Chilled Water Line Insulation

Chilled water lines are often insulated with the sole objective to prevent condensation.

Chilled water line insulation.

40 c through 75 c i e. 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. View more view all jump to. Our systems are perfectly aligned with that objective and there s a lot more to be won too.

Piping that carries water at below ambient temperatures creates a strong vapor drive toward the pipe. Replacement cost around 25 million. Cellular glass glass fiber phenolic foam and polyurethane foam are popular materials for insulating chilled water pipe. Cooling and chilled water insulation.

Failures start with design and can be aggravated by poor installation and maintenance hart explains. 5 c through 0 c i e. The glass fiber insulation gained from 400 to almost 700. Cold or chilled water.

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. 0 c through 40 c i e. For the polyurethane the heat transfer has increased almost 300. 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.

As tests i recently concluded confirm in hot humid climates there are significant differences in thermal performance over time between them. Chilled water pipe insulation insulation is a critical component in chilled water systems. Pre slit and pre glued with overlap nbr pvc pipe insulation. Chilled water pipe insulation is the wrong place to attempt value engineering when designing new or replacement piping.

Low temperature thermal insulation 1. 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. Pipe insulation fits around hot water pipes and reduces heat loss to save energy and lower energy costs. 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.

For insulating chilled water piping systems in mechanical systems using a vapor sealed mineral fiber pipe insulation. Pre slit polyethylene pipe insulation. Hinged with self sealing lap fiberglass pipe insulation. Thermal insulation is further divided into three general application temperature ranges as follows.
