Inclined Ladders

Inclined Ladder

In the event the owner requires access to the mechanical plenum, but does not require a working surface, the PC2 can be furnished with an inclined ladder – a 75º angled ladder – which extends from the base of the unit to the access door, providing safe access with minimal space requirements. All components are designed to meet OSHA requirements.

Pre-Assembled Platforms, Ladders & Safety Gate

Modular external platforms are pre-assembled at the factory to ensure that every component will fit and function exactly as described. The platform will attach quickly in the field with minimal fasteners. Platforms can be added at the time of order or as an aftermarket item. Safety gates are available for all handrail openings. All components are designed to meet OSHA requirements.

Pre-assembled Platform and Safety Gate

Basin Level Service Platform, Ladder, Saftey Cage, and Gate

For external service, a basin level platform can be added to the evaporative condenser when the unit is purchased or as an aftermarket upgrade. Ladders, safety cages, and safety gates are also available. All components meet OSHA requirements.

Vibration Cutout Switch

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

Evaporative condensers 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/

Single Point Wiring

BAC offers the option for single point wiring on PC2 Evaporative Condensers. Single point wiring decreases installation time by routing wires from motors (fan and pump) and options such as vibration cutout switch, electric water level control and basin heaters in UL-listed conduit to a stainless steel NEMA 3R electrical box.

Electric Water Level Control Package

Electric Water Level Control

The electric water level control replaces the standard mechanical make-up valve when 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.

Basin Sweeper Piping

Basin Sweeper Piping

Basin sweeper piping is an effective method of eliminating sediment that may collect in the cold water basin of the unit. A piping system is provided for connection to side stream filtration equipment (by others).
