High-airflow cooling at a fraction of conventional AC energy. We design, manufacture
and support direct, indirect and hybrid evaporative systems for South African conditions.
Large floors and high-volume spaces are costly to condition with traditional air-conditioning. In summer heat, compressors struggle while electricity costs soar.
Declining team productivity and focus as summer temperatures climb
Poor client and visitor impressions in uncomfortable meeting spaces
Peak-season electricity spikes
Equipment overheating and downtime
Evaporative systems provide fresh-air cooling with markedly lower energy use when correctly engineered for the space and climate.
Locally designed and produced Cirrus units for rapid lead times and stocked spares
Engineered for SA dust, heat and serviceability with robust components
Supported by Crown's installation, commissioning and SLA programmes
You receive an itemised scope and agreed timelines. We commission and document your evaporative system—airflow readings, supply-air temperature, pump operation, pad condition and bleed-off set-points—with hygiene and safety sign-offs in your handover pack. Priority response is included under your SLA, and seasonal servicing (pads, pumps, sump cleaning and water-quality checks) is scheduled to keep performance consistent.
We design, install and service grid-tied & hybrid solar power systems, direct/indirect evaporative air-conditioning, and water storage, purification & filtration solutions for homes and businesses, backed by a dedicated maintenance division.
Every system is engineered for South-African conditions: high-efficiency bi-facial panels, Li-ion batteries and optional generator integration ensure uninterrupted power during load-shedding, with performance guarantees of 25 years on panels, 5 years on inverters and 10 years / 6 000 cycles on batteries.

Direct and indirect evaporative systems deliver world-class CoP values—e.g., a 1 kW residential system cooling an entire home—using up to 6–10 × less power than conventional DX air-con units.
In very humid climates indirect or hybrid evaporative systems are recommended; they pre-cool incoming air without adding significant moisture, maintaining comfort while still cutting energy use.
We implement rain-harvesting or borehole storage, UV sterilisation and multi-stage filtration. Benefits include reduced municipal dependence, healthier water quality and higher property value.
A 1 000 L residential storage-plus-UV system can be installed in as little as two business days; larger commercial projects are scoped individually.
Yes. Our Service, Repairs & Maintenance unit provides scheduled servicing or SLA packages for any installed power, air or water system, ensuring optimal uptime and warranty compliance.
Absolutely—our portfolio ranges from family homes to warehouses, retail stores, pharmaceutical distribution centres and corporate campuses.
Typical project guarantees include 25 yrs (80 % output) on solar panels, 12 yrs on panel defects, 5 yrs on inverters, 10 yrs on batteries, and 12 months labour; evaporative coolers carry 12-month unit & labour cover.
