Rittal’s Blue e cooling units have the
same nominal cooling output,
physical size and cut-out
dimensions as equivalent Rittal
Basic cooling units and are reported
to be capable of energy savings of
up to 45%.

With additional monitoring
functions on the 7-segment display
that include high condensate level
warning, clogged filter mat alarm,
enclosure internal temperature and
any error messages, the health of the
unit can be checked at a glance.

Suites of encosures that are not
divided internally may need
multiple cooling units to function as
a system. Using the SK BUS system,
up to 10 Rittal Blue e cooling units
may be connected in a master and
slave configuration.

Adjustment of the minimum
cooling setpoint of 20°C and the
switching hysteresis in the range 2
to 10K, which governs when the
unit switches off, is easy using
buttons on the fascia of the
controller. Passcode protection is
included.

Prices of Blue e cooling units
have been reduced; the maximum
premium
compared to
the equivlent
Rittal Basic
unit is now
10% and in
eight
instances the
Blue e cooling
unit is said to
be the more
cost effective.
