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 many outputs and heating specifications and burn natural gas or propane.

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.
In April 2013, Sovereign Concrete of Australia contacted KRAFT CURING SYSTEMS to replace an outdated boiler system. In compliance with local standards and Sovereign’s unique specifications, Kraft designed a complete energy-efficient curing system for Sovereign’s two production buildings.
