Case Study — CS001
Office Block (High Humidity)
Client: Office Building — Queensland | Sector: Commercial
Situation
An office block in Queensland is located in an area that experiences almost 100% humidity at certain times of the year. This condition leads to a significant mould infestation on all indoor surfaces, including the air conditioning ducting.
To address the infestation, the building underwent expensive remediation on a regular basis. The facility managers also fitted a separate dehumidifier inside the air handler. The remediation plan previously adopted had no longevity.
Treatment
A microbial contamination study was carried out over one week. During this time, the humidity range was recorded at 68%, with temperature ranging between 29–33°C.
Test Methodology
- 01As standard practice, a baseline reading was taken prior to introducing SAN-AIR into the system.
- 02Two sizes of SAN-AIR were placed into the Plant Room: 75g and 500g gel packs.
- 03At the end of the week, readings were taken again; microbial tests were taken from different return air points to obtain comparison readings.
Result
- In both cases, there was at least a 75% reduction in mould counts
- Mould reappearance did not occur
- Four months later, staff in the building commented that the musty smells were gone and that they were pleased that the indoor air felt fresh
- The air conditioning coil fins looked visibly clean
Conclusion
SAN-AIR was able to reduce the mould counts by 75%, even in an environment prone to high humidity.
