rate 113 gallon each and every minute per linear foot of pad system ought to be provided to make sure adequate wetting.<\/p>\nAn alternate system runs on the fog or good mist injected into the intake air stream. Although many commercial systems are available, growers can assemble and install their own system using a high pressure piston pump and fog nozzles. The basic components are shown in Fig. 1. A two-stage system controlled by a two- stage thermostat enables more water to be employed on excessively warm, bright days. Temperature settings ought to be 5-10\u00b0F apart.<\/p>\n
Algae development in the pads may become a problem that may reduce the effectiveness of the system and lead to accelerated deterioration of the pads. The addition of an algaecide to the water supply can help in control.<\/p>\n
It really is desirable, especially in hard water areas, to add a wetting agent to the drinking water to obtain more uniform wetting of the pads. A commercial materials or liquid household detergent at the price of 2 tablespoons per 100 gallons can be used.<\/p>\n
Water for the pads should be clean and lower in mineral content to prevent clogging and coating of the pads. A pump, pipes and gutters are accustomed to recirculate the water. A flow rate 113 gallon each and every minute per linear foot of pad system ought to be provided to make sure adequate wetting.<\/p>\n
In the most common cooling system (fan and pad), the fans draw air through wet pads that extend the length of 1 endwall or sidewall. Aspen and coated cellulose are common pad materials that always have life of one to 3 years. Approximately one sq . foot of pad are is necessary for 20 square foot of floor area.<\/p>\n
