Double centralized circuit with two independent temperatures
This type of circuit is used to provide two independent water
temperatures, to chill different users with:
one circuit designed to chill low temperature users (such as moulds) using
one circuit designed to chill medium-high temperature users (such as the
hydraulic systems) using free-coolers;
the free-coolers provide water/brine cooling without any compressor, thus
performing energy saving
Integrated solution with a second free-cooler combined with the chiller on
the low temperature circuit to reduce power consumption and save energy
Installation of a second free-cooler – pressurized circuit with
During the hot seasons the free-coolers provide cooling for the hydraulics
of the inj.moulding machines;
During the cold seasons one free-cooler provide cooling for the moulds, the
second free-cooler keeps on cooling the hydraulics of the inj. moulding
Higher energetic efficiency (the fluid in the high temperature circuit
requires a lower power consumption);
better temperature control of the hydraulic oil (constant temperature along
Annual energy saving can
be up to 90% !
Integrated solution with FCE self draining free-cooler in an
existing pressurized circuit – no glycol FCE
With the self draining solution glycol is not necessary.
The FCE self daining free-cooler is installed in outdoors and operates
automatically when ambient air is sufficiently cold; this provides a
pre-cooling of water in the free-cooler reducing the operating time of the
When the system is not working or in case of black-out, the FCE unit
automatically drains the water preventing freezing, even if no glycol has been
added to water.
Benefits: Energy Saving
the free-cooler has no compressor and uses ambient air to directly cool
reduced environmental impact as no glycol is necessary.
