Snowkey Water Cooling  Concrete Systems Features:

    During condensation and rigidification process of concrete, hydrated cement produces a large amount of hydration heat. When the heat accumulates, the temperature increase inside the concrete will become rapider. The concrete structure is thick and large, which has low thermal conductivity and makes the heat hard to emit, therefore, the temperature difference between the inside and the outside of the concrete is excessive and tensile stress comes up. When the tensile stress excesses the current concrete ultimate tensile strength, the concrete surface will crack. Generally, the temperature difference between inner and outer part of the concrete should not exceed 25, otherwise, there would be temperature crack to the concrete will came into the crack.

 

    In order to prevent cracking, maximum temperature inside the concrete should be controlled strictly. One of the methods of controlling temperature is to reduce the concrete pouring temperature. Therefore, the concrete-out temperature should be limited. In hot season, the concrete-out temperature, in natural conditions, sometimes excesses the temperature limited by construction. Then, artificial temperature reduction is needed. Namely, pre-cooling the aggregate and mixing the concrete with cold water and flake ice to reduce the concrete-out temperature. This is the most effective measure for reducing concrete pouring temperature.

   Snowkey focuses on research, manufacturer and sales of the concrete cooling equipment. We have provided overall cooling and temperature reducing system for many famous skyscrapers, water conservancy projects, nuclear power projects, mines and so on. Our products mainly include ice-making system, water-chilling system and automatic flake ice storing and delivering system. Snowkey passed the certification of ISO 9000 quality system, ISO 14001environment management system and CE.

General characters of water chiller

 

    Snowkey water chilling system is containerized, which makes it convenient to move and suitable for work site with atrocious working conditions. It is specialized in cooling down water for the batching plant from 46to 0.5 (the water-in temperature can be higher, according to clients actual situation). Evaporative condenser and 4-stage water cooling system.

 

Snowkey water chiller has high efficiency. It adopts 3 or 4-stage cooling system. Evaporative condenser is hot galvanized. The plate exchanger is equipped with gauges and operation panel. At least 2 sets of compressor in parallel connection are equipped, which consumes less energy (more than 25%) than usual water chiller. Each set of water chiller is also equipped with one set of cold water circulation pump, which can cool down the water temperature from 45-50 to 0-0.5 in atrocious conditions. Highly effective plate heat exchanger is opted, which is energy saving, useful for controlling working conditions, has small volume and small size, etc. It is reliable, especially the 3rd stage plate heat exchanger. It can produce 0.5 cold water without freezing, which can avoid ice jam danger.

 

    The refrigeration system can adjust the compressor load and unload automatically according to the water temperature (suction pressure) to ensure constant cold water out temperature. Consequently, compared with other manufacturers water chiller, Snowkey water chilling equipment is better in energy saving and lower in operation cost.
