Grain cooler GCU,GCU-I

evaporative

The GCU (Green Cool Unit) is one of the Tolsma’s own innovations. Achieving optimal storage efficiency was the goal in developing this direct cooling system, so minimal drying-in and energy saving are crucial. GCU The application of advanced compressor technology in combination with an intelligent control system (developed in-house) has made it possible to achieve the highest possible efficiency for the total storage system. The GCU is available with a variety of cooling capacities ranging from 20 to 185 kW. Various other options geared to the special requirements of the product include electronic defrosting of expansion valves. The GCU can be supplied in a weather-proof casing or built into an engine room or container. GCU-I The GCU-I (Green Cool Unit-Indirect) is an indirect cooling system that we ourselves have developed. The GCU-I (chiller) was developed using the same criteria as those applied to the GCU units. This version is ideally suited to the storage of several types of product in different storage climates. The GCU-I provides the facility to cool separate cells at different temperature levels. The minimal temperature difference across the evaporator means that the storage efficiency of this cooling system is optimal, and the quantity of synthetic refrigerant required is minimal, so that less (statutory) maintenance is required. The GCU-I is available from 20 to 200 kW.
