As their name implies, watercooled chillers use water to absorb heat from the chiller and disperse it through a cooling tower, as opposed to aircooled chillers and RTUs, which disperse heat only by using aircooled condensor coils.
A "shop built" tower is a smaller tower that is factory assembled and shipped complete ready for use by the customer. The HVAC market is the primarily user of these types of towers. Standard or custom shapes can be used in construction of this type of tower.
Cooling Tower Fan Housing Cleaning and Maintenance The fan housing should be carefully scrubbed and disinfected. This is a common problem area; chemical treatment cannot always prevent bacteria from getting a strong hold in these areas.

It must also provide the energy head necessary to raise water from a low to a higher static head level.
Cooling tower selection and performance is based on water flow rate, water inlet temperature, water outlet temperature and ambient wet bulb temperature. Ambient wet bulb temperature and its affect on performance is the subject of this article.
Cooling Tower authorSTREAM Presentation. WATER PUMPS: WATER PUMPS Pump must have a shaft seal Most pumps are made from cast iron Most centrifugal pump impellers are made of bronze The eye of the impeller must be under water during startup If the pump is located higher than the sump, the pump must be filled with water before starting Whirlpool action in the pump is called vortexing
FM Approved cooling towers and towers equipped with FM Approved fill materials and FM Approved components are considered to be either noncombustible or of limited combustibility (equivalent to Class 1) such that they do not require automatic sprinkler protection.
conventional wet cooling tower is added to the system. Water from the tower takes heat away from either an added surface condenser or from the hot coolant. The tower and water streams are sized to handle about 30% of the overall heat rejection load from the plant. The other
NOTES: Cooling tower maintenance is more than simply biological monitoring, a maintenance plan also has to address other issues such as the condition of the equipment, condition of the mist eliminator, general corrosion, conductivity, sedimentation, control mechanisms, etc.
THE BASICS OF COOLING TOWER WATER TREATMENT The purpose of a cooling tower is to remove the heat generated by an HVAC system (cooling of compressor refrigerant and heat generated by the compressor itself).
Star Cooling Towers supplies a wide range of cooling tower products and services to utilities, process and industrial customers. They have come to rely on Star Cooling towers' reputation for quality, value and superb customer service.
A cooling tower should be constructed so that this backflow of exhaust air into the tower and its mixing with the suction air are avoided. During summertime the backflow is harmful because of reduced cooling capacity and during wintertime there is the risk of icing.
