As the technology of air cooler manufacturers becomes more and more mature, Products have made great improvements in both performance and appearance. Evaporative air cooler hosts not only have plastic shell hosts but also stainless steel shell hosts. In the past, there was only one material. Then the customer has no choice. Now that there are diversified choices, the customer is even more entangled. Which is better and more durable, the plastic shell or the stainless steel shell host?

Stainless steel has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; it has good hot workability such as stamping and bending, and no heat treatment hardening Phenomenon. It is resistant to corrosion in the atmosphere. If it is an industrial atmosphere or a heavily polluted area, it needs to be cleaned in time to avoid corrosion. The host with a stainless steel casing must keep the environment dry when in use to prevent the machine from rusting and corroding.

Engineering plastics can be used as engineering materials and plastics that replace metal in manufacturing machine parts. Engineering plastics have excellent comprehensive properties, such as high rigidity, low creep, high mechanical strength, good heat resistance, and good electrical insulation. They can be used in harsh chemical and physical environments for a long time and can replace metals as engineering structural materials. , but the price is more expensive and the output is smaller. Different manufacturers have different material requirements for air cooler body shell. So some air cooler shell will break after 2-3years, while some air cooler can work more than 10years.

In fact, small air volume air cooler  use plastic casings. large air volume industrial evaporative cooler use stainless steel casings, because the large air volume host itself is heavier. If it is installed externally at high altitude, The host must be fixed very well. A slight instability will cause a series of safety hazards. Therefore, most hosts with large air volume will be installed on the floor. Only the protection of the stainless steel shell can make the installation of industrial evaporative air cooler easier and Better. then why do small air volumes use more plastic casings? The reason is actually very simple. If the host with a small air volume uses a plastic casing, the weight of the host itself will be reduced. Generally, it is installed on the side walls and roofs, and the installation is stable and safe. so this multiple-choice question is not difficult to answer. It depends on your own installation design plan and what your requirements for the host are. If you just look at From the perspective of durability, in fact, whether they are plastic or stainless steel, they are very durable.
