Chilled Water Line Insulation

The glass fiber insulation gained from 400 to almost 700.

Chilled water line insulation.

Piping that carries water at below ambient temperatures creates a strong vapor drive toward the pipe. The cellular glass remained the same with no moisture thermal gain. Chilled water pipe insulation insulation is a critical component in chilled water systems. Incorrect product selection or using untrained installers can cause a building owner s life cycle costs to increase by millions of dollars compared to the minor cost premium of correctly insulating the pipe.

5 c through 0 c i e. Cellular glass glass fiber phenolic foam and polyurethane foam are popular materials for insulating chilled water pipe. 40 c through 75 c i e. Pre slit and pre glued with overlap nbr pvc pipe insulation.

Hinged with self sealing lap fiberglass pipe insulation. In miami the cost of a chilled water system insulation job at an office building was 750 000 but hart noted that the system failed before the facility was even occupied. Thermal insulation is further divided into three general application temperature ranges as follows. Failures start with design and can be aggravated by poor installation and maintenance hart explains.

In other words ambient air which is at higher vapor pressure tries to push moist air toward the insulated pipe surface where vapor pressure is lower. Cold or chilled water. Replacement cost around 25 million. As tests i recently concluded confirm in hot humid climates there are significant differences in thermal performance over time between them.

This calculation determines the ideal thickness of water piping insulation for efficiently and economically preventing a heat transfer from outside to inside and keeping the water transported within cool it does not determine the thickness of insulation designed to keep condensate or other fluids from losing heat. For the polyurethane the heat transfer has increased almost 300. This test data shows that heat transfer through the pipe insulation into the chilled water system has increased by 400 in the glass fiber insulation. Premium condensation prevention with added bonus.

Chilled water lines are often insulated with the sole objective to prevent condensation. Pipe insulation fits around hot water pipes and reduces heat loss to save energy and lower energy costs. For insulating chilled water piping systems in mechanical systems using a vapor sealed mineral fiber pipe insulation. Cooling and chilled water insulation.

Pre slit polyethylene pipe insulation. 0 c through 40 c i e. The insulation system recommendations in this guide are intended for use on cold or chilled water piping systems operating from 33 f to 60 f 0 5 c to 15 6 c located within conditioned spaces in commercial and institutional.
