Basin HeatersCooling towers exposed to below freezing ambient temperatures require protection to prevent freezing ofthe water in the cold water basin when the unit is idle. Factory-installed electric immersion heaters, whichmaintain +40°F (4.4°C) water temperature, are a simple and inexpensive way of providing suchprotection.Heater kW Data0°F (-17.8°C) Ambient Heaters-20°F(-28.9°C) Ambient HeatersModel NumberskW per HeaterkW per Heater<strong>PT2</strong>-0412A 6 6<strong>PT2</strong>-0709A 6 8<strong>PT2</strong>-0809A 8 10<strong>PT2</strong>-1009A 8 10<strong>PT2</strong>-0812A 10 12<strong>PT2</strong>-1012A 10 14<strong>PT2</strong>-1212A 12 16Note: The table data is based on 460 Volt/3 phase/60 Hz power and standard, single-cell unit configurationCooling TowersElectric Water Level Control PackageThe electric water level control replaces the standard mechanical make-up valve when more precisewater level control is required. This package consists of a conductance-actuated level control mounted inthe basin and a solenoid activated valve in themake-up water line. The valve is slow closing tominimize water hammer.High Temperature FillIf operation above 140°F (60.0°C) is anticipated,an optional high temperature fill material isavailable which increases the maximum allowableentering water temperature to 150°F (65.6°C).Factory Mutual Approval<strong>PT2</strong> Cooling Towers are available with FactoryMutual (FM) Approved construction as an option.Electronic Water Level Control...because temperature matters D72
