Our gwk engineers are passionate about developing technical solutions and this is what we as manufacturers want to prove in the area of cooling towers with our gvk/ghkv series. We see it as our task to understand the entire process of our customers. Therefore we have focused on quality and longevity for the products gvk/ghkv. The cooling towers are part of a central cooling tower system, supplied turn-key and regulated with a freely programmable microprocessor control system or programmable logic control. They are used for dissipation of excess heat from production systems with a higher temperature level and they operate on the principle of evaporation. This is an important consideration for environmentally conscious industries.

For forced cooling, Seifert electronic offers compact fan units in various performance classes. The variable fin spacing in the high-performance heat sinks ensures strong cooling during fan operation. In forced convection cooling, fans are required as separate sources of convection. To ensure optimal convection during fan operation, it is recommended to incorporate heat sink profiles. The fin spacing in heat sink profiles is particularly important, as increasing the surface area is key for forced cooling. To push this boundary further, we have continuously reduced the fin spacing in our profiles. Depending on the model, up to three fans per cooler are possible, which can optionally be equipped with pressure chambers for improved air guidance. Most heat sinks are already equipped with aerodynamically designed hollow fins. Additionally, air deflectors for air guidance are available for some heat sink profiles.

For applications involving very high currents and voltages, Seifert electronic provides heat sinks and mounting brackets designed to apply the appropriate pressure for optimal disc cell cooling. Presspack cells are employed in circuits where very high currents and voltages are present. In such scenarios, disc cell cooling is crucial for ensuring good electrical and thermal transfer. Achieving this goal primarily hinges on the connection between individual presspack cells and the heat sinks in disc cell cooling. This connection must be established with the clamping force specified by the manufacturer. With Seifert heat sinks and the accompanying mounting brackets, also known as clamping brackets, we offer professional equipment for maintaining the correct pressure in disc cell cooling applications. This ensures a high level of durability and robustness, contributing to an extended lifespan of the setup.

Seifert heat sinks are designed for both natural and forced cooling applications. From standard heat sinks to individually machined custom profiles, we offer the appropriate heat sink in the desired profile. The standard heat sinks from Seifert electronic GmbH are classic finned heat sinks, primarily intended for natural cooling. However, these heat sinks can also be utilized for forced cooling with airflow. Thanks to the extensive variety of profiles in our standard range, we can fulfill almost any heat sink requirement. From small transistor coolers to profile giants for IGBT cooling, measuring up to 900 mm in width, we provide the right profile for nearly every application. In addition to our standard profiles, we have access to open profiles, offering the possibility of further variations without incurring tooling costs.

CLEAN PROCESS WATER WITH GWK KU-PLANTS Water is one of the key elements in our daily life. It is a supplier of the most various requirements, also in the area of technical and mechanical production. Water is an excellent cooling medium. ku-plants from gwk utilise the cooling energy provided by water to carry away heat from production machines in the most troublefree and cost effective way possible. Removing side effects Fresh water from a well, from rivers and from other surface reservoirs is always saturated with oxygen and includes a large number of minerals and suspended particles which can block up the cooling channels in production units through corrosion or by producing deposits. ku-plants from gwk do not allow such problems to arise. A plate-type heat exchanger made of stainless steel separates the clean closed circuit that is used to cool the production from the natural fresh water circuit that is contaminated with all kinds of impurities.

A complete centralised cooling plant, including the required peripherals, can be set up in the absolute shortest possible time at the subsequent place of installation and is immediately ready for use by means of prefabrication and installation in a container. This way, the otherwise high investments for an operating building, the costs for installation and start-up of the plant are reduced. Container cooling plants almost have no limitations in terms of their capacity and variety of possible combinations. They are supplemented by peripheral systems such as water treatment and water preparation systems or compressed air compressors. A series of different cooling systems and the combined systems composed of these units are primarily available: Chiller Heat pump systems for heat recovery Cooling tower combined with a KU system as a closed, clean cooling circuit Air heaters for direct recovery of heat hermeticool-units hermeticool hybrid-units

Every industrial production requires energy in order to make products. Often, electrical or primary energy is induced as heat, used for operation and must then be dissipated, converted or destroyed. Our gwk process engineers analyse and calculate production processes and the overall thermal periphery with the objective of lowering the necessary energy by means of energy recycling, of reducing the energy requirement at the individual stations, of converting energy or using it several times and dissipating it sensibly. The result is considerable energy saving, which results in cost-cutting and contributes to preserving the environment.

AIR- AND WATER COOLED COLD WATER UNITS gwk chillers in the sklc series are air-cooled compact cold water units with integrated condenser gwk chillers in the skw series are water-cooled compact cold water units cooled with external cooling water These chillers are equipped with screw condensers; the power regulation of the capacity to be dissipated is continuous. Water-cooled cold water units in the skw series with low coolant content can be operated very efficiently and are preferably used when the available cooling water from gwk cooling towers, gwk free cooler systems or customer-provided supplies has a higher temperature level than required for the production process but is available inexpensively..
