Projektübersicht
In November 2025, we successfully delivered and commissioned an HZS90C containerized concrete batching plant for an infrastructure contractor in Calgary, Alberta. Facing the looming freezing winter, the client required a highly insulated, fast-deploying solution to supply concrete for a regional commercial and transportation hub. Operating at a steady 90 m³/h, this winter-ready plant ensures continuous, high-quality concrete production even when temperatures drop to -30°C.

Canada’s infrastructure sector is booming, particularly in Alberta’s energy and commercial corridors. However, operating in this region means battling one of the most unforgiving climates on the planet. For contractors searching for a reliable concrete plant Canada, the true test of equipment isn’t just its output capacity, but its ability to survive and thrive in extreme freezing temperatures. This case study details how our HZS90C containerized batching plant was engineered to defeat the Canadian winter, providing uninterrupted concrete supply for a major infrastructure project in Calgary.
Client Requirements & Procurement Criteria
When the Alberta contractor approached us, they were not just looking for a standard batching plant; they needed a highly specialized system tailored for their specific operational and environmental constraints. During the procurement phase, the client strictly defined the following criteria:
Uninterrupted Cold-Weather Operation
The plant must maintain full production capacity at -30°C without requiring manual defrosting of pipes or scales.
Rapid Mobilization
Due to the looming winter, the entire system had to be installed, commissioned, and producing concrete within a 14-day window to avoid pouring deep foundations into frozen ground.
High-Precision Air-Entrainment
To meet strict CSA (Canadian Standards Association) standards for freeze-thaw resistance, the weighing system must guarantee ±1% accuracy for water and chemical admixtures.
Ease of Operation for Local Crews
The control system needed to be intuitive and fully automated, minimizing the need for operators to work outside in dangerous, freezing conditions.
Low Maintenance Accessibility
Critical maintenance points (lubrication, filters, pneumatic valves) had to be easily accessible from inside the insulated cabin, allowing servicing without exposing technicians to the extreme cold.
Project Challenges: Alberta’s Extreme Winter
The stringent requirements set by the client were a direct response to the brutal realities of pouring concrete in Western Canada:
- Extreme Cold and Freeze-Thaw Cycles: Calgary routinely experiences temperatures plunging to -30°C during winter. In such conditions, water lines and admixture pipes freeze solid in minutes, and aggregates can clump together with ice. Furthermore, standard steel components become brittle, and pneumatic valves fail to operate in the extreme cold.
- Extremely Short Construction Windows: The effective building season in Alberta is brief. Traditional stationary plants require weeks of heavy civil work and concrete curing, which can easily push a project past the summer window, forcing contractors to halt operations until spring.
- Deep Frost Line Foundations: The ground freeze depth in Calgary can exceed 1.5 meters. Pouring a massive, heavy concrete foundation for a traditional plant during late autumn is astronomically expensive and structurally risky due to frost heave.
- Rigorous Quality Standards for Freeze-Resistant Concrete: Canadian standards demand highly precise air-entrainment and slump control in concrete to resist freeze-thaw damage over decades. Any deviation in the batching process can lead to catastrophic structural failures later.

The Solution: Why Choose the HZS90C Containerized Batching Plant?
To overcome these freezing challenges and meet every criterion of the client, the HZS90C containerized batching plant was the only logical choice, customized specifically for the Canadian climate:
- Comprehensive Winterization & Insulation: The containerized structure is inherently easier to insulate. We lined the entire mixing tower and control room with 100mm high-density rock wool. Industrial 15kW duct heaters were installed inside the mixing cabin, maintaining an internal temperature of +10°C even when it’s -30°C outside. This ensures water lines, admixture pumps, and scales remain completely ice-free, satisfying the requirement for uninterrupted operation.
- Rapid Deployment on Frost-Susceptible Soil: Because the HZS90C is a self-contained modular unit, it transfers the structural load across a wide footprint. Instead of excavating below the 1.5m frost line, the plant was placed on a simple, reinforced concrete slab-on-grade, saving the client weeks of foundation work and allowing for the requested 14-day fast-track installation.
- Cold-Weather Pneumatics and Electronics: We upgraded the air compressor system with a refrigerated air dryer and auto-drain valves to prevent condensation from freezing in the airlines. All pneumatic cylinders were specified with arctic-grade seals to prevent sticking, ensuring low-maintenance access inside the cabin.
Key Specifications and Performance Highlights
Beyond just surviving the cold, the HZS90C delivers the precise mixing performance required to meet the client’s high standards:
Reliable 90m³/h Output
Powered by the JS1500 twin-shaft mixer, the plant delivers a consistent 90m³/h. The forced mixing action is crucial in cold weather, ensuring that ice-chilled aggregates and heated water are blended quickly and thoroughly before the concrete loses its workability.
Precision Air-Entrainment Control
To meet the client’s strict CSA requirements for freeze-thaw resistance, the batching plant features high-accuracy load cells. The ±1% accuracy for water and admixtures ensures the exact dosage of air-entraining agents, preventing structural spalling in the future.
4.1m Discharge Height for Snow-Ready Trucks
The 4.1m discharge height is specifically designed to accommodate commercial mixer trucks fitted with tall snow tires and chains during the winter months, ensuring safe and spill-free loading under any conditions.

Project Execution and Site Delivery
The modules arrived in Calgary in late October, just as the first snowfall was hitting the ground. Because of the containerized design, the local crew did not need to spend weeks assembling steel frameworks in the freezing wind. The containers were simply lifted into place, and the pre-installed cables and pipes were connected. Within just 12 days, the plant was fully erected and calibrated—well within the client’s 14-day mobilization requirement.
During the wet-test commissioning in mid-November, an Arctic cold front caused ambient temperatures to drop to -25°C, presenting a rigorous operational test. Despite the extreme external conditions, the plant’s thermal systems performed as engineered. The internal heating units maintained the cabin environment at +10°C, ensuring all water lines, admixture pumps, and weighing sensors remained fully operational without freezing. Heated water at 60°C was integrated into the mixing cycle, and the enclosed aggregate bins prevented material from clumping. Under automated control, the JS1500 mixer operated continuously, successfully discharging the first batch of temperature-controlled, air-entrained concrete that met all CSA specifications.

Client Feedback and Project Impact
Months later, through the depths of the Alberta winter, the plant has run flawlessly. The client was thrilled with the decision to choose a containerized model over a traditional open plant. As the project director shared:
“Installing a traditional plant here would have meant pouring massive foundations in the summer and still risking frozen pipes by November. The HZS90C went up in 12 days on a simple pad. The insulation is incredible—we’ve had zero downtime due to frozen lines, and the air-entrainment accuracy is keeping us strictly within CSA standards. This plant is a winter warrior.”
