Vapor Curing I

Vapor Curing I

VAPOR curing for concrete block, brick aND cast stone

A direct-fired vapor generator in conjunction with temperature sensor(s) and motorized vapor control valve(s) accelerates concrete strength gain and increases concrete quality through the controlled addition of heat and humidity.

Functions

Vapor Curing I

  • Function 1

    Vapor Curing I

    When compared to a boiler, the direct-fired vapor generator reduces operating costs by 40% to 60%. The vapor generator requires minimal space and operates at low pressure with propane or natural gas.

  • Function 2

    Vapor Curing I

    AutoCure automatically measures and controls the curing environment. All curing data and operating status is displayed on a color display.

  • Function 3

    Vapor Curing I

    In conjunction with AutoCure, the stainless steel vapor control valve provides for full automatic control of the curing process. The design and the “fit-for-purpose” materials ensure a long life and simplified maintenance.

  • Function 4

    Vapor Curing I

    The vapor distribution system is designed using a pressure-drop algorithm and utilizes various diameter pipe and outlets in order to ensure even heat and humidity distribution. The insulated main distribution pipe outside the curing area reduces heat loss and provides a safe working environment.

  • Function 5

    Vapor Curing I

    The NAUTILUS™ radial air exhaust system evacuates the warm moist air from the curing chamber at the conclusion of the curing cycle. This exhaust cycle provides for a dry chamber and floor as well as for drier concrete products with stronger edges, corners and more uniform splits.

  • Function 6

    Vapor Curing I

    The NAUTILUS™ radial air circulation system provides for a consistent curing environment throughout the curing chamber. All NAUTILUS™ ventilators share a proprietary heavy-duty bearing, rotor and frame design for durability and simple maintenance.

  • Function 7

    Vapor Curing I

    Insulated curing chambers designed by KRAFT CURING with insulated steel clad sandwich panels and galvanized steel frames for long life durability are available for indoor or outdoor requirements. Upon request, stamped professional drawings are available to meet snow, wind or seismic load certification requirements.
