Critères de conception
The BAC standard BCP0D water treatment system is designed for use with evaporative cooling equipment. The
number and sizing of BCP0D is function of the cooling system design load conditions, expected operating cycle
of concentration (hence water usage), and application for open and closed circuit evaporative cooling
equipment. Ces aspects sont déterminés par un représentant BAC qualifié. Changes in system load which
increase the bleed rate may require an increase in the size of each BCP0D .
Installation et ancrage
The BCP0D should be located as close a s possible to the sump or system interface piping: maximum 7 m
distance.
Pour une distance plus longue, il est recommandé d'installer une pompe de surpression séparée (par d'autres).
The BCP0D is designed to receive water flow at the inlet from pressurized sources, such as the pressure side of
the spray pump or condenser water lines. The pressure at the inlet of the BCP0D should not exceed 60 kPa.
The discharge water from the BCP0D should be returned on a non-pressurized point, preferably the cooling
water sump or the suction side of the system circulating pump (for open cooling towers).
L'évacuation doit être reliée directement à un point de collecte des eaux usées.
The BCP0D can be mounted and supported to the cooling tower panel, to a wall or support structure using a
variety of anchoring methods. When installed outside it is recommended to install the BCP0D above the cooling
tower water level to allow free piping drainage when idle.
The BCP0D is equipped with valves at the inlet, discharge and drain.
1. Les vannes d'entrée et de vidange doivent être maintenues complètement ouvertes pendant le
fonctionnement normal.
2. La vanne de retour peut être étranglée pour réduire le débit d'eau pendant le cycle de mesure.
3. The BCP0D is designed to handle a maximum water pressure of 60 kPa at 55°C.
Exemple d'installation
Câblage électrique
Reportez-vous au schéma de câblage du dossier de soumission.
The BCP0D is suitable for connection to networks of 110V - 230V and 50 - 60 Hz (AC POWER).
The BCP0D panel is pre-wired and only requires a main power supply to the controller BACT 100 .
Une sortie d'alarme générale est également disponible comme indiqué sur le câblage.
