Cool. Cooler. HETCOOL®-plus.

Our HETCOOL®-plus copper tubes have made us a long-standing partner to heavy industry and the refrigeration, air conditioning and medical gas supply industries. KME Mansfeld is a long-established company based in Germany and we have the ability, knowledge and materials to fulfil the demanding specifications of these sectors. Copper can cope with cold effortlessly. When other materials begin to become brittle or porous, copper keeps on going and can withstand temperatures as low as -269°C without deforming. Copper is an outstanding low temperature material, which is why it is used especially often for refrigeration and air conditioning. Copper is the material of choice for most refrigerants; the exceptions are clearly defined and legally stipulated.

Germany’s Energy Saving Ordinance (EnEV) promotes an awareness of efficiency and the thrifty use of heat. KME Mansfeld supplies seamless copper tubes for refrigeration and air conditioning with factory-fitted heat insulation made of polyethylene foam and a durable, weather-proof external LDPE sheath. That means energy savings of approx. €150/m over bare tubing (basis: media temperature 0°C, ambient temperature 25°C, 8000 operating hours p.a., cost of heat €8). All HETCOOL® tubes are clearly inscribed so that they can be traced back to their manufacturer at any time.

Typical uses

Standard sizes are available straight off our warehouse shelves. HETCOOL® products come in specially made, standard-compliant, secure packaging. Our packaging guarantees retention of shape, ensuring that a product’s properties are preserved to the utmost after leaving the factory. Sealing plugs at either end ensure that the inside of HETCOOL tubes remains clean and sterile. Sea-freight packaging is something else we offer as standard. We can assess individual requirements provided they can be presented technically, and offer them for an extra charge.
