CTS was approached by the Botswana Meteorological Department and the University of Hamburg with the request to install automatic weather stations across Botswana. A total of 10 stations were engineered and build at our workshop in Windhoek prior to installation commencement. With our own tower design, the installation time is reduced to nearly 8 hours per tower.

The stations are equipped with sensors from Vaisala, Kipp and Zonen. At the heart of each station is the CR1000 logger from Campbell Scientific. Each station is capable to measure the following:

• Wind speed
• Wind direction
• Humidity
• Air Temperature
• Irradiance
• Barometric pressure
• Ground Temperature
• Rain
• Leaf wetness

In addition to the above parameters the following parameters are calculated by the logger by means of mathematical models.

• Dew point temperature
• Wet bulb temperature
• Sunshine duration

The data from the station is transmitted to ftp servers situated in Gaborone/Botswana as well as Hamburg/Germany on an hourly bases over locally available GSM network providers. Once the data is uploaded to the server in Hamburg, it is processed and posted on a publicly available website. This website collects data of numerous stations across Namibia, Botswana, Zambia, Angola and South Africa for research purposes. A total of 8000km was covered in just under 4 weeks.

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.

CTS was instructed to supply, deliver, install, test and commission laundry equipment for the Mine Complex Change House, Plant Complex Change House and the FPR Change House at the Husab Mine in 2015.

The Husab mine has to process nearly 2 000 overalls and towels on a daily basis. Emphasis was made on equipment that is energy efficient, safe to operate and cost effective to maintain.

Miele equipment fulfills every requirement when it comes to the economical processing of large amounts of laundry. Miele’s tried and tested programs ensure the correct washing process for every type of material. The tumble driers complement the washer extractors and are highly economical, thanks to short running times. Thus you have a perfect solution to process large amounts of laundry, fast, hygienically and economically.

CTS installed washer extractors fitted with water recovery units and heat pump tumble driers. Laundry-care requirements vary significantly according to the customer’s needs. Whichever your requirement, CTS can offer you the ideal solution.

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.

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.

DeBeers Namibia published a tender for the supply and installation of a weather monitoring system at the Oranjemund Airport. CTS was awarded the tender based on price, knowledge of the meteorological measuring equipment as well as quality of products. At time of installation the station was the most advanced aviation weather station in Namibia.

Technical Details of the system installed:

• Ceilometer at end of runway 20 to measure cloud height at three levels up to 7,500m
• Runway Visibility and Present Weather sensor at stop end of runway 20.
• Present weather sensor monitors 7 different types of precipitation
• visibility sensor takes background luminescence into account
• Wind speed and direction a touchdown runway 20.
• Wind speed and direction, rain as well as barometric pressure at stop end runway 20
• AviMet server for processing of all data
• 3 workstations spread along the buildings for weather monitoring and supervision purposes
• ATIS voice system transmitting on aviation frequency as well as telephone dial in the current weather conditions

All communication between the equipment and the AviMet server is based on wireless transmission to reduce cabling costs.

The weather information can be picked up rough 100 NM away from the airport by all approaching aircraft.
