Dimensions and weight of customized configurations
Custom-shaped for each order based on the information provided in the Questionnaire. For more information, contact Steam Control Engineering, LLC (OOO)..
Dimensions and weight of standard configurations (approximate)*
* The actual unit may have slightly different appearance than the types shown in the figure below, but the stated dimensions will remain unchanged. For more information, contact Steam Control Engineering, LLC (OOO)..
Control system
The operation of the unit (HTG-PR-PN-.. or HTG-PR-EL-.. configuration) is controlled from the control panel of the modular heat transfer package, HTG series and includes the following functions:
- Steam pressure control.
- Signalling in case of pressure surge above the permissible value and failure to reach the setpoint within a specified time.
- Smooth start and shutdown.
Selection and installation details
The value of the mass flow rate of saturated steam Gs can be obtained based on the value of the rated heat transfer package power, using the heat balance formula. In this case, the steam enthalpy for typical models must be taken at a pressure of 2-2.5 barg.
