Heat exchangers - Import export

UniTwist heat-exchangers are particularly suited to the demands of food, pharmaceutical and industries where absolute cleanliness is paramount. In extra demanding situations a UniScrape, self-cleaning version can also be supplied. Semi-fluids, pulps, liquids with particulate or sediment content and fibrous mass can be processed. The concentric tube system can be supplied in a variety of smooth, hard or dimpled finishes, depending on the process requirements. UniTwist can be designed to fit in confined and restrained areas, the ability to produce a coiled heat-exchanger is particularly appropriate for fitment around existing tanks. A variety of fixtures, fittings and connections are available depending on the requirements.

The UniWeld combines the advantages of conventional shell and tube heat-exchangers with spiral and plate heat-exchangers due to its design and construction. This mixed construction is based on the design of the heat-transfer channels, which are on one side in the tube design and on the other side in a plate heat-exchanger. UniWeld Hybrid exchangers utilise in this way the advantage of tubular heat-exchangers (high temperature, pressure resistant and solid construction) and plate heat-exchangers (high heat transfer, minimal space and low logarithmic temperature difference) in a compact system. Other advantage compared with gasketed plate heat-exchangers is the safe splitting of the 2 media at pressures up to 80 bar and between -200°C and +900°C.

The UniCompact is a very versatile heat-exchanger, suitable for use in wide ranging applications, including liquid, gas and steam. The sealed units require no maintenance and the robust construction and variety of materials ensure a long service-life. The choice and design of the right UniCompact for your requirements will be calculated for you by an expert at UNEX. Thousands of these heat-exchangers have already been supplied and are reliably in use around the world. Depending on your needs, the UniCompact can also be delivered with fixtures, fittings, connections and insulation.

For the condensation of refrigerants in commercial and industrial refrigeration systems. The condensers are suitable for outdoor installation and can be installed in residential and industrial areas according to the sound pressure levels. There is a selection of over 1,500 models with four different sound pressure levels and construction sizes, depending on the application. The condensers, available in stainless steel/aluminium, are suitable for refrigerants (Frigene) and ammonia (NH3), depending on application.

These high-grade steel plates are hard-soldered by means of pure copper / lead flux using the vacuum method to produce a compact unit. Hard-soldered heat-exchangers are pressure vessels. In order to meet the safety regulations for pressure vessels, each heat-exchanger is submitted to a pressure and a leak test. All products are designed individually for the appropriate application and manufactured accordingly.

High performance plate type heat-exchangers consist of a number of formed, sealable heat-exchange plates according to the respective requirements. The alternating pressed plates and channel spacing cause highly turbulent flow behaviour, optimal self cleaning effect and highest possible heat transfer. Use of high-grade materials such as titanium, titanium palladium, highly alloyed steels and even a UniCarb carbon/graphite version help ensure UniGasket heat-exchangers are extremely economical compared to other heat-exchanger types. The plates are clamped to a rack between frame plate and pressure plate by means of clamping bolts.
