Closed-Circuit Cooling Towers

A double advantage for your system with closed circuit cooling towers: the efficiency of evaporative cooling plus fluid “protected” inside a closed circuit. Easy access and maintenance to the internal coils, fiberglass basin and a possibility of free cooling mode.

Indirect exchange coolers are a valid alternative to the open circuit especially to keep the fluid unpolluted: the latter (usually water or water plus glycol) passes through a tube bundle and does not come into contact with the cooling water.

In addition to the closed circuit cooling tower, a hybrid cooler or “hybrid closed circuit cooling tower” (as it is sometimes improperly defined) can be used: it is a device which operates in evaporative (wet) or dry (dry) mode depending on the external temperature or the temperatures of the fluid to be cooled.

Some advantages for all closed cooling towers and “hybrid towers”.

  • Ideal if the coolant cannot be polluted from the outside or for free cooling.
  • High efficiency.
  •  Different solutions to reduce sound emissions
  • Totally removable side walls for an easy and total access to the internal parts, to simplify inspection, cleaning or maintenance operations.
  • Special dimensions for shipment by sea containers.

MITA Service and MITA Connect complete the offer at the customer's request: pre- and after-sales service, spare parts and remote monitoring of the evaporative cooler for efficient data collection and predictive maintenance.

    Cooling technologies for a high-quality food process

    More than a hundred years ago it was just an apple orchard: now it is one of the leading food industries in Sweden. This is the company to which MITA Cooling Technologies and CAMPreq have provided their solutions – respectively as a manufacturer and a cooling process advisor. In the food & beverage sector, it is important to preserve the quality of the finished product even more than in other industries: therefore, the cooling circuit must play its part. Closed-circuit evaporative towers meet this need better than other solutions.

    Creta Farm cuts energy bill with Mita adiabatic technology

    After a devastating fire Creta Farm decided to rebuild and install a cutting edge energy efficient solutionfor the production plant in Crete. The prestigious assignment to design the new cold storage went to ecoRef in Athens. They designed an indirect cooling system with R407F and Temper -15 as secondary fluid using adiabatic Mita technology. The results have exceeded the expectations with significantly reduced energy costs.
