Secomak 632 Process Air Heater

Model 632 Process Heater (1 - 12kW)

The Model 632 heater consists of a single element assembly mounted inside a stainless steel tube which is enclosed in an insulate jacket. The jacket allows maximum heat transfer to the air stream while maintaining a low surface temperature. This makes the model 632 ideal for mounting in vulnerable areas or in enclosures containing other equipment. The inlet of the 632 is flanged and the outlet is either flanged or provided with a duct/hose adapter.

The Model 632 will give an outlet temperature up to 300°C and is available in loadings from 1 to 12kW. The inlet can be fitted with a thermal cut-out to protect the element in the event of the airflow becoming restricted. The model 632 is design to accept inlet air temperatures up to 250°C.

A variety of temperature controls are available, ranging from switching devices to provide fixed loadings through to systems to monitor and regulate the output temperature. A range of adapters are available to couple the Model 632 with a variety of Secomak fans.

Heat Transfer Curve

The following heat transfer curve can be used to specify the appropriate heater size. First, determine the required flow rate and heater outlet temperature, then read across the axes to find the recommended size. Please note, when using the heat transfer curves allowances should be made for losses which will depend on the distance from the heater outer and the degree of insulation.The Model 632 Heater is only available in sizes 1-12kW, please click here to view the heat transfer curves for larger loadings.
