Drying is an absolute necessity to prepare polyesters for molding. Polyesters and other polycondensation polymers can absorb moisture from the air. If pellets are not dried, the moisture will react with the molten polymer at processing temperatures, resulting in a loss of molecular weight. This loss leads to lowered physical properties such as reduced tensile and impact strengths. Therefore desiccant dryers must be used to dry the pellets prior to processing in an injection molding...
Increasing demand for data processing and storage capacity has led to major companies investing in new facilities that provide web-based services to an ever-higher number of users. In these facilities, having the correct conditions – such as temperature and humidity – is vital for maintaining the equipment and securing operations.
Vaisala products are renowned for their unrivaled performance, reliable results, and low total cost of ownership. They also have an exceptionally long lifetime and excellent measurement stability. Because we are so confident in the lasting quality and long lifetime of our measurement instruments, we have extended the warranty period from two to five years for selected HVAC transmitters.
Many of Vaisala’s products and systems provide a major contribution in the fight against diseases, and in the following article we outline some of the ways that our measurement technologies are helping to end the COVID-19 pandemic.
Dew point temperature is a useful parameter in many industrial humidity applications. It is often used to measure dryness in applications such as plastics and compressed-air drying , where the relative humidity is typically below 10%RH. It is an industrial de facto to call these types of low humidity instruments as dew point meters. This is an ideal application area for Vaisala DRYCAP® technology.
