Tempco has been recently working on several projects involving the construction of custom-designed dry coolers. A special attention is in particular paid to ensure the compliance with the electrical safety regulations for this type of cooling device. In this case, electrical safety becomes an integral part of the dry cooler design.
Air exchangers – or dry coolers – are often seen as ‘simple’ devices: a finned coil with fans that ensure heat dissipation. In fact, getting closer to the actual needs of the systems, requirements immediately emerge that make these systems anything but standard.
A key issue are electrical and ventilation regulations, which vary depending on the type of industry and geographical area of destination:
- explosive environments, which require ATEX fans;
- applications subject to IN METRO regulations, internationally;
- UL compliance requirements, required for North American markets.
These are all situations in which the dry cooler can no longer be considered a standard product, but rather a custom project, designed for the specific needs of the customer and the process.
Tempco’s versatility lies precisely here: a flexible approach that allows us to integrate special fans and motors, complying with various regulations and ensuring maximum operational safety. Because behind what appears to be ‘just a fan’, in reality lies the key to ensure operations of an entire system safely, reliably, and compliant with industry regulations.
