Our commitment to excellence and a deep understanding of diverse environmental needs have established us as a trusted leader in the HVAC industry, serving both urban and remote locations with unparalleled expertise.
Completed Projects
HVAC system types successfully supplied, installed, and commissioned
- Direct Expansion (D/X) based split and packaged type units (rooftop packaged, mid-wall, under-ceiling, cassette, and floor mounted console type systems).
- Water and Air-Cooled liquid chillers of the screw, scroll, centrifugal and reciprocating type, operating on various refrigerants (R22, R134a, R407c & R410a).
- Energy Saving, thermal storage systems – Calmac Ice Tanks linked to chilled water generators or refrigeration plants with heat exchangers (Mono-Ethylene or Propylene Glycol), thereby allowing for the production of ice during off peak or reduced electrical costs.
- 100% Fresh-Air, chilled water air-handling units, with two- and three-way control valves.
- Chilled and condenser water pipe systems, including pumps/motors, steel piping, valves, strainers, insulation / cladding and galvanised steel condenser water piping.
- In-ceiling ducted type exposed mid-wall / cassette type with two- and three-way control valves, balancing valves, strainers, isolation valves and electrical heater banks, complete with all associated controls, safety interlocks and various types of control thermostats.
- Variable refrigerant flow systems (VRV – old and new generation).
- Kitchen extraction and make-up fresh air systems (both with and without cooling – chilled water and D/X).
- Kitchen canopies with associated extraction systems for baking, frying and high-volume cooking (utilizing St/St 304 and 316 and fitted with Ultraviolet or Standard extraction systems).
- Canopy fire suppression systems – Ansul type.
- Fire dampers – motorized and spring-loaded type.
- Smoke extraction systems – in the event of a fire (retail outlets).
- All types and sizes of ducting, galvanised steel / Black Steel and Stainless Steel (round or rectangular type), with or without internal / external insulation (we no longer promote the use of internal Sonic Lining). We offer Comprifix on internally insulated ducting and Foil Faced Insulation on externally insulated ducting.
- HVAC electrical panels – main and sub, complete with design, manufacture, supply, and installation.
- Building Control Systems (BMS).
- Diffusers, grilles, weather louvres and jet nozzles.
- Fresh air supply fan systems to ensure correct IAQ (Indoor Air Quality).
- Extraction systems to waste areas, ablution blocks, laundries, and basement parking areas – that do not have adequate ventilation.
- Various fan systems and controls to suit – Axial and Plate Axial (cased), forward curved, backward curved, and In-Line tube fans. All fan systems with silencers / sound attenuators (podded or purpose-built with galvanized or stainless steel).
- Cooling towers, condenser water pump stations associated controls and water treatment systems.
- Close temperature control systems for server rooms and product-sensitive environments (typically medical).
- Humidity-controlled environments. SAS has successfully designed, supplied, installed, and commissioned several biltong drying systems complete with purpose-built coils and controls to suit.
- Chilled water expansion tanks with all associated valves, piping and air-bleed-off with ball valve fill station.
- Spot Cooling Applications, utilizing our own imported range of mini-duct high-velocity air-handlers.
- Drop Temperature Systems, complete with controls for various types of food prep areas (i.e. meat prep, fish prep, vegetable prep and bakery prep – all with varying temperature requirements to best suit the class of food being prepared).
