Multiple pumps configured on a double-ended tank set or modular detachable pumping for shipping larger tanks

A Berg Double Pump Tank System incorporates multiple pumps with a baffled holding tank. The chiller pump (usually the smaller one) circulates water / glycol from the hot side of the tank to the chiller module(s) and back to the cold side of the tank. This pump ensures constant flow and pressure required by the chiller(s) for maximum efficiency, as well as less chance of freeze-up due to the low flow condition. The process pump (usually the larger one) circulates the chilled water from the cold side of the tank to the process machines and other users. This pump is designed to match both flow and pressure required by the varying process load without affecting the chiller operation.

Frame manufactured from heavy gauge structured steel tube with welded construction.
Tank models manufactured from heavy gauge stainless steel.
Tank cover manufactured from stainless steel and supplied in sections for ease of removal and access (Covers are optional).
ALL tanks have baffled compartments if required.
Make-up float valve.
Tanks are structurally supported around top and sides as required.
Tank and surrounding pipe are insulated in high grade insulation material for many years of durability and energy conservation or efficiency losses.

All pump starters are panel mounted on the side of tank or remote panel and are pre-wired to the pump motors. Starters can be controlled with manual Stop / Start switches and indicator lights or HMI ( Human Machine Interface ) type Logic Controller. Motor circuits are protected with premium quality overload protection.

Double Y-Strainer and Pressure Alarm

BERG’s unique system gives complete protection to water circulation equipment with absolutely no down-time. When water pressure across strainer drops to a selected critical level, the alarm and light are actuated. By manually switching to a secondary filter line, the original filter or strainer may be cleaned while maintaining circulation.

Central Control Electrical Panel

A custom electrical control panel allows one point hookup and may include;

HMI ( Human Interface Device ) touchscreens
PLC ( Programable Logic Control )
SCADA ( Supervisory Control And Data Acquisition ) Communication Systems
24/7 alarm reporting to beepers or cell phones

All pump starters, fuses, disconnect, control voltage transformer, run and fail lights, are housed in a common NEMA RATED panel.

Central Thermostat Control System

This system is used to control chiller units in a multiple central chilling system. The temperature controller is located at the BERG tank and senses the process water temperature. The process water temperature is maintained by cycling the chiller units.
