LMB CT Tube Technology

CT REPLACEMENT TUBES WITH LMB

LONG LIFE AND SMOOTH OPERATION

Dunlee, your trusted partner for CT replacement tube offers the DA200P40+LMB, the first replacement tube with Dunlee`s CoolGlide™ liquid metal bearing (LMB) technology.

DUNLEE tube profile

Tubes with CoolGlide™ are prized for their long life, made possible because the liquid metal bearing does not create friction, so there is virtually no wear. The DA200P40+LMB tube also features a quieter sound pattern¹ for a more smooth operation   and a pleasant patient experience compared to CT tubes with Ball Bearing.

DESIGNED FOR GE REVOLUTION™ EVO AND OPTIMA™ CT 660 CT SCANNERS

DUNLEE DA200P40+LMB tube

The DA200P40+LMB tube has been specifically designed as a replacement tube for the GE Revolution™ Evo and Optima™ CT660 CT scanner.

THROUGHPUT

Those user who value throughput will appreciate how the outstanding heat dissipation of liquid metal bearings means there's no need to wait for the tube to cool down between exams, even in demanding applications that require many scans or ultra-high image quality.

EFFICIENCY

Users can turn on the system in the morning, and it will run all day without interruption and less wear. The ability to quickly gear up to operation mode makes LMB tubes particularly well-suited for emergency situations.

RELIABILITY

Your customers who expect reliability will value the fact that LMB tube has less wear because there is no contact within the bearings, enabling longer tube life. For traditional ball bearing tubes, ball bearing failure is a primary cause of tube failure.

CoolGlide™ LMB – High Troughput

CoolGlide™ LMB – High Reliability / virtually no wear

 

The bearing shaft and sleeve glide on a liquid film. The liquid is pumped  to the interior of the bearing by spiral grooves. As there is no direct contact during operation, there‘s virtually no wear.

CoolGlide™ LMB – High Troughput

Traditional Ball Bearing – Wear off, risk of binding and jamming

 

With operation, the lubricant (which is usually silver or lead metal) wears off of the ball and race surfaces, resulting in steel-to-steel contact that leads to binding or jamming. High temperature and high speed will reduce bearing life the most.

PATIENT EXPERIENCE

Customers looking for ways to provide a better patient experience may be impressed with the quiet operation of LMB tubes. With traditional tubes, the metal interlayers and ball bearings make noise when they come in contact. But with LMB tubes, there is no audible bearing noise.

CoolGlide™ LMB – High Troughput

CoolGlide™ LMB – Low Noise / No contact of bearing and shaft

 

As there is no direct contact , there is no audible bearing noise during operation.

CoolGlide™ LMB – High Troughput

Traditional Ball Bearing – Noise and Vibration

 

The movement of the ball bearings result in noise and vibrations whenever the CT scanner is used.

"We purchased the first DA200P40+LMB tube in December 2020 and the second one shortly after. Both have been running without interruption since then – smooth and quiet. We calculate the cost of ownership for our customers, and product lifetime is a key part of the calculation. With Dunlee CT tubes, we have an advantage."

SUCCESSFUL INSTALLATIONS IN USA AND EUROPE

 

The DA200P40+LMB tube has been successfully installed at sites in the United States and Europe. Alexander Eitel, Dunlee Head of Marketing and Business states, "Having a CT replacement tube alternative to OEM tubes helps our customers --and the patients and hospitals they serve --in offering affordable   healthcare and allows them to choose their partner of trust. The feedback we've received is that service engineers like the easy installation, while radiologists like the smooth operation, and patients appreciate the quiet environment. The ability to run without interruptions was especially important when Covid demanded high patient throughput."

A HISTORY OF LMB EXPERTISE

 

The research and development team that was the first in the world to bring LMB technology to the X-ray market in 1989 developed the DA200P40+LMB tube. With over 100,000 LMB units sold worldwide, the team built on its expertise when developing DA200P40+LMB with CoolGlide™.

MANUFACTURED IN THE USA

 

All DA200P40+LMB tubes are manufactured in Illinois, USA with imported parts. The Liquid Metal Bearing   with CoolGlide™ is designed and manufactured in Germany, based on knowledge gained from over 30 years of LMB technology development and over 100,000 LMB units sold worldwide.
