VALEGRO 2503H Recirculating Cooler new

with cooling capacities of 1.2 - 2.5 kW

The air-cooled VALEGRO recirculating coolers are environmentally friendly all-around units designed for a wide range of cooling and heating applications. Their working temperature range is from -20 to 40 °C. The pump can be user-friendly and continuously adjusted on a percentage basis.

Whether in the laboratory, research, or production— VALEGRO 2503H ’s recirculating coolers provide a constant cooling capacity of 2.5 kW at 20 °C, thereby ensuring stable processes around the clock. These state-of-the-art units offer precise temperature control for a wide range of applications and, thanks to their compact design, integrate seamlessly into any work environment.

During the design of the VALEGRO recirculating coolers, the focus was on maximum user-friendliness. Many helpful features—such as a timer function, a removable venting grid that can be removed without tools, and an illuminated, simple-to-clean level indicator—make daily work easier.

In addition, the VALEGRO 2503H is highly energy-efficient and environmentally friendly. This is due in no small part to the use of natural refrigerants. Furthermore, the units were designed with a focus on energy efficiency. For example, the use of speed-controlled components leads to significant operating cost savings of up to 30% in many application scenarios. As a result, the initial investment pays for itself within a short period of time. At the same time, the lower energy consumption makes a positive contribution to climate protection.

The variable-speed components offer yet another advantage: the VALEGRO 2503H recirculating cooler operates whisper-quietly. By adjusting the performance/output to meet demand, the sound pressure level is significantly reduced—resulting in noticeably quieter and more pleasant operation.
