BIM stands for Building Information Modeling, which means building data modeling in German. It is a method of digital planning, execution and management of buildings. All relevant information about a building is recorded and managed in a digital model. This includes not only geometric data, but also information about materials, costs, schedules and other relevant aspects. BIM enables more efficient collaboration between all those involved in construction and better planning and control of construction projects.
District heating is the term for the delivery of heat to supply buildings with space heating and hot water. Thermal energy is transported in thermally insulated pipe systems, which are primarily laid underground.
The difference between local and district heating is generally a linguistic one. The term local heating is used to describe smaller, decentralised heating networks, whereas district heating refers to larger networks that generally have large transport pipes. Go to our district heating products.
The name refers to our low-temperature flexible pipe system. It is a combination of the Italian word calore (heat) and PEX. In our product range, the carrier pipe is made from PEX plastic (cross-linked polyethylene).
The name refers to the PUR foam, which is used in the CALPEX product range and ensures exceptionally low thermal losses. The lambda value is currently an outstanding 0.0199 W/m*K.
The lambda value describes the thermal conductivity of a material and is one of the most important values for assessing the suitability of a substance for energy-efficient construction and renovation.
The U value is a thermal transmittance coefficient used to specify the thermal insulation in pipe construction. The thermal transmittance unit is: W/m2K. This indicates how much heat (in watts W) per square metre (m2) flows through a component between the inside and outside for each degree of difference in temperature (in kelvin K).
Main types of insulated pipes for local and district heating
The insulated pipes needed for transporting hot water can be divided into two broad categories: rigid and flexible pipe systems. Both have their advantages and disadvantages, and the decision about which pipe system should be used in each individual case depends on the specific technical requirements.
Cryogenic media such as LNG (Liquefied Natural Gas) are used in various ways in the industry. LNG is often used as a fuel in heavy-duty vehicles and ships, as it has a higher energy density and produces fewer emissions than diesel fuels. It is also used as a fuel for power plants and for generating steam and heat in the industry. Additionally, cryogenic media such as liquid nitrogen and liquid oxygen are used for cooling machinery and equipment, as well as for storing materials that need to be kept at low temperatures, such as biological samples or food. Cryogenic media can also be used in the production of semiconductors and other electronic components to control temperature and improve product quality.
