Deaerators

Advantages of the UDAV Deaeration Unit

• Mobility - can operate in any mode - vacuum mode, atmospheric mode, and high-pressure mode (up to 6 atm).
• Wide operating range from 0 to 120% of nominal capacity.
• High quality of deaerated water - oxygen content not exceeding 20 µg/l (If higher quality requirements are specified, it is possible to achieve guaranteed oxygen content not exceeding 7 µg/l).
• Compact size due to low metal consumption (small and lightweight).
• High efficiency due to high specific productivity (high efficiency).
• Absence of bubbling significantly reduces corrosion of deaeration tanks (increases tank lifespan).
• System stability due to the absence of bubbling in the deaeration tank (no water hammer).
• Easy maintenance as there are no parts that fail (no need for preventive maintenance or annual repairs).
• Safety - UDAV deaeration units are fully automated (minimizing human error).
• Compactness. Possibility of modular design (ease of installation and commissioning).
• Cost-effectiveness as UDAV units are tailored to each project individually at all stages (design, engineering, and production), whether for new installations or reconstruction of any type of unit (traditional DA, etc.). This approach allows for maximum utilization of existing equipment and implementation of only what is necessary (nothing extra).
• Wide applicability of UDAV - ensuring high-quality deaeration under any technical conditions and requirements of the facility (nothing is impossible).

Unit Configuration

1. If the task is to reconstruct an existing deaeration unit, the configuration is determined after a detailed analysis.

2. If a new installation is planned, the configuration is determined after reviewing all your requirements.

Below are the most common configurations:

For operation in atmospheric mode:

Name	Centrifugal-Vortex Deaerator	Droplet Disperser	Droplet Deaeration Tank	Surface Vapor Cooler
Designation	DCV	DK	BKD	OV

Automation

Upon request, our company can equip the UDAV atmospheric-vacuum deaeration units with a control panel - SCU UDAV.

Control Panel for Atmospheric-Vacuum Deaeration Unit SCU UDAV

TU 4236-004-71850392-2011

SCU UDAV is designed to automate the operation of the UDAV deaeration unit by collecting, processing, and distributing information from various sources (pressure sensors, temperature sensors, etc.) for further processing and generating control actions on the controlled object (regulator at the unit inlet, steam regulator, etc.).

SCU UDAV is a wall-mounted cabinet with a protection class corresponding to the technical specifications. The cabinet is cooled by forced ventilation. Power supply is 220V. It can be equipped with an uninterruptible power supply with a battery. Power and connection to external automation devices are provided through terminal connections located at the bottom of the cabinet. Cable entry is from the bottom through a designated entry port.

Functionally, SCU UDAV consists of a programmable logic controller (PLC) and input/output modules. The PLC is programmed in one of the IEC 61131-3 languages in the CoDeSys programming environment. The input/output modules and software are configured for the assigned tasks using configuration programs supplied with the equipment.

The main technological screen is "General Scheme".

The panel has high data transfer speed and rendering of interactive graphical display objects, performs complex animations and multi-page switching without delays. It supports CANopen, BacNET/IP, and MPI/PPI protocols for connecting to multiple devices. Due to the aluminum casing, the panel has high corrosion resistance and an extended lifespan.

There are several easy-to-use technological screens (TS) necessary for setting up and monitoring the current process of the UDAV deaeration unit.

SCU UDAV should be operated in specialized departments at the customer's facilities. The end users should be employees of the specialized departments of the customer's facilities.

Pump Station

Control Cabinet for Pumps UDAV TU 3431-005-71850392-2012

The cabinet is designed to control pump motors, typically in "one running, one standby" mode. The cabinet can operate in both manual and automatic modes.

Pump rotation by time is possible.

The Pump Station Control Cabinet (PSC) is a wall-mounted cabinet with a protection class corresponding to the technical specifications. The cabinet is cooled by forced ventilation. Power supply is 380V. Power and connection to external automation devices are provided through terminal connections located at the bottom of the cabinet. Cable entry is from the bottom through a designated entry port. Functionally, PSC consists of a frequency converter, programmable relay, and power switching devices. The frequency converter and programmable relay are configured for the assigned tasks using programs supplied with the equipment.
