Climate-Ready Air Handling Units for High Heat Loads

South Africa’s interior is warming at roughly twice the global average, according to the CSIR.

HVAC Calibration for Indoor Air Quality Monitoring

Sensor drift increases energy use and disrupts comfort. A CO₂ sensor that reads high causes the system to bring in excess outdoor air. This forces coils and chillers to condition more air than needed.

Quiet Efficiency in HVAC Design

Noise isn’t just heard — it’s felt. It steals concentration, shortens patience, and turns comfortable rooms into tiring spaces.

How Custom AHUs Support Sustainable Building Compliance

Sustainable design has moved past being a “nice to have.” For developers, facilities managers, and sustainability officers, it’s now a compliance obligation. Mechanical systems are right in the middle of this. HVAC is often the single biggest consumere of energy in a commercial building,

Custom AHUs and Long-Term ROI

Lowest price wins the tender far too often. But in HVAC, the sticker price is only the start.

Why HVAC in Medical Cannabis Is Mission-Critical

Medical cannabis production isn’t typical agriculture—and it isn’t typical pharmaceutical processing either. It sits at the intersection of both, combining biological sensitivity with strict regulatory oversight. 

Future-Proofing Indoor Environments with Custom AHUs

Sustainable design has moved past being a “nice to have.” For developers, facilities managers, and sustainability officers, it’s now a compliance obligation.

The Role of Custom AHU Design in Achieving Net-Zero Carbon Goals

Unlike off-the-shelf systems, which are built for general applications, custom AHU design allows engineers and HVAC consultants to specify every component—from fan configuration to control logic—based on project-specific criteria. This approach is particularly valuable in buildings targeting net-zero emissions.

Designing HVAC Systems for Long-Term Hygiene

Air handling systems are central to maintaining safe, healthy indoor environments—but not all HVAC designs are created with hygiene in mind.

How Poor HVAC Maintenance Causes Microbial Contamination

The unseen risks of poor HVAC maintenance extend far beyond temperature discomfort or system inefficiencies.
