HEX Overhead

Introducing a new affordable
Twenty Four Bulb
UVB-Narrowband
Full Booth for clinics.

At less than half the cost of any other clinical-grade phototherapy booth on the market, the SolRx HEX combines power with affordability.

The SolRx HEX is an assembly of six E-Series 4-bulb devices to form a hexagon, with two adjacent patient entry doors. A plastic baseplate holds the devices in position at the bottom, and locking struts firm up the assembly at the top.

The SolRx HEX comes with clear acrylic windows for complete lamp protection, utilizes a passcode locking timer to prevent unauthorized use and can be assembled and ready to use in under an hour.

With a price of less than half of clinical phototherapy booths on the market today, the SolRx HEX is the clear choice for clinics big or small.

Relamping costs are cut in half with only 24 lamps being used while treatment times still remain short and effective for quick and easy patient throughput.

 

Overview

The SolRx HEX is a modular system, consisting of one E740 Master device that controls five additional units. All of these are assembled onto a 1/2″ thick plastic baseplate. Here’s what this means for you:

Each unit is lightweight and easy to handle, weighing less than 50 lbs. They come with sturdy handles on both sides, making them easy to move around. Unlike other bulky clinical devices, our system can be moved simply by sliding the baseplate on the floor – no need for casters.

The system is delivered in six boxes, with the bulbs already installed, plus the baseplate. We’ve made the setup process straightforward to save you costs. Just like our home users, clinics can typically assemble the system themselves within 1 hour, without the need for a technician. This is a significant advantage over other clinical devices that often require additional fees for delivery and setup.

In the rare case of a device malfunction, we can quickly ship a replacement (usually from our stock). The faulty device can be returned in the original packaging, saving you the expense of a technician visit. This is another area where we stand out from other clinical devices that often require costly technician visits.

If you ever need to relocate, the booth can be easily disassembled into six portable units. For added convenience during transport, you can also pair the units, fasten them facing each other, and ensure the bulbs are fully protected.

The SolRx HEX is designed with cost-effectiveness in mind. The total life cost of our system is typically much lower than that of other clinical booths. We’ve made every effort to make our devices as user-friendly and cost-effective as possible.

HEX TIMER

Control System

The SolRx HEX “C01” password-enabled control system allows the clinician to set and lock the treatment time and then leave the area to go on to other tasks. When ready, the patient starts the treatment from within the booth by pressing the start/stop button on the controller. Once the treatment is finished, the bulbs turn off automatically, the timer beeps, and the control system re-locks to prevent the patient from taking another treatment (with the previous treatment time shown in case it was not recorded).

The Master device is typically used as the left “door”, so the controller is accessible to the clinician when the door is open. It is complete with a patient accessible emergency stop pushbutton should they need to stop the treatment. Using it locks the controller. The Master device is also equipped with a keyed switchlock so the booth can be electrically disconnected and fully locked out, which is recommended practice at the end of each day.

The SolRx HEX does not have a “dosimeter”. Treatments are given in minutes:seconds. For a discussion of this topic see “Timed treatments versus dosimetry” below.

Electrical

The SolRx HEX can operate on 208V (typical for commercial buildings) or 230-240V (as in a private residence), at 50hz or 60hz. It requires a dedicated 208-230V single-phase 15-Amp 2-pole circuit breaker and a NEMA 6-15P receptacle as shown below, by others.

Total current draw is nominally 10 amps. An IEC-C19 to NEMA 6-15P SJT14-3 (14 gauge, 3C) power supply cord is included. All devices must be grounded.

