Drive System Accessories

  • Vibration Cutout Switch (Option) — A factory mounted vibration cutout switch is available to effectively protect against rotating equipment failure. BAC can provide either a mechanical or solid-state electronic vibration cutout switch in a NEMA 4 enclosure to ensure reliable protection. Additional contacts can be provided on either switch type to activate an alarm. Remote reset capability is also available on either switch type.
  • Automatic Bearing Greaser (Option) — Automatic bearing greasers come with BAC recommended grease, compatible with all BAC bearings and provide a continuous supply of new grease to eliminate the need for periodic bearing maintenance. Life of the bearing is extended by eliminating under and over greasing problems. Positive displacement pumps allow for mounting up to 30 feet away from the bearing. When the grease pouch is nearly depleted, after three months to a year depending on bearing size, simply replace the pouch.

Cold Water Basin Accessories

  • Standard Mechanical Water Level Control Mechanical make-up valves must operate continuously in the moist and turbulent environment within evaporative cooling equipment. Due to this environment, the operation of the valve must be simple and the valve must be durable. BAC’s high quality mechanical water level control assembly is standard with all units and has been specially designed to provide the most reliable operation while being easy to maintain. This accessory is omitted for remote sump applications.
  • Electric Water Level Control (Option) — BAC’s electric water level control (EWLC) is a state-of-the-art, conductivity actuated, probe type liquid level control. The hermetically sealed EWLC is engineered and manufactured specifically for use in evaporative cooling systems and is equipped with an error code LED to indicate status, including when the water and/or probes are dirty. The EWLC option replaces the standard mechanical make-up valve and includes a slow closing, solenoid activated valve in the make-up water line to minimize water hammer. EWLC is recommended when more precise water level control is required and in areas that experience sub-freezing conditions.
  • Basin Sweeper Piping (Option) Basin sweeper piping is an effective method of eliminating sediment that may collect in the basin. A complete piping system, including nozzles, is provided in the basin to connect to side stream filtration equipment (provided by others). For more information on filtration systems, consult  the Filtration Guide.
  • Low and High Level Alarm Float Switches (Option) Low and high level alarm float switches are available to provide added control to your equipment operation. Level alarms can alert operators to an abnormal operating condition to ensure the highest system efficiency with minimal water usage.
  • Basin Heaters (Option) Evaporative cooling equipment exposed to below freezing ambient temperatures require protection to prevent freezing of the water in the cold water basin when the unit is idle. Factory-installed electric immersion heaters, which maintain 40°F (4.4°C) water temperature, are a simple and inexpensive way of providing such protection.

Air Discharge Accessories

  • PCD Hoods and Insulation (Option) The innovative design of BAC closed circuit cooling towers results in a low heat loss when the unit is idle. When additional heat loss prevention is desired, factory mounted PCDs with stainless steel linkages and damper actuators can be provided. The motor actuators are easily accessible. The addition of factory mounted insulation to the hood and/or coil casing further reduces the heat loss by minimizing losses due to conduction. Per ASHRAE 90.1-2010 either an automatic 3 way valve or PCDs are required on closed circuit cooling towers used on heat pump applications in climate zones 3 through 8.

  • Fan Cowl Extensions (Option) Fan cowl extensions allow for unobstructed airflow on the discharge side, which help ensure that the units are providing maximum capacity. When closed circuit cooling towers cannot be located above adjacent structures, fan cowl extensions will be necessary so that discharge air flows out of the tower properly and is not circulated back toward the air intake by the combination of wind pressure and adjacent structures.

Access Options

  • Motor Removal System (Option) — All motor removal system options include davit arm(s) to facilitate motor replacement.
  • Modular External Platforms and Ladder Packages (Option) Every modular external platform is pre-assembled and pre-fitted at the factory to ensure that every component will fit and function exactly as described. The platform is rigged easily in the field with minimum fasteners and drastically reduces the time required for rigging external access platforms.
  • External Ladder (Option) The PFi can be furnished with an inclined ladder – a 75° angled ladder – extending from the base of the unit to the access door, providing safe access with minimal space requirements. All components are designed to meet OSHA requirement.
