SIGMA water-condensed water chillers are designed to produce cold water for plant cooling. They are integrated cooling units, totally independent, made of a complete hydraulic circuit with a closed storage reservoir, a circulator and an electric pump.
Besides the production of cold water, SIGMA chillers can produce process hot water (max 90° C) intended for temperature control of industrial processes.
According to the version you select, machines can be at 1 cooling circuit (OC/1 version), or at 2 heating/cooling circuits (HH version).
The machines are equipped with evaporator and condenser plates which, due to their over-size, allow the compressor to function at maximum efficiency. All chillers deliver high efficiency and very low power consumption even in extreme conditions.
The low noise of these machines allows installation in production departments.
