Thermal insulation sleeves - reducing energy loss

The reduction of heat loss from technological equipment that is difficult to insulate by conventional insulation methods (valves, valves, flanges, etc.) can be achieved by using removable thermal insulation linings. These sleeves are able to reduce energy losses by up to 80% and provide significant financial savings to the operation.

Thermal insulation sleeves are made to measure according to the dimensions of the specific equipment. The advantage of the sleeves is very easy handling, which is facilitated by fastening with Velcro, laces or hooks. The operator thus does not need any special equipment for fitting or removal.

The high-tech fibreglass-based materials of which the covers are made do not break even with multiple handling and maintain stable thermal insulation properties throughout. These materials are water resistant, flammable and can withstand highly corrosive chemicals. The materials also do not induce static electricity (R˂ 10 -⁶Ω) and are therefore suitable for explosion hazardous environments (EX). Heat transfer requirements of the equipment can also be taken into account for the material.

Example of reducing the energy consumption of a fitting

• Size DN 150
• Approximate valve area 0.6 m²

With a price of 5 400 CZK and a price of 1 MWh of natural gas of 360 CZK, the savings are 7 956 CZK per year. The return on investment is 8 months.

Other features and benefits

• Function as acoustic insulation (reduce noise by 20-50 dB).
• Reduce NOx, COx, SOx emissions.
• Heat transfer coefficient λ = 0.04W/mK.
• Temperature resistance: -100 to 1200 °C (depending on material).
• Suitable for the food industry (depending on material).
• Can also be used in outdoor environments (depending on material).
