The New BIOSWEEP MODEL 900

PHOCATOX last month launched the newest version of the BIOSWEEP, the 900 Model . This model replaces older versions, such as the most recent, and now retiring, 700 Model (we will continue to service and repair 700 and older units indefinitely). The BIOSWEEP 900 has a number of improvements which have resulted in greater system reliability, greater durability, and drastically increased output. I would like to share some of the details of these improvements with you.

System Reliability- A new solid-state, fully electronic timer switch replaces the older, wind-up mechanical timer switch which, over time, became susceptible to hanging up and sticking in the timer cycle. This occasionally left units running and required manual shutoff as well as extra time for degradation of any residual gases exported from the unit. Also with the new timer, run times are limited to ten hours continuous before the unit must be re-started again, eliminating the on-hold function. Around this, newer and better panel configuration and wiring further ensures protection against control failures. Last but not least, redesigned internal wiring configurations allow for continued (temporary) operation of a BIOSWEEP with one or more failed or even broken lamps.

Greater Durability- In addition to the improved wiring and controls, the new 900 is designed to withstand greater shock than older model units. In older models, our proprietary PHOCATOX UV lamps were bracketed directly to the frame with no shock adsorption. Even moderate bumps and the smallest drop could result in broken lamps, and a ‘down’ unit with a repair and bill on the way. Now all lamps are integrated into an interior proprietary bracket assembly, called a floating core, onto custom-built steel springs. The result is a far more rugged unit which should serve to minimize unintentional and non-warranted damage to the BIOSWEEP.

Increased Output- Ongoing R&D efforts have led to drastic increases in the export levels of H202 and 03 gases produced by the BIOSWEEP 900, which have averaged around 50% higher than the output levels of older model BIOSWEEPs, and we have adjusted our operations manuals accordingly to modify treatment times where applicable. The increased exports of oxidants are attributed to better sources for the custom production of internal electronic components of our proprietary system.

In another upcoming blog post, we will discuss in detail our methodology and formulas used in stating gas output values, including relative ambient temperature and humidity values.

On behalf of the manufacturing and service side of PHOCATOX, we are proud of the way our equipment has become a leading decontamination technology here in the US and abroad, and my partners and I are grateful to have so many qualified and competent service providers.
