Chilled Water Line Insulation

For insulating chilled water piping systems in mechanical systems using a vapor sealed mineral fiber pipe insulation.

Chilled water line insulation.

Thermal insulation is further divided into three general application temperature ranges as follows. As tests i recently concluded confirm in hot humid climates there are significant differences in thermal performance over time between them. Piping that carries water at below ambient temperatures creates a strong vapor drive toward the pipe. Chilled water lines are often insulated with the sole objective to prevent condensation.

Failures start with design and can be aggravated by poor installation and maintenance hart explains. 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. 0 c through 40 c i e. Hinged with self sealing lap fiberglass pipe insulation.

5 c through 0 c i e. Low temperature thermal insulation 1. 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. 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.

Pipe insulation fits around hot water pipes and reduces heat loss to save energy and lower energy costs. Cellular glass glass fiber phenolic foam and polyurethane foam are popular materials for insulating chilled water pipe. Premium condensation prevention with added bonus. Pre slit polyethylene pipe insulation.

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

For the polyurethane the heat transfer has increased almost 300. 40 c through 75 c i e. Our systems are perfectly aligned with that objective and there s a lot more to be won too. View more view all jump to.

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