La maggior parte delle applicazioni dipende dall'affidabilità della sorgente di raffreddamento. I refrigeratori a circolazione della gamma Unichiller® rappresentano la soluzione ideale per il raffreddamento economico e a basso impatto ambientale per il laboratorio e l'industria. La gamma comprende oltre 50 modelli con raffreddamento ad aria e acqua tra cui scegliere, con potenze di raffreddamento da 0,3 a 50 kW. La gestione efficiente dell'energia garantisce bassi costi operativi e uso ridotto di risorse preziose come l'acqua dolce. I refrigeratori a circolazione Huber sono una soluzione vantaggiosa in termini di risparmio delle risorse e offrono un ritorno rapido sull'investimento.

A calculation of water and wastewater costs shows that a Minichiller can save up to 48000 litres of water in a working week and due to its low purchase price, return on investment is achieved within a very short time. The units have small footprints, only requiring 225×360 mm on the laboratory bench and are therefore suitable for cooling reactor blocks, vacuum pumps, rotary evaporators or heat exchangers. Minichillers allow stable application conditions due to constant values for temperature, pressure and throughflow quantities. They are also perfect for continuous operation at ambient temperatures up to 40 °C. Despite their economical purchase price the coolers are well equipped and have a large temperature indicator, fill level indicator, as well as status LEDs for the pump, cooling and heating. A 1 kW heater is optionally available with which the temperature range can be extended to 100 °C. Minichillers are available as both air and water cooled models and use natural refrigerants.

Chillers also reduce water consumption and help conserve the environment whilst lowering operating costs. Unichillers are suitable for the removal of heat from chemical processes, cooling technical plants or as a central cooling water supply for laboratories. All Unichillers are designed for continual operation at ambient temperatures up to +40 °C. Installation in an outside areas is possible with optional weather protection and winter operation packages. Pumps are available with an extended pressure and flow rate for applications with high pressure drops.

The Pilot ONE® controller is interchangeable and can be used as a remote control (with an optional data cable).
Pilot ONE® controller offers a brilliant 5,7" touchscreen with graphic functions and a comfortable navigation menu in 11 languages (German, English, French, Italian, Spanish, Portuguese, Czech, Polish, Russian, Chinese and Japanese) and USB and Ethernet connections. User can set visual and acoustic alarms, limiting the temperature range, and program the unit with its clock and calendar functions for auto start for unsupervised startup. Powerful pressure pump, bench models with max. pump pressure of 3 bar have a built-in, adjustable bypass and a pressure gauge; in floor-standing models pressure control is carried out via external bypass (optional).

Unichillers® with MPC controller are compact, value for money units; Unichillers® are available with cooling powers up to 2,5 kW for applications in the laboratory. The models ranging from the Minichiller® to Unichiller® 025w-MPC are suitable for use on or under the laboratory bench. The MPC Controller is robust, ideal for simple applications and easy to use controller with three keys and LED display.

Unichillers with Pilot ONE®: The tower models offer power with small footprints. These models are fitted with the new exchangeable Pilot ONE® and are used in both research and production.

Suction pump max. : 10,5 L/min; 170 mbar (Minichiller 300 and 280) and 18 L/min; 400 mbar (Minichiller 600).
