Installation of new Steam Boiler at Hartlief Windhoek - Hot Water - Our Projects

Hartlief Date: 2012

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

Refurbishment of the Van-Eck Transformer Oil Storage Facility

Nampower

2015

CTS was successful in winning the tender for the refurbishment of the transformer oil storage plant at the van Eck Power station. The project included the following:

Cleaning and painting of all oil tanks
Automating the entire plant
Installation of oil filtration system

Old as well as new transformer oil is stored in different tanks. Color codes on the tank clearly indicate what type of oil is stored in each tank. Old oil – oil removed from transformers during service – is stored until enough has been collected before it is sold.

Clean/new oil is stored in the other thanks that will be used for refilling transformers during routine services. Humidity tends to form inside the oil when it is stored for longer periods. This humidity as well as other dirt particles are removed my means of the Alfa Laval Oil Filtration plant. The process is fully automated and PLC controlled. The operator merely is required to enter the quantity of oil that is to be filtered.

Radar level sensors are installed in each tank to monitor quantity on hand. Maintenance free breathers on each tank prevent access of water moisture into the tank and the buildup of dangerous gases.

A Coriolis custody transfer meter accurately indicates the quantity of old oil the is transferred to third party tankers for selling purposes.

Design, Manufacture and Supply 21 Automatic Weather Stations

National Botanical Research Institute (BIOTA)

2010

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.

Oranjemund Airport - Supply, Install and Commission of an Aviation Weather Monitoring System

DeBeers Marine Namibia

2015

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.

Hanns Seidel Foundation -Foundation - Electrification of 2 School in the Ohangwena Region

Hanns Seidel Foundation

2018

CTS has electrified two schools in remote northern Namibia funded by the Hanns Seidel Foundation with the aim to provide electricity for lighting, thus extending learning hours for learners well into the night. Both systems are based on BlueNova 4kWh lithium ion batteries, Victron Energy charge regulators and inverter technology. Remote monitoring is possible via the integrated Colour Control GX from Victron. Special attention has been given to the system configuration to prevent total battery shutdown. This is achieved by switching the inverter off at a predefined battery state of charge (typically 20%) and only reactivate the inverter once the batteries are charged beyond a predetermined threshold.

The systems where officially inaugurated by the Ambassador of Germany in June 2018.

Design, Supply and Install of a new Hot Water System for Lüderitz Nest Hotel

Lüderitz Nest Hotel

2019

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.
