Features & Benefits
Berg Chilling Systems Inc. offers complete flexibility in pumping assembly designs from dimensions to capacity for any industrial application. Reservoirs are available in mild steel, stainless steel, plastic all mounted on a structural steel base with banding for additional long term structural support. Single pump systems to multiple pumps complete with a magnitude of options such as headers, detached pumping skids for ease of shipment and installation.
• Central control panels – PLC controlled
• Fully valved headers
• Variable frequency drives
• Mounted auxiliaries – chemical treatment, filters, etc.
• Expansion/closed mix tanks for compete closed circuit systems
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 cooling tower(s) for maximum efficiency.
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 cooling tower operation.

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 (Programmable 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.
Berg offers complete flexibility in pump / tank assembly designs to customize both dimensions and capacity for any industrial application. Reservoirs are available in mild and stainless steel, mounted on a heavy structural steel base, and have steel banding for additional structural support for the reservoir.
Pumps can be single-end mounted or dual-end mounted. Single pumps to multiple pumps complete with pipe headers are available. For large pump / tank Assemblies, the pump assembly can be designed to be separate from the reservoir for installation and shipping constraints.
