Conductivity probe SPS21
The ADCATrol SPS21 conductivity probe is typically used in steam applications to measure the conductivity of superheated boiler water, condensate or feedwater. The probe is used in conjunction with an ADCATrol BCS controller and a VPC series TDS blowdown control valve.
Water contains impurities in the form of dissolved solids and solids in suspension, whose concentration increases during vaporization. Water treatment can reduce impurities to a certain degree, however these are not completely eliminated and, in certain conditions, might even increase. As steam production starts, there is an undesirable increase in boiler water TDS (Total Dissolved Solids) concentration. If not taken care of, the high concentration can lead to problems such as water foaming, reduced boiler performance and wet steam. Contamination of the steam may occur, resulting in system damage further ahead, such as corrosion, scaling, salt incrustations on heat transfer surfaces, among other problems.
Furthermore, the high concentration is harmful and is not acceptable in applications where steam is used for treatment of food, drinks and in sterilization processes.
For these reasons, a certain amount of boiler water must be discharged continuously or periodically to ensure TDS concentration is kept within the recommended parameters.
- Compact stainless steel construction.
- IP 65 protection.

Tds blowdown control valves VPC 26S
When a steam boiler is in operation there is continuous evaporation of boiler water which causes an undesirable increase in TDS (Total Dissolved Solids) concentration. A typical problem that results from this is water foaming, which leads to reduced boiler performance and wet steam. Furthermore, dissolved and suspended solids will carry over into the steam lines, contaminating valves, tubes, heat exchangers and steam traps, leading to corrosion, scaling and erosion. For these reasons, a certain amount of boiler water must be discharged continuously or periodically to ensure TDS concentration is kept within the recommended parameters.
The ADCATrol VPC26 is a control valve specially designed for this purpose and features a multi-stage trim to progressively reduce the energy of the fluid. This makes it ideal for discharge of boiler blowdown at high differential pressures where flashing is a concern.
The valve is suitable for both continuous and on/off TDS control via a PA series reverse action pneumatic actuator or AV series fail-safe spring return actuator.

Heating and Deaeration Boiler Feed water
Atmospheric semi – deaerators ADG
The ADCATherm atmospheric semi-deaerators are designed to heat boiler feed water and to reduce oxygen and carbon dioxide (oxygen values in the feed water of less than 1,6 mg/L can be achieved). Remaining oxygen can be completely removed using oxygen scavenging chemicals.
Basically, the complete system consists of a storage vessel, a deaeration head section and a vent.
- Prevents energy wasting.
- Easy to install.
- Can be installed on new or existing systems.
- Reduces the flow of flash steam from the vessel venting pipe.
- Long life expectancy.

- ISO or NPT threaded sockets.
- Different connections on request.
- Carbon steel with internal stainless steel components.
- Deaerator head – vertical installation.
- Storage vessel – cylindrical horizontal design.
- Final dimensions and connections according to the drawing supplied after order confirmation.
Hot return condensate is injected in the bottom of the storage vessel using an adequate sparger pipe and softened make-up water is introduced in the deaerator head to be heated by a contact cascade flash steam heating system (counter-current flow) coming from the vessel. A part of the dissolved gases is liberated from the water at this point, and then to the atmosphere, trough the flash steam vent line.
The semi-deaerated water then falls to the storage vessel below, where a steam injection system will provide an additional deaeration.
The complete unit is supplied, including all the necessary instrumentation for temperature and level control, to be described in our offer, depending on the operation conditions (see Table 1).
Flash condensing heads FCD
The ADCATherm flash condensing heads are designed to promote energy efficiency on new or existing systems.
Mixing the flash steam with the boiler make-up water allows the energy within the flash steam to be fully absorbed into the water and therefore reduces energy waste that normally occurs from the discharge of flash steam through a vent.
The main advantages over some traditional systems are that it is possible to make most of the piping connections in a single and compact mixing unit and a greater heat recovery efficiency can be achieved.
This mixing unit includes the following fluid connections:
- Cold make-up water;
- Condensate return;
- Re-circulating feedwater;
- Vacuum breaker and vent connection;
- Optional connections for flash steam from a TDS (Total Dissolved Solids) heat recovery system.
The mixing unit includes the necessary baffles, spray nozzle, water injector pipe, etc., in order to guarantee the high mixing energy efficiency. The water is finally mixed in the vessel as it passes through an immersion tube, which ensures a quiet operation.
The feedwater is re-circulated using a low power re-circulating pump which will improve thermal efficiency by reducing the temperature stratification.
Additional equipment can be used to improve energy efficiency and accurate control. ADCATrol control valves, steam injectors, exhaust heads and many other items are available from an ADCA supplier.
Since each plant has particular requirements we suggest that a local ADCA distributor is contacted for layout discussion and equipment selection.

Returning condensate and softened make-up water are introduced in the deaerator dome to be heated by a contact cascade steam heating system (counter-current flow). Most of the dissolved gases are liberated from the water at this point, and they are released to the atmosphere trough the flash steam vent line.
The deaerated water then falls to the storage vessel below, where a steam blanket ensures that no gases are reabsorbed.
A sparger pipe is installed inside the tank, at the bottom level, providing the necessary heating energy. A second low pressure steam supply may also be necessary.
The complete unit is supplied including all the necessary instrumentation for temperature, pressure and level control, to be described in our offer depending on the operation conditions (see Table 1).

This device can be used for boiler water analysis as well as other types of sampling or cooling applications compatible with the materials of construction.

Blowdown Expansion Vessel
Blowdown expansion and cooling units BEX
The BEX blowdown expansion and cooling tank is used in modern boiler rooms to cool the blowdowns of steam boilers before they are discharged to the general drainage system.
The boiler blowdowns are discharged into the BEX expansion tank at atmospheric pressure and are cooled by the supply of cold water through a thermostatic control valve which is controlled by a thermostat mounted inside the tank.
If the generated flash steam cannot be recovered or is discharged into the environment, an additional water spray system can be installed inside the BEX tank.
This is mounted on top of the unit and can be controlled directly by another thermostat or by the same control that activates the automatic sludge purge.
- Prevents thermal contamination
- Overflow siphon tube
- Easy to install

Blowdown expansion vessels BV
The BV expansion and blowdown cooling tank is used in modern boiler rooms to cool steam boiler blowdowns before they are discharged to the general drainage system. The boiler blowdowns are discharged into the expansion tank BV at atmospheric pressure and are cooled by the supply of cold water through a thermostatic control valve which is controlled by the corresponding thermostat mounted inside the tank. If the flash steam that is generated cannot be recovered or is discharged into the environment, an additional water spray system can be installed inside the BV tank. This is mounted on top of the unit and can be controlled directly by another thermostat or by the same control that activates the automatic sludge purge.
