CTS removed old and obsolete laundry equipment and installed new machines.

The installed equipment consisted of:

1. 2 x new Primus FS40 high speed washer extractors
2. 2 x Maytag energy saving tumble dryers
3. 1 x Miele through-feed drying ironers
4. inculding laundry trolleys, ironing trolleys and other small accessories
   
   

This is a typical photovoltaic (PV) medium scale farm system found on many farms around Namibia. Over the past three years this system grew in PV size from 350Wpeak to ~1200Wpeak.

System specs are:

• PV modules with a total capacity of 1220Wpeak
• 1200VA, 24V Inverter charger
• 40A Solar Charge Regulator
• 360Ah battery bank@24V
• Battery Monitor showing: state of charge (%), charging/discharging current (A), Battery Voltage (V) and time to go (h)
• Switchgear for submersible pump control

The PV modules are mounted on frames facing true north for optimal energy harvesting. During times of limited sunshine, especially the rainy season, battery charging can be increased by starting the generator. Should the AC load increase behind the inverter rating, the generator can support the system to cater for the increased load. No automatic generator start function is included.

Furthermore a second PV system for the Farm workers has been installed to cater for lighting and a TV.

• 2x 90Wpeak PV modules
• 20A Solar Charge Regulator
• 2x 105Ah batteries
• 350VA, 12V inverter

CTS was awarded the first ever containerized off-grid solar electrification tender for the Ministry of Mines and Energy beginning of 2013. This project entailed:

• Upgrading of all government building wiring as per national standard for 9 sites in the Omusati region
• Manufacture, supply and install container power units for these sites.

The power containers consisted of ca 2.8kW of PV modules installed on the roof as well as 3,000 to 4,500 Ah of battery capacity depending on site requirements. Five KVA inverter charger and two 70A Blue Solar Charge regulator all from Victron Energy complete the system.

With a total of nine containers, school, hostels and other government buildings were electrified. Each container was subdivided into two rooms for batteries and inverter technology respectively.

With our 36T/m crane truck CTS was able to transport the container to site, navigating through thick sand with ease.

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.

After close to 20 years of operation, the existing electrically heated hot water boilers were replaced. A modern, energy efficient system supplied by Stiebel Eltron was installed. The system comprises of the following:

2x heat pumps
5x 1000L hot water tanks (with electrical backup)
1x Control panel with remote monitoring and SMS alarm functionality.
2x booster pumps to feed the hotel with water during times when municipal supply is shut off

The installation has been achieved in a 3 week period. All works have been carried out with minimal interruptions to the hot water supply to the hotel. Remote monitoring of the plant in included to assist the client with possible troubleshooting, thus avoiding unnecessary trips to Lüderitz. SMS communication allows the quick reaction times of hotel maintenance personnel to act in cases of municipal water loss.

CTS was awarded the tender in February 2010 for Okankolo Health Centre’s laundry.

The scope of the work included the supply, manufacture and assembly, delivery to site, installation, testing, commissioning and maintenance of laundry equipment.

Health Centers have to ensure that their laundry is hygienically clean. Our washing machines have a special sluicing program, which is ideal for blood stained linen and operation gowns. After the sluicing program, washing resumes as normal at higher temperatures, ensuring that all bacteria are destroyed, leaving laundry clean and safe to be used again. Our washers can be equipped with a second drain valve to recycle drain water, making them environmentally friendly.

Using roller ironers further sterilizes the linen; ensuring optimum care is taken for patients as well as Health Center staff.
