We offer special air cooled circulator for the Beer Force-Ageing-Test. It is equipped with a programmer for the change between 0 °C / 40 °C and 0 °C / 60 °C in a 24 hour cycle. Casings and bath parts are made of stainless steel.

Small, robust and cost effective with its stainless steel casing. The Minichiller is the smallest Unichiller in the world. Minichillers are available with air or water-cooled refrigeration systems, illuminated level indicator, overflow and drain on the front. The filling port is on the top of the unit. All models use natural refrigerants as standard. Minichillers have suction and pressure pumps and therefore have the advantage of have a high flow at low pressure. This is particularly interesting for all pressure sensitive applications (e.g. glass condensors).

High performance Unichiller with OLÉ controller for standard applications. The Unichiller with the OLÉ controller offers cooling powers up to 2.5 kW. The chiller is ideal for standard cooling applications in the laboratory or in industry. The energy efficient function of the chiller reduces the water consumption for many applications, helping to protect the environment and reducing operating costs. All models are fitted with the OLÉ controller with its modern OLED display as well as for RS232, USB interfaces and PT100 measurement sensor connection.

P-models include circulating pumps with a high discharge pressure for applications with high pressure drops.

The Huber circulators are split into two product lines, the Compatible Control models and the simpler KISS models. Both model lines represent classically constructed laboratory circulators with open baths. Baths and circulators for heating applications up to +300°C are available, as well as models for heating and cooling applications from -90°C to +200°C. Immersion or bridge circulators are suitable for thermal control of existing baths. The Ministat, the smallest cooling and heating circulator in the world, is the first choice for operation in fume-hoods or integrating into systems.

Circulators with Pilot ONE Controller
Models with Pilot ONE Controller convincing in practice with their highly precise temperature control and a professional range of functions even in the basic version. The electronic upgrade function "E-grade" allows a simple and low cost expansion of functions at any time. Operation is simple using large colour displays, an easily understandable menu and an individually customisable display. Models with the Pilot ONE have powerful pressure and suction pumps with continuously variable speed control for adjusting circulation to the bath in use. Further connections are available via the optional Com.G@te, e.g. RS232 and RS485, analogue interface 4 to 20mA or 0 to 10V, standby signal and programmable alarm.

Circulators using the KISS Controller
The functions of models with the low price KISS controller concentrate on the essentials.

Many applications depend on a reliable source of cooling. Circulating chillers in the Unichiller range offer an ideal solution for environmentally friendly and economical cooling in laboratory and industry. There are over 50 air and water cooled models to choose from, with cooling powers from 0.3 to 50 kW. Efficient energy management in all Huber chillers ensures low operating costs and reduced usage of valuable fresh water. Huber circulating chillers are a resource saving solution with a quick return on investment.
Options on request: heating, natural refrigerant, externally open applications, winter option, outdoor setup.

Heat exchanger systems with circulation pump for connection to cooling water on the primary side. The devices provide a cooling circuit with stable pressure/ ow and adjustable operating temperature. The cooling capacity is generated using a plate heat exchanger via the cooling water. Since there is no active cooling machine, the devices operate in a quiet and energy-saving manner and are a cost-effective alternative to conventional chillers e.g. for the temperature control of Peltier elements, bioreactors, etc.

The model HTS 1 contains the heat exchanger system, however it does not have any temperature control. The device is therefore suited for applications with low requirements for control accuracy.
