WEST JEFFERSON MEDICAL CENTER ATTAINED PRECISE TEMPERATURE AND HUMIDITY CONTROL FOR ITS ROBOTIC SURGERY SYSTEM USING TRANE’S NEW CDQ™ DESICCANT DEHUMIDIFICATION SYSTEM.

MAKING MIRACLES POSSIBLE!

Few HVAC applications are more critical than in healthcare. Trane recently helped West Jefferson Medical Center (WJMC) attain precise temperature and humidity control for its new CyberKnife™ robotic surgery system using Trane’s new CDQ™ (Cool, Dry, Quiet) desiccant dehumidification system.

CHALLENGE

WJMC recently installed the revolutionary CyberKnife robotic surgery system. This new robotic surgery combines image guidance technology and computer controlled robotics to enable delivery of high doses of radiation with sub-millimeter precision. Thanks to this accuracy, multiple areas of the body can be treated non-invasively including the brain, spine, lung, prostate, liver and pancreas. The system does require, however, very precise control of operating room temperature and humidity. In Louisiana, where outdoor relative humidity is seldom 50 percent or less, this is a major HVAC challenge. Ronny Gann, WJMC Director of Facilities Management, said, "After installing the CyberKnife system we realized that we did not have adequate humidity control. We needed a solution quickly!"

SOLUTION

Gann asked Tim Goatley at Trane’s New Orleans office for assistance. “We called on Trane because we’ve had a long, successful facilities management relationship with them.” Goatley realized that the project was an ideal application for Trane’s new CDQ™ system. This desiccant dehumidification product is ideal for facilities requiring lower dew point settings and can increase cooling coil capacity by 20 to 300 percent. Chilled water temperatures can be set higher, saving energy and eliminating reheat or exhaust air. Standard air conditioning coils have limited dehumidification capacity. The air dew point can not be lower than the coil temperature —the dew point barrier. The CDQ unit breaks this dew point barrier using an energy recovery desiccant wheel that transfers humidity from the supply air to the return air or mixed air. As a result, the cooling coil can remove up to 200 percent more moisture per hour!

RESULTS

Since installation of the CDQ system, Gann has had no complaints whatsoever from the surgical staff. WJMC surgeons and patients can now take advantage of the CyberKnife system benefits whenever needed without humidity concerns. Ronny Gann said, "Trane performed admirably. They had one weekend to get the CDQ equipment installed and it was to be up and running by 7:00 a.m. on Monday morning. Actually, the installation was completed on Sunday afternoon!"
