- CurePak direct-fired steam generators for concrete curing (advanced and basic models)
- Kiln control systems
- Air circulation and exhaust systems
- Installation and turnkey services
- Misting and dry burners
- Drying systems
- Piping and equipment installation

CurePak Is Now Part of the Afinitas SmartSet Curing Offering
Direct-Fired Curing Systems
Reliable and robust direct-fired steam generators are capable of producing large volumes of controllable, low-cost steam – instantly. Operating at half the cost of traditional boilers, Return On Investment (ROI) can be achieved in two years or less, adding profits to your bottom line.
Benefits of Steam Generation:
Reduced Operating Costs – uses half the gas and water required for boilers
Increased Production – produces instant steam for nearly 100% thermal efficiency
Reliable Performance – operates efficiently and dependably
Worker Safety – combustion occurs before water can contact hot air, minimizing the risk of carbon monoxide production
Flexible Curing Parameters – ideal for jobs requiring both intermittent and continuous steam production
Available in a high pressure version, up to a maximum of 10 PSI at 3 MMBTUH
Operators or automatic controls are continuously changing which valves are open and shut to curing areas to meet production requirements. This changes the load needed for the curing system. SmartSet™ adjusts the firing rate for the curing load automatically to cure your product efficiently and maintain proper temperature control. It automatically adjusts the burner to compensate for upstream changes in water pressure changes.
Automated Temperature Control
The accurate control of SmartSet’s outlet temperature is critical to curing a wide variety of concrete products. A very small change in the water flow results in a large change in outlet temperature. Our system automatically anticipates thermocouple reaction time during outlet temperature changes. SmartSet™ also automatically compensates for any changes in upstream water pressures or water delivery.
• Ensures accurate viable control over the quality of the cure steam
• Avoids head losses caused by excess water common in low output-temperature curing systems
The heart of the combustion system is the precision burner assembly. The burner is engineered to provide positive flame propagation and flame retention under a wide variety of gas/air ratios and line pressures. Because of this, SmartSet™ starts and burns consistently under varying operating pressures.
Large Combustion Chamber
The chamber provides the three “T’s” of proper combustion:
TIME, TEMPERATURE and TURBULENCE:
• Large enough to provide the TIME to ensure completion of combustion prior to the introduction of water.
• Lined with refractory, this assures flame TEMPERATURE for proper combustion.
• Produces the desired TURBULENCE for a clean burn.
Auto Fog Control Panel System
This kiln control panel is designed to “steam” and “hold” a kiln to a selected target temperature, or to intermittently “fog” a kiln. It also has the logic for intermittent control of a misting system. It can do any of these three functions during each “PRE-SET” or “CURE” cycle. A dual setpoint temperature controller displays and controls the kiln temperature during each cycle if the “steam” option is selected.
If “FOG” or “MIST” is selected, the on and delay times are programmable to achieve a desired kiln humidity for weekend or “hot summer day” curing.
Our revolutionary circulation system creates even circulation of heat and moisture throughout the kiln which ensures that every pipe is properly cured to achieve optimal strength.
The accurate control of the CurePak’s outlet temperature is critical to curing a wide variety of concrete products. A very small change in the water flow results in a large change in outlet temperature. Our control system automatically anticipates thermocouple reaction time during outlet temperature changes. The system also automatically compensates for any changes in upstream water pressures or water delivery.
This exclusive outlet temperature control system assures accurate variable control over the quality of the cure steam and avoids the heat losses caused by excess water common in low-output-temperature curing systems.
Drying for Block Systems
When your customer requires product that is classified as dry block, our drying system is the solution you need. The depth of dryness is determined by the amount of time the block is dried. As a component of our overall curing system, this versatile dryer can achieve optimal surface dryness without re-handling the block to move it into a separate drying system.
Alternatively, our dryer can be used as a standalone system. It is ideal for producing block that is going to be treated with an epoxy coating, ensuring a perfectly dry surface for optimal bonding properties.
Our misting system ensures that your product stays moist before curing. We offer multiple types of misters, based on how much automation and ease of maintenance your process requires.
A Series Burner System
This unique curing system is comprised of a wide variety of solutions that can be customized for any concrete product. We start with our proven burner and add the components that best fit your product and curing requirements.
For example, our equipment for block production is designed with our A-series burner, an A-series vaporizer, fog control system, circulation system and misting system. It can also be equipped with an exhaust system to eliminate moisture from the kiln before it is opened, to prevent it from being released into your plant.
Our A Series System can also be equipped with a fog kiln control panel. During summer or in a desert climate when a reduced amount of energy is needed for curing, you still need the right amount of moisture during the precast step to avoid spider cracks that can occur when the pipe gets too dry. The fog kiln control panel allows you to easily adjust time and temperature parameters to ensure the highest product strength possible.
Canopy Kiln Curing System
The traditional solution to the curing of concrete pipe, manhole and box culverts is the Canopy Kiln System. Utilized in hundreds of factories, the Canopy Kiln System is economical, functional and extremely flexible in that it can be adapted to any type of building or arrangement. Manually operated, the Canopy Kiln is simple to use and even simpler to maintain, with minimal moving and wearing parts. The Canopy Kiln System folds up against the kiln wall throughout the production process, and when the kilns are full, the overhead crane is used to deploy the curtains and cover the concrete pipes, at which point steam may or may not be introduced into the system, depending on the wishes of the producer or the local climate. Look to HawkeyePedershaab and BFS Canopy Kiln Curing Systems for equipment that is:
- Simple to operate
- Simple to maintain
- Adaptable to any plant layout
Telekiln Curing Systems
The TeleKiln is an accordion-style curtain kiln system that advances over the concrete products in the kiln as they are produced, covering them and keeping the wind and external environment from affecting the curing process. This system is especially popular in warm, windy climates where the ambient temperature necessitates the opening of plant doors, allowing winds to blow across the products in the kilns, drying them out and preventing proper curing. Telekiln can be remote-controlled and includes an optional misting system to keep the concrete products properly hydrated. The system also has the added benefit of operating without tying up the plant’s overhead crane. HawkeyePedershaab and BFS Telekiln curing systems are know for:
- Immediately covering the pipe
- Automatic misting system
- Remote-controlled operation
- Adaptability to any plant layout
Autokiln Curing Systems
The AutoKiln Curing System represents the most advanced concrete pipe and manhole curing system in the marketplace. Tailored to work in conjunction with a moving-floor automatic factory, AutoKiln allows for precise, zoned, computer-controlled manipulation of the temperature and humidity throughout the entire curing process, including pre-cure and post-cure processes. In addition to its ability to fully control the curing process, AutoKiln uses high R-Value, insulated walls and doors to reduce energy usage and prevent corrosive steam or humidity from leaking out of the system and affecting the rest of the factory. Trust HawkeyePedershaab and BFS Autokiln Curing solutions for:
- Allowing 24-hour continuous production
- Complete control of the curing process
- Independent temperature and humidity control
- Fully automatic operation
