Central Technical Supplies was once again awarded the tender to electrify 4 remote localities in the Otjozondjupa Region of Namibia. Custom build containers where installed on site with SMA Sunny Island 8.0 inverter installed. In addition the offered lead acid battery technology has been replaced by state of the art lithium batteries reducing system maintenance. The use of AC coupled technology did allow for the SunnyBoy solar inverter to be in installed inside relevant buildings on which PV modules are mounted. All components are interlinked by means of wireless technology to allow for remote monitoring where GSM signal is of sufficient strength. System sizes vary form 3kW, 12kW, 15kW to 20kW of PV power while inverters are as much as 3 in a single phase cluster.

Sites that were electrified are:

• Nhoma
• Aasvoel Nes
• Kanovlei
• Grashoek

CTS was instructed to supply, deliver, install, test and commission laundry equipment for Lady Pohamba Private Hospital in 2015. Situated in Windhoek’s Kleine Kuppe area, this new and stunning 134-bed hospital caters for a wide variety of patients.

When it comes to Hospital textiles, cleanliness and perfect hygiene is of the essence. The challenge is to safely wash large quantities of used and soiled fabrics, while ensuring consistent, hygienic cleaning, maximum longevity and shortened wash times. As Namibia is facing a water crisis, special attention needs to be given to using as little water as possible. Our solution was Miele.

Miele offers a wide range of machines with cutting edge technology and specialized wash programs. With their patented stainless steel Honeycomb Drum, the specially designed drum ribs allow the water to saturate the laundry very quickly, reducing washing times. The high spin speeds with a G-factor of up to 500 make for optimum water extraction. There are also connections for detergent dispensers, ensuring that the same amount of detergent is used for each wash. A water recovery unit saves up to 30% of the water consumption. The tumble dryers are equipped with a heat-pump system, with results in a reduction of 60% of energy consumption.

Thanks to the residual moisture level of approximately 50% achieved by Miele’s washer-extractors, bed linen does not need to be dried any further before it is fed into a rotary ironer with a high heat output. Miele’s technology guarantees economy and quality, and actively contribute towards protecting our health and environment.

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 approached by a senior resident of Klein Windhoek to install a grid-tied photovoltaic system with the aim to cut back on the monthly electricity bill. The system included:

• 42x 130W photovoltaic modules and mounting structure
• 1x 6kW grid tied inverter

The system is designed such as to generate an estimated 900kWh per month.

National Botanical Research institute approached CTS to upgrade two of their existing AWS to satellite communication and subsequent installation at Kanovlei in the Tsumkwe Area as well as Koichab Pan close to Lüderitz.

Communication is via Meteosat satellites and based on a “fire and forget” principal which unfortunately does not allow remote maintenance procedures.

The stations form part of the SASSCAL Weathernet and measure all important meteorological parameters.

Weather data can be viewed at: www.sasscalweathernet.org 

The University of Hamburg approached CTS directly with the request to quote and subsequently manufacture and install 3 automatic weather stations at:

• Khorixas
• Kaoko Otavi
• Okangwati

Once again, satellite communication has been chosen, this time not because of GSM not being available, but to reduce future cost of the stations as satellite communication for these stations has got no costs associated.

In addition to the basic data measured:

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

The stations are equipped with a WLAN interface. This allows the connection of 49″ SmartTV to be connected to each station to display the current weather inside close by offices.
