VALEGRO 250: A Silent, Compact Recirculating Chiller That Tackles Noise, Clutter and Eco-Compliance

JULABO’s VALEGRO 250 delivers a constant 0.25 kW cooling capacity at 20°C in an ultra-compact 24 × 46 × 44 cm frame operating at a whisper-quiet 47–49 dB(A), proving that precise temperature control doesn’t have to hog your lab counter or disrupt your workspace. If you have ever spent a day working at a busy laboratory bench, you know physical space is always at a premium. Fitting another piece of equipment alongside rotary evaporators, analytical instruments, and sample racks often feels like playing a high-stakes game of Tetris.

That is precisely why JULABO designed the VALEGRO 25. A next-generation recirculating cooler built to deliver precise temperature control without demanding half your workspace. As the direct successor to the widely trusted F250, this compact chiller pairs a legacy of reliable engineering with modern digital capability and eco-conscious design.

Solving daily benchtop bottlenecks

Routine laboratory cooling often comes with frustrating compromises. Heavy-duty chillers can be bulky, noisy,and clumsy to control. The VALEGRO 250 targets these common pain points directly:
  • Overcrowded workspaces: Bulky cooling units take up vital bench space needed for primary processes.The VALEGRO 250 uses an ultra-compact footprint (24 × 46 × 44 cm) engineered specifically to tuck easily into tight spaces and crowded setups.
  • Acoustic noise pollution: Loud, continuously humming chillers disrupt focus and degrade lab ergonomics. The VALEGRO 250 offers whisper-quiet operation (47–49 dB(A)) that runs silently in the background without creating unnecessary distraction.
  • Outdated and inflexible controls: Fixed pump speeds and low-visibility dials make precise flow and temperature control difficult. The VALEGRO 250 features an intuitive OLED touch display paired with an infinitely adjustable pressure pump (11–22 L/min, 0.1–0.4 bar) and an operating temperature range of -15°C to +40°C for versatile process regulation.
  • Regulatory and environmental concerns: Legacy equipment relying on synthetic fluorinated refrigerants faces increasing environmental restrictions and compliance costs. The VALEGRO 250 is built using the natural refrigerant R290 (propane) with a Global Warming Potential (GWP) of just 3 to meet modern green lab initiatives and environmental standards.

Why it stands out

The core strength of the VALEGRO 250 lies in its balance of size, noise reduction, and smart controls: it is the smallest, quietest next-generation benchtop chiller in its class.
