KTI - SAUTER hot water concrete heater (HWS)

The KTI - SAUTER hot water systems (HWS) are used in the production of concrete, especially winter concrete. They heat mixing water to 40 - 60 °C under winter conditions without any problems.

Plant information

The KTI - SAUTER hot water units are tailored to the requirements of all common concrete mixing plants in terms of system performance and hot water volume. The robust design with a Stainless steel boiler as well as a high performance insulation guarantee 100% performance for years. Hot water system boilers are not classified as pressure vessels, as is the case with commercial water heaters. As a result The annually recurring inspections are omitted - this reduces ongoing operating costs. All hot water systems are available as stand-alone, independent units for installation in buildings or as containerized solutions. They are equipped with LO-NOx burner equipped with different fuels can be operated - biodiesel, biogas are available in addition to the classic fuels. Most often, a hot water system is used in Combination with a hot air unit (OLH) for heating the silos are installed together. However, both systems can always be operated independently, as required.

Two installation possibilities offer special advantages

Direct installation In the direct installation, fresh water supplied as required is heated and consumed. As the KTI - SAUTER hot water system heats water without pressure, a water feed pump is installed to feed the hot water directly into the concrete mixing plant or to the truck mixer. A essential advantage of this design is that no additional water-to-water heat exchanger needs to be installed. The Total energy in the water can therefore be used.   Indirect installation Indirect heating of water by means of a heat transfer station provides the AdvantageThe water pressure of the public sewer system is used to supply the mixing plant or truck mixer with the water to be added. An indirect installation consists of a closed heating circuit between the hot water system and a so-called transfer station. Due to the closed heating circuit, there is almost no contamination of the heat exchangers in the installation. This has a positive effect on maintenance costs. The circulating pump installed in this system requires only about 10 % of current of a hot water feed pump as used for direct installation. The only drawback is the loss in the transfer station.   The direct and indirect installation variants can be supplemented by additional heat exchangers for a space heating system or other applications.be expanded.

KTI - Insight

The HWS hot water system is a "must-have" for all those who want to heat up addition water for concrete production in winter. The HWS is very easy to operate and very flexible to use. The stainless steel boiler is on the one hand very durable, as no corrosion can occur, and on the other hand the pressureless water supply saves the annual inspection by the TĂśV. In the long run, both of these factors benefit maintenance and operating costs.
Often the HWS is used together with our air heater OLH as a package. My customers receive two independently running plants. This means that only one unit can be operated in the off-season. If it gets even colder, the other unit can simply be switched on.
