VALEGRO 2503H Recirculating Cooler new

with cooling capacities of 1.2 - 2.5 kW

The air-cooled VALEGRO recirculating coolers are environmentally friendly all-rounders for a wide range of cooling and heating tasks. Their working temperature range extends from -20 to +40 °C. The pump can be easily and continuously adjusted as a percentage.

Whether in the laboratory, in research, or in production, the VALEGRO 2503H recirculating coolers provide a constant cooling capacity of 2.5 kW at 20 °C, supporting stable processes around the clock. The modern units provide precise temperature control for a wide range of applications and fit seamlessly into any working environment thanks to their compact design.

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

In addition, the VALEGRO 2503H is highly energy-efficient and environmentally friendly. This is due in part to the use of natural refrigerants. The units were also developed with a strong focus on energy efficiency. In many application scenarios, the use of speed-controlled components results in significant operating cost savings of up to 30%. This means that 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 speed-controlled components offer another advantage: the VALEGRO 2503H recirculating cooler operates extremely quietly. By adjusting the output according to demand, the sound pressure level is significantly reduced – for noticeably quieter and more comfortable operation.
