Cold or chilled water.
Chilled water line insulation.
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.
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.
5 c through 0 c i e.
0 c through 40 c i e.
Cellular glass glass fiber phenolic foam and polyurethane foam are popular materials for insulating chilled water pipe.
Our systems are perfectly aligned with that objective and there s a lot more to be won too.

The glass fiber insulation gained from 400 to almost 700.
Cooling and chilled water 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.
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.
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.
40 c through 75 c i e.
Replacement cost around 25 million.
Low temperature thermal insulation 1.
Pipe insulation fits around hot water pipes and reduces heat loss to save energy and lower energy costs.
The cellular glass remained the same with no moisture thermal gain.
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.
Chilled water pipe insulation insulation is a critical component in chilled water systems.
For the polyurethane the heat transfer has increased almost 300.
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.
Piping that carries water at below ambient temperatures creates a strong vapor drive toward the pipe.
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.
For insulating chilled water piping systems in mechanical systems using a vapor sealed mineral fiber pipe insulation.
