Choose the Right Solution for Your Application
Not sure which solution suits your HVAC design? Our product experts recommend matching fan size (80mm, 120mm, etc.) and airflow (CFM) to your heat load calculation, and verifying controller input types (thermistor, RTD, digital). Below is a comparison of thermal management options relevant for South African HVAC builds and retrofits:
| Product Type | Typical Spec Range | Key Brands (at Communica) |
|---|---|---|
| Axial Fans | 80-140 mm, 12 V-230 V, 30-240 CFM | Sunon, Delta, NMB-Minebea |
| Temp Sensors | -40 degreesC to 125 degreesC, digital/analog | Honeywell, Amphenol, Adafruit |
| Temp Controllers | Panel/DIN, relay/SSR output | Omron, ABB, Select |
| Heaters | 10 W-1000 W, cartridge/pad/PTC | Generic, Adafruit |
Lead Time Note: High-demand components such as fans and industrial controllers are regularly restocked for the South African market. For large or unusual orders, Communica provides estimated lead times on request, and offers pickup or courier fulfilment per your preference.

Specification and Compatibility Guidance
Start by confirming the voltage and current requirements for your target zone or air-handler unit. For fan selection, use the formula:
Example: For a 50 m3 lab requiring 6 air changes per hour: (50 x 35.3) x 6 / 60 ~ 176.5 CFM. Match this value to the fan specifications for optimal performance.
Temperature controllers need to be compatible with your sensor choice (thermistor, RTD, or digital I2C/SPI). Review each controller's datasheet for approved input types and relay ratings.
