Design and construction of heat exchangers.
This project concerns a CO2 heater and cooler. Heating is done by means of steam and cooling with cooling water. Heating of the supercritical CO2 is necessary to ensure proper dyeing of the textile. After the dyeing process, the CO2 must be cooled back in the CO2 cooler.
After successful lab-scale tests, the customer decided to develop a full-scale waterless dyeing machine for textiles. The process is a breakthrough in the textile world. The current dyeing process uses 125 liters of water per kilogram of textile. By using supercritical CO2, water consumption can be reduced to zero. The CO2 in the machine is recycled and reused for multiple cycles. This technique means the end of unnecessary consumption of precious water and the associated pollution. Especially in the countries where the dye houses are located, this water consumption and pollution is a major problem. Major brands such as Nike, Adidas and Ikea have now rallied behind this technique and the industry is facing a sustainable future.

“As a developer of gas treatment and gas compressor installations, we regularly need equipment that does not fit within the thirteen-in-a-dozen type. We work on a project basis and often have special requirements with regard to design, materials and dimensions for the heat exchangers. In addition, we often have to deal with additional specifications and requirements from our customer. ROBOX can provide this, enabling us to meet the often far-reaching specifications and strict requirements of our customers.
What we especially appreciate about the cooperation with ROBOX is that they are very flexible. This also has everything to do with the customer’s package of requirements. Sometimes the development process takes a long time, the design is changed again or our customers still have additional requirements. ROBOX always responds very reasonably to this and they think along to make the process run as efficiently as possible.
This efficiency is reflected in ROBOX’s entire business operations: communication is correct and adequate, agreements are kept and products are delivered on time. These products are developed with great care and expertise. Exactly what our sector and our customers need. ”