Handling

The SolRx HEX is modular, with one Master device controlling five (5) Add-on devices, all assembled onto a 1/2″ thick plastic baseplate. This means that:

  • Each device is easy to handle, weighing less than 50 lbs and complete with a heavy duty handle on each side. The entire assembly can be moved by sliding the baseplate on the floor – casters are not necessary. This is in stark comparison to other clinical devices, which are huge unwieldy things.
  • The system ships in six (6) boxes (with the bulbs installed) plus the baseplate, all by courier or truck. To save costs, setup is easy so just like our many home users, the clinic can do it themselves in typically within 1 hour, instead of a Solarc technician. Again, in stark comparison to other clinical devices, which command additional fees for delivery and setup.
  • In the unlikely event a device ever fails, another can be shipped (typically from stock) and the failed device returned in the same packaging, again saving costs by not needing a Solarc technician. This again in stark comparison to other clinical devices, which command an expensive visit by a factory technician.
  • If you ever need to move, simply disassemble the booth into six easy-to-carry devices. Alternatively, you can disassemble into pairs of devices and for transport fasten them so they face each other with the bulbs totally protected.

The all-important total life cost of the SolRx HEX is therefore typically much lower than that of other clinical booths.

Clear Acrylic Windows for Safety

Instead of traditional wire guards, each device in the SolRx HEX is complete with a Clear Acrylic Window (CAW) to prevent bulb damage and potential patient harm, including from touching the hot ends of the bulbs. 

CAWs allow the patient to move freely within the booth without concern, and CAWs significantly reduce dirt buildup on the bulbs and around the bottom lampholders. CAWs free the clinician from worries about device damage and patient harm, especially if some patients have poor balance.

The CAW material itself has about a 10% loss of transmitted UVB-Narrowband irradiance, but Solarc tests show that is compensated by the cooling provided by the fan in each device, which draws air in from the bottom and out the top, where it can be removed from the room if necessary using a room ceiling fan (by others).

The SolRx HEX can also be supplied with simple wire guards in lieu of the CAWs however, Solarc strongly recommends CAWs for clinics.

Other Features

The six devices of the SolRx HEX are assembled onto a baseplate that sits directly on the floor, to eliminate the need for a patient platform to treat the lower legs. Other booths are on casters that elevate the entire booth several inches, and therefore require a patient platform. The SolRx HEX baseplate is made of 1/2″ HDPE plastic, has a textured surface for safety and is anti-microbial.

Inside the booth, two sturdy handles on opposite sides are available for the patient to steady themselves.

For partial body treatment, any number of devices can be disconnected at the daisy-chained connection cables at the top of the devices, which can save valuable bulb life.

The Solarc SolRx HEX is complete with 24 genuine Philips TL100W/01-FS72 UVB-Narrowband 6-foot bulbs. Solarc is, and always has been, the only company in Canada to which Philips Canada (now Signify Canada) sells their UVB-Narrowband lamps directly.

Why 24 Bulbs?

By limiting this booth to 24 bulbs, the cost is reduced to much less than half of a typical 48-bulb booth, by allowing the use of Solarc’s high-volume E-Series home-use devices. In fact, only the SolRx HEX Master device is special – the five Add-On devices are all 230V home units. A single such booth is thus an economical way to bring UVB-Narrowband phototherapy to your healthcare facility.

When it comes time to grow your clinic, adding a second SolRx HEX has several advantages. For example, two such booths have considerably better patient throughput than a single 48-bulb booth, because the bulbs-on treatment time is only one component of the total time per patient, with the majority of the time consumed by the patient undressing and re-dressing while the booth sits idle. Having two such booths also provides comforting redundancy and flexibility for the clinic.

Also, versus a 48-bulb booth, a pair of 24-bulb booths has better net bulb life because the number of starts/stops is the main contributor to bulb degradation, and some treatments are very fast. UVB-Narrowband bulbs are very expensive, so efforts to maximize their life are important, and of course, rebulbing a 24-bulb booth costs only half that of a 48-bulb booth.

Also, with only 24 bulbs there is less concern for removal of waste heat from the treatment room – a room ceiling fan may not be necessary.

Having only 24 bulbs per booth also provides a wider margin for error with respect to treatment times and resulting dose.

