A Straightforward CTI 9600 Replacement

The OMNI® 900WL takes over from a water-cooled CTI 9600 by moving the power, cooling water, and helium connections to the new compressor.

Up to Three Pumps on One Compressor

A single OMNI® 900 can support up to three pumps at once, including classic cryopumps and On-Board pumps at the same time.

More Pump and Service Options

A 2-phase/3-phase output switch lets the OMNI® drive higher-performing pumps that the 9600 can’t power, so you aren’t tied to one repair center or source of parts.

Overview

A Water-Cooled Helium Compressor Replacement for the CTI 9600

The OMNI® 900WL replaces legacy water-cooled compressors, drives the cryopumps you already have, and opens the door to higher-performing pumps from other manufacturers.

The OMNI® 900WL is an Edwards – CTI SC water-cooled alternative and allows you to replace legacy cryopumps with superior-performing Marathon® cryogenic pumps.

Benefits of Water-Cooled Compressors

Water-cooled compressors use water as a cooling medium to maintain optimal operating conditions.

Superior Cooling Efficiency

Water-cooled compressors are highly effective in maintaining lower operating temperatures, which supports performance in high-demand applications.

Quiet Operation

Effective heat dissipation through water reduces the need for large cooling fans, contributing to a quieter working environment.

Reduced Energy Consumption

Running cooler and more efficiently can lead to lower overall energy costs and reduced air conditioning demand in the facility.

Longevity and Reliability

Effective cooling helps prevent overheating and reduces wear, extending equipment life and minimizing maintenance and repairs.

Consistent Performance

A steady supply of water maintains heat dissipation under heavy load, supporting applications where continuous operation is critical.

Environmental Considerations

Managing and reusing water through closed-loop systems or cooling towers can minimize environmental impact.

Common Questions

OMNI® 900WL Helium Compressor FAQs

Answers to the questions engineers, maintenance teams, and buyers ask when a legacy compressor needs replacing.

Shut off the cooling water and power to the 9600, move the pump connection to one of the OMNI® outputs, then connect power, cooling water, and the helium lines. Start the compressor and restart the pump. The video on this page shows the steps on a live test setup, so your team can see what the changeover looks like before planning it.

Yes. OMNI® Helium Compressors are designed to operate On-Board® and Cryo-Torr® cryopumps, including standard and auto-regen pumps. The OMNI® 900 has dedicated connections for both classic cryopumps and On-Board® pumps, so you can keep your installed pumps in service and replace only the compressor.

Yes. A 9600 can’t produce the voltage and phasing needed to drive higher-performing pumps from other manufacturers, but the OMNI® can. Its 2-phase/3-phase output switch lets it power Marathon® and GENCRYO® pumps alongside your existing CTI pumps, so you can select pumps by performance rather than by manufacturer.

It depends on pump size. An OMNI® 900 supports up to three On-Board® or Cryo-Torr® 8 or 8F pumps, up to two Marathon® CP8 pumps, or one larger pump such as a Cryo-Torr® 500 or Marathon® CP-20. The compatibility table on this page lists each model. For a mix of pump types, SynSysCo can confirm the load for your tool.

OMNI® Cryogenic Systems interface with both networked and non-networked tools. The host I/O connects to your system for remote start and stop of the compressor and cryopumps. If your tool uses a CTI Network Controller, the patented OMNI PTE module manages the interface between another manufacturer’s pump, the controller, and the host computer. Contact SynSysCo to define the configuration for your tool.

No. Because the OMNI® can drive a mix of manufacturers’ pumps on the same tool at the same time, you can upgrade one pump at a time as your operational needs require. There is no need to replace a complete multi-pump set all at once.

Your pumps can come from more than one manufacturer, which gives you alternative supply for new equipment, replacements, and repairs. OMNI® compressors are serviced in the USA and supported globally through multiple service centers, and SynSysCo also rebuilds most manufacturers’ legacy compressors and cryopumps. You aren’t tied to one repair center or one source of parts.

The OMNI® 900WL is a 3-phase, 30-amp, nominal 208 VAC unit, and high-voltage configurations are available. It draws 6.6-6.9 kW at 50 Hz and 7.5-7.8 kW at 60 Hz and operates in ambient temperatures of 4 to 40 ºC (40 to 104 ºF). It also needs a cooling water supply, so confirm flow and temperature requirements with SynSysCo for your site.

It may be. The OMNI-800 Series operates up to two 8-inch pumps or one 10-inch pump and is also an option for replacing 3-phase 9600 compressors. The OMNI® 900 is the better fit when you need capacity for three 8-inch pumps or larger pumps up to 20 inches. SynSysCo can review your pumps and recommend the right size.

OMNI® Helium Compressors come with a standard 2-year warranty and a scheduled adsorber change every 30,000 hours, which is about 42 months running 24/7. Each unit uses two oil separators plus an adsorber, and its supply and return pressure displays make the compressor easy to monitor.
