How does a Medical Chiller Work?

A Medical Chiller is categorized into several types, each of which has its working procedure. These procedures include:

  • Open Loop

An open-loop Medical Chiller continuously circulates the fluid for regulating its temperature. The liquid travels from a central open tank to the Medical Chiller and back to the container.

It frequently cools with water rather than air. A Medical Chiller has a lower scale and energy needs since it has a water-based condenser with a limited surface area.

The open-loop for Medical Chiller is often quieter as it does not have any fans. It is great for keeping MRI machines, CT scanners, and pharmaceutical processing equipment cool.

  • In-Line

Medical Chiller has in-line devices in the evaporator to cool the circulating fluid under heat.

The fluid comes from a central bank, and the fluid is circulated by a pump located near the tank.

Medical Chiller also benefits CT scans and other uses that require the pump to be next to the tank.

  • Drop-In

The Medical Chiller rests on top of a tank to keep the fluid around an evaporator coil cold.

A pump circulates fluid throughout the stainless steel evaporator coil, ensuring adequate cooling inside.

The temperature of the fluid is monitored by a controller, which governs fluid cycling to keep the temperature constant. A drop-in Medical Chiller works well for CT scanners.

  • Closed-Loop

A closed-loop Medical Chiller has a coolant that circulates from a tank located inside them. Until returning to the tank, coolant passes into a sealed coolant loop and coil.

Before returning to the reservoir, the coolant dissipates heat in an evaporator.

The temperature of the coolant is sensed by a temperature controller, which regulates the evaporator to maintain the coolant at the target temperature.

PET scanners, x-ray devices, and progress all benefit from closed-loop chilling.

What are the Types of a Medical Chiller?

Medical Chiller is often distributed into different categories depending upon the Application it is used for. This classification includes:

  • For MRI Machine 

MRI devices produce accurate images of the interior of your body using a powerful magnet, radio waves, and a screen.

For an MRI machine to function properly, the magnet inside must remain cold. The magnet and, as a result, the MRI system will stop working if it overheats.

Using either air or water-cooled Medical Chiller, the heat from the MRI machine is transferred.

A water-cooled Medical Chiller transmits heat to a recycled process fluid, while the air-cooled one transfers heat to the surrounding air.

  • CT Scanner Chillers

CT scans are used by doctors to check for blood clots, cancers, bone breaks, and other conditions.

CT scanners have an x-ray tube that heats up easily and has to cool off for 10 to 30 minutes. This cooling period prolongs hospital care and raises healthcare costs.

Medical Chiller is used in health hospitals to reduce cooling time.

  • PET Scans

PET scanners create three-dimensional photographs of internal organs. Without a Medical Chiller, their work produces too much heat for the scanners to continue working.

A Medical Chiller must remove this heat to prevent the device from malfunctioning.

  • Linear Accelerator Chillers

External beam radiation therapies for cancer patients are most often performed using linear accelerators. High-energy x-rays or electrons are sent to the tumor area by these instruments.

The x-ray tubes, on the other hand, produce a lot of noise. Medical Chiller provides a continuous cooling solution to make these accelerators work properly.

Why do you Need a Medical Chiller for your Application?

  • Cool Down Pieces of Equipment

A Medical Chiller is used to cool off huge pieces of machinery that produce a lot of heat.

Heat is produced by MRI machines, PET and CT scanners, lasers, x-ray machines, and linear accelerators. To run for an extended period, they require rapid cooling.

  • Keep Sensitive Medical Samples.

It is often used to maintain the proper temperature of vital medical tests (such as blood samples) and is commonly used in medical laboratories.

  • Heatless Surgical Procedures

Certain operations should be done without the use of heat in surgical applications to extract heat from a patient’s body.

Hair and tattoo removal, laser eye surgery, and vein treatments are examples of procedures that involve removing heat from body parts or lowering a patient’s body temperature.

What are the Advantages of a Medical Chiller for your Medical Applications?

  • Premium material construction
  • Superior reliability
  • Eco-friendly
  • Efficient heat control
  • Low power consumption
  • Balanced refrigerant flow
  • Customizable
  • Easy to fit

  • Rubber Casters

They offer full durability.

  • Weather Resistant

In most climates, outdoor installation is possible.

What are the Main Controls of a Medical Chiller?

  • Auto Fill

The float switch detects the amount of liquid in the tank and enables the control valve on the line to hold the tank full.

  • Auto Switchover to City or Plant Chilled Water

In the event of a pump or compressor failure, the system will automatically turn to city or plant chilled water.

  • Close Temperature Control

The combination of a solid-state temperature controller and a hot gas bypass keeps the liquid temperature within 5°F of the fixed point.

  • Flow Meter

It is attached to the discharge section.

  • Temperature Interlock (High/Low)

When the water temperature approaches the high-temperature level (indicating potential refrigeration failure) or becomes too low

  • In-line Sensor

In unfortunate conditions, an in-line sensor activates a warning light, an audible alert, or the system shuts down to prevent damage.

What are some Significant Medical Chiller Configurations?

  • Explosion-proof electrical specifications that help in controlling hazardous conditions
  • Remote sensors for distant operation.
  • Dual refrigeration systems to manage varying loads
  • Exclusive paints and weatherproofing properties

Why is Temperature Control Important in a Medical Chiller?

Some medical instruments are equipped with sensors or controls that detect and control the temperature of processes inside spaces due to the delicate nature of clinical procedures.

As most surgical processes require devices that can generate a lot of heat, they should be cooled quickly to maintain a consistent process temperature.

Processes in medical facilities are often required to operate within a small temperature range.

The internal magnet of an MRI system, for example, should be held at -270 °C (-450 °F) (a cryogenic temperature).

Temperatures above this point will cause the system to break down or provide incorrect readings.

A Medical Chiller can provide the needed cooling to maintain the machine’s internal temperature down.

It can handle a wide variety of heat loads and has long-term dependability.
