Vibration Cutout Switch

HXV_VCS

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 reliable protection. Additional contacts can be provided on either switch type to activate an alarm.

Basin Heaters

Although most HXV units will operate dry in the winter, basin heaters are available for freeze protection when required. Basin heaters 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.

Electric Water Level Control Package

FXV_EWLC

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.

Flow Control Package

A flow control package is available to provide maximum plume control and water savings. This package consists of a temperature sensor, a 3-way flow control valve arrangement with actuator, and all connecting piping. 3-way flow control valve arrangement shown below for single prime surface and double prime surface coil connections.

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.

Air Inlet Screens

Mesh screens can be factory-installed over the inlet louvers to prevent debris from entering the unit.

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 tower. A complete piping system, including nozzles, is provided in the tower basin for connection to side stream filtration equipment (by others).

Equipment Controls

BAC control panels are specifically designed to work seamlessly with the HXV and provide maximum water savings. The panels are designed to control the spray water pump, the modulating flow valve and the fan motors. For more information, please contact your local BAC Representative.
