RT

RT 280A and RT 281A are primarily used as liquid level alarms and safety switches to prevent too high a liquid level in liquid separators. Secondarily, RT 280A and RT 281A can be used as liquid level regulators where a liquid level differential of up to ±40 mm can be permitted. When used as safety switches, RT 280A and RT 281A ensure that the max. permissible refrigerant level in flooded evaporators, pump tanks or liquid separators is not exceeded. As liquid level regulators, RT 280A and RT 281A maintain a constant average refrigerant level in flooded evaporators, pump tanks or liquid separators.
