Fonderia Casati is Industry 4.0 also thanks to MITA cooling systems

Cooling technologies to support not only a process but a future vision of the business.

Fonderia Casati, a long-standing company based in Varese, has no doubts on what it will take to keep its competitiveness at European level: the automation of its industrial processes, by implementing an integrated data flow between its production line and management control.

MITA Cooling Technologies, therefore, provided this customer with an evaporative tower and a cooling management and monitoring station: the data collected by the system will, in fact, be sent to the company’s internal management and will help optimize the production processes.


1. The Company: the vision of a “4.0 foundry”

All brands in Europe mount on its engines a piece that comes from Viale Belforte”, explains the following Italian video produced by the Unione Industriali di Varese. It also explains Fonderia Casati’s approach to Industry 4.0 as its corporate philosophy.



Since 1972 the Company has been producing castings made of special cast iron and stainless steels: turbo-compressors, turbo-manifolds, exhaust manifolds. The main customers are the European players in the automotive sector, but also the Varese brand also serves the naval sector and other general mechanical industries.

For some years now, the company has actively pursued the topic of industrial automation: Fonderia Casati manufactures its products using lines that are almost totally automated, generating a unified data flow from the plant to the company’s management. This also cuts water and energy consumption to increase the factory’s environmental friendliness.


2. The needs: cooling and control of process water

Scheme of a Cooling Tower for a Foundry

Fonderia Casati has installed a new induction furnace in its historic headquarters in viale Belforte in Varese: once again, in this case, Fonderia Casati turned to MITA Cooling Technologies to handle the cooling process, as it had already supplied the plant with a PME-E evaporative tower.

The new system’s requirements (around 400 kW, 10 °C temperature difference) were lower than the previous MITA project. In this case, however, it was necessary to supplement the cooling system with the automation of the industrial process developed in recent years by the Varese-based company.

Naturally, one objective was to take advantage of the hyper-amortization benefits, provided by the Ministry for Economic Development for the acquisition of goods and technologies that enable transformation in the direction of Industry 4.0.

3. The solution: PMS tower and 4.0 cooling station

Fonderia Casati selected an open-circuit PMS tower, consisting of a single non-corrodible fiberglass block, suitable for small installations.

It is small in size, but with great opportunities for use: this especially if it is integrated through hydraulic connections and sensors to an automated cooling station. The MITA Systems cooling station is in fact composed of:

  • a reinforced concrete tank, with a central dividing wall that allows the separation between hot and cold water; and
  • a technical room for the coordination of all its typical functions using an easy-to-use touch-screen PLC.

The basic version of the cooling unit provides energy and water savings thanks to the automated regulation of a number of parameters:

Cooling Station for Fonderia Casati
  • the operation, management, and control of the pumping unit and fan motor unit,
  • optimization of water pressure,
  • optimization of water salinity,
  • checking the water level in the tanks,
  • tower water treatment also thanks to the dosage of anti-scale-anticorrosive-algae additives.

There is more. The customer can remotely view the parameters monitored by the Easybox cooling unit and report them to its management software: this is also required by Fonderia Casati, in its objective to be an Industry 4.0 foundry. An Ethernet connection was therefore provided between the various system components and the external data exchange over Modbus TCP communication protocol.

The entire system had low installation and maintenance costs: the components of the cooling unit are in fact pre-assembled and assembled on site using galvanized steel hardware. This facilitates disassembly even in the event of any maintenance operations.
