Nitrogen solutions for the greenhouse horticulture industry

In modern greenhouse horticulture, the quality and resilience of your crop depend on the reliable operation of essential systems such as irrigation water supply, heating installations, buffer tanks, climate-related installations and pressurised networks. A single malfunction can directly affect plant growth, stress levels and production continuity.

Growers therefore require installations that are protected against oxygen ingress, corrosion and pressure fluctuations.

In addition to applications for pressure maintenance and plant stability, Presscon has also developed the BPC system: a ULO solution for pest control. This system is used in enclosed spaces, such as climate chambers and storage areas.

With over 25 years of experience in greenhouse horticulture, Presscon is a trusted innovation partner for growers who want to improve system reliability and crop quality through proven nitrogen-based solutions.

How Presscon’s nitrogen solutions support greenhouse processes

Presscon applies High-Performance Pressure Swing Adsorption (HP-PSA) technology to produce nitrogen on-site, exactly at the purity and capacity your installation requires. During this process, compressed air passes through Carbon Molecular Sieve (CMS) beds that bind oxygen molecules, resulting in a continuous supply of nitrogen for applications such as buffer tank pressure control.

The generated nitrogen displaces oxygen in the buffer tank and maintains a stable pressure above the water level. This reduces corrosion risk and pressure-related disturbances within the installation.
By combining on-site nitrogen generation with a nitrogen expansion system (Vernit or Hornit), the heating installation remains stable and protected against oxygen ingress and pressure fluctuations.

Key benefits of nitrogen solutions

Nitrogen plays a crucial role in stabilizing and protecting the heating system. It prevents oxygen-related problems such as corrosion and cavitation.

Key benefits include:

Protection of buffer tanks by preventing oxygen ingress and corrosion
Longer lifespan of heating installations through degassing and filtration
Reduced contamination and corrosion within technical installations
Lower operational risk: stable pressure and reduced oxygen exposure limit malfunctions and unplanned downtime

Industrial applications in Greenhouse Horticulture

Presscon nitrogen systems are applied to maintain stable pressure in buffer tanks and for biological applications where oxygen reduction is required in enclosed climate chambers, such as pest and micro-organism control.

Buffer tank protection

A stable nitrogen blanket prevents oxygen ingress and maintains constant pressure within the buffer tank. This reduces corrosion risk, prevents pressure fluctuations and ensures a reliable thermal buffer.

Protection of heating systems

Heating systems are vulnerable to oxygen-related wear. Presscon systems degas and filter heating water, reducing corrosion, air pockets and sediment build-up. This results in longer pipe and boiler life and fewer service interruptions.

Compressed air supply for greenhouse automation

Presscon supplies reliable compressed-air systems for greenhouse automation, including valves, screen installations and sorting lines. When combined with the patented PEC Controller, growers achieve significant energy savings and full control over compressed air consumption.

With over 25 years of sector-specific experience, Presscon delivers custom nitrogen and compressed-air solutions to greenhouse growers worldwide.

Key nitrogen solutions for greenhouse horticulture

For greenhouse applications, Presscon supplies dedicated nitrogen systems tailored to the type of buffer tank and the intended use. With the Vernit, Hornit and BPC-Gen systems, growers benefit from reliable and energy-efficient solutions for pressure control and pest control.

Vernit & Hornit – nitrogen expansion systems for buffer tanks

The Presscon Vernit is designed for vertical buffer tanks and creates an efficient nitrogen blanket above the water level. By accurately regulating pressure (typically within a range of approximately 10–18 mbar), a stable water level is maintained and consistent pressure is ensured within the heating system.

The Presscon Hornit is developed for horizontal buffer tanks and regulates total system pressure (both water and nitrogen pressure) via a nitrogen blanket in the expansion space. This makes the system particularly suitable for installations where water column pressure is limited due to low tank height.

Both systems offer:

Constant pressure control within the buffer tank
An efficient nitrogen blanket to prevent oxygen ingress
Measurement of water level and pressure via sensors
Plug-and-play installation
Open structure for easy access and maintenance
Lower investment costs through a functional, cost-efficient design

BPC-Gen | Multifunctional nitrogen generator for ULO pest control

The Presscon BPC-Gen (ULO system) is a multifunctional nitrogen generator that uses HP-PSA technology. The Presscon BPC-Gen (ULO system) is a multifunctional nitrogen generator that uses HP-PSA technology. This system is used for ULO (Ultra Low Oxygen) treatments, such as in biological pest control and other applications where a controlled low-oxygen environment is required.

The BPC-Gen is characterised by:

Modular design, scalable to the required capacity
Up to about 40% lower compressed air consumption compared to traditional generators
High measurement accuracy through proprietary sensor technology
Full insight through monitoring and data logging
Long service life and multifunctional deployment

Sustainability

Sustainability is an integrated part of every nitrogen system we design for greenhouse horticulture. By engineering and producing all installations in our own Dutch factory, we minimize transport, reduce material waste, and maintain full control over long-term quality.

Our HP-PSA technology significantly reduces compressed air consumption, allowing growers to use less energy while still having stable, pure nitrogen. The modular design of our generators ensures that only individual components are replaced during maintenance, resulting in less waste and minimal downtime.

For growers, this means a future-proof solution: stable processes, lower environmental impact and nitrogen systems designed for long-term efficiency.

Frequently Asked Questions

What are the main benefits of nitrogen in greenhouse systems?

Nitrogen prevents oxygen ingress in buffer tanks and helps maintain stable pressure conditions. This reduces corrosion risk, limits pressure-related disturbances and increases overall operational reliability and equipment lifespan.

How pure should nitrogen be for horticultural applications?

Presscon supplies nitrogen up to 99% purity. Most heating installations function excellently with medium purity.

Can Presscon also help with compressors and air treatment?

Yes. We supply complete compressed air systems including PEC Controller, filters, dryer and pressure vessels. This is essential for clean, dry compressed air to the nitrogen generator and other compressed air customers.
