A 1.5t boiler was installed at the Hartlief factory to cater for the growing needs of steam. The project included:

• Installation of new steam boiler next to the existing boiler
• Modifications to HFO line to cater for new boiler
• Commissioning

Over the past year's minor refurbishment, maintenance and upgrading projects where completed as well such as:

• Installation of condensate pumps to reduce back pressure of equipment inside the factory
• Raising current condensate storage tanks to increase head pressure for feed water pumps
• Three monthly service of both steam boiler and yearly inspection with Ministry of Labor inspectors
  

CTS has supplied 21 weather stations for the Biota research project. These weather stations are designed according to world meteorological standard.

Each station consists of:

• Wind Speed and Direction Sensor
• Irradiance Sensor
• Humidity/Ambient Temperature Sensor
• Barometric Pressure Sensor
• Ground Temperature Sensor
• Leaf Wetness Sensor
• Rain Bucket

The weather stations are equipment with the CR1000 logger from Campbell Scientific. Special software has been developed to allow automatic transmission of the weather data to a server based in Germany via GPRS using the local GSM network. Software updates can be done remotely minimizing travel.

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.

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 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.

CTS was awarded the tender to install a water heating system for the Hilton Hotel Windhoek.

The system was installed according to the following specifications:

•    2x 250kW gas fired hot water boiler

•    2x 6800 liter hot water storage tank (also known as calorifier)

•    1x Danfoss Aqua drive 11kW for glycol circulation pump control

•    2x Automatic bypass valves to control water temperature inside tank

•    4x Hot water circulation pumps

The boilers as well as glycol circulation pumps and one hot water storage tank were installed in the boiler room located in the upper basement of the hotel. The second hot water storage tank is installed on the 9th floor of the Hilton Hotel. A glycol circulation system connects the two calorifier with the two gas fired hot water boilers. The glycol circulation pumps are controlled from one Danfoss Aqua drive with cascading functionality to control the pumping speed depending on the temperature in the glycol line.

Each hot water boiler is cycled on a 24 hour basis, should the glycol temperature fall below a predetermined threshold for certain period of time the second boiler will start automatically.

Automatic bypass valves guarantee that the water temperature of each calorifier is kept at a constant 60 – 65 degrees Celsius.
