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 line insulation.

Our systems are perfectly aligned with that objective and there s a lot more to be won too.
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.
Replacement cost around 25 million.
Chilled water pipe insulation insulation is a critical component in chilled water systems.
Failures start with design and can be aggravated by poor installation and maintenance hart explains.
Low temperature thermal insulation 1.
40 c through 75 c i e.
Thermal insulation is further divided into three general application temperature ranges as follows.
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.
For the polyurethane the heat transfer has increased almost 300.
The glass fiber insulation gained from 400 to almost 700.
Hinged with self sealing lap fiberglass pipe insulation.
0 c through 40 c i e.
Pre slit and pre glued with overlap nbr pvc pipe insulation.
Cellular glass glass fiber phenolic foam and polyurethane foam are popular materials for insulating chilled water pipe.
The cellular glass remained the same with no moisture thermal gain.
Cooling and chilled water insulation.
Chilled water pipe insulation is the wrong place to attempt value engineering when designing new or replacement piping.
Premium condensation prevention with added bonus.
5 c through 0 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.
Piping that carries water at below ambient temperatures creates a strong vapor drive toward the pipe.
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 lines are often insulated with the sole objective to prevent condensation.
As tests i recently concluded confirm in hot humid climates there are significant differences in thermal performance over time between them.
Pre slit polyethylene pipe insulation.
Pipe insulation fits around hot water pipes and reduces heat loss to save energy and lower energy costs.
