The Labo B series circulators have cooling and heating features. When the cooling feature is turned off by a switch, the circulators can be used as a heating circulator. Thus, energy conservation is provided. The Labo B (Big) series circulators offer bath capacity alternatives between 20 and 54 liters and work with environmentally friendly refrigerants (NON CFC) that do not damage the ozone layer.
