NEWS: Today LOGSTOR measures and checks the lambda value of our daily production continuously.
On the basis of these many measurements it is possible to calculate the average lambda value of each product.
When sufficiently many measurements have been carried out, the lambda value of each product will be changed.
So far the lambda value of axial conti pipes has been changed from 0.024 W/mK to the average lambda value 0.023 W/mK.
The average lambda value of traditionally manufactured pipes remains 0.027 W/mK.
LOGSTOR
Calculator is an Internet-based calculation program, designed to help energy
suppliers, consulting engineers, researchers, teachers and students to estimate
the most efficient transport of hot and cold water through pre-insulated pipes.
With LOGSTOR Calculator we give our existing and future customers the best possible
tool for evaluating and choosing the optimum pipe systems, ensuring establishment
of energy efficient and environmental friendly infrastructures.
LOGSTOR Calculator is the most accurate energy loss
calculation program, based on comprehensive mathematical and physical models in
order to obtain as correct heat loss calculations as possible. Only direct FEM calculations are more correct, but FEM
calculations are difficult to use.
Dependent on the market requirements and the needs of our
customers, in LOGSTOR Calculator they can choose between two calculation
principles:
·
Calculations based on
EN13941-based calculations
·
Advanced calculations, which
is an even more accurate program
In addition to heat loss calculation of each pipe, LOGSTOR
Calculator offers comparison of pipes and projects as regards energy loss in
volume and costs and CO2 emissions.
The insulation value is calculated as a function of
temperature and age.
All calculations and comparisons are illustrated both in
values and graphs, which give a quick and easy overview. LOGSTOR Calculator
also offers graphs of PUR foam ageing in different LOGSTOR pipes, based on
calculations from the Danish Technological Institute (www.dti.dk).
LOGSTOR Calculator is a simple and easy-to-use calculation
tool, where the focus is on the user's requirement to quick, effective and
factual knowledge.
