Dehumidifiers for CT Scanners & X-Ray Rooms: A Solution to Protect High-Value Medical Assets

In the field of high-tech medicine, investing in diagnostic imaging systems like CT Scanners and X-Ray machines is a critical financial decision. These systems, valued at millions of dollars, require an operating environment with precisely controlled parameters. However, an often-overlooked factor that can silently destroy these investments is humidity. This article will provide an in-depth analysis of the impact of humidity and present a specialized control solution for the medical industry from the heat and humidity experts at DeAir.

Humidity Standards from Original Equipment Manufacturers (OEMs)

To ensure equipment performance and longevity, the world's leading manufacturers have very specific requirements for the machine room environment. Adhering to these standards is not just a recommendation but also a prerequisite for the manufacturer's warranty coverage.

• GE HealthCare: In the installation guide for the Revolution CT series, GE specifies that the relative humidity of the machine room and control room must be maintained between 30% and 60% (non-condensing). (Source: GE Healthcare Site Planning)
• Siemens Healthineers: For the SOMATOM Confidence system, Siemens requires the room's relative humidity to be within the 20% to 75% range. Other documents even suggest a tighter optimal range of 50-60%. (Source: Block Imaging Analysis)

These figures clearly show that a standard air conditioning system, which only has secondary dehumidification capabilities, cannot reliably maintain this safe operating humidity range, especially in Vietnam's hot and humid climate.

In-Depth Analysis: Risks of Operating Outside Standard Humidity Ranges

For engineers, doctors, and administrators, understanding the technical risks posed by humidity is the first step toward protecting assets and ensuring operational efficiency.

1. Risks to Engineering & Hardware

• Micro-corrosion and short circuits: Humidity above 60% RH is the ideal condition for initiating electrochemical corrosion on printed circuit boards (PCBs), component leads, and connectors. This phenomenon is initially very difficult to detect but will lead to intermittent signal errors and, more seriously, short circuits, completely destroying expensive electronic modules.
• Discharge in high-voltage blocks: X-Ray and CT systems operate at extremely high voltages. Humidity in the air reduces insulation resistance, increasing the risk of electrical leakage and arcing between terminals, which can damage the X-ray tube and high-voltage power supplies.
• Inaccuracy of detectors: The detector is the heart of the system, determining image quality. Water vapor condensing on the detector surface can alter its physical properties, causing signal degradation and leading to serious errors in image reconstruction.

2. Risks to Operation & Diagnostic Quality

• Noise and artifacts: Signal errors caused by humidity often manifest as noise or abnormal streaks and rings on the image (artifacts). This can obscure small lesions or, worse, lead to misdiagnosis, directly affecting patient safety.
• Increased downtime: Once the equipment reports a humidity-related error, the hospital faces downtime for repairs. This not only disrupts the examination and treatment workflow and reduces patient throughput but also affects the medical facility's reputation.

Why Is Air Conditioning Not Enough?

Many believe that a standard HVAC system is sufficient for environmental control. This is a misconception. Air conditioners are primarily designed to control temperature (sensible heat load) and only have secondary, non-specialized dehumidification capabilities. In Vietnam's climate, where outdoor humidity is often above 80%, it is difficult for an air conditioner to maintain a stable humidity level within the 40-60% RH range recommended by medical equipment manufacturers. This is where a dedicated DeAir industrial dehumidifier becomes mandatory.

The Olmas Solution: Reliable Performance, Durable Operation

With experience in consulting and implementing solutions for many medical facilities, DeAir recommends the Olmas industrial dehumidifier line. This brand is proven for its durability and effectiveness, distributed officially by DeAir with professional technical services. The OS-150 and OS-500 models are particularly suitable for this application.
