The PRESSCON expansion system prevents rust, monitors the water level, and keeps the empty portion of the buffer tank pressurised (blanketed) using nitrogen.

The PRESSCON expansion systems are specified differently for:

• Horizontal storage tanks (HORNIT systems).
• Vertical storage tanks (VERNIT systems).

The safety goals of PRESSCON expansion system are:

• The prevention of corrosion / oxidation.
• Keeping pressure on the heating or cooling system.
• Monitoring of the water level.

Operation / purpose of the expansion system

Our expansion systems use nitrogen as the inert gas of choice for regulating the pressure and effectively blanketing water buffer tanks for both large scale heating or cooling systems.
The nitrogen is generated using our proprietary nitrogen generators, the most energy efficient nitrogen generators on the market.
Nitrogen production is realised by channeling filtered compressed air through a bed of carbon granules (carbon molecular sieve) in the nitrogen generator. The oxygen molecules are absorbed by the carbon granules leaving (almost) pure nitrogen behind. Our units use the most efficient method of producing the nitrogen, which is our proprietary High Pressure Swing Adsorption technique (HPSA-technique)
This new technique is based on the PSA technique completely redeveloped by PRESSCON so that it does away with the main disadvantages of the traditional PSA systems.

Effectively our HPSA nitrogen production units use less energy for production, have a longer use life for the carbon molecular sieve and can produce nitrogen gas with a purity of up to 99,9997%.

The expansion systems can be applied in two different ways.

  • The VERNIT systems provide for regulating the pressure of the nitrogen blanket and monitors the water level in the vertical heat storage tank. Also, it can, if desired, regulate the water level.
  • The HORNIT systems provide for the regulation of the total system pressure and monitors the water level in the horizontal heat storage tank.

PRESSCON also delivers and installs all necessary pressure and safety valves, pressure measurement equipment, oxygen level measurement equipment and compressed air installations that might be required in large scale heating or cooling systems.

Advice and custom solutions

All our products are designed, built and tested in our own factory in Honselersdijk and are characterised by innovation, efficiency and quality.
With both design and production being done in-house, our organisation and products have a high level of flexibility.
This enables us to build and deliver custom installations for the specific challenges and requirements of each project, that go beyond our standardised product line-up.

After Sales:

We offer various maintenance models on the basis of an hourly rate or in the form of a maintenance contract, both within the Netherlands and internationally.
We’ve strived to constantly perfect our product design, in order to simplify maintenance operations and we also provide thorough documentation and trainings for customers that wish to do maintenance themselves.
With our 24/7 service department, we support our customers day and night in case of malfunctions. [/column_2]
