Frequently asked questions

What's special about the Flush type cosmetic applicator?

The Flush type sprinkler head sticks out a little from the ceiling, and we can see that it is a completely installed fire protection system with an easy eye. And, it is faster to install than the Concealed type.

How do we calculate the pressurization & vacuum system?

You just need to provide PGTECH with the following information, we will give you a solution for the pressure regulation and vacuum air separation system:

Supply line temperature
Return line temperature
System working pressure
System static pressure
Total amount of water in the system
The height of the equipment location and the height of the building
Total kW of Chiller/Boiler

To make the ceiling beautiful and aesthetic, which type of sprinkler head do we usually use?

We can use Concealed type or Flush Type ceiling nozzles.

How to calculate the deaeration filter to suit the system?

Usually, the deaeration filter will be calculated based on the flow value of liters/second (liters/minute). However, it can also be calculated based on pipe size for convenience while still promoting the effectiveness of this solution.

Is it necessary to stop the system to clean Flamco's Dirt and Air Separator with Smart technology?

No need. The system still operates continuously, and the operator only needs to turn the sediment discharge valve to remove all the debris in the filter.

To remove scale stuck to pipes and machinery for Heating and Cooling systems, what effective technology is used?

We can use Flamco Netherlands' Dirt and Air Separator or Dirt Separator Smart technology to remove all dirt from the water source effectively.

Can ActivFlo be installed in large and circulating systems such as Heating and Cooling systems?

Absolutely OK. It is effective for HVAC and plumbing systems. Even large systems of hundreds of m3/h are difficult for other systems to handle.

Is there any method that does not require chemicals, does not require reconstituted salt and cation granules, does not use a RO system and still effectively treats hard water?

UK's ActivFlo technology is the solution that meets the above criteria. Just install a compact device that requires no maintenance and can operate for decades.

Is the grease separator and sludge separator required for fat waste treatment in commercial and industrial kitchens mandatory according to environmental laws?

Is mandatory. In addition, investors need to pay attention to installing grease traps for kitchens to avoid clogged drains, causing nuisance and instability in kitchen operations.

Is Oil Separator required for machinery maintenance warehouses, garages, and gas stations?

Have. It is a mandatory requirement to have a waste oil separation system for areas where oil spills are released into the environment. Requires installation of Oil Separtor system and oil separator tank.
