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.

Projects
Vapor Curing I
Direct-fired vapor for concrete curing
Vapor is used in the precast concrete industry for the accelerated curing of precast products including concrete pipe, prestressed structural concrete, concrete block, ornamentel concrete, cast stone, and assorted precast concrete products.
New curing system for Western Materials, USA
For over sixty years, Western Materials has been dedicated to providing their customers with quality products including concrete architectural and hardscape products that they manufacture as well as other building materials. In 2005, due to rising fuel costs, Western Materials began exploring ways to more efficiently cure their concrete products.
Curing of concrete roofing tiles (Hungary)
Hungarian company Mediterran Kft. decided to upgrade the aftertreatment system of his main plant at Bóly in the heart of Hungary to a KRAFT Vapor Micro. Strong benefits over the old system which consisted of radiators and water spray injection, quality improvements, less breakage and a reduction in gas consumption justified the investment on short notice.
GCC moves to the technological forefront in the construction materials industry
When Grupo Cementos Chihuahua, GCC, of Mexico decided to build a new block, paver and architectural products production facility in Juarez, Mexico the decision was made to employ a KRAFT Energy accelerated concrete curing system in order to maximize production efficiency, while improving the characteristics of the finished product.
Bruk Bet relies on proven concrete curing quality on its anniversary
