CTS was awarded four tenders in 2015, to supply, deliver to site, install, test and commission of autoclaves throughout Namibia.

In addition to the 160L Steri Tech autoclaves, water softeners were installed to increase the life span of each unit and reduce overall maintenance cost.

A number of installation teams worked hard to complete the project within the stringent timeframe set by the client. Each site came with its own challenges such as:

1. Removing of existing units that were beyond repair
2. Low supply water pressure
3. Space limitations where the new units were to be installed
4. Breaking out of walls to fit new autoclave
   

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.

Based on our excellent service and knowledge we have rendered to the Botswana Meteorological Department as well as University of Hamburg, CTS was able to secure the 2nd Phase of the manufacture, supply and installation of automatic weather stations in Botswana.

The stations supplied to make use of satellite communication due to the extreme remoteness of the sites, these were:

• Mababe (Savuti Marsh)
• Tubu (Okavango)
• Baines Drift (Eastern Botswana)
• Xade (Central Kalahari Game Park)
• Ngwaltle (Western Botswana)

These stations are not located at any Meteorological Department property, thus fences had to be erected for protection against animals.

Station design is based on our well proven tripod mast with all relevant sensors and a CR1000 logger as the processing unit. Data is transmitted at fixed timeslots allocated by EUMETSAT (Germany) on an hourly basis. Satellite transmission is based on a fire and forget principle, thus no remote maintenance can be done.

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 successful in winning the tender for the refurbishment of the transformer oil storage plant at the van Eck Power station. The project included the following:

1. Cleaning and painting of all oil tanks
2. Automating the entire plant
3. Installation of oil filtration system

Old as well as new transformer oil is stored in different tanks. Color codes on the tank clearly indicate what type of oil is stored in each tank. Old oil – oil removed from transformers during service – is stored until enough has been collected before it is sold.

Clean/new oil is stored in the other thanks that will be used for refilling transformers during routine services. Humidity tends to form inside the oil when it is stored for longer periods. This humidity as well as other dirt particles are removed my means of the Alfa Laval Oil Filtration plant. The process is fully automated and PLC controlled. The operator merely is required to enter the quantity of oil that is to be filtered.

Radar level sensors are installed in each tank to monitor quantity on hand. Maintenance free breathers on each tank prevent access of water moisture into the tank and the buildup of dangerous gases.

A Coriolis custody transfer meter accurately indicates the quantity of old oil the is transferred to third party tankers for selling purposes.
