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.

A new 7,1kWp Solar Home System for Net Metering was installed at a private residence in Windhoek.

System Specifications are:

• Grid connected with Net Metering
• 24 x 295W Canadian Solar PV modules. Total 7,1kWp.
• 1 x Fronius Primo 8,2-1
• Roof mounted with IBR sheeting
• Remote Monitoring and Energy Meter.

An off gird PV system with generator back up was installed at the Gcwatjinga clinic south east of Rundu. The system comprises of the following components:

• 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)

The clinic was connected to the grid, which at time of system design and installation the grid connection plans were unknown to the engineer. As the clinic has PV installed, the existing system has been configured such as to allow for grid connection once the batteries reach a predefined SOC. This guarantees a continuous supply of power to the clinic and nurse houses.

In addition to the grid, a backup generator is incorporated in case PV as well as grid failure occur.

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.

A 71kW grid tied (Nampower ) PV system was installed at the Klein-Aus Vista Lodge just outside Aus. Remote Monitoring and Energy meter is included to obtain precise information about own consumption as well as exported power. This aids in future electrical reticulation upgrades and designs.

System Specifications are:

• 240 x 295W Canadian Solar PV modules
•  3 x Fronius Symo 20.0 – 3 Grid Inverter
• Shed roof mounting with structure for IBR roof sheeting
• AC & DC surge and Lightning protection
• Configured for remote monitoring

CTS was instructed to supply, deliver, install, test and commission laundry equipment for the Mine Complex Change House, Plant Complex Change House and the FPR Change House at the Husab Mine in 2015.

The Husab mine has to process nearly 2 000 overalls and towels on a daily basis. Emphasis was made on equipment that is energy efficient, safe to operate and cost effective to maintain.

Miele equipment fulfills every requirement when it comes to the economical processing of large amounts of laundry. Miele’s tried and tested programs ensure the correct washing process for every type of material. The tumble driers complement the washer extractors and are highly economical, thanks to short running times. Thus you have a perfect solution to process large amounts of laundry, fast, hygienically and economically.

CTS installed washer extractors fitted with water recovery units and heat pump tumble driers. Laundry-care requirements vary significantly according to the customer’s needs. Whichever your requirement, CTS can offer you the ideal solution.
