Chilled Water Line Insulation

For the polyurethane the heat transfer has increased almost 300.

Chilled water line insulation.

Replacement cost around 25 million. The glass fiber insulation gained from 400 to almost 700. 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. 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.

Chilled water lines are often insulated with the sole objective to prevent condensation. 5 c through 0 c i e. Premium condensation prevention with added bonus. 0 c through 40 c i e.

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. As tests i recently concluded confirm in hot humid climates there are significant differences in thermal performance over time between them. Low temperature thermal insulation 1.

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. Thermal insulation is further divided into three general application temperature ranges as follows. Cellular glass glass fiber phenolic foam and polyurethane foam are popular materials for insulating chilled water pipe.

Chilled water pipe insulation is the wrong place to attempt value engineering when designing new or replacement piping. Pre slit and pre glued with overlap nbr pvc pipe insulation. Piping that carries water at below ambient temperatures creates a strong vapor drive toward the pipe. Cooling and chilled water insulation.

Our systems are perfectly aligned with that objective and there s a lot more to be won too. Pipe insulation fits around hot water pipes and reduces heat loss to save energy and lower energy costs. 40 c through 75 c i e. For insulating chilled water piping systems in mechanical systems using a vapor sealed mineral fiber pipe insulation.

The cellular glass remained the same with no moisture thermal gain. 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.
