Cooling and heating thermostats, stainless steel, with natural refrigerant, Ministats
Supplier: HUBER
Their compact dimensions enable Ministats® to be placed in the smallest of spaces, for example in a laboratory fume cupboard or inside technical plant. Despite their minimal size the systems have a wide variety of features and offer performance levels suitable for temperature control of photometers, refractometers, viscometers, distillation apparatus, reaction vessels and mini-plants. They are mainly used for external applications, however the bath opening allows objects to be thermoregulated directly in a thermostat bath. A powerful pressure/suction pump with an infinitely controlled rotational speed ensures optimum circulation. The maximum pressure can also be regulated by an optional pressure sensor, meaning that sensitive glass reactors and apparatus can be protected from breakage. Ministats® have the 'professional' level Pilot ONE® controller as standard with a colour TFT display and convenient operator guidance. Analogue NAMUR connections are available via the optional Com.G@te module allowing Ministats® to be integrated into plant and process control systems. The Pilot ONE® multi-touch controller features a brilliant 14,5 cm touchscreen with graphic functions and easy navigation menu in 11 languages. All important operating parameters and temperature values are clearly displayed on the touchscreen. The favourites menu, one-click operation and the integral technical glossary mean operation is simple.
