HSBC’s prestigious data centre is situated adjacent to a landfill area and the odour from it entered the building via the fresh air system causing employee distress and health concerns.
Our custom built engineering system RA-805 was installed ‘in line’ of the building fresh air system to remove the VOCs, bacteria and odour included in the airflow.
This resulted in the removal of the strong odour and any potential health issues.
One of the world’s largest international airports with over 73 million passengers and 5 million tons of cargo handled each year.
We introduced our RH-490C (ceiling unit) and our RH-220 (mobile duct system) in smoking rooms and passenger washrooms. These units decomposed the heavy cigarette fumes and also the odours in washrooms resulted in remarkable Air Quality (AQ) performance improvement. This provided a comfortable and relaxing environment to the airport passengers and also airport working personnel.
Histology routines including instrumentation for grossing, embedding and various staining techniques affected air quality, high volumes of formaldehyde fumes , TVOCs and DAB were continuously given off.
The grossing area the VOC concentration was 0.560mg/m³ in a passive environment (instruments switched off), whereas in the rest of the lab was around 0.120mg/m³.
After operating the air treatment units for a night, the concentration of formalin in the grossing area dropped to 0.260mg/m3 whereas in the other area of the lab it was 0.032mg/m3. The concentration continued to decrease as well over successive days.
Staff welcomed the significant reduction in odour and the effects of harmful gases, particularly formaldehyde.
Daily histology routines and instrumentation continuously giving off formaldehyde (HCHO) fumes (now classified as a carcinogen), and TVOCs from Xylene and DAB used in special staining techniques.
Demo test results showed high average levels of HCHO/TVOCs at 0.762/2.334mg/m³ before NCCO units installed. These levels dropped significantly to 0.114/0.687mg/m³ with a clearance rate of 85%/71%.
RHT ceiling units – RH-490C were introduced and soon the staff found significant improvement in the lab environment quantitatively and qualitatively.
