Healthcare


Use of modern, high quality RU-FLEX thermal insulation avoids major problems: heat loss in hot water and heating systems, condensation and frost formation on cold water pipes and air-conditioning systems. Application on air ducts improves incoming air quality and reduces equipment noise.

Use of foam rubber products in healthcare facilities is approved by hygienic certification.

A wide range of application temperatures, low vapour permeability, absence of moisture saturation and, as a consequence, stability of thermal technical characteristics allow RU-FLEX foam rubber thermal insulation to be used for cold supply and cryogenics in medical institutions. Certified materials are recommended for use in buildings with the highest environmental requirements.

To help choose the right RU-FLEX ECO PHARM insulation thickness, we have prepared ready-made solutions (basic calculations).

Problem and solution

Calculation of insulation thickness to prevent condensation from ambient air on the thermal insulation cover layer.

Initial data

  • Heat transfer medium: propylene glycol
  • tm = 7 ˚С – coolant temperature in the pipe;
  • tокр = 20 ˚С – temperature in the shopping center;
  • φ = 65 % — the relative humidity in the shopping centre.
