Ministry of Agriculture through, through SASSCAL funding, did acquire 3 automatic weather stations in 2018 which where finally installed in 2019 after sites have been determined. These stations from part of the existing SASSCAL weather station network that has been established over the past years. All stations conform to SASSCAL requirements and are inline with WMO standards.

The stations are installed at :

• Dudukabe (Zambezi)
• Okalongo (Ohangwena)
• Omafo (Ohangwena)

Station info can be obtained from www.sasscalweathernet.org

Various small off-grid PV systems, also referred to SHS (Solar Home Systems) have been supplied country wide. These systems are typically based on small high efficiency lithium ion batteries as storage solution and Victron components such as solar charge regulator, inverter and monitoring devices.

When A La Mer Hotel in Swakopmund decided to expand, they approached CTS with a unique challenge: to create a functional laundry that was both energy and water efficient, and would also fit into a small space, while being whisper quiet, so as not to disturb any guests. In addition, the laundry has to perform excellently, producing quality wash, tumbling and ironing results. Only one brand came to mind: Miele.

Miele recently launched new bench mark machines, which have short program cycles, excellent spin performance, a redesigned patented honeycomb drum and have low consumption values. A La Mer Hotel was the first in Namibia to purchase these new machines.

CTS installed washer extractors with water recovery units, as well as automatic dosing systems, to ensure the best quality wash, every time. The tumble drier has an air recycling system, saving up to 60% of energy. And with a matching drying ironer, optimum finishing results are achieved. Small accessories made this laundry a complete turn key solution.

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
   

A modern hot water plant was installed based on heat pump technology. Stiebel Eltron storage tanks as well as heat pumps are supplied that are extremely energy efficient and long life expectancy while at the same time low on maintenance. Further energy savings are achieved as the system is connected to heat recovery units as part of the refrigeration plant.

The challenge of such a system is to guarantee even loading and unloading of the tanks with water to guarantee a uniform temperature distribution in all tanks. This has been achieved by careful piping planing based on the Tichelmann principal.

The system comprises of the following:

• 6x 1000 L buffer tanks
• 2x 23kW heat pump units.
• various pumps and control unit

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.
