Compressed air for the marine market
At Verhaar Omega we understand the vital importance
of having a reliable and robust compressed air system
onboard your vessel. Whether used for starting up the
main engines, supplying air to your control systems or
connected to the working & service air system, your
system should be instantly available around the clock.
With over four decades of marine experience, Verhaar
Omega designs, manufactures and supplies premium
compressed air systems to the highest Dutch standards.
From small factory-standard units to custom-made
skid-built units designed to meet the specific requirements of your application.
Units specially developed for inland water shipping
applications
Our compact screw & piston type air compressor units
are combined with matching air dryers and air receivers. They are the ideal solution for supplying air onboard
inland tankers and dry cargo ships. Typical fields of application are general service air, sounding, stripping pumps
and air supply for air mask filters.
Our skid-built starting air compressors are pre-wired and
connected, ready for start-up upon delivery. With robust
and proven technology, combined with a compact design,
they provide the ideal solution for all your onboard starting air applications.
Units specially developed for seagoing vessel
applications
When efficiency combined with reliability matters, our
standard delivery programme and special designs are
able to fulfil all your compressed air system needs.

Verhaar Omega HZ-series high purity nitrogen generators
Verhaar Omega Air & Nitrogen BV is your ideal partner
for the design, manufacturing and supply of a high
purity nitrogen generator system. With dedicated design
for versatile applications on board all types of gas
carriers and tankers, offshore applications and other
nitrogen requiring services in the oil & gas industry, the
Verhaar Omega HZ-series high purity nitrogen generators will suit your needs.
By applying the pressure swing adsorption (PSA)
method for separating the oxygen and nitrogen from
the compressed air, high purity nitrogen is now available for your specific application.
The range Verhaar Omega HZ-series high purity nitrogen
generators varies from units producing 5 nm3/hr to the
larger units with a capacity upto 1300 nm3/hr.
All the systems are standard calibrated and designed
for a guaranteed nitrogen purity of 99,5%. The Verhaar
Omega HZ-series high purity nitrogen generators however can produce nitrogen gas up to a purity of 99,9%
in their standard design.
Using our in-house design and manufacturing expertise,
we can customise specific capacities, purities or special
applications upon your request.
Product philosophy
Verhaar Omega HZ-series high purity nitrogen generators are designed by using innovative solutions for
demanding applications.
• Complete system design and supply
• High nitrogen capacity with minimum unit
dimensions
• Constant and reliable production of nitrogen on
demand of your selected purity
• Easy and minimal maintenance
• Self maintaining and intelligent system control
• Clear and simple system operation
Unit design
The generator units are constructed in such a way that
they can withstand the harsh environment often found
onboard ships, offshore units and at oil & gas applications. Special measures are taken to protect against the
potential damages caused by vibrations and aggressive
ambient air conditions.
Equipment is fitted with complete stainless steel piping
and instrumentation, while the frame, CSM columns
and buffer tank constructions are preserved by a high
quality marine paint system or alternatively are of
galvanised materials. Valves used in the system downstream the generator are fitted with chemical resistant
seats and seals.
Feed air treatment equipment
The efficient life span and performance rate of the
Verhaar Omega HZ-series high purity nitrogen generators depends heavily on the quality and correct quantity
and pressure of the compressed feed air entering the
CSM columns.
Our systems feature a modular air treatment package.
Before feed air enters the CMS filled columns it passes
through a multi-stage air treatment package. The air
pre-treatment system ensures a long life-span for your
installation, combined with a minimum of maintenance
costs and efforts.
One Touch control system
The One Touch control system consists of a PLCcontrolled system, fitted locally on the generator unit.
A colour touchscreen makes monitoring and operating
the nitrogen generator clear and simple. Depending on
the application, remote placed control and status panels
are available for deployment in the cargo control room,
bridge or engine control room.
When required Verhaar Omega HZ-series high purity
nitrogen generators include the complete valve arrange-
ment to be fitted in your nitrogen deck lines (double
block & bleed), pressure transmitters and other required
instruments.
By supplying the complete system and accessories, we
secure the reliability of your system. Also available are
class-approved buffer tanks for nitrogen storage, high
flow and high precision pressure reducing valves, and
instrumentation for your strip, pad and blanket lines.
All these instruments and equipment are fully incorporated in the One Touch control system.
Service & Commissioning
Verhaar Omega HZ-series high purity nitrogen generators are designed and manufactured to the highest standards, ensuring you excellent performance
combined with maximum durability. Technical assistance is available from our team of engineers during the
onboard installation of equipment, commissioning and
for after-sales maintenance.
Certificates & certification
Verhaar Omega HZ-series high purity nitrogen generators meet and are available with a certificate issued by
the major classification bureaus such as LRS, GL, BV,
DNV, ABS, RINA and RMRoS.
