Case history

FRANCE

The cooling of the plastic recycling process

REQUEST

Cooling of a plant for plastic recycling process composed by extruder with by 650 kg/h capacity.

SOLUTION

With the aim of:
  1. reducing the risk of waste
  2. increasing the rate of production
  3. reducing costs
Eurochiller, together with its cooling specialists, decided to provide a solution with 1 AXEVO A 195 FT connected with a GRP, which is a combination of pump and tank. By that we can allow the customer to increase the production rate because this combination is connected to the heat exchanger and the goal is to have a bigger thermal vessel to guarantee a most precise temperature to the process and a better energy efficiency during use of compressor.

POLAND

No-glycol cooling of extrusion and injection lines

REQUEST

No-glycol centralized system to cool down both PP extrusion lines and injection moulds.

SOLUTION

To respond to this request, EUROCHILLER has provided an innovative solution combining a traditional chiller with a self-draining free-cooler of its TFC line.

In its self-draining version, the TFC allows to avoid on the one hand the use of glycol (which is expensive and highly harmful to the environment) and on the other one the use of heat exchangers (with considerable money savings and a remarkable increase of the cooling capacity) as water coming from the chiller is addressed straight to the use. The risk of icing (deriving, for example, from a production break due to winter maintenance or from a sudden electrical black-out) is avoided thanks to the use of a system able to automatically and completely drain the water into the coils inside a collection tank, thus avoiding the formation of ice.

ITALY

The cooling of blown film lines

REQUEST

Cooling of 1,4 MW blown film lines. Customer’s must: safeguard the environment and get the best quality and performances ever.

SOLUTION

Supply of 2 x TFC-S-A 700 with integrated free-cooling, whose installation allowed the customer a yearly savings of 793.824 kW energy, which in money is € 90.000 per year.

Pay-back for the higher investment was returned in 10 months.

CHILE

The control of temperature into laminating processes

REQUEST

In the flexographic printing as well as in the lamination processes, the painting applied on a plastic or paper substrate is dried in the “drying tunnel” placed in the upper part of the machine, to prevent the painting from being damaged during wrapping. In the past, the control was made with hot ventilated oil. The boilers are now in disuse and this is why, as in our case, high temperature electric oil heaters are used. The request of our Chilean customer pointed to a unit with diathermic oil providing for 130 kW of heating, with oil at 230°C.

SOLUTION

Supply of an oil temperature control unit of our ET series, version S for 230°C diathermic oil, heating capacity 144 kW, pump flow rate 350 lt/min and cooling capacity of 45,000 kCal/h.

ITALY

The thermo-cooling into food industry

REQUEST

The importance of a proper thermo-cooling in the process of topping and filling of cream into snacks: it is essential the ongoing monitoring of the final product to prevent the food deterioration during production.

SOLUTION

Essential in this application is the proper relationship between the temperature of thermo-regulated water and that of the product being processed in the emulsifier and the transport lines to the topping/filling heads.

Thanks to peripheral pumps with high head and to stainless steel heaters controlled by a safety thermostat, our 3 Flows temperature controllers were found to be absolutely indispensable to our customers to manage the excessive pressure drops of the plants for cream transport.

CONGO - COSTA D'AVORIO

The cooling of bread lines

REQUEST

The manufacture of a Bulangerie is much complex and only the choice of the right partners may grant a good result. A prominent aspect involves cooling, the control of the rising room and the correct cooling of water for the dough, all factors that, together with the right temperature into the rising room help to let the final product be fragrant and scenting.

SOLUTION

Eurochiller has manufactured three big plants to be installed in Africa where the average production rate per day is of 500/800 T.

The project, developed in cooperation with Mecatherm (a leading French company into this field) has three distinct cooling units: 1) Air handling into the rising room by means of direct expansion chillers, 2) Cooling of water for the dough by chiller, tank and exchanger, 3) Cooling of water for the rising rooms.

K.S.A.

The cooling of oil drills

REQUEST

Supply of three 40 ft containers housing chillers for the production of water destined to the cooling of oil drills. The transfer of the chillers group made with engine and trailer on dirt roads, the likely sandstorms coupled to temperatures sometimes over 55°C called for an in-depth research and for the design and the manufacture of a sturdy and strong structure.

SOLUTION

Manufacture on exclusive design of three 40 ft containers complete with cooling section, air conditioning inside of the containers to prevent overheating, strong structure able to stand the adverse ambient conditions.

U.K.

The cooling of alternative sources of energy

REQUEST

Closed circuit cooling of a test bench to test under extremely hard working conditions, the efficiency of wind and marine turbines.
Units to cool down the mechanical/electric parts of the movers which, due to the friction, get overheated, with particular regard to the inverters giving out the energy produced by the motors of the wind or marine turbines.

SOLUTION

Supply of 2 x ADcooler 600 with Alu-Coat condenser and special surface painting to stand the raised salinity level into the air due to the location of the plant close to the sea.

ITALY

The cooling of chocolate and cocoa

REQUEST

When the management of the Italian branch of a Swiss world leading’s company was contacting us, their demand was to cut 30% of energy consumption and 90% of water one (applied to condensate the compressors).

Required targets, in details, were the following:
1. to spend energy exactly where this was required, i.e. to apply different temperatures into the different production depts;
2. to spend energy with the highest efficacy level;
3. to reduce the water consumption as much as possible.

SOLUTION

Eurochiller satisfied customer’s demands as follows:
1. supplying special water-cooled, direct expansion ABF units;
2. taking advantage of the Inverter technology;
3. replacing an open cooling circuit (evaporating tower) with an highly efficient, closed circuit system with our ADcooler (adiabatic dry-cooler).

ITALY

The cooling of tunnels and galleries

REQUEST

Improvement of comfort, of quality of air and of powder concentration during boring operations.

SOLUTION

Centralized air conditioning thanks to an enbloc chiller manufactured by EUROCHILLER to be coupled to a primary fan system (manufactured by SYSTEMAIR) on boring side, without changing its structural characteristics and its size.

INDIA

The cooling of cement

REQUEST

Improvement of the adverse ambient conditions on site (a limestone quarry), with temperatures above 50°C with R.H. close to 90% which also require a sub-cooled cabinet. We had also to take into consideration the quantity of dust in the air, the voltage peaks generated by the feeding of the quarry generators with 1000V cables, as well as the shortage of rtop-off water in an unattended area, and finally the presence of rodents of the jungle that could damage the (armed) power cables of the chiller.

SOLUTION

Supply of 3 cooling machines designed to cool VFD (Variable Frequency Drive) Inverters for medium voltage (average capacity 2300 kW).

These inverters control the process fans by sucking hot air which on its turn passes through electro-filters and breaks breaks down the pollutants (sulfur and Co2) present during the clinker burning process. Our AX units have been designed with the logics which is required for the delicate cooling on the inverters,which means: full and complete redundancy of operation and complete monitoring (by PLC) of the machine status and of the correct operation of the whole system.
