O&L Leisure is well known for their high-quality lodges and hotels. Guests all over the world expect the best standards, which start with flawless bed and table linen and toweling with a soft handle. Carefully selected and exquisitely finished laundry is good advertising for hotel standards. And, at the same time, laundry care is a significant investment. It is therefore all the more important that hotel laundry is long-lasting and durable, underlining care and attention to perfection.

CTS designed and installed the full turn key solution for Strand Hotel, which included Miele washers, tumblers and drying ironers, as well as various accessories, including a form finisher. Miele professional machines are custom-made to meet the individual needs, and they offer the perfect solution with optimum economy.

Strand Hotel can now pride themselves with a state of the art laundry. CTS, a complete service from just one source.

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.

CTS ensures that your system is designed for your requirements.  With our years of experience, we not only install, but also service and maintain the equipment today, and in the years to come.

With our extensive knowledge in sterilization and infection control, CTS installed suitable autoclaves with BSL3 seals.  In addition to the autoclaves, an effluent treatment system was also installed.  This system collects the effluent from the autoclaves, sinks and wash basins, and collects it in one tank.  Once a certain level has been reached, a second tank will collect the effluent, while sterilization begins in the first tank.  In this way, collection of the effluent is not delayed whilst sterilization is being performed in one of the tanks.  Through this system, the highest level of decontamination is achieved, ensuring a safe environment.

CVL is classified as a BSL 3 laboratory.  BSL 3 means a biosafety level of 3.  This is a level of bio-containment precautions, required to isolate dangerous agents, which may cause serious diseases.  This includes various bacteria, viruses and parasites.  CVL required autoclaves with a BSL3 seal approval, as well as an effluent treatment system, to decontaminate a wide range of aqueous liquids.

CTS was awarded the tender to supply, deliver to site, installation, testing and commission of two autoclaves and an effluent treatment system for CVL.

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.

Weather data can be found at: http://www.sasscalweathernet.org .

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)

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.
