A La Mer Laundry - Swakopmund

for A La Mer Laundry

2017

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.

Supply and Installation of a Hot Water Plant at Ongwediva Meat Processing Facitly

Ministry of Agriculture

2020

A modern hot water plant was installed based on heat pump technology. Stiebel Eltron storage tanks as well as heat pumps are supplied that are extremely energy efficient and long life expectancy while at the same time low on maintenance. Further energy savings are achieved as the system is connected to heat recovery units as part of the refrigeration plant.

The challenge of such a system is to guarantee even loading and unloading of the tanks with water to guarantee a uniform temperature distribution in all tanks. This has been achieved by careful piping planing based on the Tichelmann principal.

The system comprises of the following:

6x 1000 L buffer tanks
2x 23kW heat pump units.
various pumps and control unit

Installation of 4 Containerized off-grid PV systems in the Otjozondjupa Region

Ministry of Mines and Energy

2019

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 In addition the offered lead acid battery technology has been replaced by state of the art lithium batteries reducing system maintenance.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

Supply and Installation of Laundry Equipment at Okankolo Heath Care Centre

Ministry Of Health And Social Services

2010

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.
