Supply of Solar Resource Measurement Station to NUST

Namibia University of Science and Technology

2016

Central Technical Supplies was approached by the University of Stellenbosch to take part in a tender to supply a solar resource measurement station to the Namibia University of Science and Technology in Windhoek.

We were successful in winning the tender. The station is based on the Kipp and Zonen Solys 2 sun tracker with CMP 10 Pyranometer and CHP1 Pyrheliometer.

The station is based on the CR1000 logger from Campbell Scientific and measures wind speed and direction as well as ambient temperature, humidity and rain in addition to the solar resource data.

Installation of new Steam Boiler at Hartlief Windhoek

Hartlief

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

Installation of Containerized Off-Grid PV Systems in the Otjozondjupa Region

Ministry of Mines and Energy

2015

Three localities in the Otjozondjupa region where successfully electrified by means of Off-Grid PV containers. The system sizes varied from 6kW, 12kW to 25kW of PV power. PV modules where installed on roofs of nearby houses, batteries, inverter/charger and switchgear are located in our proven design of prefabricated containers to keep the components cool, even in the hottest of climates.

The system is an AC coupled PV system with SMA Sunny Island (SI 8.0) inverter and SunnyBoys of various sizes. Communication between all components is based on a wireless RS485 solution from Phoenix Contact with a distance covered of 1.5km.

Sites that were electrified in the Otjozondjupa region are:

Rooidag Hek
M’Kata
Kukurushe

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.

Installation of 26 Autoclaves Country Wide

Ministry of Health and Social Services

2015

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:

Removing of existing units that were beyond repair
Low supply water pressure
Space limitations where the new units were to be installed
Breaking out of walls to fit new autoclave
