Recirculating chillers: K-series from ATC – cooling capacity: 4.500 – 14.000 W
They are active air/water recirculating chillers for accurate temperature control (+/- 0.1 °C), suitable for energy-intensive applications in laboratory and manufacturing processes.
ATC is the UK’s leading manufacturer of recirculating chillers and temperature control products. From standard products to fully customized systems, ATC can offer you the best cooling solution and temperature control for your problems.
What makes the device special:
- Robust design based on many years of experience at ATC with this type of unit.
- Accurate temperature control (+/- 0.1°C)
- K4 – K12 are also available as active water / water coolers. By connecting to your house water pipe, a power-saving and quieter application is possible.
Use for cooling / tempering of:
- Cosmetic production
- Semiconductor production
- Production of ophthalmic lenses
- Digital printing
- Laser lithography
- induction heating
- scientific applications (electron microscopes, ICP-MS, X-ray applications)
