External Service Platforms

External Platform at Louver Face With Ladder and Safety Cage

Every external platform is preassembled and pre-fitted at the factory to ensure that every component will fit and function exactly as described. The platform will ship secured in the basin and attach quickly in the field with minimum fasteners. Platforms, ladders and cages can be added at the time of order or as an aftermarket item.

Safety Gates

Safety gates are available for all handrail openings. All components are designed to meet OSHA requirements.

Ladder, Safety Cage, Gate and Handrails

In the event the end-user elects to provide access to the fan deck, CXV-T models can be furnished with ladders extending from the top of the unit. Safety cages, safety gates, fan deck extensions, and handrail packages are available. All components are designed to meet OSHA requirements.

Note: For CXV-T models, partial or full grating above the coil air intake is recommended with this option.

Internal Service Platforms

For access to the motor and drive assemblies on most CXVB and CXV-T models, an internal ladder and upper service platform with handrails is available. Safety gates are available for all handrail openings. All components are designed to meet OSHA requirements.

Vibration Cutout Switch

A factory mounted vibration cutout switch is available to effectively protect against equipment failure due to excessive vibration of the mechanical equipment system. 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.

Basin Heaters

Basin Heater

Evaporative condensers which are 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.

Heater kW Data

Note: The table data is based on 460V/3 phase/60HZ power and standard, single-cell configuration

Electric Water Level Control Package

Electric Water Level Control Package

The electric water level control replaces the standard mechanical make-up valve when a more precise water level control is required. This package consists of a conductance-actuated level control mounted in the basin and a solenoid activated valve in the make-up water line. The valve is slow closing to minimize water hammer.

Extended Lubrication Lines (Standard)

Grease Fittings at the Access Door and Bearings With the Extended Lubrication Line Option

Extended lubrication lines are available for lubrication of the fan shaft bearings. Grease fittings are located inside the plenum area next to the access door.

High Temperature Fill

Optional high temperature fill material is available for high spray water temperatures up to 135˚F (57.2˚C).

Top Mounted Sunlight Shades

The corrosion resistant shields are mounted above the spray distribution system and helps to smooth the airflow into the coils for optimum thermal performance. They also block sunlight and reduce the potential for algae growth.

Basin Sweeper Piping

Basin Sweeper Piping

Basin sweeper piping provides an effective method of preventing debris from collecting in the cold water basin of the unit. A complete piping system, including nozzles, is provided in the unit basin for connection to side stream filtration equipment (by others).
