Mini - 500W Recirculating Chiller

The Mini series:

The M-series range of chillers are the smallest and most advanced units produced by ATC. With a small footprint (similar to a desktop PC), and variable speed fan and compressor the Mini is ideal for the laboratory, where noise and space are concerns.

Designed to replace the popular KT series, the Mini combines excellent cooling performance with a 24VDC internal circuit. This means that the M-series of chillers is both incredibly energy efficient, and suitable for any power supply (90-240V, 50/60Hz)

Not limited to the laboratory, the robust steel enclosure means that the Mini are also suitable for industrial applications, like cooling lasers.

Using a sophisticated touch screen controller the Mini is capable of maintaining temperature stability of less than +/-0.1^oC.

The ecoMini provides precise and adjustable cooling power, but without set point control. This makes them a very cost effective, but reliable solution.

Applications: Bioreactors, Electron microscopes, Lasers, Automation systems, Vacuum pumps, Rotary evaporators, Electrophoresis, water baths,

The ecoMini :

The ecoMini has been designed to supersede the successful KTR range of chillers. Originally designed for cooling turbo pumps, the ecoMini and KTR chillers are ideal where excess heat has to be removed efficiently and quietly.

The ecoMini lacks a PID controller, but has an adjustable rate of cooling so that you can achieve your required temperature. An LCD display shows the temperature the chiller is achieving.
