DYNEO DD-1200FW Refrigerated / heating circulator new

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.

Despite its very compact design, the water-cooled Refrigerated / heating circulator DYNEO DD-1200FW, which has a working temperature range of -50 ... +200 °C, delivers a powerful cooling capacity of kW at 20°C. Water-cooled systems are normally more efficient than air-cooled systems, as water has a higher specific heat capacity than air. In addition, they introduce far less waste heat into the environment, which helps create a pleasant working climate.

This cooling machine works with natural, environmentally-friendly refrigerant and was developed with a focus on energy efficiency. This means significant savings up to 70% on the operating costs for numerous applications, which also means rapid amortization of the procurement cost. At the same time, the lower energy consumption positively contributes to climate protection.

Optional analog and digital interface

DYNEO circulators can optionally be equipped with analogue or digital interfaces. To request the options, order number must be extended with .d for the digital and .a for the analog interface (9XXX XXXX.A / 9XXX XXX.D)
