The Convect-Air™ curing system, which uses Kraft Energy™ Systems technology, is designed for applications requiring accelerated curing/hardening of precast concrete products in insulated enclosures without the addition of moisture to increase relative humidity. Convect-Air uses a heavy-duty insulated air heater and high-performance radial ventilator to provide consistent temperature throughout the entire chamber.

Convect-Air Features

1. Reduced turnaround times. (Maintaining temperatures from 105°F to 140°F [40°C to 60°C] allows concrete products to be removed from the curing chamber in six to eight hours.)
   
   
2. 92-percent operation efficiency due to recirculation of heated air
   
   
3. Heavy-duty radial ventilator provides constant circulation preventing temperature stratification in the curing chamber
   
   
4. Stainless steel heat exchanger and modulating or single output burner for accurate temperature control
   
   
5. Multiple enclosures can operate at the same time
   
   
6. The user has a choice of burners – diesel, propane or natural gas
   
   
7. A timer allows for the user to automatically control the duration of the curing
   
   
8. An easy-to-use thermostat with a temperature sensor is located in the distribution manifold
