’ cooling systems
combining active and passive cooling technologies can easily
be configured to maintain internal shelter temperatures at
20 °C or less.
