THE PERFECT CLIMATE AND PERFORMANCE IN A SINGLE ATMOSPHERE CHAMBER
QUADRIX® accelerates the curing process through the controlled addition of heat and humidity. This guarantees a continually uniform environment for curing. The system allows high air volumes at a low flow rate. The result is an improved, smooth surface.
The rack is enclosed with insulated sandwich panels in order to reduce heat loss. Drawings and Bills of Materials supplied by KRAFT allow our clients a foolproof do-it-yourself solution for chamber insulation.
The Quadrix® system prevents fog and condensation on chamber surfaces even at 35 °C (100 °F) and 90 % relative humidity. This prevents disruption of safety beams or control lasers and corrosion of the steelwork.
Our Quadrix® unit is manufactured of stainless steel, aluminum and galvanized materials. Dual high performance radial ventilators provide high volume air circulation, while the 94% efficient heat exchanger is designed for efficiency and durability.
Our AutoFog® misting system humidifies the air with finely sized atomized water particles in order to increase the relative humidity. The water is filtered, softened and disinfected via ultraviolet light.
Our custom designed air distribution duct system with 100s of air supply outlets and air return inlets guarantees a consistent curing climate throughout the curing chamber while ensuring low air velocity.
Our AutoCure® curing control system with 9” color touch screen allows for independent measurement, indication, control, real-time graphing and, optionally, data logging of curing temperature and humidity. Curing Temperature and relative humidity are measured via sensors distributed throughout the chamber.
Our custom designed exhaust system with electrically actuated damper (in order to prevent heat loss when not in operation) operates in order to reduce humidity.
Custom designed chamber entry and exit exhaust hoods prevent warm moist air from escaping into the production area. The hoods are heated in order to prevent condensation from forming and dripping onto the fresh concrete products.
consistent curing temperature equal to +/- 1 °C
and relative humidity equal to +/- 3 %
with an air velocity ≤ 1 m/s
curing climate controllable per production requirements
significantly reduced hardening duration, less breakage
consistent colors, a substantially reduced risk of efflorescence
no condensation on chamber surfaces
approximate 10% cement reduction with less racks and production pallets
Suitable for all curing systems, insulated chambers reduce energy costs by 50% and prevent condensation.
Curing racks for the storage of concrete products during the hardening and curing process.
Fully automatic system thaws and heats frozen aggregates for winter operation.
Measures and controls the curing temperature and relative humidity for a fully-automated and repeatable curing process.
The economical air circulation solution utilizes the heat from cement hydration and moisture from the concrete.
KRAFT CURING offers reliable quality of equipment to impove concret quality while saving money.
Controlled addition of heat, humidity and carbon-dioxide for the accelerated curing of concrete block, block paving and cast stone products in insulated enclosures.
Paving Stone Production At Its Best“32 °C and 98% rH and everything remains dry!”The four components of the QUADRIX® accelerated concrete curing system – the optimal curing chamber insulation, low velocity air circulation, control of curing temperature and relative humidity eliminates issues with condensation and guarantees a constantly consistent high early strength.
Benefits of the inovative QUADRIX® Curing Technology
For producers of concrete pavers and blocks, switching to a Single Atmsophere Curing Chamber (Big Room) offer substantial benefits. A factual, indepth and informative dissertation, written for the Dublin Institute of Technology, provides the hard facts.
