Heat exchanger
MERUS stops or reduces the process of fouling in a heat exchanger. Details and our experience from the field see at the table below. The design of a heat exchanger and its hydro dynamic quality are responsible, how fast and how strong fouling take place in a heat exchanger. Tubular heat exchanger have in general a better hydro dynamic desing, because mostly a laminar flow inside is achieved. The somewhat less expensive plate heat exchanger have due to the design, inside areas where there is less flow. In these areas with poorer flow, the fouling starts first and layers of calcium or other mineral start to build. Starting from this parts, the heat exchanger start to close and finally has to be cleaned. Integrated heat exchangers (e.g. cooling in a motor) have very often an unfavourable flow characteristic and has to be cleaned most often. Merus is world wide, successfully used in hundreds of heat exchangers. The major applications are heat exchanger in cooling loops, heat exchanger for compressors, heat exchanger for cooling and airconditioning systems, as well as integrated heat exchanger in mold forms, machines and motors.

The above shown values are valid for water with not more than 1500 TDS* and temperatures until 100° Celsius. At higher TDS rates the success rates lower accordingly. Fouling caused by product or remaining of product, are as well able to treat by Merus, but these has to be discussed separate. *TDS - Total Dissolved Solids

Not only influenceable parameter such as the water quality and temperature in a heat exchanger, are responsible for fouling or scaling inside a heat exchanger. As well not direct influenceable parameter, as details of construction of a heat exchanger, the design of the water loop (material, open/closed system, blow down) have a significant influence on cleaning cycles
