KTI - SAUTER CombiMaster (CM)

The KTI - SAUTER CombiMaster is used when the fresh concrete has to be heated in winter before processing and cooled in summer.

The CombiMaster contains a fully-fledged heating system and refrigeration system in one unit. This ensures the provision of feed water, which is cooled in summer and heated in winter. Likewise, cold air is generated in parallel in summer and hot air in winter for silo cooling or heating.

The CombiMaster is the only solution on the market that offers such versatile and flexible use.

Plant information

KTI - SAUTER CombiMaster contains a complete refrigeration system for active cooling of water and air. Likewise this contains two heating units for heating water and air.

Heating and cooling, however, share the periphery. This has the unbeatable advantage that only one water pipe and one air pipe must be laid from the CombiMaster to the concrete batching plant. In addition, the CombiMaster is very compact, as the plants share one machine room.

Winter operation

In the winter, a KTI - SAUTER hot water system (HWS) heats the fresh water up to +85°C. A KTI - SAUTER hot air system (OLH) is responsible for heating the cold ambient air in order to heat the silos with the hot air. Both systems can be operated independently of each other, which is particularly useful in the transitional period. enormous savings brings with it.

Summer operation

In summer, a glycol chiller installed on the roof provides the required cooling capacity. The cold glycol is pumped through both a plate heat exchanger and an air register.

In the plate heat exchanger Fresh water cooledwhich is then buffered in the boiler of the hot water system.

In the air register, the ambient air is cooled before it flows into the silos. So, unlike other products, the CombiMaster actually provides Cold air and not only ambient air is available for rock cooling.

Summer operation of the CombiMaster: Air is actively cooled via a refrigeration system before it flows through the aggregate silos. Cold water is produced at the same time, which is used as feed water.

Winter operation of the CombIMaster: Air is heated to 130-150 °C in the OLH air heater and then flows through the sand and gravel silos. Required water is heated to 40-60 °C with 300 kW heating power.
