Our Air-cooled Heat Exchangers are the preferred solutions for applications which require a great deal of customisation. Mangalam Techno has forced and induced draught systems with design pressures up to 160 bars, comprehensive process control options and various kinds of finned tubes. We have a team of experienced engineers that assist you throughout the design stage, to ensure that all possible challenges are taken into account and their solutions found in the design stage itself. Design features
A typical face velocity for the air flowing across the tube bundle is 3 m/s. Higher air flows increase both the heat transfer coefficient and the mean temperature difference, thereby reducing the surface area required, but at a higher power consumption. Increased airflow and power also mean greater fan noise, which is an increasingly important factor.
The choice of design ambient temperature is the most critical factor affecting the size of an ACHE. A dry bulb temperature that is not exceeded for 95% of the year is the usual choice, accepting that there may be a cooling shortfall on the hottest days.
Small independent ACHEs can be quite expensive, and it is therefore normal practice to install two or more small units in a shared fan bay. This is particularly useful when several exchangers are to be mounted in a bank with a common tubelength.
