Automatic Pressurization Units (APU)

High-performance, intelligent pressure management systems for closed-loop heating and chilled water networks. Vamsy Engineering Co. (VEECO) manufactures them to prevent system pressure drops, air ingress, and pump cavitation.

Reliable Pressure Maintenance & Automatic Water Top-Up

Vamsy Engineering Co. manufactures highly reliable and fully automatic Pressurization Units. In any closed-loop HVAC, heating, or chilled water system, maintaining correct pressure is vital. Our Pressurization Units monitor system pressure and automatically add make-up water to compensate for natural losses (due to micro-leaks, venting, or temperature drops) without manual intervention.

Key Highlighting Points:

🤖 Fully Automatic: Smart pressure-sensor-driven operation.
🛡️ Cavitation Prevention: Keeps pumps safe by ensuring optimal intake pressure.
⏱️ Compact & Enclosed: Saves space over old-style open gravity feed tanks.

Why VEECO Pressurization Units?

Intelligent PLC Controls – Automated pressure detection via digital sensors. Keeps visual status and raises alarms for high/low pressures & pump fault alerts.

Duty / Standby Backup – Options with dual-pump systems (Duty + Standby) with automatic cyclic changeovers for non-stop, failsafe operations.

Energy Efficient – Draws minimal electrical power, running only when pressure declines, decreasing operational wear and energy costs.

Integrated Break Tank – In-built water storage tank with high-quality float valves to ensure a safe air-gap separation from the potable water supply.

Sturdy & Vibration-Free – Robust baseplate construction with vibration isolation dampeners to ensure quiet operation in plant rooms.

BMS Compatibility – Comes ready to integrate with Building Management Systems (BMS) for remote monitoring.

Applications

🏢 Commercial & Industrial HVAC: Keeps uniform pressure in closed-loop air conditioning and chiller networks.

🔥 Hydronic Heating Systems: Safe, continuous water replenishment and expansion protection in boilers.

🏭 District & Facility Heating: Large-scale commercial high-rise buildings and industrial process heat systems.

💧 Chilled Water Networks: Prevents pressure drops to maintain constant liquid temperature in factories.

Quality Testing

At Vamsy Engineering, we don’t just assemble – we verify! Every Pressurization Unit goes through:

Pressure Testing: All pipework & junctions are hydrostatic-pressure tested before dispatch.

Electrical Testing: Full wiring, sensor calibrations, and PLC programming tests.

Pump Run Verification: Verify automated start, stop, and low/high trigger limits under simulation.
