New temperature control technology for demanding applications
Refrigerated circulators of the DYNEO series distinguish themselves with a great price-performance ratio. The instruments offer high heating/cooling capacities for short heat-up and cool-down times. The refrigerated circulators work precisely and reliably even at higher ambient temperatures up to +40 °C. Either in basic research, in material testing or in technical systems – the DYNEO refrigerated circulators offer functional solutions for every requirement and budget.
The DYNEO DD-449F refrigerated circulator has an exceptionally large bath volume. This makes the unit ideal for precisely tempering larger or a variety of different samples in the bath.
The 449F cooling machine uses natural, environmentally friendly refrigerant and was also developed with a focus on energy efficiency. This leads to significant operating cost savings in many application scenarios and thus to a faster amortization of the investment. At the same time, the lower energy consumption makes a positive contribution to climate protection.
