The installed photovoltaic system at Elavi Clinic caters for the power supply to the clinic as well as the nurse houses. A 6.2kW PV module array generates enough power for the energy requirements. Should this not be sufficient the batteries can be charged by a backup generator.

The system consists of the following:

• 6.24 kW PV array
• 2x Victron BueSolar 150V/70A MPPT regulator
• 600Ah Battery capacity
• Inverter/Charger, Victron Multi, 48V/8000VA
• System Monitoring (BMV700, Color Control GX)

CTS was approached by a senior resident of Klein Windhoek to install a grid-tied photovoltaic system with the aim to cut back on the monthly electricity bill. The system included:

• 42x 130W photovoltaic modules and mounting structure
• 1x 6kW grid tied inverter

The system is designed such as to generate an estimated 900kWh per month.

Central Technical Supplies was approached by the University of Stellenbosch to take part in a tender to supply a solar resource measurement station to the Namibia University of Science and Technology in Windhoek.

We were successful in winning the tender. The station is based on the Kipp and Zonen Solys 2 sun tracker with CMP 10 Pyranometer and CHP1 Pyrheliometer.

The station is based on the CR1000 logger from Campbell Scientific and measures wind speed and direction as well as ambient temperature, humidity and rain in addition to the solar resource data.

CTS was awarded the tender in July 2011 for Katima Mulilo’s Hospital laundry. The scope of the work included the supply, manufacture and assembly, delivery to site, installation, testing, commissioning and maintenance of laundry equipment.

Safety is born of experience. In the field of clinical practice, medical know-how and professional laundry care ensure optimum treatment and care of patients. For this, systematic cleaning, disinfection, drying and sterilization of linen and operating garments are prerequisites for avoiding risk to both patients and staff.

Katima Mulilo’s Hospital has to process over 1 ton of laundry per day. Our high speed washer extractors have a spin factor of 830rpm, greatly reducing tumbling time. With built in soap dispensers, the correct amount of soap is used each time, and the perforated lifting ribs mean more mechanical action and lower water consumption. The high speed washers significantly reduce water and electricity consumption, and still ensure hygienically clean laundry.

Miele offer rotary ironers with roller diameters ranging from 210 to 500 mm. Aluminium heater plates instead of steel guarantee an excellent distribution of heat and considerably reduced heating up times. The foot control ensures that the roller can be easily stopped, eg. for steaming.

A pneumatic lifting device creates a high pressure ironing action for an excellent finish. Katima Mulilo’s Hospital has the largest Miele rotary ironers in Namibia.

A 71kW grid tied (Nampower ) PV system was installed at the Klein-Aus Vista Lodge just outside Aus. Remote Monitoring and Energy meter is included to obtain precise information about own consumption as well as exported power. This aids in future electrical reticulation upgrades and designs.

System Specifications are:

• 240 x 295W Canadian Solar PV modules
•  3 x Fronius Symo 20.0 – 3 Grid Inverter
• Shed roof mounting with structure for IBR roof sheeting
• AC & DC surge and Lightning protection
• Configured for remote monitoring

CTS was awarded the tender in February 2010 for Okankolo Health Centre’s laundry.

The scope of the work included the supply, manufacture and assembly, delivery to site, installation, testing, commissioning and maintenance of laundry equipment.

Health Centers have to ensure that their laundry is hygienically clean. Our washing machines have a special sluicing program, which is ideal for blood stained linen and operation gowns. After the sluicing program, washing resumes as normal at higher temperatures, ensuring that all bacteria are destroyed, leaving laundry clean and safe to be used again. Our washers can be equipped with a second drain valve to recycle drain water, making them environmentally friendly.

Using roller ironers further sterilizes the linen; ensuring optimum care is taken for patients as well as Health Center staff.
