What Is the Bollfilter 4.36.2 Different Pressure Contact Indicator?
The Bollfilter 4.36.2 is a pressure contact indicator used to measure differential pressure over filter elements. In simple terms, it calculates the pressure difference before and after the filter.
This assists operators in identifying the condition of the filter element. If the pressure difference is too high, it’s an indication that the filter is clogging and requires cleaning or replacement.
The unit provides an electrical or visual indication when a predetermined pressure limit is reached, allowing for easier maintenance on a timely basis.
Key Features
Following are some of the key features of the Bollfilter 4.36.2:
Accurate Monitoring: Monitors pressure difference with high precision.
Early Warning System: Provides signals when the filter is blocked.
Robust Design: Designed to withstand harsh marine and industrial conditions.
Easy Integration: Integrates easily with existing Boll & Kirch filter systems.
Compact & Dependable: Occupies less space while offering utmost use.
Why Differential Pressure Monitoring Matters?
Filters are invaluable in keeping sludge, contaminants, and particles away from critical equipment. Filters inevitably become clogged with time—this is natural. But failing to know when a filter must be maintained can result in:
- Lower system efficiency
- Increased energy use
- Possible system failures or shutdowns
With the use of a differential pressure contact indicator such as the Bollfilter 4.36.2, proactive maintenance is possible. That equates to less time lost due to downtime, less money spent, and more equipment longevity.
Uses of the Bollfilter 4.36.2
This contact pressure indicator is often applied in:
Marine Engines: In order to safeguard against contaminated lubricants or fuel.
Industrial Processing Units: Where hydraulic or lubrication systems are essential.
Oil & Gas Equipment: Ensuring clean flow of fluids in pipelines and machinery.
Power Plants: Where clean water and oil circulation is critical to operations.
Wherever Boll & Kirch filters are used, the 4.36.2 indicator can be included to enhance real-time monitoring and filter reliability.
How It Works
Normal Operation: Filter is clean, pressure difference is minimal. No action required.
Clogging Begins: Pressure before the filter rises, pressure after it falls.
Set Point Reached: The unit senses the pressure difference has surpassed the set threshold.
Signal Sent: A contact is triggered—either making or breaking an electric circuit, or sending a visual signal.
Maintenance Alerted: Operators are notified it’s time to clean or replace the filter.
This process enables intelligent maintenance scheduling instead of repairative action.
