MITA Cooling Technologies has delivered an efficient cooling system for a water treatment machinery manufacturer in India’s textile sector. The installation, a PME 4804 E cooling tower in Container version, reduced the temperature of solids-laden effluent from 45.4°C to 35.5°C. By consulting at all stages, MITA ensured high performance and long-term reliability.
In 2024, an international water treatment machinery system integrator expressed a need for a cooling system to treat the wastewater of a textile customer based in Dhaka, India.
The objective was to cool process water containing suspended solids (over 700 ppm) from an initial temperature of 45.4°C to an outlet temperature of 35.5°C. The system had to operate in a climate with ambient air at 34°C (dry bulb) and 29°C (wet bulb), providing a thermal output of 2,580 kW. A further key requirement was durability for long-distance transport, given the significant distances involved.
MITA Cooling Technologies supplied an open cooling tower model PME 4804 E CONT GS-ATT, equipped with “Splash” exchange pack specifically for water with high amount of suspended solids. The Container version, selected to meet the need for long-haul transportation, facilitated relocation and installation in Dhaka. The tower body is made of non-corrodible fiberglass, the metal parts of AISI 304 stainless steel: this ensures durability of the system.
In addition, MITA provided consultancy at all stages of the project, from initial design to after-sales, ensuring support and performance optimization for the client at every stage.
The solution met the customer’s needs for energy efficiency and cooling capacity, keeping wastewater below the required temperature and reducing the environmental impact of the textile production process.
The main success factors were:
The different phases of the industrial water treatment process require defined cooling temperatures in accordance with regulations. In this sector, it is preferable to use cooling towers with anti-clogging fill packs for industrial contaminated water.
The demands of these industries are linked to the most variable temperature changes, depending on the single production process. An example is the drying of leather in tanneries, carried out thanks to vacuum pumps: the liquid ring of these tools is cooled by a cooling tower. Usually, dirty water is treated: for this very reason, open cooling towers with wide-passage exchange packs are suggested. The durability of the solutions adopted is appreciated: fiberglass is a plus.
A light and non-corrodible open-circuit evaporative cooling tower: process industry and HVAC operators will be able to count on its multiple versions and ease of transport and installation.
In 2019, MITA Cooling Technologies sold 4 PME-E open circuit cooling towers to a Swedish paper mill. The "Super Silent" version of the PME-E makes it possible to meet the customer's extraordinary low sound level requirements.
