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

O&L Leisure is well known for their high-quality lodges and hotels. Guests all over the world expect the best standards, which start with flawless bed and table linen and toweling with a soft handle. Carefully selected and exquisitely finished laundry is good advertising for hotel standards. And, at the same time, laundry care is a significant investment. It is therefore all the more important that hotel laundry is long-lasting and durable, underlining care and attention to perfection.

CTS designed and installed the full turn key solution for Strand Hotel, which included Miele washers, tumblers and drying ironers, as well as various accessories, including a form finisher. Miele professional machines are custom-made to meet the individual needs, and they offer the perfect solution with optimum economy.

Strand Hotel can now pride themselves with a state of the art laundry. CTS, a complete service from just one source.

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
   
   

National Botanical Research institute approached CTS to upgrade two of their existing AWS to satellite communication and subsequent installation at Kanovlei in the Tsumkwe Area as well as Koichab Pan close to Lüderitz.

Communication is via Meteosat satellites and based on a “fire and forget” principal which unfortunately does not allow remote maintenance procedures.

The stations form part of the SASSCAL Weathernet and measure all important meteorological parameters.

Based on our excellent service and knowledge we have rendered to the Botswana Meteorological Department as well as University of Hamburg, CTS was able to secure the 2nd Phase of the manufacture, supply and installation of automatic weather stations in Botswana.

The stations supplied to make use of satellite communication due to the extreme remoteness of the sites, these were:

• Mababe (Savuti Marsh)
• Tubu (Okavango)
• Baines Drift (Eastern Botswana)
• Xade (Central Kalahari Game Park)
• Ngwaltle (Western Botswana)

These stations are not located at any Meteorological Department property, thus fences had to be erected for protection against animals.

Station design is based on our well proven tripod mast with all relevant sensors and a CR1000 logger as the processing unit. Data is transmitted at fixed timeslots allocated by EUMETSAT (Germany) on an hourly basis. Satellite transmission is based on a fire and forget principle, thus no remote maintenance can be done.
