Before being able to be used as biological fuel, biogas generated in dumps and digesters must be “purified”
by removing moisture and undesirable products that are easily condensable or filterable. Dehumidification is required in all processes where biogas is used, both to produce energy (in endothermic engines) and to produce biogas (biogas upgrading).
Green Box has been operating in this sector since 1997 with recognised product expertise and reliability and boasts of a range of several hundreds of biogas-chillers.
Green Box biogas chillers are derived from standard units that are designed and built for industrial use with “difficult” operating conditions and 24/7 operation throughout the year.
Therefore, they benefit from a generous sizing of components and a standardised construction process and subject to severe quality control.
Standard industrial chillers can cool biogas capacities ranging from 56 to 5,000 m3/h.
Standard equipment includes all protections that can ensure efficient and long-term operation.
Most biogas chillers are equipped with EC fans as an optional accessory, which also enables perfect operation with low ambient temperatures and considerable energy saving.
A simple electro-mechanical interface is a standard supply. More advanced electronic interfaces are available as an option.
Many production processes of chemical products
require thermal controls that can be simple cooling or heating at high temperatures, or thermo-dynamically controlled cycles (heating, maintenance and cooling with controlled temperatures and times).
Green Box industrial refrigerators can be applied directly to cooling of:
