The ordinary cooling towers are difficult to maintain, and their cooling fills are difficult to remove. However, JH’s easy-to-maintain closed circuit cooling towers (The SCT Series) are made of #304 stainless steel and are equipped with an all-in-one detachable design, and thus do not have consumable issue from cooling fill. Besides, one person can complete the maintenance of these cooling towers alone. There is no need to hire a professional technician to do such work, thereby making follow-up maintenance and repair works more convenient. At the same time, the JH cooling towers are closed circuit-type (What is the design principle of a closed circuit cooling tower?), which ensures that your equipment will not encounter scale deposit problems. All you have to do is to regularly maintain the JH Closed Circuit Cooling Towers.