What’s Included With Your Booth

All SolRx HEX units come completes with 24 Genuine Philips TL100W/01-FS72 UVB-Narrowband Lamps installed and ready to use. The unit also comes with a detailed User’s Manual including treatment time guidelines to use as a reference when establishing patient treatment times. 

The SolRx HEX also includes a warranty of 2 years on the device and 6 months on the bulbs. Our Arrival Guarantee also ensures that your unit will arrive in perfect working condition. 

The device also comes with 12 UV Protective Patient Goggles and 1 pair of UV Protective Staff Glasses. Most clinics consider purchasing more UV Goggles and distributing them to patients for use during their sessions.

Timed Treatments Versus Dosimetry

A “dosimeter” measures UVB irradiance in real-time using a light sensor and mathematically integrates it using a built-in computer, until the set dose is achieved and the device is automatically turned off.

The SolRx HEX does not have a dosimeter. Instead, treatments are given in minutes:seconds using a simple and reliable digital countdown timer/controller, with modern “universal voltage” ballasts, so that UVB-Narrowband irradiance is not affected by supply voltage fluctuations. This eliminates complicated sensors, electronics and expensive annual calibrations, which can run into the thousands of dollars (US$3000 reported to us in one case in Florida).

Patient treatment times are determined by:

  • measuring the booth’s nominal UVB-Narrowband IRRADIANCE (mW/cm^2) weekly or every second week using a UVB-Narrowband light meter (also called a “radiometer”). These measurements are typically taken when the device irradiance reaches steady-state; after warming up the booth for at least 5 minutes.
  • selecting the patient’s DOSE (mJ/cm^2) based on the patient’s diagnosis (such as psoriasis, vitiligo or eczema), Fitzpatrick Skin type (I – VI) if psoriasis, duration since their last treatment, and outcome of that treatment. For that, commonly available phototherapy treatment guidelines can be used (such as in the textbook Phototherapy Treatment Protocols for psoriasis and other phototherapy responsive dermatoses. By Zanolli and Feldman ISBN 1-84214-252-6), or Solarc’s own Exposure Guideline Tables from the device’s User’s Manual.
  • calculating the patient’s treatment time using the equation: Time (seconds) = Dose (mJ/cm^2) ÷ Irradiance (mW/cm^2). For that look-up charts are available. Documentation is typically by simple paper records.

The most critical consideration is that treatment times must be significantly reduced when the bulbs are renewed, by at least the ratio of the old to new irradiance values. Failure to do so will almost certainly result in burning patients! It is always best to be conservative in this regard. When in doubt, use the lower treatment time.

Best practice for the management of light meters is to purchase two (2) UVB-Narrowband light meters at the same time, and to keep one locked up and used only periodically to check the validity of the working light meter, perhaps every few months. Using such a method significantly delays the need to return the light meter to the manufacturer for recalibration, and when doing so the other light meter remains available, and as a reference for the returning light meter. UVB-Narrowband light meters are however rather expensive, at US$1500 to US$2500 each.

Also, beware that light meters from different manufacturers are known to give different results, sometimes quite different. This is unfortunate but the important consideration is that one light meter and its calibration is settled on as being the “truth” and not deviated from, because for consistency in a clinic, the relative is more important than the absolute.

UVB-Narrowband light meter sources include: Solarmeter (low cost), Gigahertz Optics, and International Light. Solarc does not sell light meters for a variety of regulatory and quality system reasons.

Note: Once comfortable with treatment outcomes, some physicians may choose to dispense with the above calculations and increment the treatment time by predetermined percentages.

The booth’s measured nominal irradiance data is used to determine when to rebulb the booth, which is ideally done with all the bulbs replaced at the same time, and the treatment times significantly reduced. Alternatively, close-in individual bulb irradiance measurements could be made and bulbs replaced piecemeal, but that can result in irradiance “hot spots”.

Anyone taking irradiance readings must protect their skin and eyes from UVB exposure. A face-shield verified using the light meter to be UVB-blocking can be useful for that.
