Vapor Curing III

Vapor Curing III

VAPOR curing for prestress and precast concrete products

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. Vapor generators are available in several outputs and heating specifications and burn both natural gas and propane.

Functions

Vapor Curing III

  • Function 1

    Vapor Curing III

    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 III

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

  • Function 3

    Vapor Curing III

    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 III

    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 III

    A wireless temperature measurement and data logging system is available as an option. This secure wireless environment is designed especially for use in precast and prestress production areas with multiple signal repeaters that allow for a greater coverage area.

Projects

Vapor Curing III

Project

Remote overnight concrete curing for bridge elements

For the densely populated state of New York the Tappan Zee Bridge, crossing the Hudson river north of the city of New York constitutes a vital artery for residents, commuters, travellers and commercial traffic. The bridge opened to traffic in 1955 and was at that time designed for a humongous number of 100.00 vehicles per day.
