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. -:pressure from vacuum up to 40 bar -:usable in temperatures -100 °C to 250 °C -:high heat transfer coefficient -:low logarithmic temperature differences -:compact design -:low weight compared to tubular heat exchangers -:low pressure drop -:good self-cleaning, due to high media velocities -:heat transfer surfaces 0.14 - 58m² -:suitable for parallel use -:good performance for gas, steam or fluid -:wide range of fittings and accessories -:construction for individual applications -:use as heat exchanger, condenser or evaporator

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. -:hygienic design -:high heat transfer coefficient -:high range of pressure variants -:suitable for high viscosity materials -:versions for varying space requirements -:construction for individual applications -:suitable for liquids containing solid matter -:usable in temperatures -200 °C to 600 °C -:design as required -:pressure drop as required -:good self-cleaning, due to high media velocities -:good performance for gas, steam or fluid -:use as heat-exchanger, condenser or evaporator -:low product flow times for sensitive products

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. -:1,584 variants CAV/H, Storage & NAV/H models -:capacity 2 to 5,000 kW per unit -:fan size up to 1,250mm -:horizontal or vertical airflow -:Eurovent certified -:compact design -:768 variants GAV Industrial model -:up to 14 single or dual-speed fans -:sound classes N,L,S & E (LpA 28 to 73 dBA 5m) -:weather & UV resistant coatings -:pressure rating for vacuum to 16 bar -:effective fin separation

The UniSystem range of heat-exchange equipment is designed to offer one-stop complete solutions in efficient heat transfer situations. The UniSystem WRG is leading technology, offering major savings, preventing energy being literally poured down the drain, released into the atmosphere or pushed out of a chimney - both environmentally and financially. Each system is individually designed as required. No two situations are identical, the demands of process as well as limitations of space vary from system to system, even within the same plant the UNEX expertise ensures the correct results for you. Many customers of UniSystem return for complete plant heat concepts and solutions. -:energy saving -:environmentally friendly -:dryer exhaust of up to 25% -:condensate recovery at the steam boiler -:use of high-quality UNEX heat-exchangers -:simple installation -:fast return on investment -:money saving -:waste water saving of up to 50% -:recovery from exhaust gas -:compact design, built around existing equipment -:proven in use around the world -:minimal maintenance -:possible "Green Grants"

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. -:pressure from vacuum up to 25 bar -:high heat transfer coefficient -:compact design -:selectable pressure drop -:heat transfer surfaces 0.8 - 600m² -:suitable for wide range of fluids -:construction for individual applications -:plate thickness 0.4 - 0.9mm -:usable in temperatures -20 °C to 155 °C -:low logarithmic temperature differences -:low weight compared to tubular heat-exchangers -:good self-cleaning, due to high media velocities -:suitable for parallel use -:wide range of fittings -:use as heat-exchanger, condenser or evaporator -:wide range of construction materials

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. -:pressure from 0 to 25 bar -:high heat transfer coefficient -:compact design -:good self-cleaning, due to high media velocities -:heat transfer surfaces 0.3 - 57 m² -:usable in temperatures -20 °C to 250 °C -:construction for individual applications -:low pressure drop -:low maintenance -:good performance for gas, steam or fluid

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. -:pressure from vacuum up to 80 bar -:high heat transfer coefficient -:compact design -:plate thickness 0.4 mm to 1.0 mm -:low pressure drop -:heat transfer surfaces 2-10,000 m² -:construction for individual applications -:low logarithmic temperature differences -:covers can be flanged or welded -:usable in temperatures -200 °C to 900 °C -:possible heat-transfer area 250 m²/m³ -:low weight compared to tubular heat-exchangers -:all weldable and pressable materials can be used -:good self-cleaning, due to high media velocities -:good performance for gas, steam or fluid -:use as heat-exchanger, condenser or evaporator -:low product flow times for sensitive products -:fully welded construction without gaskets
