Ra-Sha has been in business for more than 15 years and is an installation company specializing in new installations, expansions and the maintenance of your existing systems, such as water, gas and sanitary, boilers, heaters and pressurized water systems. We also do servicing of boilers and pumps.
We are located at Kwattaweg 427, Paramaribo – Suriname.
Our country has a widespread network of pipelines for the transport of water and gas to the customer. The growing demand for energy and the increased use of (drinking) water requires that new pipeline networks have to be built. Network administrators and contractors are therefore confronted with high quality and safety standards. It is here that Ra-Sha will make a huge difference, because for many years we already have only qualified and certified personnel working on our installations. We also make sure that our installers are continuously educated in the use of the most recent techniques and familiarize themselves with the newest products and materials on the market.
Ra-Sha is an independently owned entity. We want our business to increase and be more successful. This will be achieved by delivering quality work and materials to our customer base. We firmly believe that a happy and satisfied customer is the best advertisement that one can ask for and that is where our strength is. Because we are the official dealer of COMISA products for Suriname and the Caribbean, a healthy collaboration with our competitors and others in the branch will only help to strengthen our position in the market. The COMISA line of products are durable and of high quality and the benefits for the Surinamese market are almost immediately recognizable. Because the multilayer pipes and fittings will replace the copper pipes and fittings, there will be less copper theft, and the installations will last much longer so that the need to replace parts will be reduced.
We operate as follows. First we will meet with you, our prospective client/ customer, where we will discuss your needs and the possibilities. Shortly thereafter, we will make an offer and discuss it with you. After an agreement has been reached, we will turn our focus to making the drawings for your systems. If necessary, these drawings will be submitted to the appropriate government agencies for approval. Afterwards we will make an appointment with you regarding the new installation, expansions or maintenance.
Gas: We carry out all the activities from the gas distribution pipelines to the gas connection.
Water:We install all pipelines from the water mains to the water meter.
Sanitary: We carry out all sanitary work, including the installation and connection of toilets, sinks and valves.
Ra-Sha’s target audience consists of individuals, businesses and the government. Our current clients include big companies like Hurricane Steel, De Schuilplaats and Arquitecma. But we are also working with government agencies, small installation companies and individuals who build their own homes.
Our installers have all participated in GAWASALO training and are certified. Their competencies include: perseverance, commercial insight, flexibility, financial acumen, communication, collaboration, industry experience, experience of entrepreneurship, dealing with people, stress resistant, accounting insight and inventivity
COMISA MULTILAYERPIPE IN COILS FOR HOT AND COLD WATER ( 100 MTR/ COIL) 16X2 – 20X2 – 26X3
The COMISA multilayer pipe is a product of the latest generation
produced with advanced technology in the treatment of
polyethylene polymers and unites the advantages of a plastic
pipe and those of a metal pipe.
The COMISA multilayer pipe is flexible and robust, resistant
to high pressure and high temperatures.
The COMISA multilayer pipe is produced using a state of the
art technological production process.
1. The internal layer in polyethylene is extruded (A);
2. A first adhesive layer (Primer) is applied
to the external surface (B);
3. During the subsequent phase, an aluminium sheet
is wound around the pipe, butt-welded
and calibrated (C);
4. A second adhesive layer is applied
to the external surface of the aluminium layer (B);
5. A new external polyethylene layer is applied (D);
The entire production cycle occurs at constant and controlled
temperatures, is totally automated and includes five subsequent
and independent control points. Before the storage phase
the product is again controlled by specialised technicians to
guarantee the total qualitative level of the product.
The Comisa SOLARCOM solar thermal systems provide an
immediate return on the investment and demonstrate the strong
commitment for the environment. They are versatile systems,
designed to cover the needs of every type of application.
The natural circulation systems are the simplest and cheapest
system solution to produce domestic hot water.
They are small solar systems with single and double glazed
The coverage provided by the natural circulation solar thermal
can reach, on average, up to 70-80% of the annual domestic
hot water. The remaining water will then be produced with the
FORCED CIRCULATION SOLAR SYSTEMS
The solar collectors, usually placed on the roof, turn the solar
radiation into thermal energy. With the help of the heat transfer
fluid, namely a solution of glycol and water that circulates in
the pipes, the energy is transferred to the boiler. During the
heating, the heat of the heat transfer fluid is transferred to
the domestic water through the use of a heat exchanger. The
cooled fluid returns to the solar collectors where it is heated
again by closing the loop. An adequate automatic control system
monitors the proper operation of the system. A properly
sized system installed is able to reduce the costs associated
with the consumption of hot water up to 80 % in one year.
