For the cooling of process tanks, Tempco’s TCOIL series of immersion plate heat exchangers offers a highly efficient solution. TCOIL immersion exchangers provide great flexibility in terms of footprint, as the exchangers can be sized according to both the required thermal duty and the available space.
This is illustrated by a recent project for a client in the textile and synthetic fiber production sector, who needed to cool two process tanks, each 60 cm wide with a usable length of 4 meters. Cooling is achieved via plates immersed directly in the tanks through a water-to-water heat transfer process. Cooling water is supplied at 8°C to maintain the process water at a temperature between 20°C and 40°C, depending on production requirements.

Space constraints were carefully evaluated, further complicated by the presence of drain pipes at the bottom of the tanks. Consequently, the plate was positioned on the bottom of the tank floor but raised by a few centimeters, allowing for heat exchange across both sides of the plate. A wide range of industries can benefit significantly from immersion plate heat exchanger cooling solutions—from textiles and electroplating to surface treatments and heat recovery from wastewater.
In parallel, Tempco has indeed developed another application using TCOIL immersion plate heat exchangers for a client in the maritime/port sector. This project applies the same principle used for the textile industry client, but utilizes wastewater as a heat transfer source for winter heating and summer cooling, leveraging a heat-recovery-based cooling solution.
