Tubular Heaters Maintain Oil Temperatures During Downtime Or Prior To Startup
Process Heating Co., based in Seattle, WA., has developed rigid tubular heaters. These heaters are used as part of a paper machine lube oil system and in hydraulic reservoirs to maintain oil temperatures during downtimes for maintenance or to increase oil temperatures to a workable point prior to startup.
The heaters can be installed as new or as replacement equipment for existing Calrod-style tubular units; the Calrod units are of higher-watt density and can result in oil choking. Process Heating's rigid heaters allow ease of replacement; they do not require machine downtime when being replaced. Furthermore, time-consuming oil draining is not required, and the heaters' low-watt density protects oil from damage. Rigid units of this design allow the heating elements to be equally spaced across the base of the reservoir for even heat distribution.
