Centralized systems based on individual temperature control of each
consumer.
This cooling circuit is specifically designed for systems where independent
temperature control is required for each consumer:
The thermal controller is installed for each cold consumer to provide
independent temperature control and water flow;
The MINIBOX water-cooled chillers are installed next to each unit of the
process equipment requiring cooling;
The MINIBOX water-cooled chillers can be used for both cooling and
thermostating, with one or two independent circuits;
A centralized free cooling system with a dry cooling tower cools the
MINIBOX chiller / thermal chiller condensers, thermostat heat exchangers, and
hydraulic equipment drives.
Advantages:
Maximum flexibility in adjusting the temperatures and flow through the
consumer;
Precise temperature control;
Absence of marriage in the production process due to the precision of the
technology;
Optimizing cycle times and increasing productivity;
Higher energy efficiency compared to one and two contour centralized
systems;
A simpler scheme of pipelines - is lower manufacturing costs;
These central systems can easily be upgraded with the expansion of
production and improved, by adding water-cooled MINIBOX thermo-chillers and
thermal controllers as the fleet of equipment increases.
Each individual cooling unit can be equipped with a power saving system.
Free cooling mode for low-temperature circuit (cooling of molds)
The free-cooler automatically switches to a lower temperature when the
ambient temperature allows it (air temperature is 5 ° C less than the outlet
water temperature) and provides pre-cooling of the water / glycol solution in
its heat exchangers to reduce the working time of the MINIBOX water-cooled
chillers / thermochillers, this function energy saving can be realized in 2
variants:
energy saving by direct addition up the water from the free-cooler circuit
to the cooling circuit of the molds,
energy saving achieved by cooling the contour of the mold through the heat
exchanger, in this case the fluids from the mold of the free-cooler and the
molds are not mixed - it is optimal when the solution of water with glycol is
not allowed to enter the mold contour;
The free-cooler is always installed outdoors and has two options:
glycol-free version - FCE with water draining system,
free-coolers requiring the use of a glycol solution to avoid freezing at
temperatures of 0 ° C and lower.
Advantages: energy saving,
Freecooler does not have compressors and it provides cooling of water /
water with glycol, only due to low ambient temperatures.
