Clamps directly on straight copper pipes ! Double seal construction withstands a vacuum of up to 1.3 x 101 Pa. Clamps direct on to a straight copper pipe eliminating unnecessary welding or flaring. Withstands a vacuum of up to 1.3 x 101Pa (when connected) making it possible to be used in leak testing, evacuation and refrigerant gas charge. Select from three standard types of seal materials to be used with fluids for air conditioner and refrigerator production lines. Many models to suit various pipe sizes. One lever operation simultaneously clamps and seals pipe. Double seal construction for tight fit on end and outside surface of pipe ensures excellent sealing and vacuum resistance.

Our patented material is highly suitable to produce foam moulds and RTM pressure injection moulds. Advantages: • Large volumes of more than 2500 kg can be cast in less than 45 min. • Good castability • Hardly measurable linear shrinkage • High temperature resistance • Demoulding process after approx. 90 min. (after adding the last backfilling compound) • Chemical adhesion to polyester or vinylester gelcoat • Immediately after the first mould half has cooled down, the second mould half can be prepared • Copper pipes keep the mould surface on a nearly constant temperature • Post-curing is not necessary ALWA MOULD D backfilling compounds are the fastest system on the market. For the surface you can chose between two gelcoats: 1) ALWA MOULD COAT This is a vinylester gelcoat that is especially suitable for high-end surfaces. It can be polished to high-gloss. 2) ALWA EPF 10 This is an epoxy gelcoat that is easy-to-use and is recommended for parts, where high-gloss surfaces are not needed

System press fittings from copper for copper pipes according to EN 1057 for drinking water and heating installations. SANHA®-Press copper system fittings are well-known for outstanding quality, easy to work with and offer the right solution for a wide range of applications.

The 20 kHz roll seam welding heads with up to 3KW power are particularly suitable for continuous welding of pipes, solar absorbers, or copper sheets. Thanks to the discshaped sonotrode, ultrasonic roll seams provide continuous welds without seam interruption.

System press fittings from copper and copper alloys for copper pipes according to EN 1057 for solar and high-temperature applications for compressed air. SANHA®-Press Solar system fittings  have red moulded sealing rings made from FKM.

The SANHA series 4000 and 5000 „SA“ consist of solder and transition fittings for copper pipes according to EN 1057 and EN 13348 for hard and soft soldering. All products are certified according to many national and international certification bodies. SANHA capillary solder fittings are manufactured from copper (Cu-DHP, CW024A  for moulded parts) and copper alloys CC499K (threaded parts, cast parts) and fulfill all requirements of BS EN 1254.
