A 7,3 kWp off-grid PV system was installed at the farm Heinrichsfelde in the Aus area with a Lithium-ion battery. The system is able to power an entire farmhouse. Remote monitorng and supervision is included.

System Specifications are:

• 24 x 305W Renesola PV modules
• 2x Victron MPPT 150/85
• 1x Victron Quattro 48/10000
• 1x BlueNova Lithium-ion battery 48V-24kWh
• Roof mounted with structure for IBR roof sheeting
• AC surge and lightning protection

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.

CTS was awarded the first ever containerized off-grid solar electrification tender for the Ministry of Mines and Energy beginning of 2013. This project entailed:

• Upgrading of all government building wiring as per national standard for 9 sites in the Omusati region
• Manufacture, supply and install container power units for these sites.

The power containers consisted of ca 2.8kW of PV modules installed on the roof as well as 3,000 to 4,500 Ah of battery capacity depending on site requirements. Five KVA inverter charger and two 70A Blue Solar Charge regulator all from Victron Energy complete the system.

With a total of nine containers, school, hostels and other government buildings were electrified. Each container was subdivided into two rooms for batteries and inverter technology respectively.

With our 36T/m crane truck CTS was able to transport the container to site, navigating through thick sand with ease.

A new 7,1kWp Solar Home System for Net Metering was installed at a private residence in Windhoek.

System Specifications are:

• Grid connected with Net Metering
• 24 x 295W Canadian Solar PV modules. Total 7,1kWp.
• 1 x Fronius Primo 8,2-1
• Roof mounted with IBR sheeting
• Remote Monitoring and Energy Meter.

CTS has electrified two schools in remote northern Namibia funded by the Hanns Seidel Foundation with the aim to provide electricity for lighting, thus extending learning hours for learners well into the night. Both systems are based on BlueNova 4kWh lithium ion batteries, Victron Energy charge regulators and inverter technology. Remote monitoring is possible via the integrated Colour Control GX from Victron. Special attention has been given to the system configuration to prevent total battery shutdown. This is achieved by switching the inverter off at a predefined battery state of charge (typically 20%) and only reactivate the inverter once the batteries are charged beyond a predetermined threshold.

The systems where officially inaugurated by the Ambassador of Germany in June 2018.

After close to 20 years of operation, the existing electrically heated hot water boilers were replaced. A modern, energy efficient system supplied by Stiebel Eltron was installed. The system comprises of the following:

2x heat pumps
5x 1000L hot water tanks (with electrical backup)
1x Control panel with remote monitoring and SMS alarm functionality.
2x booster pumps to feed the hotel with water during times when municipal supply is shut off

The installation has been achieved in a 3 week period. All works have been carried out with minimal interruptions to the hot water supply to the hotel. Remote monitoring of the plant in included to assist the client with possible troubleshooting, thus avoiding unnecessary trips to Lüderitz. SMS communication allows the quick reaction times of hotel maintenance personnel to act in cases of municipal water loss.
