LAUDA ECO Heating and Cooling Thermostats

Economical thermostating in the laboratory from -50 up to 200 °C

The new ECO is a continuation of the amazing success story of the current LAUDA Ecoline. There are innovations and developments particularly with regard to the range of features and the ease of operation. Both control heads, designated ECO Silver and ECO Gold, have a powerful circulating pump with more than 30 percent higher pump capacity compared to the predecessor models.

The intuitive menu navigation allows for easy operation. Both control heads are equipped with a mini-USB interface as a standard feature. Additional interfaces are available via the add-on modules. On-the-fly adjustment of the flow between internal and external circulation is made possible even during operation via the new flow rate switch. The more powerful units are equipped with the energy-saving LAUDA SmartCool system. All cooling thermostats are available with air-cooled or water-cooled options.

ECO Immersion thermostats

The immersion thermostats ECO can be used for any bath with a wall thickness of up to 25 mm, a total volume of 50 liters and a bath depth of at least 150 mm by means of the screw clamp included in the scope of delivery.


ECO Cooling thermostats

ECO Cooling Thermostats Energy Saving Star

Silver series
The cooling thermostats with control head Silver are available with the temperature range from -50 up to 200 °C. They are equipped with a bath cover and pump connections for external applications. The pump connections are made of high-quality polymer with an outer diameter of 13 mm. The RE 415 S is the basic model with a small, convenient foot print. The RE 1050 S with SmartCool digital cooling management can be used down to -50 °C and provides a cooling capacity of 700 W at 20 °C. Thanks to the larger baths, both models RE 1225 S and RE 2025 S are excellently suited for internal bath where submersing samples is required.

Gold series
The Gold series cooling thermostats operate up to 200 °C. All Gold series models come complete with a bath cover and pump connection set made of stainless steel with M16x1 threads. The RE 1050 G has an especially high cooling capacity and reaches temperatures down to -50 °C. The integrated SmartCool system ensures remarkable energy and cost savings. The RE 415 G with the smallest of foot prints saves valuable laboratory bench space.
