Building chilled water systems can experience wide variations in temperature and pressure that causes inconsistent results in data gathering and equipment operation.

Water Quality
Building chilled water systems often have chemicals and biocides added to the fluid to protect the HVAC systems. These chemicals may not be compatible with lab equipment or glassware. Also, tiny bits of metal and other debris from the degradation of the pipes are found in chilled water loops that can damage sensitive lab equipment.

The building chilled water loop will usually have an "auto-fill" system that makeup water that is lost due to leaks. This means that if a hose comes loose in the lab at night or on the weekend, the chilled water loop will continue to flood the space until the flooding is discovered. This flooding can result in extensive damage to equipment and electrical shock hazard to personnel.

Many building chilled water systems undergo season maintenance outages or even shut down during winter months. Having a backup cooling system for these outage periods is important to ensure continuous operation and emergency operation.

If any of these six factors are a concern, it's better to use a water-to-water heat exchanging system like the eVap for your laboratory.
