Ice Making Machine for Construction & Concrete Cooling
From concrete temperature control to tunnel and mine cooling, Koller provides block ice, flake ice and tube ice solutions that bring down mixing temperatures fast — preventing thermal cracking and ensuring structural integrity in hot-weather construction.
From concrete batching plants to tunnel boring and deep mine ventilation, Koller covers the full cooling chain for construction — block ice machines, flake ice machines, tube ice machines, ice crushers, blast freezers and walk-in cold rooms, all engineered around your project scale and ambient conditions.
Where Koller Ice Machines Work in Construction
Concrete Cooling
Flake and block ice lower concrete mixing temperature to control hydration heat, preventing thermal cracking in mass pours for foundations, bridges and high-rises.
Tunnel Construction
Block ice and flake ice systems cool tunnel boring environments and ventilation air, protecting workers and equipment in deep underground projects.
Mine Cooling
Large ice blocks transported underground absorb heat from airflow in ventilation shafts, lowering ambient temperature in deep mine tunnels where conventional AC fails.
Dam Construction
Mass concrete pours in dam projects require precise temperature control. Koller block ice machines deliver the high-volume, slow-melt cooling needed for structural integrity.
Block Ice vs Flake Ice for Construction Cooling
Both block ice and flake ice play critical roles in construction — the right choice depends on your cooling duration, mixing method and project scale.
Block Ice Machines
Long-lasting & high-density cooling- Large, dense ice blocks that melt slowly — ideal for pre-cooling aggregate and mixing water before concrete batching.
- Perfect for dam construction, mine cooling and large-scale infrastructure projects where sustained cooling is needed.
- Available from 1 to 200+ tons per day, with containerized options for remote sites.
Flake Ice Machines
Fast mixing & uniform cooling- Thin, flat ice flakes that mix directly into concrete batches for rapid, uniform temperature reduction.
- Ideal for precision temperature control in hot-weather concreting, tunnel cooling and smaller construction projects.
- Ice is ready in under 2 minutes, available from 0.5 to 100+ tons per day.

Tube Ice
Hollow cylindrical ice that is dense, food-grade and melts slower than flake ice. Used in construction site worker cooling stations and concrete pre-cooling.

Construction Ice Cooling FAQ
What type of ice is best for concrete cooling?
Flake ice and block ice are the two most widely used types for concrete cooling. Flake ice mixes directly into the concrete batch for rapid, uniform temperature reduction. Block ice is crushed on-site and added to the mixing water or aggregate, providing longer-lasting cooling for large pours in extreme heat.
How does ice cooling improve concrete quality?
Adding ice to concrete lowers the mixing temperature, which controls the hydration heat during curing. This prevents thermal cracking, improves structural strength and extends working time in hot weather — critical for dams, tunnels and large foundations.
What capacity ice machine do I need for a construction project?
Capacity depends on daily concrete volume, ambient temperature and target mixing temperature. Koller offers block ice machines from 1 ton to 200+ tons per day and flake ice machines from 0.5 to 100+ tons per day. Share your project details and our engineers will size the right system.
Can ice machines be installed at remote construction sites?
Yes. Koller provides containerized ice making systems that can be transported and installed at remote sites including tunnels, mines and dam projects. These units are self-contained with integrated cooling, water supply and electrical systems.
What is the difference between block ice and flake ice for construction?
Block ice produces large, dense blocks that melt slowly and are ideal for pre-cooling aggregate or mixing water before concrete batching. Flake ice is thin and flat, mixing directly into concrete for faster and more uniform cooling. Block ice suits large-scale projects; flake ice suits precision temperature control.
How does mine cooling with ice blocks work?
Large ice blocks are transported underground and placed in ventilation shafts or cooling chambers. As the blocks melt slowly, they absorb heat from the airflow, lowering the ambient temperature in deep mine tunnels. Koller block ice machines from 5 to 200 tons per day support mine cooling projects worldwide.
What temperature does a blast freezer for construction materials reach?
Koller blast freezers reach freezing temperatures of -60°C to -25°C, with fast cooling speed and an adjustable temperature system. Walk-in freezers hold -25°C to -12°C and walk-in coolers hold -12°C to +5°C.
What warranty do Koller machines carry?
All machines carry a 1-year warranty covering free repairment and components. Beyond the warranty period, the same service is still provided at cost.
